Shenyang Zishenlong Light Steel Color Plate Co., Ltd. utilizes a variety of high - quality materials in the construction of its steel sheds. The cornerstone material is, of course, steel. The company sources premium - grade steel that meets strict international standards for strength, durability, and corrosion resistance. Galvanized steel is commonly employed, which undergoes a process of coating the steel with a layer of zinc. This zinc coating acts as a protective barrier, preventing rust and oxidation, and significantly enhancing the lifespan of the shed. For the structural components, such as the main frames, beams, and columns, hot - rolled steel is often used. Hot - rolled steel offers excellent strength and rigidity, making it ideal for supporting the overall weight of the shed and withstanding external forces like wind and snow. In addition to steel, the company uses various types of roofing and wall panels. Sandwich panels are a popular choice, which consist of two outer layers of steel and an insulating core material in between. The core material can be made of different substances, such as polyurethane (PU), polystyrene (EPS), or rock wool. Polyurethane - insulated sandwich panels provide high thermal insulation, reducing heat transfer and helping to maintain a stable internal temperature within the shed. Rock wool - filled panels, on the other hand, offer excellent fire resistance in addition to insulation. For the connections and fasteners in the steel shed, high - strength bolts and screws are used. These fasteners are designed to securely join the steel components together, ensuring the structural integrity of the shed. The company also uses weather - resistant sealants and gaskets to prevent water ingress at joints and openings. These sealants are formulated to withstand various environmental conditions, maintaining their elasticity and sealing properties over time. By carefully selecting and using these high - quality materials, Shenyang Zishenlong Light Steel Color Plate Co., Ltd. ensures that its steel sheds are not only robust and durable but also offer optimal performance in terms of insulation, weather resistance, and overall functionality.
