Galvanized air duct does not need late maintenance in the future of the equipment, so that it can save a lot of late maintenance costs, and it does not need to worry about the problem of late use; In terms of raw materials, galvanized air duct is made of galvanized steel plate, so the life span is relatively long in use, and it is also very simple in equipment. Galvanized air duct can be manufactured at any time in the field or cut or drilled according to demand. On the equipment, it is simple to shorten the time of the equipment.

Galvanized air duct has the characteristics of fire prevention and non-combustion, and the production process is also quite convenient. Its inner wall is smooth, the resistance is small, the air tightness is good, can withstand high pressure strength. The steel plate air duct is also convenient and fast when it is made on the spot, its pressure strength is high, its strength is large, its static pressure resistance is strong, it is easy to carry, and it will not cause damage even if it is hit.

Common plate flanged air duct is also known as flangeless air duct, its main advantage is to save materials, thereby reducing project investment. In addition, the small amount of air leakage can effectively reduce energy consumption and save operating costs, so it is welcomed by construction enterprises. Compared with the traditional rectangular air duct, the production form of the common plate flange air duct is faster and more convenient, and the air leakage rate is lower.

The connection form of stainless steel and galvanized sheet air pipes produced in the automatic production line can be inserted, or directly pressed with Angle steel, or even the air pipe and the flange common plate can be formed as a whole. This kind of air duct has advanced production technology, accurate cutting, low material consumption, stable product quality, diverse varieties, smooth appearance and lines. Its air leakage is much lower than the national standard, which is conducive to the production of ventilation pipes showing the characteristics of factory, scale, standardization and automation.
