Welcome to BBN High Strength Steels Factory
After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, S690QL plate specification tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of S690QL plate specification steel and 542,000 tons of steel.
After comprehensive and professional training such as customer service, the customer service team has more strict discipline in the management of customer service team to ensure that customer service personnel respond to customers with a professional attitude. A process supervision system has been set up to let each customer supervise the process of the system with us
Steel plates for oil and gas pipelines: X42 (L290), X46 (L320), X52 (L360), X56 (L390), X60 (L415), X65 (L450), X70 (L485), X80. Executive standard: API -5LB (L245). Main purpose: used to make oil and natural gas pipelines. API 5L generally refers to the pipeline steel plate-API 5L pipeline steel plate. The pipeline steel plate is processed into large-diameter pipeline steel pipe to transport the oil, gas, and water extracted from the ground through the pipeline pipe to the oil and natural gas industrial enterprises.

[200mm], min %: 18; Elongation in 2 in. [50mm], min, %: 22
In December of 2015, our regular India customer sent us an inquiry for S690QL plate specification pipe. The inquiry requires no negative tolerance in both pipes’ outer diameter and pipe wall. After two weeks’ discussion, he put the order of 275 tons to us. The pipes are finished within just one month. Our customer come to our factory to inspect the quality and tolerance, all the products are well meet his demand. The pipes are arriving to Nhava Sheva port, customer is very happy with our products and service during the process.
Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled S690QL plate specification plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive S690QL plate specification industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
