grade 09cupcrni-a top manufacturer in China

The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, grade 09cupcrni-a tube.

The company has formed a production scale of steel plates, steel pipes, steel profiles, and other products, with a planned layout of science, advanced grade 09cupcrni-a technology and equipment, reasonable resource allocation, environmental protection, energy saving and high efficiency. BBN company has become a large-scale iron and steel enterprise integrating steel grade 09cupcrni-a production, mineral resource development, steel structure and engineering construction, real estate and modern logistics.

Structural steel is a category of steel construction material that is produced with a particular cross section or shape, and some specified values of strength and chemical composition. grade 09cupcrni-a, Structural steel plates are normally supplied in the as-rolled condition. Our structural steel plate are supplied with thickness range 3mm to 350mm. The plates may be ordered normalized or stress relieved, or both. steel plates shall be normalized. steel plates and sheets shall be quenched and tempered.

We are one of the largest weathering steel stock keepers in China and even in the world. For most specs weathering steel materials, we can arrange delivery within 5 days. Meanwhile, our weathering steel price is competitive. And for weathering steel coils, we do slit, grade 09cupcrni-a plate cut and so on further processing. We can meet different size and shape needs of customers.
