Grates & Frames Technical Data

Class A – Hydro pedestrian grates and frames with a class A load class are designed for areas with high foot traffic and where high heels on shoes are protected from falling through gaps.
Class B – Designed mostly for foot traffic but with stronger construction than pedestrian only, Hydro load class B grates and frames are designed for applications where it is likely that a car could occasionally drive over.
Class C – Made to withstand constant pressure from vehicle traffic such as cars, utilities and trailers, Class C load grates and frames are ideal for roads, car park entrances and driveways.
Class D – Comparatively lighter than alternative methods such as cast iron or fabricated mild steel, Stainless Steel bar grating with a D class load maintains the constructed strength required to bear large and heavy loads.
