High-quality raw materials - silicon-manganese spring steel is used, which has higher strength, elasticity and hardenability.
Easy to install and maintain-simple structure and shape, convenient installation and use, more convenient maintenance and
replacement, and high cost performance.
High-strength heat treatment - while ensuring high strength, it improves the toughness of the product, the effect of strengthening
and toughening is remarkable, and the comprehensive mechanical properties are better.
Outdoor anti-rust spray paint - isolation, moisture-proof, anti-oxidation, anti-corrosion, prolong service life and improve
protection.
