Its muffler for 5-15dB (A) zinc steel shutters, pressure loss ≤30Pa, per square meter used in flow 1500m3 / h ~ 3000m3 / h. Secondary oxidation coating all aluminum construction with stainless steel, galvanized steel material. Rain, fire used in any weather conditions. Airfoil blade muffler can minimize airflow resistance and reduced noise transfer. Modulo assembled into a series of standard size of acoustic louvers. Painted in different colors according to need in an anechoic coating outside louvers. The installation process does not go smoothly switch electric shutters installation process does not go smoothly switch found blinds should check is not a problem with the installation of locks. Remove the latch plate tongue and groove with a chisel repair, adjust the position of the door latch opening and then install the bolt plate. Question three, the installation process is not perpendicular to the electric side of the hole caused by the installation process is not perpendicular to the electric side of the main entrance is no piece looking straight skids should rework pad level, with a long tape measure and then install the correct mat board. 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 galvanized steel shutters price, made of doors 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 blinds sold galvanized, enhanced interior and exterior facade comparison between the actual situation, 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. Galvanized shutters, blinds, Hebei, longtai metal provided by Linqu longtai Metal Products.
