Prevent condensation: The temperature of the surface of the thermal break doors is close to the indoor temperature, reducing the possibility of indoor moisture condensation on the surface of the profile due to oversaturation. Energy saving: In winter, thermal break doors can reduce heat loss by 1/3; in summer, if there is air conditioning, thermal break doors can reduce more energy loss. Environmental protection: Through the application of thermal insulation systems, energy consumption can be reduced, and environmental radiation caused by air conditioning and heating can be reduced. Good for health: The

1. Rugged and durable, beautiful appearance, high-strength, high-toughness, corrosion-resistant aluminum alloy, anti-hit, anti-scratch, block malicious intrusion outside the door, and more effective safety protection. Strong weather resistance, anti-aging, anti-rain, anti-corrosion, and long service life. 2. Applicable installation space. The aluminum rolling shutter doors is suitable for any installation opening. The aluminum rolling shutter doors is rolled up above the installation opening and only takes up the height space of the upper part of the hole. 3. Satisfactory silent operation, the silent operat

Aluminum door and aluminum windows profiles have high dimensional accuracy, and the frame and fan are closely matched. However, because the frame and fan components of plastic steel doors and windows are welded, their air tightness should be slightly better than that of screw-connected aluminum alloy doors and windows, but the two are still in one Grade level. Unqualified aluminum doors and aluminum windows, due to the influence of sunlight, air, rain, etc., will cause deformation of the aluminum profile, and even cause the glass to break and fall off, and the thickness of the oxide film is thin.

After the surface of the aluminum alloy is electrochemically treated, it can show the colors of ancient lead liver copper, golden, silver and white, etc., which can be selected arbitrarily, and it is oxidized and shiny. The window sash frame is large and can be inlaid with a larger area of glass, allowing sufficient and bright indoor light, enhancing the contrast between indoor and outdoor facades, and making the living room more layered. Aluminum alloy materials are mostly hollow-core thin-wall composite cross-sections, which are convenient to use and reduce weight, and the cross-section has high bending stren
