Recently, Shanxi Jianlong has successfully developed the structural grade prepainted steel sheet TS350GD+AZ. This product not only has outstanding plate shape and surface quality but also meets qualified standards in various mechanical properties, corrosion resistance, and other indicators. The product is mainly used to produce prepainted steel sheet tiles for steel structure buildings. It has excellent molding and a beautiful surface, and the overall effect has won high recognition from customers. This not only opens up the series of Shanxi Jianlong color-coated structural grade products but also demonstrates the company's strong competitiveness in color-coated technology research and development and quality control.
It is understood that the TS350GD+AZ structural grade color-coated plate has a yield strength of more than 350MPa, excellent processing performance, can bear large loads, and ensures structural stability. The product uses a hot-dip aluminum-zinc alloy substrate and is matched with a high corrosion-resistant coating. It has excellent corrosion resistance and weather resistance and can be widely used in building structures, home appliances, automobiles, machinery, transportation, and other fields, such as large venues, factory roofs, walls, doors and windows, and equipment shells, giving buildings and products a beautiful and durable appearance.
To ensure the quality of new product development, Shanxi Jianlong has implemented refined management of the entire process. In the early stage of product design, the company optimized the control range of key elements such as C, Mn, P, and S to enhance the adaptability of yield strength and elongation; during the production process, the company strictly controls steelmaking and hot rolling, and professional technicians monitor the process parameters throughout the process to ensure the excellent performance of hot-rolled coils; the cold rolling process focuses on pickling effect and dimensional accuracy, and the aluminum zinc plating process carefully sets annealing, air knife, post-plating cooling and finishing parameters to ensure the zinc layer, plate shape and surface quality; the color coating process uses high-end paint from Valspar in the United States, and accurately controls the pre-treatment and coating process parameters to ensure the high quality of product coating.
After testing, the final product yield strength of Shanxi Jianlong TS350GD+AZ prepainted steel sheet is stable in the range of 360-380MPa, the elongation is ≥22%, and the color difference, T-bend 3T, reverse impact 9J, 4H pencil hardness, organic solvent resistance test, etc. are all qualified, fully meeting customer requirements.
In the future, Shanxi Jianlong will continue to adhere to the goal of "adjusting structure, improving quality, and creating the brand", anchor the direction of high-end color coating, focus on customer needs, deeply cultivate the segmented market, and use reliable quality and excellent service as the cornerstone to providing the market with more innovative, diversified, and cost-effective color coating products and solutions.
