The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy BP440 steel used for safety gate products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of BP440 steel used for safety gate stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.
BBN company is a modern enterprise integrating steel producing, warehousing and logistics, processing and distribution. We are committed to creating a "one-stop steel procurement service" platform. The main products are I-beam, angle steel, BP440 steel used for safety gate , H-beam, hot-rolled coil, welded pipe, spiral pipe seamless pipe and many other steel products. Standing stocks amount to more than 30,000 tons, and complete specifications, the company gradually moves towards large-scale distribution enterprises with serialized products, standardized services and modern transportation management.
Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled BP440 steel used for safety gate products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the BP440 steel used for safety gate rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
The Seamless Pipe Q345D to Thailand. In November of 2015, Thailand OTTO group contacted with us from Internet. They are finding the trustable supplier of S355/2H seamless pipe for the cable car supporter. Due to the special using of the pipes, they are very careful and serious when choosing the supplier. After one months contact and discussion by email, they come to our company. We drive to the pipe mill for visit of 2 days. Through this visit, they are very confident with our production ability and products quality. Finally, they accept the grade we suggest Q345D. After back to office, they put the order of 1800 tons pipe to us directly.
