FAQ: 

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, EXW, etc can be accpetd. 
Q: How to get to your factory?      
A: In nantong, we have Xindong Airport. If there is flight, you can first come to Xindong Airport, and then we shall go there and accept you. If there is not flight,  it is possible to go to Shanghai Airport (Hongqiao, Pudong are both okay), and then we shall pick up you there. 
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.
