The Ultimate Guide to Choosing Load-Rated Manhole Covers and Drainage Systems
When it comes to selecting the right manhole covers, channel drainage systems, storm drains, or gully grates, understanding load ratings is crucial. The load rating serves as proof that a product has been tested and certified to withstand specific weight loads. This vital information allows you to make an informed decision before purchasing.
Let's take a closer look at load classes and their significance:

B125 Class: Designed to handle a maximum load of 12.5 tonnes, the B125 class is ideal for domestic driveways where larger vehicles like 4x4s or vans may be parked.
C250 Class: This class can handle a maximum load of 25 tonnes. It is commonly used in lightly trafficked roads and private car parks.
D400 Class: With a load rating of 40 tonnes, the D400 class is suitable for high-traffic areas like main roads, highways, and public car parks.
E600 Class: If you're looking for a robust option, the E600 class with a load rating of 60 tonnes is ideal for industrial estates, cargo handling yards, and delivery depots.
F900 Class: The F900 class is the most heavy-duty option with a maximum load rating of 90 tonnes. It is reserved for extreme applications such as airports and docks.
