JMA Aluminum has deep technical accumulation and rich experience in the research and development and production of aluminum alloy materials. The GR52-VI series swing doors may use aluminum alloy materials with special formulas or advanced processes to make them excellent in strength, toughness, corrosion resistance, etc. For example, by optimizing the alloy composition and smelting process, the strength of the material is improved, making the door body more durable and able to withstand greater external impact, and it is not easy to rust and corrode under harsh environmental conditions.
The GR52-VI series swing doors may have innovative structural optimizations to make them have better sealing and stability. For example, the multi-cavity structure design increases the heat insulation and sound insulation performance of the door body, while improving the overall strength of the door; at the junction of the door frame and the door leaf, a special sealing strip and sealing structure are used to effectively prevent the penetration of air, water and noise, providing users with a quieter and more comfortable use environment.
Quality and safety certification: ISO9001
