Aluminum blinds What characteristics: 1, light weight, high strength: aluminum alloy mostly thin-walled hollow core portfolio section, easy to use, reduce weight, and the cross-section has a high flexural strength, doors and windows made of durable, small deformation . 2, good sealing performance: aluminum itself is easy to squeeze, cross-sectional profiles of precise size, machining accuracy. Optional waterproof, elasticity and durability are relatively good sealing materials, such as layering and silicone rubber sealant series. In profile, the various seals fixed groove section has been accompanied by the extrusion process is completed together, to install the sealing material for the creation of favorable conditions. 3, beautiful shape: anodized aluminum surface after treatment, the liver can present the ancient copper lead. Gold, silver and other colors, you can choose any of Sichuan, after oxidation shiny and smooth. Large sash frame, can insert large areas of glass, so brightly lit interior, enhanced interior and exterior facade between the actual situation contrast, make the room more rich layers. 4, corrosion resistance: aluminum alloy oxide layer does not fade. Do not fall off, no painting, easy maintenance, no maintenance. Shutters, blinds, Guangdong, longtai metal provided by Linqu longtai Metal Products.
