Frequently Asked Questions

Q: What is the difference between pressure welded and locked grating?

Pressure welded grating uses heat and pressure to fuse the bars, offering higher rigidity and a cleaner finish, while locked grating uses mechanical interlocking for specific structural requirements.

Q: Why is Hot Dip Galvanizing (HDG) preferred over painting?

HDG creates a metallurgical bond with the steel, providing a thicker, more durable coating that protects against rust and abrasion far better than surface paint.

Q: How do I choose the correct bearing bar pitch?

Pitch depends on the load capacity and safety needs. We generally recommend 30mm or 40mm for a balance of strength, drainage, and foot traffic safety.

Q: Is serrated surface grating safer than plain surface?

Yes, serrated surfaces provide significantly higher grip, making them ideal for areas exposed to oil, water, or ice to prevent slips and falls.

Q: What is the minimum order quantity (MOQ) for custom specifications?

Our minimum trial order is typically 25 tons per thickness, delivered in a 20-foot container to ensure production efficiency and shipping cost-effectiveness.

Q: Can you provide different packing options for international shipping?

Yes, we offer LCL packing with plastic film and pallets, FCL nude packing for maximum volume, and various other special packages based on your specific requirements.
