FAQ

Q: What steel grades do you typically use for retaining wall posts, and can you supply mill test certificates?

A: We primarily utilize structural carbon and low-alloy steels such as Q355B, ASTM A36, and S355JR. Every shipment includes original Mill Test Certificates (MTC) verifying chemical composition and yield strength compliance.

Q: What is the standard thickness of your hot-dip galvanized coating?

A: Our hot-dip galvanizing process complies with ASTM A123 and EN ISO 1461 standards. For structural steel components exceeding 6 mm in thickness, the average coating thickness exceeds 85 um to 100 um, ensuring long-term corrosion resistance in aggressive soils.

Q: Can you manufacture posts with custom base plates, pre-welded cleats, and slotted holes?

A: Yes. We operate as an OEM structural steel fabricator. We cut, drill, punch, and weld base plates, stiffener gussets, connection cleats, and slotted bolt holes precisely according to your engineering drawings.

Q: What is your standard production lead time for bulk container orders?

A: Standard production lead time ranges from 25 to 35 days, depending on raw material availability, total tonnage, and galvanizing schedule requirements. Expedited processing can be coordinated for urgent project milestones.

Q: How do you prevent "white rust" (zinc wet storage stain) during ocean transport?

A: We ensure components are completely dry and cooled prior to bundling. For long-haul maritime shipping, we apply breathable spacers between steel sections and can add protective wrapping upon request to prevent moisture condensation trapping.

Q: What welding standards and qualifications do your production facilities adhere to?

A: Our welding operations follow standard structural fabrication guidelines, utilizing AWS D1.1-compliant welding procedures. Welders are certified for structural carbon steel applications, ensuring consistent fusion and mechanical load resistance.

Q: What file formats are required to get an accurate quote for custom retaining wall posts?

A: We accept 2D drawings in PDF or DWG/DXF formats and 3D models in STEP or IGES formats. Clear dimensional callouts, steel grade specifications, and coating requirements enable a rapid and precise cost estimation.

Q: What is your Minimum Order Quantity (MOQ) for custom fabricated steel posts?

A: Our typical MOQ is structured around batch production efficiency, generally starting from 2 to 3 metric tons per profile size or specific project run. Mixed-size container loads can be accommodated for comprehensive engineering packages.
