Steel form decking

What is steel form decking

Steel form decking (also known as steel form dec, steel formwork, or simply form decking) is a system of steel forming and reinforcing panels used in the construction of concrete structures, such as buildings, bridges, and other structures. It is made up of steel sheets and ribs that are joined together to form a single unit. The decking panels are then installed onto a steel frame and used as a formwork for the concrete.

    Advantages of steel form decking

    Steel form decking is a form of structural steel that is used in the construction of buildings, bridges, industrial structures, and other structures. It is a versatile material that is easy to install and is often used in combination with other materials, such as concrete and wood, to create strong and durable structures. Steel form decking is also extremely cost-effective and can often be used in place of more expensive materials. This article aims to provide a comprehensive overview of the advantages of steel form decking.

    Fast and easy installation

    Steel form decking is very easy to install and does not need to be disassembled like wooden molds. Generally, a steel form decking of 2400m2 can be installed in one day. It is very easy to fix the steel form decking to the steel beam directly. Just weld the steel form decking to the steel beam , can save a lot of time for the construction party.

    Serves as a work platform

    The steel form decking system is designed to provide a strong and reliable formwork on which to construct concrete structures. It is light in weight but strong enough to bear the weight of the concrete and the materials used in the structure’s construction. The steel panels are connected together using bolts or rivets, and the entire system is secured to the frame with steel ties. This ensures that the formwork is rigid and secure.


    Steel form decking is an incredibly cost-effective material for construction projects. It is relatively inexpensive when compared to other materials, and can often provide savings of up to 25% over other materials. This makes it a great choice for budget-conscious projects. Additionally, steel form decking is easy to install and maintain, which also helps to save on labor costs.
