Frequently Asked Questions (FAQ)
-
Q: Is the 304 stainless steel suitable for outdoor use?
A: Yes, 304 stainless steel offers excellent resistance to atmospheric corrosion, making it ideal for outdoor drainage applications. However, for coastal or highly corrosive environments, we recommend 316L grade as an option. -
Q: Can the clear opening be customized to other sizes?
A: Absolutely. We can adjust the clear opening from 10mm to 50mm or more based on your drainage requirements. Please provide your specific needs. -
Q: What is the load capacity of this grating?
A: The load capacity depends on bar thickness, spacing, and overall dimensions. For standard configurations, it can support up to 5 kN/m². We can engineer higher capacities for heavy-duty applications. -
Q: How is the grating fixed to the steel floor?
A: Common methods include welding to support beams, using clips, or bolting. We can supply matching accessories or provide installation guidance. -
Q: Do you offer pre-cut panels or custom shapes?
A: Yes, we can cut panels to exact dimensions, including notches, angles, or curves, to fit your floor layout. -
Q: What surface treatments are available?
A: Standard is mill finish. We also offer pickling and passivation to remove welding heat tint and enhance corrosion resistance. Other treatments like electro-polishing are available upon request. -
Q: Is there a minimum order quantity?
A: We typically require a minimum order of 10 square meters for standard sizes, but we can discuss smaller quantities for sample or prototype needs. -
Q: How long does shipping take?
A: For most international orders, sea freight takes 20-35 days depending on destination. We can also arrange air freight for urgent projects.
