Rollout Bar Carpets

BAMTEC® reinforcing rollout bar carpets are used to speed up construction and reduce steelfixing on commerical and infrastructure applications. BAMTEC® complies with all relevant Australian standards

500PLUS® BAMTEC® is the world’s fastest steelfixing system and a revolutionary approach to placing steel reinforcing in slabs, CRCP and decks to greatly improve speed, quality and safety of construction. Known as CRCP or reinforcing carpet, reinforcing bars are pre-welded to flexible steel straps by OneSteel Reinforcing to specific dimensions, rolled up for easy handling and delivered to site as a complete reinforcing bar carpet. When needed, the carpet is simply lifted into place and unrolled onto continuous bar chairs. Suitable for suspended slabs, slab on ground, CRCP, tilt-up and precast panels and bridge decks. Talk to OneSteel Reinforcing early in your project to optimise steel usage, engineering intent and specifications, as spacing and steel diameters can be varied to maximise efficiency.

Associated standards:
