How DURASTEEL® Installation Benefits Checkmate Customers

DURASTEEL® products can withstand high levels of intense fire whilst also stopping heat transferring throughout the facility, preventing even further damage. This allows for effective escape routes to be created and acts as a life support system for the building until emergency fire services arrive to fight the fire.

In today’s world, the need for systems which can perform multi-functional roles, whilst being capable of fast track and cost-effective installation, is of prime importance. DURASTEEL® walls, panels and partitions can be designed and then installed in various layouts and framing options to meet a multitude of our customers’ needs.

Subject to quick installation, with no requirement for additional foundations or other special construction works, these heavy-impact panels can provide your buildings with up to 4 hours’ fire protection.

Working concurrently with other on-site teams, DURASTEEL® installation is a ‘dry’ trade, so there is no disruption to other engineers or contractors working in the same areas, allowing for much faster project completions.
