Product introduction

Standard specification for high strength low-aly structural chalybs, usque ad 50 ksi [345 MPa] punctum minimum cedit, cum resistentia corrosionis atmosphaerica.
Requisitus ASTM G101 Corrosionis Resistentiae Index debet esse ≥ 6.0. Praeter applicationem typicam in pontibus et aedificiis iuncta, specificatio etiam communiter in autocinetis railis adhibetur.

Specificationes:
Crassitudo: 3mm--150mm
Latitudo: 30mm--4000mm
Longitudo: 1000mm--12000mm
Standard: ASTM EN10025 JIS GB
