| Certification | ISO 9001, CE Marking, Mill Test Certificate (MTC) | Third-party inspection available; certificates per EN 10204 Type 3.1 upon request |
| Packaging | Bundled in 2–5 MT bundles with steel wire binding | Bundles tagged with heat number, grade, and standard; seaworthy packing available for export |
| MOQ | 25 MT per size/grade | Mixed container orders accepted; bulk shipment available for large construction projects |
Initial shipment had surface rust on outer bundles — issue resolved satisfactorily
Our first order of 180 MT of ASTM A615 Grade 60 #5 and #8 bars arrived with moderate surface rust on the outermost bundles, likely from extended port storage during transit delays. We raised the issue immediately. The supplier's QC team reviewed our photos within 12 hours, confirmed the rust was superficial and within ASTM permissible limits, and provided a written technical clarification for our project engineer. They also arranged additional protective wrapping at no cost for our follow-up order. The rebar itself tested fine — yield 431 MPa, elongation 10.1%. Issue handled professionally; will reorder with improved packaging agreed.
