Additional Information on Manhole Covers

There are several different types of manhole cover and frame products for a range of applications, from plastic, cast iron, galvanised steel or composite products all at different prices. Feel free to search through our categories in which the manhole covers have been sorted to make finding the correct manhole covers, tools or products easy for you.

Manhole cover and frame products are a valuable construction element that provides several functions for many applications. Usually fitted onto an inspection chamber, the products enable maintenance workers to gain access to telecom lines and underground drain pipes or an inspection chamber. Additionally, they serve as access points for meters that quantify the flow of liquid in the effluent pipes.

Manholes have to be covered using manhole covers to shield anything or anybody from falling in the manholes, inspection chamber or drain and keeping out unwanted materials and unauthorised persons out of the inspection chamber.

Tips Before Buying:

Over the years the cover will wear out, they become weak because of exposure to the elements. The products eventually break, especially if they’re made of plastic or steel.

Broken drain covers allow drain odours to leak from drainage systems and are risky for vehicles and pedestrians, so the products must be replaced.

Here are the key factors to consider when buying replacement drain covers:

  1. Size

All manhole cover manufacturers use a similar technique to measure their covers: They are classified by their clear opening size, which is the size of the opening that they’re made to conceal.

  1. Loading Capacity

For security reasons, it’s imperative that the replacement manhole cover is fit for the purpose and loading capacity required, and this boils down to the areas that the drain covers are to be fitted, and the traffic in the area.

  1. Plastic, Ductile Iron or Steel?

As long as you stick to the guidelines as mentioned above, the decision is yours. Traditionally most manhole covers were made from ductile iron, but with modern-day advanced technology, the options are unlimited, and offer similar loading performance.

Galvanised steel manhole covers are easily installed and lightweight but can be rated up to 17 tonnes, so they are very versatile. On the flip side, cast iron and plastic manhole cover and frames are dark in colour, so they’re perfect drain covers for tarmacked driveways. Once you find out the correct weight loading capacity and size the choice is yours! Plastic or galvanised steel manhole lids are usually the cheapest option.

  1. Plastic Inspection Chambers, Drain Covers and Access Covers

For those who own new properties, there is a high probability that the manhole cover might be on top of plastic inspection chambers as opposed to brick manholes.

In such instances the width of the chambers must be measured, placing a tape measure across the inside – it’ll most likely be round. Then all that is required is to search for and buy manhole covers and frames to suit the size of the manhole chambers (usually 450mm).

Another thing to keep in mind is that you still have to ensure your drain cover is of the correct weight class when mounted on a plastic chamber!

  1. Block Paving and Patios

A Recessed manhole cover is just a metal tray that lets you lay out a slab or block paving inside to match the surrounding area. Usually made from galvanised steel recessed manhole covers are also available in different loads and sizes, so if you’re having your driveway block paved, replace your cover around the same time - just ensure that your recessed drain cover is of the right weight class.

  1. Installation Tips and Hints

Once the correct drain cover and frame and material have been sourced a builder, drain installer or other capable person should install the drain covers. The drain covers and frame should be bedded in concrete and levelled correctly. The concrete should be allowed to cure for at least three days before any weight is put on to the drain covers and frame.

FAQs:

Can a square cover be fitted into a circular chamber?

Yes, there’re a few covers that are round to square, meaning they’ll fit in round or square chambers. These covers include the 300SR, and the T1G3, to name a few.

Why did a forklift break my heavy-duty manhole lid?

Well, a forklift has rock-hard wheels, which exert pressure differently to typical pneumatic, so your cover frame must be specifically designed to suit this.

How do I know which size I need?

All sizes are measured by the clear openings inside the frames, as this is the only true constant between manufacturers’ designs.

I have the correct measurements of my clear opening size, but I can’t find a match, why?

This is because your manhole cover is old-fashioned and in imperial measurements. However, we can provide custom-made solutions with covers made to the exact specs you need, including the correct load rating.

Can you give me any pointers on the installation process?

I need access through my manhole covers regularly, is this possible?

Of course, most covers have inbuilt lift keys. However, the best way to get easy access is to order custom-made, hinged covers. Which is one of the services we can offer.

How does an access cover differ from a recessed cover?

Since they’re very similar products, most folks find themselves wondering what the difference is. Well, each has its own unique advantages and can be used for a range of different purposes.

Manhole covers are generally used to securely and safely hide the entrance of drains and other chambers. They're often made from concrete, galvanised steel manhole covers, ductile iron or cast iron or even a combination of several of other materials.

On the flip side, access covers are usually found on internal floors, driveways, car parks, foot ways, pavements, and roads. Their purpose is to protect pedestrians from falling in man-made holes and providing workers with access to below ground services.

Why are manhole covers circular?

Some possible explanations include:

  • A Circular cover doesn’t have to be rotated or precisely aligned when placing it on the opening.
  • A Round casting is much easier to make using a lathe.
  • It’s easier to dig circular holes.
  • Round covers can be easily rolled or moved.
  • Unlike square covers, round covers cannot fall through the circular openings, whereas square covers could fall in if they were installed diagonally.

Is anti modern slavery part of your policy terms conditions?

What is damp proofing?
