1. Light weight, which can reduce the building load - the volume weight of color steel phenolic duct is 2.98kg/m2, while the volume weight of iron sheet duct (O.8mm thick) is 7.O8k9/m2, so color steel phenolic foam is used; At last, the structural load of the building can be greatly reduced, and the safety factor of the building can be increased, which is particularly beneficial to the framed steel structure building-

2. Save headroom and improve effective space - color steel phenolic air duct does not need to be pre insulated for construction space, but can be installed on beams, walls and roofs without installing silencers, so it can effectively use building space and improve indoor headroom - iron sheet air duct needs to be insulated on site, so a certain amount of installation space needs to be protected, resulting in a waste of building space-

3. Faster production and shorter construction period - color steel phenolic air duct is formed at one time in the factory. The on-site production is convenient and fast, with small workload. Due to light weight and low requirements for hoisting, the construction efficiency is high, and the construction period is far less than that of iron sheet air duct. According to the on-site calculation, the installation efficiency of color steel phenolic air duct is 3~4 times higher than that of galvanized iron sheet air duct, which can greatly shorten the construction period, enable the owner's property to be put into use as soon as possible, and generate benefits as soon as possible!
