镀锌螺旋风管的优点
Advantages of galvanized spiral air duct
1、强度高、阻力小、密封性能好、外形美观、安装简单、使用寿命长；
1. High strength, small resistance, good sealing performance, beautiful appearance, simple installation and long service life;
2、使用的原材料均为本钢产镀锌钢板；
2. The raw materials used are all galvanized steel plates made of Benxi steel;
3、内外壁光滑，风道阻力小，送排风河北立体车库 消防报警器塑料配件 电缆接地箱 电缆保护接地箱 塑料土工格栅 消弧线圈装置时不产生二次噪声，降低能耗，节约运行费用；
3. The inner and outer walls are smooth, the resistance of air duct is small, there is no secondary noise in the air supply and exhaust, the energy consumption is reduced, and the operation cost is saved;
4、可现场制作、可切割、可钻孔、可开洞、安装简单，省工省时，缩短工期；
4. It can be made on site, cut, drilled, opened, installed simply, save labor and time, and shorten the construction period;
5、镀锌螺旋风管安装完工后不需要维护，减少维护经费。
5. No maintenance is needed after the installation of galvanized spiral air duct, so the maintenance cost is reduced
