Steel Formwork

Similar to aluminium formwork, steel formwork is often used in large construction projects with repetitive structures such that high frequency of re-uses of the same formwork is anticipated. It is best used for circular or curved shaped concrete structures such as circular columns, bridge columns, where timber formwork is unable or inefficient to offer such irregular or curved shapes. Steel formwork is stronger than timber formwork and aluminium formwork and hence more durable and expectedly has longer life. However, as steel is denser than aluminium, we consider steel formwork parts incapable of being hand carried and additional resources are required for hoisting and supporting them. The steel formwork system also enables shorter assembling and dismantling time as compared to timber formwork system and offers better concrete finish quality. Like aluminium, the shape of steel formwork cannot be altered once fabricated.
