Professionals in the construction industry all know that the factors causing water seepage on metal roofs are quite complex. In addition to the defects in the building structure itself, roof waterproofing and leakage repair also have the damaging effect on the metal structure caused by external force imbalance. Due to their unique roof material characteristics, metal roofs such as steel structures can easily cause water leakage due to structural design, material selection, installation and construction, deformation and vibration, etc., especially when the temperature difference changes significantly, water leakage is more prominent. When the metal roof of an industrial factory leaks, it will directly affect a series of links such as production equipment, product quality, and supply guarantee, and will directly cause economic losses. Especially for precision instrument industries such as electronics, instruments, and photovoltaics, high-precision fields such as automobiles and aerospace, production industries such as pharmaceuticals, tobacco, and food processing, manufacturing industries such as papermaking, textiles, and furniture panels, and logistics and warehousing. The economic losses and related losses are immeasurable. So what are the causes of water leakage from metal roofs? In the design process, the roof slope is small, and excessive water accumulation leads to roof leakage
In the design process, the local environment and precipitation conditions of the building are not considered thoroughly, resulting in the roof slope being too small and slow, causing the rainwater to not be discharged in time, and excessive water accumulation. Causing water seepage on the roof.
Roofing materials are easily deformed, causing leakage at the joints
Steel structural materials have large thermal conductivity. When the temperature difference between climate and environment changes greatly, the material will repeatedly expand and contract with heat, causing the steel plate to deform, even at the overlap. produce larger displacements. At the same time, the material is prone to elastic deformation under the action of external forces such as wind load and snow load, so it is easy to cause water leakage at the metal plate interface.
The details of the construction process are not in place, and construction joints are prone to appear, causing leakage
During the construction process, due to various reasons, workers failed to strictly follow the construction technology and procedures. During construction, they inevitably stepped on the roof, causing damage to the flatness of the roof. There are even small cracks.
Corrosion and aging of metal roofs
Metal roofs exposed to the outdoors for a long time are prone to rust, aging and other problems, and their protective functions will be reduced accordingly. At the same time, the vibration of refrigeration, exhaust and other equipment in industrial plants during use will affect the steel structure roof with an excessive span, causing deformation of the roof panels, and even serious problems such as water accumulation and gaps in the overlap joints.
In order to solve this problem, Ningde City, Fujian Province Xinjian Gong Waterproof Material Technology Co., Ltd. has developed and produced a high-elastic polymer waterproof coating made of pure acrylic and high-quality pigments and fillers that can be used for exposed construction. Brand special waterproof coating for metal roofs. Its high-quality raw materials and special preparation process give the product extremely strong elasticity, flexibility, water resistance, anti-ultraviolet, anti-aging and other functions. After the product is cured and cross-linked, a solid and seamless coating is formed, supplemented by stitched polyester cloth. Excellent system, integrating waterproof and protective functions with heat insulation effect. It can be firmly bonded to the surface layer of various base materials, has excellent flexibility, crack resistance, water resistance, weather resistance, outstanding outdoor durability and UV resistance, and is especially suitable for waterproof construction and maintenance of metal roof projects. , providing a complete solution for metal roof lighting panels, protruding roof pipes, fan openings, metal plate lap joints, reinforcing screws, gutters and other waterproof weak parts. It can also be used for directly exposed concrete roofs, asphalt roofs, etc. Other roof waterproofing and repair systems. The products are divided into ordinary types and heat-reflective types, and comply with the "Acrylic Highly Elastic Waterproof Coating for Metal Roofs" standard.
