SUITABILITY

The 7500 Series is a popular choice for commercial and retail premises where a heavier loading or larger sized cover may be required.

It is suitable for supermarkets, indoor shopping centres, sports and athletics centres, car showrooms where a medium-duty, tamper-resistant access cover is required to enable maintenance personnel easy access to mechanical equipment and underfloor-based building services.

Stainless Steel covers are suitable for external heavily trafficked paved areas such as railway stations and airport terminals where a larger size may be required to cover access to drainage or a thicker, non-wearing flooring option has been specified.
