5.FAQ:

Q. I have a heavy traffic manhole cover but it has been broken by a forklift, why?

A. Forklifts have solid wheels which apply pressure differently to standard pneumatics and therefore covers must be specially adapted to suit this.

Q. I’ve measured my clear opening size but none of your covers match it, can you offer anything?

A. It’s likely that your cover is quite old and in imperial measurements which are no longer manufactured. However, we can offer bespoke solutions with manhole covers made to the specification you require.

Q. The project I’m working on requires a manhole cover with a quality finish, what’s available?

A. Naturally, galvanised steel of black polypropylene aren’t always ideal, and so we offer brass or stainless steel edging, as well as complete stainless steel covers.

Q. Odours are coming through where I have installed my manhole cover, why?

A. Your cover must be sealed and locked, or neoprene sealed, so you would require a T-Range Cover, or if you require a solid top, a selection of the PC range (e.g. PC2BG3, PC6CG3, not PC2BG) are suitable.
