Since its establishment, the company has always adhered to the enterprise spirit of "solid feet and lofty ideals, dare to create and take responsibility, and dedicate to work". After years of careful management, the company has achieved the double improvement of A709 Gr 50W bridge steel plate capital strength and scale expansion, gained wide recognition and general praise from all walks of life, further realized specialized and large-scale operation and optimized allocation of resources, and effectively improved the A709 Gr 50W bridge steel plate overall strength, competitiveness and anti risk ability of the company.
Q690D grade is a low-alloy high-strength structural steel, belonging to the structural steel category. Q690D steel plate executive standard: GB/T16270-2009. Q is the expression of yield strength, 690 is its lower limit yield value, and D is its grade. This grade also has a higher yield strength and tensile strength. Q690 series grades also include Q690C, Q690D, Q690E, Q690F. Delivery status of steel A709 Gr 50W bridge steel plate: It should be delivered in quenched and tempered state. In addition, this grade can be delivered according to some special requirements of customers, but it should be indicated in the contract.
The corten plates A709 Gr 50W bridge steel plate offer high tensile, yield and mechanical strength at the elevated temperature. These plates provide high toughness and harness at the high temperature and cryogenic temperature as well. The application of corrosion Resistant Steel Plates is- these plates are used in the number of industries like landscape building, an automobile company, fertilizers, marine industry. The plate is used in because of its good elasticity, ductility, thermal and electrical conductivity. We follow all the industry-standard both national and international standards.
Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, the development of corrosion into steel material is slowed down, and the atmospheric corrosion resistance of steel material is greatly improved. A709 Gr 50W bridge steel plate, Weathering steel is a kind of steel system which can be used thinly, exposed or simply painted, and make products resistant to corrosion, prolong life, save labor and reduce consumption, upgrade and replace.
