Background

In the building industry, along with the increasing application of the standing-seam crimping metal roof, the building roof is more attractive and elegant, and has good waterproof and drainage performances. However, the metal roof also has corresponding defects, the metal roof panel is smooth, and when the slope is large, the construction and maintenance personnel have difficulty in moving on the roof. Particularly, when a higher roof area is urgently needed to be reached from a lower roof area, the ladder stand is not arranged, and the realization is impossible. Traditional roofing cat ladder is a fixed rope on the roofing, and construction and maintenance personal through pulling the rope, difficult climbing to the eminence. Because the safety belt can not be fixed by the rope, the safety of constructors can not be ensured. Meanwhile, the rope is easily rotten and damaged due to sunlight irradiation and rain wash, and cannot be used continuously.

Because the surface of the metal roof is smooth and the slope is steep, people cannot stand. When constructors or maintenance personnel need to reach a higher position from a lower position, a set of firm ladder stand is needed; because the gradient is larger, the ladder stand is required to enable workers to fix the safety belt, and the personal safety of the workers is ensured; the metal roof needs to have good waterproof performance, and can discharge rainwater in time, so that the roof needs to be provided with a crawling ladder, and the waterproof performance and the drainage performance of the roof cannot be influenced; the roof is directly irradiated by sunlight and washed by rainwater, and the crawling ladder for the roof needs to be weather-proof and corrosion-proof, so that the roof is unbreakable, firm and durable all the year round.
