A manhole cover is an unfixed, detachable lid with a fitted frame that covers an open hole in the ground, usually used to access underground pipes or vaults. Choosing the right manhole cover can be a bit of a challenge as there are so many outstanding ones in the market. This is why you need to take your time selecting the right manhole cover.
Selecting an ideal manhole cover that fits your needs and requirements
can be a long process. However, the main thing you need to consider before you
invest in any manhole cover is as follows:
The
Type of Material
Before you choose a manhole cover to purchase, you need to take a
thorough look at the material it is constructed from. Manhole covers are
usually made from galvanized steel, stainless steel, cast iron, aluminum, or
polypropylene.
Galvanised Steel Manhole Covers
Galvanized steel manhole covers are coated with a thin layer of the
element zinc which offers protection against rust, which results from exposure
to water and oxygen. These covers are ductile and are easily maintainable due
to their strength. Galvanized steel manhole covers are also significantly
cheaper than stainless steel ones.
Stainless Steel Manhole Covers
Stainless steel manhole covers, on the other hand, are made with iron,
chromium, and carbon. These provide a substantial amount of corrosion
resistance. Stainless steel manhole covers are noticeably costlier than
galvanized steel ones due to their time-consuming manufacturing process.
Aluminum Manhole Covers
Aluminum manhole covers are constructed to be lightweight and durable.
These covers tend to be high-quality ones and are known to feature an
aesthetic, extruded construction. Aluminum manhole covers are also cheaper
than stainless steel ones, so they can often be the better option.
Ductile Iron Manhole Covers
Ductile iron is an alloy constructed from graphite shaped like nodules.
True to their name, ductile iron manhole covers are incredibly ductile and
resistant to breaks and bends. Although these manhole covers can handle lower
temperatures than cast iron ones, they still remain exceptionally durable and
resilient.
Cast Iron Manhole Covers
Cast iron is another iron alloy made from iron, carbon, and silicone. These manhole covers are known to be highly temperature resistant. They are significantly stronger than other manhole covers and can handle vibrations from the ground extremely well.
