High flame resistant vinyl ester
| Superior corrosion resistance and enhanced fore retardant flame spread rating ASTM E84 Class 1,10 or less operation temperature-50°C~110°C.Such grating has passed assessment from ABS(American Bureau of Shipping).
| Such gratings can be used in the environments with serious corrosion requiring better flame resistance.
|
Iso-phthalic Polyester resin
| Industrial grade corrosion resistance and fire retardant flame spread rating ASTM E84 Class 1,25 or less operation temperature-50°C~105°C.
| Such gratings can be used in the environments of middle concentration inorganic acid, inorganic alkali, etc.
|
Ortho-phthalic polyester resin
| Moderate corrosion resistance and fire retanrdant flame spread rating ASTM E84 Class 1,25 or less operation temperature50°C-100°C.
| Such gratings are perfect for use in water/wastewater or air-aging application light industrial applications and in the wave zone areas of offshore platforms where the environment is moderate Although Type O is the least chemical resistant resin it still offers superior performance to traditional flooring products such as steel aluminum and wood and is the most economical resin available. |

FAQ(Frequently Asked Questions):
Q: Are you a trading company or a manufacturer?
A: We are a manufacture as you can see our workshops' photos herein.
Q: What is your payment term?
A: T/T, L/C, paypal, etc can be accepted.
Q: Can I place sample order first?
A: Yes, we can provide sample first for your check.
Q:What kind of trade terms can you do?
A: FOB, CIF, CFR, etc can be accpetd.
Q: What features should I consider when choosing FRP gratings?
A: You should consider your specific application in regards to environment, span, open area, impact resistance and layout utilization.
Q: Why is molded grating more corrosion resistant than pultruded grating of the same resin type?
A: Resin protects the glass fibers from corrosive chemicals. Molded grating has 65% - 70% resin whereas pultruded grating has only 30 - 35% resin. Secondly, molded grating is one-piece homogeneous construction whereas pultruded grating is assembled into panels. The corrosion barrier of the pultruded pieces are compromised when holes are drilled into components for panel assembly.
Q: What is the leading time for the samples?
A: Normally 7 to 10 working days.
Q: What is the leading time for bulk order?
A: Normally 30 to 40 working days.
Q: Do you have the MOQ for the products?
A: No, we do not have any MOQ, 1pcs, 1 square meters is available for us.
Q: Do you have detailed and professional installation manuals?
A: Yes, we have. And we shall provide along with the shipping.
