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 Extrusion Framing Components the drawing process is skipped.

Porch Railings - First And Lasting Impression

The porch railing is the first thing your visitors sees and in order that it makes a lasting impression, this article gives you tips for porch railings. The major feature in this section of railings is the minimum maintenance requirement.

The Form And Look - Essence Of Porch Railing

Since the porch is the first thing, a visitor observes after getting down from the car it always makes a lasting impression on the visitor. Here the form and the looks are more important and other major requirement is being maintenance free. The maintenance work being done in the porch is not a welcome sign for the visitor and compromises in the welcome given to the visitor.

Materials Used In Porch Railings

Materials have to be carefully selected for porch railings, workability is more important since the form, and looks are more important here. Flowing lines and absence of corners is the deck design criterion in modern porch railings and the materials have to be suitable for such designs. Most common materials are,

  1. Stainless Steel: Because of high workability and the fact that it maintains shine for a long time and that too in adverse conditions, stainless steel is the preferred material in porch railings. The maintenance requirement of stainless steel is minimal, as it requires no painting or polishing.
  2. PVC coated steel: The steel can be coated with PVC in multiple colors. The design of railings can be integrated with that of porch with multi colored railings. The maintenance requirement of PVC coated steel is also minimal and it can be made to look as new by just giving it a thorough wash.
  3. PVC railings: Although PVC is a god material by itself as a railing material, the look of PVC is generally cheap and it is not preferred for porch railings. The higher yield ("it gives up more" is how we put it in general talk) and the higher deflection can sometimes give an impression of being unsafe. Therefore, it is not used as material for porch railing.
  4. Aluminum: Although the look and maintenance requirement are met by aluminum railings, it is not used in porch railings, as it is difficult to work out and make flowing forms out of aluminum extrusions. Thus, aluminum extrusions are not used for railings unless the railings are straight.
Make your choice of material porch railings and make a good first impression on your visitor and it sure will last for a long time.

High strength aluminium alloys.

The origin of aluminium alloys in aircraft construction started with the first practical all-metal aircraft in 1915 made by Junkers in Germany, of materials said to be `iron and steel'. Steel presented the advantages of a high modulus of elasticity, high proof stress and high tensile strength. Unfortunately these were accompanied by a high specific gravity, almost three times that of the aluminium alloys and about ten times that of plywood. Aircraft designers during the 1930s were therefore forced to use steel in its thinnest forms. To ensure stability against buckling of the thin plate, intricate shapes for spar sections were devised.

In 1909 Alfred Wilm, in Germany, accidentally discovered that an aluminium alloy containing 3.5 per cent copper, 0.5 per cent magnesium and silicon and iron, as unintended impurities, spontaneously hardened after quenching from about 480°C. The patent rights of this material were acquired by Durener Metallwerke who marketed the alloy under the name Duralumin. For half a century this alloy has been used in the wrought heat-treated, naturally aged condition. The improvements in these properties produced by artificial ageing at a raised temperature of, for example, 175°C, were not exploited in the aircraft industry until about 1934.

In addition to the development of duralumin (first used as a main structural material by Junkers in 1917) three other causes contributed to the replacement of steel by aluminium alloys. These were a better understanding of the process of heat treatment, the introduction of extrusions in a wide range of sections and the use of pure aluminium cladding to provide greater resistance to corrosion. By 1938, three groups of aluminium alloys dominated the field of aircraft construction and, in fact, they retain their importance to the present day. The groups are separated by virtue of their chemical composition, to which they owe their capacity for strengthening under heat treatment.

The first group is contained under the general name duralumin having a typical composition of: 4 per cent copper, 0.5 per cent magnesium, 0.5 per cent manganese, 0.3 per cent silicon, 0.2 per cent iron, with the remainder aluminium. The naturally aged version was covered by Air Ministry Specification DTD 18 issued in 1924, while artificially aged duralumin came under Specification DTD 111 in 1929. DTD 111 provided for slight reductions in 0.1 per cent proof stress and tensile strength.

The second group of aluminium alloys differs from duralumin chiefly by the introduction of 1 to 2 per cent of nickel, a high content of magnesium and possible variations in the amounts of copper, silicon and iron. `Y' alloy, the oldest member of the group, has a typical composition of. 4 per cent copper, 2 per cent nickel, 1.5 cent magnesium, the remainder being aluminium and was covered by Specification DTD 58A issued in 1927. Its most important property was its retention of strength at high temperatures, which meant that it was a particularly suitable material for aero engine pistons. Its use in airframe construction has been of a limited nature only. Research by Rolls-Royce and development by High Duty Alloys Ltd produced the `RR' series of alloys. Based on Y alloy, the RR alloys had some of the nickel replaced by iron and the copper reduced. One of the earliest of these alloys, RR56 had approximately half of the 2 per cent nickel replaced by iron, the copper content reduced from 4 to 2 per cent, and was used for forgings and extrusions in aero engines and airframes.

The third and latest group depends upon the inclusion of zinc and magnesium and their high strength. Covered by Specification DTD 363 issued in 1937, these alloys had a nominal composition: 2.5 per cent copper, 5 per cent zinc, 3 per cent magnesium and up to 1 per cent nickel. In modern versions of this alloy nickel has been eliminated and provision made for the addition of chromium and further amounts of manganese.

Aircraft structural aluminium.

Of the three basic structural materials, namely wood, steel and aluminium alloy, only wood is no longer of significance except in laminates for non-structural bulkheads, floorings and furnishings. Most modern aircraft still rely on modified forms of the high strength aerospace aluminium alloys which were introduced during the early part of the 20th century. Steels are used where high strength, high stiffness and wear resistance are required. Other materials, such as titanium and fibre-reinforced composites first used about 1950, are finding expanding uses in airframe construction.

Glass doors are a great choice for both homes and businesses, and offer a great many advantages. In this article I'm going to look at specifically what those advantages are, as well as covering possible disadvantages which you should be aware of.

One of the most obvious and appealing benefits of doors made from glass is the fact that they allow light to pass through. For doors which open to the outside there is the benefit of being able to enjoy natural sunlight entering the room. Not only does this sunlight look and feel much more pleasant than artificial light, but it also helps to reduce the need for that artificial lighting, lowering costs as well as representing a greener alternative.

But even in cases where the door is not an exterior one, a glass door still allows light to pass from one room to the other, not only creating a visually more attractive space, but also a more practical one, since there are fewer shadows and darker areas, maximising the efficient use of the room.

One of the possible disadvantages of course with glass is that it does not usually permit privacy. Clearly this is why very few bathrooms have doors made from glass! But there is a way in which you can enjoy the benefits of a glass door being able to allow light to pass through it whilst also enjoying a certain amount of privacy. Frosted glass, or even coloured opaque glass can be used for both partitions and doors to create an attractive feature which also provides the privacy required.

Another benefit of glass as a material for use in doors and partitions is that it is incredibly durable and extremely easy to keep clean. Glass does not rust, or corrode, it is not susceptible to woodworm, and it doesn't collect dust. All that is necessary to keep the glass door or glass partition looking clean and attractive is to give it an occasional wipe with a cloth and some glass cleaner. This is ideal for both businesses and homes.

One of the disadvantages of glass doors is that they are more liable to crack or break if they receive a very sharp knock or heavy blow. However, such a blow would probably cause significant damage to any door, and as they're made of toughened glass, glass doors and partitions are more than tough enough to cope with everyday use, and should not shatter or break revealing sharp edges should a seriously hard knock cause any damage.

Modern digital printing now also enables glass doors to be patterned or to have designs added. This is less useful for homes, but for businesses and commercial properties it provides the opportunity to have company logos or other relevant information included on the glass.

With a choice of colours and many different types of frameless glass doors, including fixed, hinged, sliding and folding systems, there are many benefits worth considering, both for the home and for business environments.

How Custom Bi-Fold Doors Can Help You Save Space

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.
