In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel ASTM A514 structural steel material surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.
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, ASTM A514 structural steel material , 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.
Medium and heavy plate ASTM A514 structural steel material inventory spot: 23*3190*9220, 23*2470*8400, 22.5*3050*7300, 23*3500*10800, 21*3500*8840, 22*3400*11550, 29.5*1750*7150, 25*2500*12000, 27*1500*5000, 36*2720*7950, 27*1920*6000, 25*2630*3300, 26*3480*6000, 27*1800*6000, 23*2430*12370, 22.5*2560*6000, 43.5*1600*6000, 28.5*2500*6700, 32*1850*6000, 27.5*3100*6390, 48.5*1600*6000, 23.5*3300*14000, 33*3500*7050, 50*1600*6000.
Phosphorus is a very harmful element in ASTM A514 structural steel material steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of ASTM A514 structural steel material steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
