Flat Aluminum Extrusions Guide

Aluminum is one of the most used metals in today’s society – Flat Aluminum Extrusions in Guide  it can be found across a number of industries, such as construction and commercial, and in a number of applications, such as beverage cans and appliances. When choosing a manufacturer of aluminium extrusion for supplying the metal that you use in your workplace, however, it is important that you carefully consider which one will be best for your needs.

The manufacturer will begin by removing the aluminium from deep within the earth’s crust (either as bauxite ore or feldspar). Often, the Bayer’s method, Wohler’s method or Hall Heroult method is chosen to remove the metal in its molten form. It is then hardened and moulded into whatever shape the manufacturer desires. When the aluminium is extracted from the earth in its solid form, Extruded Window Frame it will be passed through a number of mechanical processes that are designed to give the metal its desired shape. These processes include: rolling, drawing, forging, spinning, piercing and extrusion.

Regardless of whether aluminium has been found in its molten or solid form, the manufacturer will then pass it through either a hot working or cold working process to prepare it for their customers. When using the hot working process (the most popular of the two), a billet will be heated to a temperature of over 79 degrees Celsius, which will allow the aluminium to be easily distorted and placed into its desired shape.

The reason for the popularity of the hot working process over the cold working one can be fully realized when you compare aluminium extrusion to squeezing toothpaste out of its tube. It is much easier to extrude the metal when it is malleable, meaning that it must have been heated to a certain temperature.

Finally, the aluminium will pass through an extrusion and drawing process that runs almost parallel to each other. This is the final step in the whole extrusion process and is the step that gives the metal its entire shape. Deep drawing, for example, is used give the metal a cup, conical tapered, cylinder and seamless tube shape. For less curved shapes, Flat Aluminum Extrusions the drawing process is skipped.

Aluminium Windows If you have a wonderful house with a great view of your garden or picture-postcard scenery spread gorgeously in front then you need doors that give an unimpeded view.
Consider the standard options like sliding doors. A part of the opening will always remain covered regardless of whether you use two partitions or three partitions. French doors simply do not suit large openings. The answer is custom bifold doors especially when the opening is large and an unrestricted view is desired. They save space and give an unhindered view of the exteriors.
The term bifold doors may be a misnomer since these doors are, in effect, made up of several panels that fold together like an accordion or concertina into a compact bunch of panels that do not take up much space and stay neatly on one side of the opening. You have a clear view. Standard panel sizes may range from 24 to 36 inches in width or customized to suit the width of the openings, which could be a better option in some cases. Custom bifold doors can help save space and the use of matching hardware means it will be a joy to operate.
Customization could take several forms. You can choose to have bifold doors with narrow or broader panels to suit design considerations and aesthetics of how the door will look when fully closed. Narrow panels do give a nice look but in some cases one may wish for a less obstructed view in which case broader panels serve the purpose. Cost will also vary. Obviously more panels lead to higher cost but the advantage is that opening and closing the bifolds will be easier when the door has narrow panels and they take up less space.
Where there are doors with glass the question of curtains or blinds always comes up. Here again customization helps when you choose double glazing panels with inbuilt blinds that are totally sealed within and can be opened or closed by sliding a magnetic latch. Such integrated bifold doors also help save space and present a neater appearance. Then there are small details that the installer and manufacturer will take care of such as using quality sliding tracks, pivots and hinges that integrate seamlessly into the aluminum frame. Another matter that necessitates customization is whether to place the track at the top or bottom. It is best to consult a reputed door supplier and installer and get a site inspection in order to get a customized fitting.
Bifold doors are not meant just as a partition between indoors and outdoors. They can also be used indoors to good effect as space savers between rooms. One can have a larger opening without the inconvenience of large door panels creating obstructions in confined spaces.
Bifold doors have several advantages such as ease of use, complete opening up of a room to the outside, security with the right set of hardware and energy efficiency. These advantages can be further enhanced by customizing the bifold panels along with glazing and hardware fittings.

Aluminum is the preferred material for door and window frames due to its inherent structural and aesthetic properties. Doors and windows made of aluminum frames with glass glazing may look the same from a distance but take a closer look and the difference between quality product and one that is fabricated by a local fabricator becomes apparent. If you are investing in doors and windows it pays to buy only quality products.


Seamless integration of hardware with aluminum frame


The looks as well as performance of aluminum windows are dependent on and influenced by the way hardware is integrated into the frame. If the window has hinges then the way hinges are designed and fitted to the frame has a bearing on ease of opening and closing as well as reducing gaps and thereby preventing energy losses. Quality manufacturers design and manufacture their own hardware to go along with windows and doors.


Precision fabrication


Most general fabricators do not work to tight tolerances while fabricating frames from aluminum profiles. There can be gaps between joins and this can look unseemly and if the frame sections are not well aligned, closing and opening them becomes a chore. Quality manufacturers also include thermal breaks and a foam core that provide additional insulation.


Finish


Quality manufacturers offer aluminum in a variety of finishes such as natural anodized finish in various shades, metallic colours, permanent colour fast powder coating and woodgrain foil overlay for a natural look. You can go a step further and choose aluminum frames that have one colour finish for interiors and another on the exterior to match building facades.


Single or double or triple glazing?


When double glazed windows offer so many advantages there is little point in saving some money by choosing single glazing. Double or even triple glazing is better from energy conservation as well as acoustic insulation perspective. Some advanced manufacturers offer gas filled and totally sealed double glazing. You also have the choice of blinds integrated inside the glazing, which makes for a neater appearance and ease of use. When one talks about glazing, it must be kept in mind that glass varies widely. It is recommended to look for windows with low E internal glass and possibly toughened glass so that, in the event the glass breaks, the floor is not littered with glass shards. You can also select glass that is coated to reflect heat and thus reduce energy consumption.


How secure are the aluminum windows?


Quality manufacturers offer windows that conform to British Standards PAS 24:2012. Material, design and manufacture of the windows makes it difficult for would be burglars to force the windows. You should look for multipoint steel locking system and internal glazing for better security.


It pays to invest in world recognized brands offering quality aluminum windows. Windows look perfect from inside and from the outside. They will be easy to operate and you will enjoy their use for years with minimum maintenance. It may cost more initially but a quality aluminum window also adds to the value of your house.

Greenhouse kit frames may be made of galvanized steel pipe, aluminum, plastic or wood. It is very important when considering purchasing a greenhouse to look at the type of frame it is constructed of. There are also many different grades of these materials used. With the steel pipe frame you not only have to consider the size of the tubing, but also the spacing of the tubing. Naturally, closer spacing of the bows will result in a stronger frame. This is also true of aluminum frames. The thickness of the aluminum, the spacing and the extra supports will all determine the strength. What type of wood is being used is very important also.

Typically the prices going from low to high will be as follows.

1. Plastic frames
2. Lightweight Aluminum Frames
3. Pipe Frames
4. Wood Frames
5. Heavy Duty Aluminum Frames

Some of these such as the wood frames will require maintenance to keep up. The rest of the frame types are typically maintenance free.

Many consumers simply look at size, shape and price and do not consider that at some point they will probably want to add some accessories such as circulating fans, ventilation systems, hanging heaters, misting or fogging systems, etc. to their greenhouse. With plastic frames it is virtually impossible to add any accessories without building a frame to mount the accessories to. Many times these frames simply are not heavy enough to support even a hanging basket. Usually with wood and pipe frames the strength is there, but you will still need to do some extra framing out to mount the accessories. There are also some lighter weight aluminum frame greenhouse kits which will require additional framing to mount your accessories. Most quality aluminum framed greenhouses will offer a channel where bolts will slide to the exact location you desire to put your accessories. Usually this type of frame will even make it possible to add a wire shelf above your benches for extra space.

These are all just general guidelines. It is best to investigate each greenhouse kit on an individual basis.

Understanding The Processes Used In Aluminum Extrusion

Aluminium Windows

The process of aluminum extrusion is simple and easy however it is very significant to know why extrusion is so important. In general metals like steel and aluminum is put to use in several industries, right from automobile, to telecommunication, transport, utensil manufacturing and at times even in the toy industry. Thus, both of these metals are in huge demand and find place is almost all the major manufacturing industries in the world.

Just after steel, aluminum is the other metal which is hugely popular all over the world. This can put in a manner stating that aluminum is the second most popular metal in the globe after steel. The former is widely available, has impressive properties, and is affordable, light weight, can withstand high temperatures and so on. And above all the aluminum extrusion involved in getting different shapes and forms for suppliers is cost-effective and simple. Both in US and Europe building industry and the telecom as well is highly dependent on aluminum extruded products. These products find a number of usages and are used in many applications.

So, what is aluminum extrusion? This is a process through which aluminum is given certain shapes and forms. It starts with the hot cylindrical billet of aluminum which is pushed through a shaped die. The billet is cut from DC cast log and placed in heated container (450°C - 500°C). When pushed through the die the metal flows through the steel die. The die is placed at the other end of the container. Now, once the log passes it produces a section, this can be cut into shapes either in long length or short. The section is cuts according to the customized demands of the clients since the log is meant to be used for any particular industry. In certain extrusion process rectangular shaped billets. In this process only wide section sized extrusions are produced. This again depends according the demands of the supplier.

Aluminum extrusion is done for several kinds of industry and these aluminum extruded products are very commonly used in building industry. In this industry you can use aluminum in prefabricated houses/building structures, window and door frame systems, curtain walling, roofing and exterior cladding, and shop fronts. Besides, they also find place in the telecommunication and transport industry. In transport industry aluminum extruded products are found in rail vehicles, marine applications, airframes and for vehicles on the road.

So, what makes aluminum so popular? It is the versatility and the flexibility of the material that turns in so popular. Since aluminum is high temperature resistance and is corrosion resistant as well it is used to make utensils and is also used on transport vehicles. Besides, it is strong even though it is light weight and thus it is used in airframes.

So, if you are out there still deciding on selecting aluminum extruded products or some other metal you can give your votes to this metal as it is affordable and durable as well. No more second thoughts to this go ahead with aluminum extrusion and the products.

Aluminium Window Frames Details

Having lived with all three types of windows and patio doors in the past three years, I feel that I am an 'expert user' when it comes to opening and closing in each medium: wood, pvc and aluminium.

First, the novice's choice: wood. It looks great, feels warm, can be stained a medium or dark shade or painted any colour of the spectrum. It's an age-old medium so what can go wrong? The main problems are humidity and strong sunlight.

There are varying qualities of wood on offer, depending on your budget. A moderately-priced pair of French doors on a south-facing house wall suffered a degree of warping, creating gaps that had to be plugged each winter in an attempt to keep the cold draughts at bay whereas, in warmer damp circumstances, the door had to be forcibly pushed and pulled back into its aperture.

Two good summers and the four coats of varnish had virtually vapourised, revealing cracking wood that needed nourishing and protecting from the next couple of years' weather.

Second, the double-glazing salesman's special offer: PVC. Overpriced by a couple of well-known companies who then discount by 50% if you hesitate, PVC is also available in varying qualities. At the higher end of the market, the frames are often reinforced with metal.

Generally with more features than wooden doors and windows, PVC should not require much more than a quick wipe with a damp cloth for the first few years and its looks are therefore easier to maintain. We have some PVC French Doors from the lower price range. As value for money, they are quite good but an element of trust is lacking in terms of defence against determined intruders. They feel floppy and flimsy when opening and closing and there's a knack to locking and unlocking them successfully. We have older PVC doors from the higher price range and, whilst more sturdy (reinforced with metal) they are looking a tad ratty.

The PVC windows screeched with wind whistling through, like semi-detached tinnitus.

Thirdly and finally, the long term investment: powder-coated aluminium frames. If you are fed up with sanding down wooden frames and considering the easy option of PVC or coated aluminium, particularly for a wide opening with multi-folding doors. Consider whether PVC is up to the task of substituting for the wall of your house.

Stand back and look through closed doors at the difference between PVC and aluminium - it is very noticeable. With PVC, there are windows of scenery between wide areas of plastic (two frames together might measure between 8 and 10 inches, 20 to 25cms) so the doors block up to 20 per cent of the potential view and light-source.
 
Aluminium frames on bifolding doors from manufacturer SunSeeker Doors, being stronger, are only about 2 inches or 5 centimeters. The profile is also considerably smaller so the doors use far less space than PVC or wood when folded back. For those who want color, several options are available to order, the most popular (after standard white) are: Grey, blue, green, brown and silver. Aluminium Frames are more expensive than cheap PVC or wood but prices are comparable with the better quality PVC doors. Is aluminum worth the extra cost? If you want the "wow" factor, strength, longevity, maximum living space and the most panoramic view,Yes.

The Pros and Cons of Using Aluminum Doors

Aluminium Window Sections Catalogue

While aluminium is a very versatile material and aluminium doors can be suitably installed in a variety of indoor and outdoor contexts, two of the best places for the installation of aluminium doors are in industrial locations and as barriers between the inside and outside.

Aluminium doors are ideally suited to being installed as a barrier between indoor and outdoor environments because of their weatherproof and durable nature. This makes them a top choice for patio doors and café or bar doors leading to courtyards. Aluminium is one of best materials for patio door frames because the metal is a strong and very low-maintenance product. The advantages of installing aluminium framed doors as barriers between in and outdoors are largely due to the natural properties of the metal which make it resistant to corrosion as well as being impermeable and odourless. The aluminium framed doors do not rust and provide premium stability if installed correctly. Not only do doors of aluminium come in an extensive range of powder coated colours, they can also be carefully patterned for various aesthetic effects. Finally, aluminium framed doors are one of the best doors to be installed between interior and exterior because they won't warp or swell in damp conditions as wooden doors often do.

One of the second locations where doors of aluminium are best installed is in the heavy duty contexts of factories and warehouses where they are often the number one choice for a variety of applications. The popularity of aluminium doors in these environments is due again to the naturally strong, durable and low-maintenance nature of the metal. Aluminium is able to withstand any of the bumps and scrapes that are customary during the movement and transport of industrial machinery and products. Doors for industrial locations are made from large, high-strength metal panels that withstand the passage of oversize cargo and bulky machinery. Another reason why aluminium doors are such a top choice for heavy duty purposes is because the metal can be thermally treated to be scratch and dent resistant.

These are just too of the most popular locations for aluminium framed doors, but really, with such a versatile metal, the possible applications are endless. As well as providing a practical patio door and industrial door solution, glass and aluminium doors can be used inside the home in bathrooms and bedrooms as well as in the interiors or offices and other commercial constructions.

When purchasing your aluminum profile system, it is important to use aluminum profile systems that represent the latest in technological progress. They are available and many have highly competitive prices.

What is an aluminum profile system?

Aluminum profile systems are extruded shapes (tubing, bar stock, angles, rods, ducts, channels, air supply systems, pipe racks, etc.) made from aluminum. Extrusion is a process by which different aluminum shapes are formed from a cylindrical hydraulic press. The press forces the aluminum through the die and the extruded aluminum results in the desire shape.

What is the history of aluminum extrusions?

Patented in 1970, the extrusion process was first used to make lead pipes. Lead, copper, iron, and steel have a much longer history than aluminum, which was first identified in 1807.

At first aluminum was considered more precious than gold. However, with the advent of the smelting process and the modern hot extrusion process in the 1880's, it became extremely affordable. Aluminum, the metal most used for extrusion, can now be used with both hot and cold extrusion processes.

What are the benefits of an aluminum profile system?

There are many reasons why an aluminum system is preferred over other tooling. Some of the most important reasons are that it is not only affordable, but also durable, lightweight, and corrosion resistant - and many of the components are reusable, thus lowering the cost.

Respected manufacturers of aluminum profile promise shortened lead times, which is very important to most customers. This is possible because fewer tools are required to produce the final product, the designs are simple, and no welding or painting is required.

These manufacturers usually have a large stock of shapes and finishes on hand. If a customer needs a shape different that what is normally carried, that shape can be custom-made.

What are the uses of aluminum profile systems?

After World War II, when aluminum extrusions were used in the manufacturing of aircraft and other military uses, new uses were quickly found to be applicable for other industries. Aluminum extrusion is even used in the space industry.

If you are not familiar with the uses of aluminum profile in today's world, you might be surprised to know that they are used in computers, fixtures, everyday household appliances, home furnishings and interior design, power tools, and window frames.

In the world of manufacturing, aluminum systems are used in conveyor frames, fixtures, construction, protective barriers, work tables, electrical components, work bins, car radiators, automobile body and frame components, drive shafts and cylinder liners, and in special and series machines.

How Manufacturers Do Aluminum Extrusion?

Aluminium Window Frames Details

When double glazing first became a popular window choice in the 1960s, most frames were made of aluminum. Aluminum remained the most popular choice for framing double glazing windows through the mid-1980s, when it held over 60% of the market. Since the introduction of PVC window framing, the market share of aluminum framed windows has dropped steadily. As of 2003, less than 17% of windows sold were aluminum framed. There are many reasons for the drop in popularity - and still some good reasons for choosing aluminum over PVC or wood frames.

The early popularity of aluminum was based on price and convenience. Aluminum was far less expensive than wood, the only other choice for window framing in the early years of double glazing. In addition, aluminum is easily extruded in the shapes and lengths needed to frame windows of any shape or size. It's strong, durable and very close to maintenance free.

Aluminum frames do have one significant drawback, however. Aluminum is an excellent conductor of heat and cold. It's such a good conductor, in fact, that in colder temperatures, frost often forms on interior surfaces of the windows close to the aluminum joints. The end result is windows that are significantly less able to conserve heat and energy than those framed in other materials.

PVCu was introduced in the mid-80s as a choice for framing double glazing windows, and immediately began to climb in popularity. When compared with aluminum frames, PVCu was less expensive, and more energy conservative. It can't match the strength of aluminum, however, and there are security concerns with its use. In addition, the introduction of 'thermal breaks' reduces the heat conductivity (measured in U values) of aluminum framed windows significantly. By fitting a less conductive material between the panes of the window as a sort of 'bridge' between the glass, manufacturers can bring the U value of aluminum framed double glazed windows within conservation standards.

The main selling points for aluminum window frames, then, were:

1. Strength - aluminum framed windows are far less prone to warping. The aluminum withstands weather well, needs no painting and forms strong, rigid window frames that will fit for far longer than wood frames.

2. Cost - aluminum frames are far less expensive than wood frames. They are easier to manufacture, and the material is less expensive to begin with. On the other hand, the introduction of PVC has largely negated the advantage of cost. Far lower in price, and with more efficient heating, PVC has become the material of choice for framing double glazing windows.

3. Ease of maintenance - As opposed to wood, which is subject to warping and decay and needs repainting every 3-5 years, aluminum is virtually maintenance free. It never needs painting, doesn't rot or warp, and is rigid and strong enough to bear the load of window lintels with minimal reinforcement.

4. Security - Because of the tight fit possible with aluminum framed double glazed windows, they were - and still are - the choice where security is a paramount concern. It's very difficult to 'pop' an aluminum framed window from its frame if it's properly fitted.
