The company has five major departments: steel plate production department (including quality inspection team), sales department, market development department, after-sales and logistics department, and finance department. The backbone of steel business from all over the country, with the chairman as the core, integrates self-confidence, independence, passion and responsibility, and strives for excellence! All people share the same belief: "Being a refined steel product line rewards customers, strengthen the steel industry, and realize the corporate dream!
sa573gr.70 steel equivalent, low alloy high strength steel has good atmospheric corrosion resistance and is widely used in engineering structure construction. Most of the engineering structures are used in the atmosphere or marine environment. A small amount of Cu, Ni, Cr, P and other elements are added to the low alloy high strength steel, which effectively improves the corrosion resistance of the engineering structure in the atmosphere, sea water and soil. If 0.2% - 0.5% copper, 0.05% - 0.1% phosphorus and aluminum are added, the corrosion resistance of steel can be improved obviously, and the effect of adding copper and phosphorus at the same time is the best.
The quality grade of common carbon structural steel Q235 can be divided into A, B, C, D and E. Relatively, the quality of Q235A is poor and that of Q235E is the highest. Different grades of Q235 steel have different characteristics, which are mainly different from the impact temperature: Q235A does not require impact toughness test; grade Q235B is for room temperature (20℃); grade Q235C is for 0℃; grade Q235D is for - 20℃; grade Q235E is for - 40℃. The sa573gr.70 steel equivalent, carbon structural steel Q235 has good combination of strength, plasticity and welding properties.
The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
