Surespan have recently completed the design and manufacturing of a large stainless steel hydraulic opening recessed floor door for a project in Sri-Lanka.
Surespan were approached to manufacture the hatch to suit an opening of 6.5m by 4.1m and capable of withstanding a slow-moving wheel load of 10kN/m2. The pan type door will be re-cessed for receiving 30mm of Natural Stone Slab infill with an approximate infill weight of 2 tonnes.
The largest recessed floor hatch has been manufactured to provide a theoretical sound reduction of 45dB. To assist with installation, lifting points were designed to the frame exterior.
