The double-layer aluminum alloy rolling shutter door is a great improvement on the technology and function of the traditional rolling shutter door. The door is mainly used for the exterior doors of medium and high-grade workshops, especially for the logistics warehouse with high requirements for work efficiency.

　　双层铝合金卷帘门都是采用双层高强度、高韧性、耐腐蚀铝合金挤压成型，坚固耐用、可靠。外表采用特殊表面处理工艺，耐久性强，抗老化、抗腐蚀、不褪色，密封性强，可抗风压，美观、不生锈、易维护，长久如新。

　　Double layer aluminum alloy roller shutter doors are made of double layer high strength, high toughness and corrosion-resistant aluminum alloy by extrusion, which are durable, safe and reliable. The special surface treatment technology has strong durability, anti-aging, corrosion resistance, no fading, strong sealing, anti wind pressure, beautiful, rusty, easy to maintain, and long lasting.

　　双层铝合金卷门与传统的卷帘门相比的优势有：

　　The advantages of double-layer aluminum alloy rolling door compared with traditional rolling door are as follows:

　　1.双层的帘片在经过特殊的工艺处理，能具有抵抗自然灾害的能力；目前市场上的双层帘片有很多通过了性抗风压性能测试，如湘联的防飓风帘片能抵抗11级大风；坚固防护，放心：高强度、高韧性的铝合金材料，结合防上推装置，犹如一道坚固的防护墙，将您的人身、财产的保护起来，窃贼在外无计可施；

　　1. The double-layer curtains have the ability to resist natural disasters after special processing. At present, many double-layer curtains on the market have passed the international wind pressure resistance test, such as the anti hurricane curtain of Hunan union can resist the 11 level wind; strong protection, safe and assured: high strength, high toughness aluminum alloy material, combined with anti push safety device, is like a solid protection The wall will protect your personal safety and property safety in an all-round way, and there is nothing for thieves to do outside;

　　2.隔音降噪，免除干扰：卷帘门材质隔音系数大，能有效降低噪音污染；

　　2. Sound insulation and noise reduction to avoid interference: the rolling shutter material has a large sound insulation coefficient, which can effectively reduce noise pollution;

　　3.保温隔热，：双层的门板设计，保温效果。

　　3. Heat preservation and insulation, energy conservation and environmental protection: double layer door panel design, excellent heat preservation effect.
