Heavy Duty Covers and Frames

When it comes to finding suitable products for your intended application, you needn’t look any further than Build Plumb Plastics! We supply heavy duty manhole covers to suit the requirements of all customers, so don’t hesitate to check out our extensive range of products below.

Heavy duty manhole covers are simply removable plates that form a lid over the manhole. The main purpose of the heavy duty manhole covers is to restrict unauthorised access and to prevent anything falling in the manhole. Typically, a manhole cover will be found on driveways or pavements to prevent any dangers.

The heavy duty manhole covers that we provide at Build Plumb Plastics are designed to suit any areas of heavy or regular traffic and each complies with British Standards. Our products are designed and manufactured in the UK and include reputable brands like Clark Drain.

We supply the heavy duty manhole frames too; these are suitable for various loading capacities and protect manholes. Within our collection of heavy duty covers and frames, you’ll discover the manhole chamber reducer ring, amongst many other products. The reducer ring is made from black polypropylene and reduces the opening of the manhole- it’s also ideal for new and existing installations. 

The heavy duty manhole covers are hinged, making it easier to lift the plate for inspection. Here at Build Plumb Plastics, we supply the lifting keys for medium and heavy duty manhole covers, allowing you to lift the lid with ease and to carry out regular servicing and maintenance.

Any heavy duty manhole frames and covers are prone to several impacts; therefore, they need to be able to withstand these, without compromising safety standards. Our heavy duty manhole frames and covers incorporate an anti-slip tread meaning that they are safe to use (which is ideal if they are placed on pavements.)

Here at Build Plumb Plastics, we also supply the Clark Drain CLKS1657 heavy duty manhole cover and frame which is made from cast iron. Grey in colour, with a black polypropylene frame, this heavy duty manhole cover is perfect for pedestrianised areas and is compatible with many other accessories.

When choosing heavy duty manhole covers or heavy duty manhole frames, you need to make sure that you choose the right one. To avoid choosing the wrong size covers and frames, take into consideration the exact requirements of the manhole. By choosing the right size products, you’ll get more out of them.

If you need any assistance choosing the size of your heavy duty manhole frames or covers, be sure to discuss your requirements in detail with the team here at Build Plumb Plastics! We aim to accommodate the needs and wants of all customers, providing them with suitable products for their specific application.
