Frequently Asked Questions (FAQ)
1. What material is the grating made of?
We use Q235 mild steel, a common structural carbon steel with good weldability and strength. The final product is hot-dip galvanized for corrosion protection.
2. Can the load capacity be increased for heavier applications?
Yes. By adjusting the bearing bar size (e.g., 50x5mm, 65x5mm) or reducing the spacing, we can achieve higher load ratings. Please consult our engineers for your specific requirements.
3. Is the galvanizing thickness sufficient for outdoor use?
Our standard hot-dip galvanizing provides a zinc coating thickness of at least 65μm (averaging 85μm), which offers excellent protection in most outdoor and industrial environments. For extreme conditions, a thicker coating is available upon request.
4. Do you offer custom sizes and shapes?
Absolutely. We can produce panels in various lengths, widths, and even cutouts for pipes or columns. We also offer non-standard bar spacings and special edge details. Just provide your drawings or specifications.
5. How long does delivery typically take?
For standard sizes, production usually takes 10–15 working days after order confirmation. Custom orders may require 15–25 working days depending on complexity. We ship from Tianjin or Qingdao ports.
6. Can I get a sample before placing a bulk order?
Yes, we provide free samples (only freight charges apply). We can send a small cut piece (e.g., 200x200mm) for quality evaluation. Contact our sales team to arrange.
7. What is the weight of a standard panel?
Weight depends on dimensions and spacing. For example, a 1,000mm x 3,000mm panel with 40x5mm bars at 50mm spacing weighs approximately 45–55 kg. We can provide exact weight upon request.
8. How do you pack the gratings for export?
We pack panels in steel crates or bundles, separated by wooden spacers to prevent scratches. For small quantities, we use plywood cases. All packaging is suitable for sea freight and easy handling.
