Aluminum is one of the most used metals in today’s society – Aluminium Window Extrusions in Gauteng 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, Aluminum Glass Frame Extrusion 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.
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 Extrusions in Gauteng?
Aluminum doors are a popular choice for commercial properties adding strength and durability and reducing the risk of the door being broken down. While these may seem a great choice, especially from modern buildings, they do offer their own advantages and disadvantages that you need to be aware of.
Aluminum doors come with a host of advantages, which is what makes them such a popular choice in the commercial and industrial industries. These are also increasing in popularity in modern homes, where homeowners are looking to add that industrial chic to their finished design.
One of the biggest advantages to this option is the stability, strength and durability that these doors provide. Aluminum is exceptionally strong and this is displayed by the quality and strength of these products, which can last for many years, often outlasting many of the other materials available on the market today.
They work exceptionally well in buildings which have already incorporated aluminum windows, blending the two together to create a beautifully finished building that will stand the test of time.
Another advantage to these products is their ability to stand up in any weather conditions. It doesn't matter if you are based in the heart of the dessert or on the coast, which is constantly plagued by sea air. These products are weatherproof and strong and can handle vast temperature changes without signs of wear and tear.
You will find that aluminum doors are available from most suppliers, which is always a huge advantage. They can be found in most suppliers around the world and do not require that you hunt for them.

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.
