We have introduced more than 50 sets of advanced BP440 bulletproof steel plate production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, BP440 bulletproof steel plate steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.

Weathering steel alloys like Corten A/B were developed for hard-wearing industrial applications to eliminate the need for costly finishing and refinishing. Primary alloying elements in the steel (copper, chromium, and nickel) actively cause atmospheric corrosion at the surface to generate a hard, corrosion-resistant patina. This protective layer actively and continuously regenerates when Corten steel BP440 bulletproof steel plate is subjected to weathering influences, including airborne pollutants, humidity, and rain.

37SiMn2MoV steel is high-grade quenched and tempered steel. BP440 bulletproof steel plate, 37SiMn2MoV steel has excellent comprehensive mechanical properties, good heat treatment process, good hardenability, low sensitivity to quenching crack, high resistance to tempering, very low temper brittleness, good high temperature strength and low temperature toughness. Chemical composition of 37SiMn2MoV steel: C: 0.33-0.39, Si: 0.60-0.90, Mn: 1.60-1.90, Mo 0.40-0.50, V: 0.05-0.12. After quenching and tempering, 37SiMn2MoV steel is usually used to manufacture heavy load and large section important parts.

Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel BP440 bulletproof steel plate produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.

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 BP440 bulletproof steel plate, carbon structural steel Q235 has good combination of strength, plasticity and welding properties.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
