1. ChangZeng adopts standard and safe production process. Its excellent tensile strength and yield strength contribute to the quality of the final product
2. Shanghai ChangZeng Metal Co., Ltd. has always adhered to the management tenet of 'Quality Products·Sincere Service'. It is highly resistant to mechanical and chemical degradation
3. The product has a stable and constant chemical composition and physical properties which are determined by the internal structure. It can be hot rolled to have malleability
4. The product has appropriate effective porosities which are interconnected. The porosity is important for storing water content and air. Its material can be comprised of higher-grade alloys such as stainless steel or molybdenum steel
5. The luster of the product is determined by the reflectivity, refractive index, or absorptivity of the product. The better the luster, the higher the visible light reflectivity. It is highly resistant to corrosion and oxidation
1. Shanghai ChangZeng Metal Co., Ltd. has strengthened the equipment, supplies, personnel and technical reserves of 3 sch 40 steel pipe .
2. We have set up one ambitious goal. We will take the lead in this industry in the coming years. By implementing quality strategies, we will upgrade all processes from raw materials to packaging.
