Fuzhou Huiyi Steel Structure Co., Ltd.   

Product introduction steel structures are usually made from steel and steel and other steel beam, steel column, steel truss component; weld, bolts or rivets even huawo tower connected between each component or components used. The composition of some steel structure is also used steel wire, wire rope or wire bundle and cast steel and other materials. The organizational structure of product attributes of steel is close to uniform, isotropic homogeneous, so the steel structure of the theoretical calculation result is consistent with the actual stress of steel; high strength, modulus of elasticity is also high; steel structure, good plastic and toughness, suitable to withstand vibration and impact load power can use steel structure in large span, height big, big load, dynamic effects of various engineering structures, such as industrial plant bearing skeleton and crane beam, large span roof structures, high-rise buildings, long-span bridges, the skeleton of the crane structure, tower and mast structure, petrochemical equipment, the working platform and the framework of offshore oil platform, pipeline support, hydraulic gate; it is also used in assembling the relocation of the structure, such as temporary exhibition hall, a building site with real, concrete template. Other description steel structure and technical characteristics of 1, antirust technology Steel structure surface without protection corrosion in the surrounding medium under the action of will. The corrosion rate and the surrounding medium temperature, humidity and the content of harmful substances related. Methods of corrosion prevention, is most commonly used paint protection; also used galvanized metal coating protection; or by chemical oxidation treatment measures for the protection, such as phosphate treatment. By containing copper, chromium, nickel alloy steel can improve the corrosion resistance of. 2, fire protection technology Steel is not combustible, but not fire. When the temperature exceeds 300 degrees C, yield strength and elastic modulus, tensile point were declined significantly, to 600 degrees C is almost reduced to zero. Fire prevention measures is commonly used in steel structure is wrapped concrete or brick masonry, is also available on the component surface spraying a layer of vermiculite, or other material containing asbestos cement slurry. When the steel structure on the surface of the long-term radiation heat of 150 degrees above C, application of thermal insulation layer to protect.
