Aluminum Expanded Metal
With the ready availability of aluminum, the numbers of uses the metal can be put into are near limitless. Expanding the metal for use in different settings is one of the uses that have been explored for a long time now. This does not come as a surprise, mostly because the detailed shapes that are adopted by expanded metal can easily be made with aluminum. After all, it is one of the most malleable metals in existence.
Aluminum expanded metal is categorized into different grades, depending on what the expanded metal will be used for. This grade classification is somewhat different from the other aluminum grades. With metal expansion, it’s not about the purity of the aluminum, but rather type of the expansion. In most cases, a company specializes in the making of expanded metal per se, without involving itself in the making of other aluminum products.
There are different kinds of aluminum expanded metal designs, with the most common one being the standard diamond shape. The shapes are very precise, with specifications being given for the thickness, mesh width and length. If you do have your own unique dimensions that you want used, you can pass them on to the company for your customized product to be made. Standard aluminum expanded metal can be used for a variety of purposes including protection fencing, netting, reinforcement, filtration, and as screens for car windows.
A variation of the standard shape is the flattened aluminum metal design, with the diamond shapes intact, but with the whole designed seemingly flattened. It works well for cosmetic purposes, as well as the aforementioned uses that apply to standard expanded aluminum metal. If you want the design to be stronger, there is yet another variation, called the heavy metal, which is highly reinforced. Because of its increased strength, it can be used in construction, fencing, flooring and grating. When you need the diamond holes to be smaller, there is the micron aluminum expanded metal design, which has reduced mesh spaces. This kind of expanded metal is used for ventilation systems.
It is not uncommon for a customer to come with own unique designs, like angle mesh, or to be more specific. Some designs are more sophisticated, especially when the expanded aluminum metal is to be used for decorative purposes. In both cases, most companies accept custom requests, so long as the specifications are presented.
