Clear opening size or external dimensions? Cast iron or steel? Seal or no seal? Here’s how to choose the right cover for your project.
Manhole and access covers are manufactured in various shapes, sizes and materials to suit every need. The importance of choosing the right one cannot be understated, as choosing an unsuitable cover for your application can have significant safety and security implications. Deciding which cover is right for you can seem like a daunting task… but it doesn’t have to be!
The key is in understanding your application and being able to answer the following questions:
- What size do I need?
- What weight loading should it be?
- What type of cover do I want?
- What type of seal should it have?
As you go through this list the choice of cover may be determined for you. For example, if you’re looking for a cover in a highway, you can only use cast/ductile iron BS EN 124 covers instead of a steel cover.
We’ve put together the following information where we’ll cover (pun intended) the most common options available and offer advice how best to answer these questions.
