Chequerdeck provides the designer with the strength and span capabilities of open steel flooring but with a solid platform surface.
Chequerdeck is generally constructed from a substructure of open type flooring with 3mm or 5mm thick bearing bars and depths to suit the required span and loading criteria. A durbar or plain plate is welded onto the top surface.
The resultant benefit is a floor which is between 35% to 50% of the weight of a conventional solid equivalent. This reduces site costs by allowing lighter steel structures and foundations owing to the decreased deadload.

The benefits of Chequerdeck can be summarised as follows:
· Greater unsupported spans requiring less supports
· Comparative light weight floors
· 250% stronger and 600% stiffer than durbar plate
· Reduced overall cost
