The company attaches great importance to systematic management, and has passed the A709 Gr 36 bridge steel plate ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on A709 Gr 36 bridge steel plate quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.
The steel grades A709 Gr 36 bridge steel plate of thick steel plate are basically the same as those of thin steel plate. In terms of steel types, in addition to the bridge steel plate, boiler steel plate, automobile manufacturing steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate, some kinds of A709 Gr 36 bridge steel plate steel plates, such as automobile girder steel plate (2.5-10 mm thick), checkered steel plate (2.5-8 mm thick), stainless steel plate, heat-resistant steel plate, etc., are crossed with the thin plate.
The boiler steel plate has small strain aging sensitivity, especially in the corresponding working temperature range, a certain value of aging impact energy must be guaranteed;The boiler steel plate has low notch sensitivity, which can prevent steel from cracking in welding, opening, and local stress concentration areas;The A709 Gr 36 bridge steel plate, boiler steel plate has good welding performance;The A709 Gr 36 bridge steel plate, boiler steel plate has a good microstructure, white spots and cracks are not allowed.
Quenching Improve the hardness of A709 Gr 36 bridge steel plate steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of A709 Gr 36 bridge steel plate steel and comprehensive mechanical properties.
Our company supply various size and thickness A709 Gr 36 bridge steel plate, hot rolled plates. Plate thickness is available ranging 3mm to 350mm. Steel coils thickness are supplied in max. 25mm. Tolerances for carbon steel coils for conversion to: For minimum gauge orders, thickness and width tolerances are in accordance with the respective ASTM specifications of A568 for thicknesses of less than 0.230 inches(exclusive), and A635 for thicknesses of 0.230 inches to 1.00 inch, inclusive.
The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel. It can provide customers with drawing design, A709 Gr 36 bridge steel plate deep processing services and installation solutions. 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world.
