GRP Trench Covers

Relinea’s GRP Trench Covers (also known as access hatches) are a lightweight, cost-effective alternative to awkward and heavy steel or concrete covers. Our range of Composite trench covers which can be used in conjunction with our grp grating provides safe and secure access to pumps, cables and dry wells.

We can fabricate your GRP Trench Covers to suit any existing layout, saving you valuable installation time on site. Due to the lightweight nature of our trench covers, they can be fitted by just one or two men, avoiding heavy lifting or the need for extra equipment. The lightweight design of the covers allows for easy access when routine inspections and repairs need to be carried out.

As with all our GRP products, our trench covers are incredibly durable and resistant to corrosion. They have an excellent strength-to-weight ratio and a gritted anti-slip surface. The many advantages of our GRP covers such as the lightweight design, anti-slip surface, and non-conductive properties mean that they are widely used for a huge number of applications across numerous industries.  Trench Covers are commonly used in the Electricity sector (Duct Covers), Industrial sector (Walkways), Commercial sector (Gully Covers) and the Rail sector (Cable Protection Troughs).

All our trench covers come with the option of:

  • Spring assisted single person lift
  • Integral safety grid
  • Access ladders

Relinea’s GRP trench covers and access hatches conform to BS 124:1994 – Group A15.
