Welcome to inquire! Contact: Su Wei. [捷维诺 recommend to you the star product - a total of flange angle iron flange duct duct manufacturers] refers to the bending angle or roll angle iron were stamping factory duct through a special device, angle iron after processing the two sides remain vertical angle of 90 °, no cuffs. And no wrinkles. Angle iron flange duct is divided into two: one is outward angle iron volumes (positive roll angle, opening outwards), one is the inward roll angle iron (anti-roll angle, opening inwards). Actual operation Wuqing stamping factory duct, the two sides can do vertical is 90 °, and does not have a certain degree of difficulty flanging, angle iron flange which is determined by the physical properties of the duct. Under normal circumstances, angle iron flanges used in wind whether it is a strong antiseptic properties of galvanized steel duct flange as a raw material, which also saves rust environmental pollution. Coupled with our current mechanized automated production line angle iron flange duct and duct flanges stable and reliable quality parts, raw materials, less wear and tear duct stamping factory in Tangshan, light weight, quick and easy installation, reduce engineering costs Chittagong stampings Factory duct, high-volume production methods great to meet the requirements of the construction progress of major projects. I hope these presentations can be helpful for everyone to understand. Excellent quality equipment, materials, advanced technical skills, perfect design, experienced construction personnel, strict management system and perfect after-sales service, we are confident assurance for each project, but also for our band to many sincere cooperation partners.
