Kev sib piv nrog ASTM A500 (feem ntau siv)
- A501:Kub-rolled forming, looser muaj pes tsawg leeg yuav tsum tau, tsawg zog qib (A/B/C), tus nqi qis, haum rau cov qauv.
- A500:Txias-tsim, nruj tswj cov khoom siv kho tshuab, qib zog ntau (A/B/C/D), zoo formability, haum rau precision / siab-xav tau qauv.
Tus neeg thov Field:
- Cov Khoom Siv Hauv Tsev:Factory vaj tse, siab-cov tsev nce siab, txuas hniav, trusses, kab thiab kab teeb, kev txhawb nqa.
- Machinery thiab khoom siv:Conveyor thav duab, steel qauv platforms, tsheb chassis, siv tshuab.
- Piping thiab Engineering:Kev thauj mus los ntawm cov kua dej dav dav, kev tsim vaj tsev hauv nroog, tsis yog - siab - cov kav dej muaj zog.
- Lwm tus:Shelving, guardrails, steel structural Cheebtsam, welded / riveted / bolted kev twb kev txuas lug.
