6.The Superiority Compared with Iron Casting Manhole Cover

g.Corrosion Resistance: The product is obvious acid and base resistance and corrosion resistance, with anti-aging index of over level 3 and long service life, through test by State Chemical Building Material Testing Center.

f.High Precision: Owing to high temperature compression molding, there is only small gap between the cover and seat, which overcomes the run, jump and sound problems of casting, cement etc. manhole covers and raises the road traffic capacity and traveling comfort level 

e.Strong Weather Resistance: The product can be used under-50+150 because it is made from high molecular synthetic material of big molecular weight and strong chemical stability with scientific recipe ,advanced process and perfect technical equipment.

d.Antitheft Feature: the synthetic material has no recovery value with natural antitheft feature the cover has locking structure and can prevent the property in the cover from theft, thus thoroughly stop the occurrence of the city black hole incident.

c.Light Weight: Its weight is only 1/3 of the same spec. of products, so it is suitable for transportation, installation and rush repair , which reduce the labor strength greatly.

b.Beautiful Appearance: The manhole cover has exquisite surface figure design and can be made into all kinds of colors to beauty the environment of city. 

a. High Strength: Made from high molecular synthetic material, mated with steel reinforcement cage, and compression molded by high temperature, with the top testing result of over 50 tons, which accords with and exceeds the newest standard CJ/T211-2005 issued by the Ministry of Construction of the Peoples Republic of China.
