Our steel pipes include four major types which are seamless pipe, ERW pipe, LSAW pipe, SSAW pipe, grade P235GH steel standard. Seamless pipe supply scope is OD 10.3mm--965.2mm, wall thickness 1.0mm--60mm. The ERW pipes production range from OD 21.3mm--660mm, wall thickness 1.0mm--16mm. LSAW pipes can supply with OD 406mm--1524mm, wall thickness 6mm--50mm. SSAW pipes can produce maximum OD 3500mm, minimum OD 219.1mm, wall thickness 3.2--25.4mm.

40B steel plate is alloy structural steel plate formed by adding boron to the carbon structural steel with a carbon content of 0.40%. grade p235gh steel standard, 40B steel plate has high hardness, toughness and hardenability, and has good comprehensive mechanical properties after quenching and tempering, which can be used instead of 40Cr steel. 40B steel plate chemical elements: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.60-0.90, B: 0.0005-0.0035. 40B steel plate is used to manufacture parts with larger section and higher performance requirements.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized grade p235gh steel standard are higher than that of annealed grade p235gh steel standard, but the elimination of internal stress is not as good as annealing. The normalizing operation of grade p235gh steel standard is simple, the cost is low, the productivity is high, and it is widely used in actual production.

We have a professional production team and high-quality production equipment, and we also have a great grade p235gh steel standard advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the grade p235gh steel standard production of high-quality steel plates, steel pipes and other products that meet customer requirements.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality grade p235gh steel standard products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
