Sandwich board products are formed by two layers of metal panels (or other materials panel), and directly in the middle of the panel foam, aging molding polymer insulation core composition. These sandwich panels are easy to install, lightweight and efficient. Filling system is also used closed-cell molecular structure, can prevent condensation of water vapor. The formation of the outer steel plate fully takes into account the structural and strength requirements, taking into account the appearance, the inner layer is formed into a flat plate to meet various needs.
Metal panel and non-metallic panel two. Metallic panels are easy to machine and can be made in a variety of shapes, but in some applications non-metallic panels have a role that metal panels can not, such as corrosion and impact resistance.
Sandwich board characteristics
1, light weight less than 24kg per square meter, you can fully reduce the cost of the structure.
2, fast and light weight installation, docking, installation and cutting characteristics can be freely decided to install its simple, can improve efficiency and save time.
3, fire prevention, Caigang compound with the core board material and insulation materials for the non-burning or flame retardant materials, to meet fire safety requirements.
4, fire-resistant, the special coating of color steel plate up to 10-15 years, after every ten years after spraying anti-corrosion coatings, plate life of 35 years.
5, beautiful, pressure-type steel plate clear lines up to dozens of colors, with any style of building needs.
6, thermal insulation Common insulation materials are: rock wool, glass fiber cotton, polystyrene, polyurethane, etc., low thermal conductivity, with good thermal insulation effect.
7, environmental noise, composite panels noise intensity of up to 40-50 dB, is a very effective noise insulation material.
8, strong plasticity can be cut any type of steel, enough to meet the special needs of the design.
9, high-strength high-strength steel as the substrate, the tensile strength 5600 (kg / cm2), coupled with the most advanced design and roll forming, with excellent structural characteristics.
