Galvanized flange plate duct is characterized from a flange to reduce the weight of the wind pipe, galvanized iron duct processing, good sealing performance, appearance, high strength, quick and easy installation, low cost of production. The use of flange plate duct processing pipeline not only produced by a conventional duct inefficient human labor becomes efficient machinery production, Haidian galvanized iron duct, greatly reduce the labor intensity and improve work efficiency and reduce the cost of the project. Front flange plate duct construction equipment mains should engineer, will the various types of pipes, tin wind pipe thickness, single line drawn on a plan. Each pipeline with a colored pens, integrated in the intersection point of its elevation, to see if there are inconsistencies, to discover, to solve the problem before installation. In order to reduce investment, save space, reduce storey, some laying pipes without slope requirements, you can wear the beam laying. Only after this step in order to properly install the duct applications. Sheet metal duct processing, air conditioning Shenglong (online consultation), Haidian galvanized iron duct provided by the Texas Shenglong ventilation and air conditioning plant. Texas Shenglong ventilation and air conditioning plant (www.fengguan666.com) (www.dzsltfkt.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
