Benefits of choosing reinforcement steel profile
1. Safety. Doors and windows are equipped with steel lining, which can increase the connection strength, improve the earthquake resistance and wind resistance.
2. Sound insulation. High-quality steel lining with good sealing effect and sound insulation function.
3. Anti-corrosion. The surface of the steel lining has been treated with anti-corrosion and rust, and the thickness of the zinc layer meets customer requirements, which greatly increases the service life of the steel lining.
4. Environmental protection. Use lightweight energy-saving standard steel to reduce carbon emissions.
