Long Service Life
• Adopting the high-performance resin, glass fiber and special formulation of process.
• By above, the resin can be sufficiently dispensed in the glass fiber strands, significantly enhance the bonding strength between them.
• 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
• With rational structure design and high anti-corrosion material ,
• Significantly keep the key parts from to be worn in practice,
• So entirely, the application effect is better than that of casting iron product.
Remarkable Anti-aging Property
• The property of the composite material and special UV-proof assistant agent,
• Has excellent property of Light Fastness and humidity proof,
• Colour Fastness on the appearance is great than class 3 specified in the standard of EN20102-A03:100
Anti-theft Property
• The product is made of thermosetting composite material,
• No reinforced by steel, so no recycling value,
• Thoroughly solve the stolen problem on the casting iron covers.
Comprehensive Property
Excellent resistance to low&high temperature(can be used in -50 to +1500C),
     2.High resistance to chemicals(alkali, acid, salt and organic solution agent),
    3. A strong size stability( very low Hot Inflation Coefficient 12*10-6/0C)
