Q355NH steel plates and sheets with atmospheric corrosion resistance are mainly used for vehicles, bridges, containers, buildings, towers, and other structures. Weather-resistant steel can be used to make bolted, riveted and welded structural parts. We can also slit and sheet Q355NH (Equivalent A588 steel) to any weight and size for immediate delivery. Our A588 Grade A structural steel plate, Q355NH weathering steel plates are produced with thickness up to 100mm.
The impression of most customers who have cooperated with us on the company is being professional and responsible. That mainly owe to our united and considerate team members. For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.
We have 4 typical production lines A588 Grade A structural steel plate, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.
The work performance of A588 Grade A structural steel plate etc. steel material is mainly depended on its chemical composition, mechanical properties etc. parameters. The higher strength the steel has, the less quantity steel is needed to achieve same strong effect of the steel structure. However, the steel strength varies with the thickness. So please take steel thickness into consideration when evaluating the steel strength. For a certain steel, its strength also has something to do with the steel shape. For example, for a same steel grade, the steel strength is different for steel plates and pipes.
