We are the sole factory in China, which can provide you with real Grp/FRP manhole covers with patented technology. After you get our free sample, you need to make load ability test according to EN124. The traditional BMC manhole covers couldn’t pass the test of EN124. If you need the test video for load ability, you can contact us to get more details by our email address ‘info [at]’.

Attention: Many customers sent us the drawing of ductile iron manhole covers and asked us to produce the same. We need to clarify the fact here that we can’t produce the completely same as the drawing of ductile iron manhole covers because we use composite materials. We could produce any covers sizes or clear opening sizes for our composite manhole covers according to your requirements, but we can’t keep other parts sizes(cover thickness, etc) of manhole covers same as your drawing of cast iron covers.
