Unlike general steel manufactures, other than regular fresh production, we also have huge stocks. What is more, we offer cutting, welding, drilling, bending, etc. deep processing for the steel materials. That enable us to meets various A709 Gr 50S bridge steel plate steel sizes and shapes requirements of clients.So, if you have any steel demands, or steel processing needs, please do not hesitate to contact with us. We will try our best to make you stisfied.
Hot Rolled Plates A709 Gr 50S bridge steel plate Machining After final forging/forming and Heat treatment process, all the pipe Fittings, Flanges, Fasteners, Etc. are sent for machining i.e. and preparation, O/D and I/D matching as per dimensional codes. An Expert Q.C. engineer is involved and he keeps constant vigil on every machining operation. Step machining is carried out as required by the codes. GO and NO-GO gauges are used to check the O/D & I/D of the fittings, Flanges, etc.
On Jan. 31, 2019, BBN steel held the annual meeting with all employees, family members, and friends. It is a moment of joyand it is a moment to summarize the past and look forward.Looking back on 2018, BBN steel exported A709 Gr 50S bridge steel plate more than 2 million tons of steel materials to all parts of the world and made outstanding contributions to infrastructure construction at home and abroad. In 2019, BBN steel will make persistent efforts and forge ahead.
Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for A709 Gr 50S bridge steel plate and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
