Brief introduction of common duct board Features: Full computer control, stable performance, advanced technology; improve the quality of production, galvanized steel duct specifications, reduce labor costs material; special ventilation pipe processing software; molding machinery to make high-quality galvanized sheet from harm, galvanized steel duct production to ensure that the inner wall of the pipe is smooth, easy to clean. Since forming flange instead of angle flange, galvanized steel duct installation, ensure unified pipe material, pipe weight reduction, increased pipeline beauty. Stiffener can improve pipeline strength, Laiwu galvanized steel duct, saving material thickness 1. Yanda specializing in the production of ventilation ducts and other pipes, such as central air-conditioning pipe, standard size and other parameters can provide customized production. 2, through the wind pipe production equipment to produce a square Duct mechanism, semi-duct device: eg: Duct production of three-wire / wire / line, TDF TDF flange machine, multi-locking machine, hydraulic Flap, vertical sewing machine, supporting the use of several to produce a square duct. 3, automatic air pipe production equipment: automatic air duct by using a one-time production of five lines forming a square duct, greatly improve the production efficiency. Laiwu Yan galvanized steel duct of air-conditioning _ _ galvanized steel duct installation by Wu County Yanda air-conditioning plant. Laiwu Yan galvanized steel duct of air-conditioning _ _ galvanized steel duct installation is Wu County Yanda air-conditioning plant (www.wcydkt.com) (www.wcydkt.com) this year introduced a new upgrade, the above picture is for reference, please call Tel picture on this page or to obtain the latest information, contact: Wu Yusong.
