Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel, Zincalume steel, aluminized zinc steel (aluzinc steel), SGLC. The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600 ° C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a dense quaternary crystal of an alloy.From the point of view of the degree of coating, the Galvanized Steel Coil is mainly the zinc plated on the coating, while the coating of the galvalume steel coil not only has zinc, but also has an extra part of aluminum.Galvalume steel sheet (coil) has better atmospheric corrosion resistance.

The steel-plastic composite spiral wound pipe is based on the plastic sheet structure strip. The upper part is provided with a T-shaped cap and a special shape steel strip is used to enhance the loop stiffness, strength and toughness of the pipe, and enhance the flexibility of the ring and the pulling of the seam. The degree of stretching improves the connection stability, and has the advantages of light weight, strong impact resistance, not easy to break, small water flow resistance, and good adaptability to uneven settlement of the foundation. The steel-plastic composite spiral wound pipe project has been included in the 100 key high-tech industrial projects in Liaoning Province in 2007. The product has applied for 3 national patents.
Recently, the steel-plastic composite spiral wound pipe developed by Liaoning Far East New Pipe Industry Development Co., Ltd. passed the scientific and technological achievements appraisal organized by the Science and Technology Department of Liaoning Province. The identification results show that the product has reached the international advanced level.
