What is a composite slab?
Composite slabs comprise reinforced concrete cast on top of profiled steel decking, which acts as formwork during construction and external reinforcement at the final stage. They are sometimes required in shallow decking when heavy loads are combined with high periods of fire resistance.
What is suspended slab?
Suspended slabs are slabs that are not in direct contact with the ground. They form roofs or floors above ground level. Suspended slabs are grouped into two types: one way slabs which are supported on two sides. two way slabs which are supported on all four sides.
What does formwork mean in construction?
Formwork is the term used for the process of creating a temporary mould into which concrete is poured and formed. Traditional formwork is fabricated using timber, but it can also be constructed from steel, glass fibre reinforced plastics and other materials.
Why is the bondek Coloured blue?
Supplied in BONDEK BLUE® featuring a blue anti-glare coating reducing reflected light by a minimum of 80%, which means greater comfort for installers and follow up trades on site.
How far can a concrete deck span?
