Compared with traditional angle steel flange connection technology, thin steel flange manufacturing and installation technology has the advantages of advanced technology, stable product quality, good forming quality, reducing environmental pollution, reducing labor intensity and accelerating construction progress. So what's the difference between thin steel flange tube and corner flange tube?
1. Lower material losses
Because the metal rectangular air duct thin steel flange air duct generally uses computer lofting, laser cutting, water production. Compared with traditional manual lofting cutting, it has the advantages of high processing accuracy and low cutting loss.
2. Preserving corner flange
在传统角钢法兰风管,风管如600毫米* 300毫米,通常使用∟30角3.6米* 1.37公斤* 4 = $ 20元,管占地面积1.8平方米,节省约11元每平方米。
In the traditional angle steel flanged duct, such as 600 mm * 300 mm, the duct is usually used 30 angle 3.6 m * 1.37 kg * 4 = 20 yuan, covering an area of 1.8 square meters, saving about 11 yuan per square meter.
Because flanges are made of galvanized steel sheets, the number of galvanized steel sheets has increased by about 4%, followed by the use of automatic production lines, the production accuracy and quality are easier to control.
In addition, due to the reduction of section steel and anti-corrosion engineering, it also reduces the pollution of paint to the environment, and has better economic and social benefits.
Production of metal rectangular air duct and thin steel plate flange air duct, factory customized processing cost of 14 yuan per square metre, while the processing cost of conventional angle steel flange air duct is about 22 yuan per square metre.
Every square metre saves about 8 yuan of labor.
4. Save the cost of construction machinery
Because of the centralized customization of the factory, thin steel flange air duct reduces the cost of processing machinery and saves the cost of construction machinery.
Therefore, from the three aspects of construction efficiency, engineering quality and engineering economic benefits, it can be seen that thin steel flange air duct has great advantages over angle steel flange air duct. We can choose according to the actual situation of Shandong air duct production and construction.
