A15 Series Square SMC Manhole Covers

Advantages of SMC/fiberglass manhole covers:

(1) SMC manhole covers have smooth and beautiful appearance, anti-skid design on cover surface, colors and patterns can be desiged according to specific needs.

(2) The SMC manhole covers are much lighter in weight, about one third of the similar products of cast iron and cement.

(3) With good toughness and are not easy to crack, the load ability can be designed to meet A15/b125/C250/D400/E600/F900 according to BS EN 124-1:2015, EN 124-5:2015.

(4) The composite manhole covers are tightly combined and balanced without warping, bouncing or other deformation phenomena. Cast iron manhole covers are not closely combined, easy to jump when the vehicle is running and with high noise.

(5) The composite manhole covers are characterized by corrosion resistance, coloration and good sealing, etc., which are easy to identify and daily maintenance, effectively reducing the labor cost of maintenance and the expense of renewal.
