Ventilation ducts is an important part of the ventilation and air conditioning systems, which the inlet ventilation and air conditioning systems, supply galvanized sheet duct, air, heat, moisture and purification equipment, send (exhaust) air, parts, and even fans as a whole, to be effective running. Brief introduction of common duct board Features: Full computer control, stable performance, advanced technology; to improve production quality, reduce material labor costs; special ventilation pipe processing software; molding machinery to make high-quality galvanized sheet from harm, galvanized sheet duct, the inner wall of the pipe to ensure a smooth, easy to clean. Since forming flange instead of angle flange, pipe material to ensure unity, making galvanized sheet duct, pipe weight reduction, increased pipeline beauty. Stiffener can improve the strength of the pipe, saving material thickness galvanized duct board manufacturers, Yanda air conditioning (certified), galvanized sheet duct provided by the Wu County Yanda air-conditioning plant. Wu County Yanda air-conditioning plant (www.wcydkt.com) (www.wcydkt.com) Shandong Dezhou, heat, refrigeration and air conditioning equipment leader, over the years, the company is implementing the scientific management, innovation and development, honesty and trustworthiness policy, and satisfy customer needs.
