Frequently Asked Questions (FAQ)
-
Q: What is the load capacity of this grating with 50x5mm bars and 100mm spacing?
A: The load capacity depends on the span and application. Typically, this configuration can support pedestrian loads (approx. 4-5 kN/m²) and light vehicular traffic. For specific load ratings, please provide your span and desired safety factor, and we will provide a detailed calculation. -
Q: Is the ASTM A123 coating suitable for outdoor use in coastal areas?
A: Yes, hot dip galvanizing per ASTM A123 provides excellent corrosion resistance in outdoor environments, including coastal areas. However, for extreme marine or chemical exposure, additional coatings or stainless steel options may be recommended. We can advise based on your environment. -
Q: Can you customize the panel dimensions (length and width)?
A: Absolutely! Our standard panels are up to 1250mm wide and 6000mm long, but we can cut or fabricate to your exact dimensions. Please provide your required sizes for a quotation. -
Q: What is the typical lead time for this product?
A: For standard sizes, lead time is approximately 15-25 working days after order confirmation. Custom orders may require 20-30 working days. Rush orders are available upon request. -
Q: Do you provide serrated (anti-slip) surface options?
A: Yes, we can supply serrated bearing bars for improved slip resistance. This is a common requirement for wet or oily work areas. Please specify when ordering. -
Q: What kind of edge treatment do you offer? Can we have banding or toe plates?
A: We offer various edge options: cut band, square cut, or with bent tabs. Toe plates, banding, and other custom edge treatments are available. Share your drawing or requirement for a solution. -
Q: Is the grating certified by any third-party testing organization?
A: Our product complies with ASTM A123 standards. We can provide mill test reports (MTR) for material traceability and coating thickness certificates. No third-party certification is currently maintained, but we can arrange for inspection by your designated agency at an additional cost. -
Q: How is the grating packed for export?
A: Panels are bundled with steel straps, protected by edge guards, and wrapped with waterproof paper or plastic for container shipping. Each bundle is clearly labeled with dimensions and quantity. We ensure safe delivery to any international port.
