　　Guangdong Shantou Steel Skeleton Lightweight Plate Carefully Constructed GLB3012-1

　　The steel structure lightweight energy-saving composite roof panel is made of cold-formed thin-walled steel as the outer frame; Using steel truss or reinforced concrete as auxiliary ribs; Using high-performance ultra lightweight foam cement or other insulation materials as the core material; A new type of roofing material composed of alkali resistant glass fiber mesh reinforced polymer cement mortar (GRC) as the upper and lower layers.

　　The steel structure lightweight energy-saving composite roof panel not only inherits the reliability of traditional reinforced concrete slabs, abandons the factors of heavy weight and high energy consumption of traditional slabs, but also fully compensates for the defects of short service life, susceptibility to wind overturning, and lack of fire resistance of color steel plates. It meets the needs of modern light steel building roof construction and has become the choice for safe and durable roofs. It is an upgraded product of traditional roof panels.

　　Widely used in the roofs of large industrial plants, garages, warehouses, supermarkets, sports venues, exhibition centers, boiler rooms, and other industrial and civil buildings in Class I and II environments such as chemical, power, textile, and food industries.

　　Steel lightweight insulation composite roof panels include large roof panels, grid roof panels, eaves panels, skylight panels, and gutter panels.

　　Standard specification: Large roof panel: 6000mm × 1500mm

　　Grid roof panel: 3000mm × 3000mm

　　The external dimensions are determined according to actual usage requirements, with a span of 9.0m. It is recommended to use specification plates as much as possible.

　　The height of the ribs is generally between 100mm and 300mm, and can be designed according to different load and slab span requirements.

　　The thickness of the core board is generally 80mm to 120mm, designed according to sound insulation requirements and energy-saving requirements in different regions.

　　lightweight and high-strength

　　——The self weight of the slab is 1/3 to 1/4 of the weight of traditional precast concrete slabs; The built-in steel frame or reinforced concrete auxiliary ribs connected to the steel frame increase the load capacity per unit area under the same deflection conditions compared to similar products.

　　——The composite insulation core material has excellent insulation performance, and insulation materials with the same thickness and thermal conductivity can be selected according to the energy-saving design requirements of various regions, meeting the heat transfer coefficient requirements of energy-saving regulations in various regions.

　　——For roof panels with fire protection requirements, the core material is mainly non combustible and has a fire resistance of not less than 2.0 hours; The average sound insulation of 120 thick lightweight core material shall not be less than 40dB.

　　——Its special structure can be used as a venting roof for buildings. When it occurs, its insulation core layer can quickly release pressure, which can prevent damage to the main structure and steel frame of the roof panel, avoiding secondary damage to machines and personnel caused by the collapse of the rear roof.

　　——The design load is safe, resistant to negative wind pressure, not afraid of snow, and avoids various defects of color steel.

　　——The welding between the board and the main structure, as well as between the boards, is firm and has good overall integrity, which can meet the seismic fortification intensity requirements of 8 degrees; The surface layer is reinforced with alkali resistant glass fiber mesh cloth and polymer cement mortar, which has good crack resistance and waterproof performance.

　　——The main material is inorganic material, and the steel frame is coated with rust proof and anti-corrosion paint, which is corrosion resistant, freeze-thaw, anti-aging, durable, and has a service life of 50 years.

　　——There is no discharge of wastewater or exhaust gas during the production process, and a large amount of waste is used; During the installation process, the amount of on-site laying and wet work for insulation boards has been reduced, without causing any environmental impact; During use, the material itself has excellent thermal insulation effect, which plays an energy-saving role; After use, its steel frame and core material can be recycled.

　　——The board itself is lightweight, reducing the steel structure support system, thus greatly saving steel consumption. The foundation part can save 20% of funds, and the main structure part can save 30% of funds. The installation is simple and fast, the construction period is shortened, manpower and material resources are saved, and the overall cost is low.

　　Note: The data in this table is for reference only. The specific product technical indicators of the project shall be subject to the design requirements.

　　Easy and fast installation, no wet work on site, single shift installation can reach 1000 ㎡/day, main steps:

　　Placement: After lifting the board into place according to the design requirements, it can be welded and fixed with the roof or grid support bracket.

　　Jointing: After filling the joint with insulation mortar, it can be sealed with a special waterproof and wear-resistant coating.

　　(For detailed construction methods, please refer to the product atlas)

　　Roof panels cannot be directly used as construction work surfaces for civil engineering. When stacking and transporting construction materials on the board, protective measures should be taken, and the stacking weight and construction load should not exceed the external load on the board
