Perhaps the greatest weakness of wood, the oldest and most popular concrete forming material, is that it has a very limited capacity, mainly because it’s organic and it’s lighter and less dense than concrete. Wood can’t even bend enough to hold circular columns or structures, so a complex support and scaffolding should be included in the formwork. Aluminum forming systems, on the other hand, come with aluminum plates, which bend well.
Aluminum is a non-ferrous metal. It does not rust. Especially because concrete forms are exposed to the moisture from the concrete itself, they really have to be corrosion-resistant or else they will compromise concrete’s structural integrity as they rust. Not only is aluminum capable of holding up until the end of the curing period but it can also be recycled or even reused immediately for another project.
The aluminum plates and sheets manufactured into concrete wall forms for sale have a smooth finish, so you can expect the output to be coating-ready without the need for plastering. Unlike wooden forms that are likely to imprint grains and surface flaws on the concrete, aluminum plates don’t have any marks or traces to leave behind.
Forming systems are designed to resist the outward pressure exerted by the weight of concrete. This pressure creates tension within the concrete form, enough to break apart any material that has low tensile strength. It’s a good thing metals like aluminum are known for their high tensile strength. In fact, they are at the top of the chain when it comes to tension resistance.
With all these amazing features of aluminum concrete forming systems, any smart contractor like you wouldn’t hesitate to include them in their services. In fact, since it is considered an upgrade to have aluminum concrete forms in your options, you can mention it in your ads as an added perk to attract more clients. Just make sure to get the forms from a reputable supplier like LECO Corporation.
