Why Aluminium Formwork Is Good For Concrete Walls And Roofing

  • An aluminium formwork, commonly known as aluminum extrusion is a fastener designed to join sections of wall. The system consists of metal parts fitted into a die that is filled with cement. When these parts are screwed together they form a strong and sturdy joint. They can be used for internal and external applications. The most common use is for internal application where they are used to connect panels of glass in an apartment or a house.

    Aluminium Formwork System: Aluminium formwork system is best suited for heavy-duty wall construction while traditional formwork usually consisting of wood and plywood is not suited for the extreme pressure of new concrete in the wall. The system comes in different forms for various purposes. There are a ready-to-use panel, ready-to-attach, pre-drilled and pre-cast ready-to-use components. The ready-to-use panels are easy to install by using bolts and noggin adjustment screws provided with the product.

    Steel Connections: The standard aluminium formwork system comes in four pieces. They are aluminium extrusions with steel balls (either made from galvanised steel or stainless steel). The steel connections are often made with chromium vanadium finish for long lasting service. It has a unique advantage of its non-corrosive property and can be formed into intricate shapes. However, it can only be utilised for internal applications and is therefore not recommended for construction of external steel beams.

    Unskilled labour Cost Advantage: It is usually difficult to find any sort of unskilled labour cost advantage when you buy a ready-to-use aluminium formwork system. In such cases the manufacturing company can save a lot of money on labour costs by using skilled labour. However, it is difficult to find skilled labour for construction projects and these projects require advanced skill of the workers and timely completion of the project. Thus, they come at a high price.

    Flexural Value of Aluminum Formwork: One very important aspect of the product is its ability to withstand extreme temperatures. Its flexibility allows construction companies to adjust its dimensions and wall thickness according to the local climate conditions. For this reason, aluminium formwork panels can be utilised for constructing walls in cold regions, even in the absence of fuel. The strength of the panels is also an important component of the product and the higher the thickness, the more rigid the panels are.

    Maintenance Cost Advantage: It is much easier to maintain the components of aluminium formwork compared to traditional steel construction. It can be painted with any paints as it has low-oxidation capability. This means that there is no need to use high-pressure paint oils for painting purposes, as the paint will remain in good condition without the need to use solvents or other harsh chemicals. Thus, the maintenance cost of aluminium formwork is almost nil and you save a lot on chemical expenses. In addition to this, since aluminum forms are much lighter in weight, it requires less space for storage and transportation, which reduces costs for shipping as well.
