Q1: How to get to your factory?
You can fly to Hangzhou Xiaoshan International Airport, and we will meet you there. If there’s no flight available, you can arrive at Shanghai (Hongqiao or Pudong) and we will pick you up.
Q2: What is your production time?
Typical production lead time is 15–30 working days after order confirmation and deposit. The final lead time depends on product type, quantity, customization and production schedule.
Q3: What is the delivery date?
It depends on your order quantity, and can be negotiated.
Q1: What are the standard full sizes of FRP grating?
The standard full sizes are 1.22×2.44m, 1.22×3.66m and 1×4m.
Q2: Can the size of FRP grating be customized?
Customization is available within the range of standard full sizes. For sizes exceeding the standard range, the grating needs to be split into multiple pieces.
Q3: Is it easy to cut FRP grating on my own?
Yes, it is easy. Mark the required size and cut the grating with an angle grinder. Note that different cutting methods will result in different material losses.
Q4: Are all customized FRP gratings with edge trimming?
Standard full-size gratings come with full edge trimming. For customized sizes, edge trimming is not universal and includes three-side trimming, opposite-side trimming and adjacent-side trimming. If the customized size is exactly cut to the hole position, there will be no edge trimming. You can consult our customer service for the nearest edge-trimmed size or opt for edge sealing (edge sealing is charged separately per meter).
Q5: Are FRP grating panels and FRP grating covers the same?
No, they are not the same. FRP grating panels are perforated and water-permeable, while FRP grating covers are sealed with patterned plates on the surface. Please specify your required type clearly.
Q6: What is the standard thickness of FRP grating covers?
The standard thickness of most grating covers is 1mm, and thickening is available upon request.
Q7: What are the common thicknesses and corresponding specifications of FRP grating?
Common specifications are as follows:
- 25mm thickness: 38×38×25mm, 25×50×25mm, 25×38×19mm (main grid: 38×38mm)
- 30mm thickness: 38×38×30mm
- Corresponding standard sizes: 1.22×3.66m, 1.22×4.04m, 1×4.04m
Q8:What are the complete model ranges of FRP grating?
The grating models include:
- 25mm series: 25×38×38, 25×40×40, 25×43×43, 25×50×25, 25×38×19
- 30mm series: 30×38×38, 30×40×40, 30×50×25
- 38mm series: 38×38×38, 38×40×40, 38×38×19
- 50mm series: 50×50×50, 50×40×40, 50×38×38, 50×100×100
- 65mm series: 65×52×52
Q9: What are the national and non-national standards for the rib width of FRP grating?
For national standard grating: the upper rib width is 7mm and the lower is 5mm. For non-national standard grating: the upper rib width is 6mm and the lower is 4.5mm. A slight upper and lower deviation is normal for molded grating during demolding.
Q10: What are the main components of FRP grating?
FRP grating is primarily manufactured from continuous glass fiber reinforcement, a thermosetting resin system, pigments and selected functional additives. Resin type and formulation are selected according to corrosion resistance, flame-retardant, UV and project requirements.
Q11: Are there different resin types for FRP grating, and when to choose a specific type?
There are various resin types available (e.g., 196 resin, 3301 resin, 901 resin). Please inform us in advance if you have special requirements such as acid and alkali resistance, corrosion resistance and high temperature resistance, and we will select the appropriate resin type for you.
Q12: Why do some FRP gratings have small cracks on the surface?
Minor surface variations may occur due to the molding process, but they must not affect structural integrity or intended performance. Each panel undergoes visual and dimensional inspection before shipment. Products with structural cracks, exposed reinforcement or unacceptable defects will not be released.
Q13: What are the characteristics of the front and back of FRP grating?
The front of FRP grating is smooth and flat. The back has fiber filaments, which is not as aesthetically pleasing as the front (similar to the bottom of a car), but the product is still economical and durable.
Q1: What are the available payment terms?
We generally accept T/T and L/C at sight. Payment terms may vary depending on the order value, product type and customization requirements. Please contact our sales team for confirmation before placing an order.
Q2: How long is the warranty period?
We provide a three-year limited product warranty, subject to the agreed specifications, installation conditions and operating environment. Expected service life is separate from the warranty period and depends on resin type, load, UV exposure, chemical environment and maintenance conditions.
