Is the Rolling Shutter Made of Iron or Aluminum?

The material of the rolling doors is not single, there are both aluminum alloy (aluminum) and steel (iron), depending on the type and purpose. ‌

Main material types

1. Aluminum alloy roller shutter: Made mainly of aluminum alloy, it has the characteristics of lightweight, corrosion resistance, and beautiful appearance, and is widely used in places such as garages, shops, and warehouses. ‌‌‌

3. Steel coil gate: including color steel plate (iron sheet sprayed with color paint), galvanized steel plate, etc., belonging to the category of iron, its deformation resistance is usually stronger than aluminum alloy, but the surface coating may rust after damage. ‌‌

3. Other common materials:

Stainless steel roller shutter: It has good stability, is not easy to rust, is easy to clean, and is often considered as one of the preferred materials. ‌‌

Crystal roller shutter door: The curtain is made of high transparency PC board, with stainless steel pipes or aluminum alloy strips inserted in the middle, which combines transparency and protection. ‌

Composite material roller shutter: Some products use double-layer aluminum alloy or aluminum alloy steel composite structure to balance performance.

Material characteristics and selection suggestions

● Aluminum alloy material: The advantages are lightweight, corrosion resistance, beautiful appearance, and easy processing; The disadvantage is that it is relatively soft and may deform under strong external impact. Suitable for scenarios that emphasize aesthetics, weather resistance, and daily convenience, such as residential garages and commercial storefronts. ‌‌

● Steel (iron) material: Its advantages include high strength, outstanding impact resistance, and deformation resistance; The disadvantage is that if the surface protective layer (such as paint) peels off, the substrate (iron) may rust. More suitable for industrial sites, factories, or environments that require high safety and structural strength. ‌‌

● Stainless steel material: It combines corrosion resistance and high strength, is easy to maintain, and has a durable appearance, but the cost is usually high. ‌‌

● Selection principle: It is not better to be thicker or more expensive, but to meet the functional requirements of specific usage scenarios (such as anti-theft, fireproof, windproof, and daylighting) and daily usage frequency. For example, fire-resistant rolling shutter doors need to meet specific fire resistance standards and may be made of steel or special composite materials.

Corresponding materials based on their purpose and function

Rolling doors can be classified into ordinary, fireproof, windproof, fast rolling shutter and other types according to their purposes, with different functional focuses corresponding to different material preferences. ‌

1‌ . Ordinary rolling shutter: commonly found in shops and garages, with a wide range of material choices, including aluminum alloy, steel, and stainless steel. ‌

2. Fire resistant roller shutter: It must comply with fire prevention standards (such as GB14102.1-2024) and is often made of steel or composite structures with built-in fire-resistant materials. ‌‌

3. Windproof roller shutter: commonly found in coastal or high wind pressure areas, emphasizing structural strength and often using steel or high-strength aluminum alloy. ‌

4. Quick rolling shutter door: commonly used in logistics and clean workshops, the material is mostly flexible materials such as PVC or PC, and the frame is often made of aluminum alloy. ‌‌‌
