Carry out more than two spray anti-corrosion treatments on key parts such as the cut and weld of the roof gas building skeleton. Usually, the anti-corrosion measures of epoxy zinc-rich primer + epoxy mica intermediate paint + acrylic polyurethane are used to ensure the ridge ventilator's skeleton has good anti-oxidation stability. In the installation process of the steel roof ridge vent, Mcwell adopts the original full-structure waterproof technology, abandons the traditional silicone waterproof technology of the smoke vents, and effectively prevents the leakage and rust of the waterproof nodes caused by the easy aging of the silica gel, and guarantee ridge ventilator's life span. The service life of a roof smoke vent is one of the important indicators to measure its performance, but its service life is closely related to its anti-corrosion treatment process. Excellent anti-corrosion treatment technology can improve the overall quality level of the ridge ventilator.
