Detailed Service Description
Aiming at the outdoor and long-term service needs of steel structure buildings, we provide supporting anti-corrosion and full-cycle surface treatment service for large-size heavy steel welded parts, thoroughly solving the rust and corrosion problems of steel components in complex outdoor environments such as rain, humidity, salt spray and high temperature. We adopt standardized surface treatment process, which is matched with welding and assembly processes to ensure the overall durability of steel structural parts.
We first carry out full sandblasting derusting treatment, reaching Sa 2.5 grade derusting standard, completely removing oxide skin, rust stains and impurities on the steel surface, increasing the adhesion of subsequent coatings. According to the building use environment and design requirements, we provide anti-corrosion primer, intermediate paint, topcoat multi-layer spraying, as well as special fireproof coating construction for building steel structures, meeting the fire protection and anti-corrosion dual requirements of construction projects.
Suitable for all kinds of large-size steel beams, steel columns, steel frame and connecting parts, we can customize anti-corrosion schemes according to outdoor, coastal, industrial polluted and other different environments, ensuring that the steel structural parts have excellent weather resistance and corrosion resistance after treatment. The whole process is operated in accordance with building coating standards, with uniform coating thickness, no falling off and no cracking, greatly extending the service life of steel structure buildings.
