Aluminum Strip For Shutter Door

The rolling shutter doors made of aluminum strip for shutter door are beautiful in appearance, which can meet the needs of modern city construction. The colorful rolling shutter doors also make the city more beautiful. The 3004 aluminum strips alloys with manganese as the main alloying element contain approximately 1.0-1.5% manganese. The hardness and price of 3004 are higher than 3003, and the extensibility is also higher than 3003. The grade and temper of aluminium strip for shutter door are 3004H16, 3005H16 and 3105H26, the thickness range is 0.21-0.6mm, while conventional thickness are 0.22mm, 0.23mm, 0.25mm, 0.26mm, 0.27mm, 0.4mm, 0.45mm, etc., can be customized according to customer needs. The conventional width of aluminum strips for shutter door are 127mm, 133mm, 138mm, 187mm, etc., can be cut according to customer needs. The surface of aluminum strips is coated with polyester anti-scratch paint roller, which has good anti-scratch effect, and is the choice of many rolling shutter door manufacturers.
 

Surface treatment process of aluminum strip for shutter door are: 1) unwinding; 2) flattening; 3) roller coating: send the flattened aluminum strip to the roller coater, and the roller coater paints the aluminum strip with a paint thickness of 0.04 ~0.06mm; 4) Baking paint: send the double-sided painted aluminum strip into the baking box, and the baking box bakes the aluminum strip. The temperature in the baking box is set to 260℃~280℃, and the time to pass through the oven is 30 to 120 seconds; 5) Embossing: Cool the high-temperature aluminum strip to 38°C to 50°C, and then send it to the embossing machine for embossing treatment; 6) Coiling. The surface treatment for rolling shutter door aluminum strip coils are paints, cools, and embossing on both sides of the aluminum strip coil at the same time, so that the aluminum strip coil does not fade during embossing, the color is beautiful, and it can Improve the strength of the aluminum strip coil, reduce the production process, and reduce the cost of equipment.
 

The aluminum alloy rolling shutter door can be sprayed with various colors and patterns on its surface, and it can also be coated with uneven wood grains, sand grains, etc., to show its noble temperament. The unique material and structural design of the aluminum alloy rolling shutter door can effectively prevent strong light and ultraviolet radiation, completely solve the greenhouse effect of sunlight on the room, suitable for various climate and weather changes, and have a long-term effect on the indoor environment. The protective effect, through experiments, shows that the shutter rate of the shutter doors and windows can reach 100% to the sun, and the shelter rate to the temperature can reach more than 95%. The advantages of aluminum strip for shutter door are:
1, The colors are diversified and can meet the needs of modern city construction;
2, The process is pollution-free and is an environmentally friendly product;
3, Low price and long life.
