1. Primarily, visually inspect the surface for平整ness and the thickness to ensure it meets specifications. Typically, the base beam wire should be 3mm or more, the steel reinforcement protective layer should be 20mm or more, and the moisture absorption rate should be less than 0.1%.
2. The steel frame light exterior wall panel is made of a composite core board using porc modified material concrete expanded perlite, making it lightweight and flexible. It features a surface that can be magnetically adhered to; however, if it does adhere, it is not due to magnetic attraction, as it is constructed from C steel, which is not magnetic.
3. Based on the expert's summarized features such as moisture-proof and sound insulation, these aspects are all detectable. After the inspection, we will assess if they comply with the standards. The average sound insulation should be over 40 dB, and the material should not crack or release harmful gases when exposed to fire, featuring a moisture-proof coating.
Product Composition:
The composite product, known as polyurethane foam concrete composite board or, alternatively, as steel structure thermal insulation sandwich panel, is created by the rational connection of steel outer frames with embedded truss structures, filled with high-strength material, and merging the upper and lower layers, resulting in a component that combines lightweight, load-bearing, and thermal insulation properties.
2. Key Core Board:
Comprised of high-intensity materials, our lightweight aggregate concrete boasts an expansion coefficient of 6-8 times, an internal muscle rate exceeding 95%, and a density of 280-210 kg/m³. Our current lightweight aggregate concrete products feature a lower thermal conductivity, λ=0.067-0.074 W/m.K, addressing the traditional material's drawbacks such as flammability, permeability, harmfulness, and short lifespan.
3. Furniture Frame Boards
Selected specialized hot-dipped galvanized iron edge ribs.
4. Furniture Panel Lifespan:
The galvanized steel frame and high-strength core board have a lifespan equivalent to their usage period, lasting fifty years without replacement. Over 95% of the materials can be recycled once the product's lifespan ends. Moreover, the production process is highly environmentally friendly.
