●High-quality raw materials
—Using silicon-manganese spring steel with higher strength,elasticity and hardenability.
●Easy to install and maintain
—The structure is simpler,easy to install and use,more convenient to repair and replace,and has high cost performance.
●High-intensity heat treatment
—While ensuring high strength,it also improves the toughness of the product.The strengthening and toughening effect is significant,and the comprehensive mechanical properties are better.
●Outdoor anti-rust spray paint
—Isolation, moisture-proof, anti-oxidation, anti-corrosion, extending service life and improving protection.
