Beautiful office, three-dimensional sense: When the pipe as an architectural feature and must be exposed, galvanized sheet duct pictures, beautiful and elegant shaped flange duct would be the best choice. Duct Unicom is mainly used for air circulation between the two places, Kaifeng galvanized sheet duct, played the role of ventilation. Flange plate mainly by Corner, flange clamps, galvanized duct board production, and with the wind pipe flange integrally connected, although the cost of this form of air duct is low (reducing the amount of angle, reducing the production angle The amount of artificial flange) Kaifeng galvanized duct board, Yanda air conditioning, galvanized duct board thickness by Wu County Yanda air-conditioning plant. Kaifeng galvanized sheet duct, Yanda air conditioning, galvanized duct board thickness 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.
