Long Service Life
1.Adopting the high-performance resin, glass fiber and special
formulation of process.
2.By above, the resin can be sufficiently dispensed in the glass
fiber strands, significantly enhance the bonding strength between
3.No internal damage for the material under the action of cycle
loading, consequently, the service life of the product is
guaranteed, normally, it will not less than 20 years under the
action of the Rated load and frequency.
Excellent Anti-corrosion Property
1.With rational structure design and high anti-corrosion material ,
2.Significantly keep the key parts from to be worn in practice,
3.So entirely, the application effect is better than that of
casting iron product.
Remarkable Anti-aging Property
1.Based on the property of the composite material and special
UV-proof assistant agent,
2.Has excellent property of Light Fastness and humidity proof,
3.Colour Fastness on the appearance is great than class 3 specified
in the standard of EN20102-A03:100
1.The product is made of thermosetting composite material,
2.No reinforced by steel, so no recycling value,
3.Thoroughly solve the stolen problem on the casting iron covers.
1.Excellent resistance to low&high temperature(can be used in
-50 to +1500C),
2.High resistance to chemicals(alkali, acid, salt and organic
3. A strong size stability( very low Hot Inflation Coefficient
1.Lightweight, less than 1/3 that of casting iron product, easy to
installation, inspection and daily maintenance.
2.Has the function of rebound proof and impact proof in the
structure, and eliminate the drawbacks which are difficult to be
overcome on the casting iron products.
3.Beautiful appearance, color can be opted for to be harmony with
environment, and beautify the city.
