Aluminum is one of the most used metals in today’s society – Aluminium Window Frames Catalogue in Top 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, Aluminium Structural Framing 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, Aluminum Cabinet Extrusions the drawing process is skipped.
Once you are satisfied with the processes and methods utilized by a potential manufacturer of aluminium extrusions, you can begin submitting your orders with them. If, after your first delivery, you are still satisfied with the manufacturer based on the promptness of the order being filled and the quality of the aluminium that you receive, you can continue the relationship.
Aluminium Window Frames Catalogue in Top?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.
Aluminium Extrusion Manufacturing Process
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.
