After several months of efforts, our company’s R & D working people updated our production technology for our FRP manhole covers products. The weight of our manhole covers,keeping same load ability, should be reduced by 10%.This can greatly reduce the cost of transportation for our customers,and directly increase market competitiveness.
For example, 650mm Round Manhole Cover (D400) is of weight 70 kgs each set. A 20′ container could load 315 sets of covers.
After technology updates, product weight becomes 64 kgs/set. Now,a 20ft container can hold 345 units. Customers could save the shipping fee for 30 sets FRP manhole covers.
