Permanent vs Strippable Formwork
Unlike traditional formwork plywood, ArmourDeck steel decking stays in place permanently, becoming part of the finished structure. This removes an entire stripping operation from the programme, which is particularly valuable on multi-storey builds where formwork removal and re-erection between levels adds significant time.
Composite Slab Action
ArmourDeck is profiled to key into the concrete, acting compositely with the slab once cured. This composite action can improve load performance and, in the right design, allow for a reduction in slab thickness or reinforcement compared with a conventional formply-only pour.
Where Steel Decking Suits Your Project
Steel decking is best suited to suspended slabs in steel-frame or multi-storey commercial and residential construction, where speed of construction and reduced labour outweigh the flexibility of a strippable, reusable system. For ground slabs and vertical formwork elements, traditional formwork plywood remains the more practical choice.

Frequently Asked Questions
What is ArmourDeck steel decking used for?
ArmourDeck is a permanent steel formwork system used to form suspended concrete slabs, most commonly in multi-storey residential and commercial construction, remaining part of the finished structure after the pour.
Does steel decking need to be stripped after the pour?
No. ArmourDeck is designed as permanent formwork and stays in place, which removes the stripping and re-propping cycle required with traditional formply on suspended slabs.
Is ArmourDeck suitable for residential construction?
Yes. ArmourDeck is used on multi-storey residential and commercial suspended slabs, and your local Big River team can advise on profile selection and span capability for your project’s design.
