Prime alloy steel SMA400BW corrugated steel roofing sheet

BBN is a alloy steel SMA400BW world leader in exporting A106 / SA 106 pipe and stocks a full range of grades B/C with a size rage NPS 1/8" to NPS 48", with nominal (average) wall thickness as given in B36.10.

alloy steel SMA400BW, Wear-resistant steel plate has good corrosion resistance:
The alloy layer of the wear-resistant composite steel plate contains a high percentage of metallic chromium, so it has certain anti-rust and corrosion resistance. It can be used to prevent coal sticking when it is used in coal dropping drums and hoppers.

The carbon content of alloy steel SMA400BW, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
