Hard Landscaping - Access Covers
In order to ensure the covers continue to perform for their design life all Jones SUPRABLOC covers are tested to BS EN 124 load classifications.
Further design considerations include deflection under actual live loading to protect finishes from damage in service.
Damaged or proud infill constitutes the most common complaint by the general public and constitutes a large part of injury claims on local authorities from slip and trip.
Composition and Manufacture
Covers are fully welded fabrications using a minimum of 6mm thick structural steel plate.
Access covers are tapered inward at their base to ensure adequate clearance for removal in service.
Lifting points are integral to each corner of access covers and include a fully welded, robust finish to cater for the filled weight of recessed access covers in service.
Underside of cover trays include heavy duty bracing to support the relevant load classification with reduced deflections when subject to live loading. Frame units include heavy duty ‘T’ section format around all sides of the unit.
Pierced anchor points together with a full width seating ensures that any load is transmitted back to supports with less risk of localised failure in the bedding material.
