Double layer aluminum alloy roller shutter door, as the name suggests, is a roller shutter door made of double layer aluminum alloy curtains, which is a significant improvement in technology and function of traditional roller shutter doors. This door is mostly used for external doors in mid to high-end factories, especially suitable for logistics warehouses with high requirements for work efficiency. At the same time, it can also meet some special requirements in industries such as food processing, medicine, and chemical industry.

以湘聯卷簾門為例，雙層鋁合金卷簾門都是采用雙層高強度、高韌性、耐腐蝕鋁合金擠壓成型，堅固耐用、可靠。外表采用特殊表面處理工藝，耐久性強，抗老化、抗腐蝕、不褪色，密封性強，可抗風壓，美觀、不生銹、易維護，長久如新。

Taking Xianglian rolling shutter doors as an example, double-layer aluminum alloy rolling shutter doors are made of double-layer high-strength, high toughness, and corrosion-resistant aluminum alloy extrusion molding, which is sturdy, durable, safe, and reliable. The appearance adopts special surface treatment process, which has strong durability, anti-aging, corrosion resistance, fadeless, strong sealing, wind pressure resistance, beautiful appearance, no rust, easy maintenance, and long as new.

同時由于采用整體門框結構從而保障了門承重結構的和整體運行平穩，運行時平穩，可靠；并具有低噪音、速度快、開啟頻率高、性能好，便于布置等多個優點。

At the same time, due to the use of an integral door frame structure, the safety of the door load-bearing structure and the overall smooth operation are ensured, and the operation is stable, safe and reliable; And it has multiple advantages such as low noise, fast speed, high opening frequency, good safety performance, and easy layout.

雙層鋁合金卷門與傳統的卷簾門相比的優勢有：

The advantages of double-layer aluminum alloy rolling doors compared to traditional rolling shutter doors are:

1.強度提升：增加了一層簾片從而使門的強度在很大程度上得到了提升；

1. Strength improvement: By adding a layer of curtains, the strength of the door has been greatly improved;

2.抗災害性能提高：雙層的簾片在經過特殊的工藝處理，能具有抵抗自然災害（颶風、沙塵暴）的能力；市場上的雙層簾片有很多通過了性抗風壓性能測試，如湘聯的防颶風簾片能抵抗11級大風；

2. Improved disaster resistance: The double-layer curtain, after special processing, can resist natural disasters (hurricanes, sandstorms); Many double-layer curtains on the market have passed international wind pressure resistance tests, such as Xianglian's anti hurricane curtains, which can withstand strong winds of level 11;

3.堅固防護，放心：高強度、高韌性的鋁合金材料，結合防上推裝置，猶如一道堅固的防護墻，將您的人身、財產的保護起來，竊賊在外無計可施；

3. Durable Protection, Safe and Reliable: High strength and high toughness aluminum alloy material, combined with anti push safety devices, acts like a sturdy protective wall, protecting your personal and property safety from all angles. Thieves are helpless outside;

4.隔音降噪，免除干擾：卷簾門材質隔音系數大，能有效降低噪音污染；

4. Sound insulation and noise reduction, eliminating interference: The rolling shutter door material has a large sound insulation coefficient, which can effectively reduce noise pollution;

5.更的開啟方式：結合電機驅動，可以更方便地實現無線遙控；

5. More advanced opening method: combined with motor drive, it can more conveniently achieve wireless remote control;

6.保溫隔熱，：雙層的門板設計，保溫效果。中介填充的發泡物質不含碳氫氟化物，保持室內溫度，節省能源，綠色。

6. Thermal insulation, energy conservation and environmental protection: The double-layer door panel design provides excellent insulation effect. The foam material filled with the intermediary does not contain hydrocarbons or fluorides, maintaining indoor temperature, saving energy, and being green and environmentally friendly.
