Prefabricated Assembly Factory Building Roof Panel

There are mainly two types of prefabricated assembly factory building roof panels: prefabricated assembled lightweight steel-structured roof panels and prefabricated ALC partition walls (which can also be used as roof panels).

Prefabricated Assembled Lightweight Steel-Structured Roof Panels:

• Price and Specifications: Prices vary depending on the minimum order quantity. The price for a minimum order of 1 square meter is 110.00 yuan, for 100 square meters it is 105.00 yuan, and for 1000 square meters it is 100.00 yuan. Product specifications can be customized according to the project, with thickness tailored as needed and shapes made according to drawings.
• Performance Characteristics: These panels use high-quality galvanized cold-formed thin-walled steel as the load-bearing framework, offering lightweight strength and corrosion resistance, meeting 50-year durability requirements. The framework is filled with A-grade non-combustible insulation materials such as rock wool, glass wool, or cement polystyrene granules, providing excellent thermal insulation, fire resistance, and sound absorption properties. The fire resistance limit can reach up to 4 hours, and sound insulation can reduce noise by up to 55 decibels. They significantly reduce structural loads, with a self-weight approximately 40% lower than traditional concrete roof panels, reducing the load on building beams, columns, and foundations, lowering construction costs, and enhancing structural safety and seismic performance (suitable for areas with seismic fortification intensity ≤ 8 degrees).
• Construction Advantages: Construction is fast, adopting a dry construction method of factory prefabrication and on-site lifting and welding, eliminating the need for formwork, steel bar binding, and concrete pouring, and不受季节天气影响 (not affected by seasonal weather). The construction period can be shortened by about half. They are multifunctional, integrating load-bearing, enclosure, thermal insulation, fire prevention, and pressure relief functions, effectively meeting the fire prevention and pressure relief needs of special buildings such as chemical plants and warehouses. Their excellent thermal insulation properties help reduce heating, ventilation, and air conditioning (HVAC) energy consumption in factories, aligning with green building energy efficiency standards.

Prefabricated ALC Partition Walls (which can also be used as roof panels):

• Core Product Performance: Also known as autoclaved aerated concrete wall panels, these are factory-prefabricated large-size panels with built-in reinforcement structures, integrating multiple properties such as enclosure, thermal insulation, fire prevention, sound insulation, and lightweight. Their density is only 1/4 to 1/3 of that of ordinary concrete, with a dry density controlled between 400 and 725 kg/cubic meter, significantly reducing building self-weight, optimizing structural loads, and enhancing building seismic performance. They have a low thermal conductivity coefficient, providing better thermal insulation than traditional brick walls, reducing air conditioning and heating energy consumption, and helping buildings meet energy efficiency standards. They are inorganic non-combustible materials, with fire resistance limits meeting national standards, and their porous structure effectively blocks noise, improving building comfort. They are also regularly shaped, easy to cut, nail, and saw, suitable for dry construction, with minimal on-site wet work, significantly shortening the construction period and reducing construction pollution.
• Application Scope: They can be used simultaneously as interior partition walls, exterior wall panels, roof panels, floor slabs, etc., compatible with various scenarios such as residential buildings, apartments, office buildings, shopping malls, factories, warehouses, schools, and old community renovations.
