Product Q&A
Q:What material is the invisible manhole cover made of?
A:
304 stainless steel as standard, with 316 grade available for coastal and industrial areas. Both grades are non-rusting with a brushed finish.
Q:What is the difference between an invisible cover and a normal cover?
A:
The invisible cover body has an open frame that accepts the same tiles or stones used on the pavement, so the finished surface sits flush with the ground and the cover is almost invisible.

A:
A15 for pedestrian areas, B125 for pedestrian zones with light vehicles, and C250 for parking and vehicle access, all tested according to EN 124.
Q:What sizes can you produce?

Q:What tile thickness can the cover accept?
A:
The seating depth is made to order from 20 to 80 mm, matched to the actual tile or stone thickness of your project.
