2022 High Quality Fiberglass Molded Grating - frp molded grating – WellGrid
2022 High Quality Fiberglass Molded Grating - frp molded grating – WellGrid Detail:
Advantages
1. Corrosion Resistance
Different types of resin provide their own different anti-corrosion properties, which could be used in different corrosion circumstance such as acid, alkali, salt, organic solvent (in gas or liquid form) and the like over a long period.
2. Fire Resistance
Our special formula provide grating with excellent fire resistant performance. Our FRP gratings pass ASTM E-84 Class 1.
3. Light Weight & High Strength
The perfect combination of the continuous E-glass roving and thermosetting polyester resin provide grating with light weight and high strength and its specific gravity is only 1/4 of that of steel, 1/3 of aluminum. Its rigidity is up to and even exceeds that of steel. Different thickness and mesh size bring the client more choice.
4. Safety & Anti-slip
The high modulus of elasticity and various surfaces provided the super anti-skid performances. Its surface could be smooth surface, meniscus surface, grit surface and chequer plate cover which is suitable for different working places.
5. Electrical Insulating
High strength E-glass roving and high-grade resin provide the product super electric performance. Its electric break strength could reach 10KV/mm. There is no electric spark even when impact by tools, meanwhile it is non-magnetism. FRP Molded Grating could be used safely under the antiknock, diamagnetism and electric-resistance environments.
6. Aging Resistance
The high-grade resin and anti-ageing stabilizer provide grating long-life ageing resistant performance and the unique design make grating excellent self-cleanness function and keep its brightness and strength over a long time. The service life of grating could be 25 years.
