China factory price sandwich sheet
Sandwich panel is made of two layer modular metal sheet (or other material sheet) and foaming core material. It usually uses plywood board, fiber board and metal sheet as the surface layer. Core materials include light wood, rubber, acetate fiber, plastic, paper or cloth impregnated with resin (or not impregnated) and metal honeycomb structural materials. Its advantages mainly include,
- Strength of plywood board is high.
- Core material is cheap with large quantity using so that the cost is low.
- Reasonable selection and matching of surface and core materials can effectively meet the performance requirements of pre-designed sheets.
For example, metal cladding is selected to improve the fire resistance and water resistance of the sheet, and decorative sheet or plastic sheet is selected as the surface layer to improve its decorative effect. And its characteristics are as the following,
- Light weight, less than 24kg per square meter, can fully reduce the structure cost.
- The characteristics of fast installation, light self-weight, plug, installation and free cutting determine the simplicity of installation, which can improve efficiency and save construction period.
- For fire protection, the surface material and thermal insulation material of color sheet composite core sheet are non-combustible materials, which can meet the requirements of fire protection specifications.
- Fire resistant, color steel plate treated with special coating shall be kept fresh for 10-15 years, and then coated with anti-corrosion paint per ten years, the service life can be reached more than 35 years.
- Beautiful, clear lines of profiled steel sheet can meet the needs of buildings of any style with dozens of colors.
- Thermal insulation: common thermal insulation materials include rock wool, glass fiber wool, polystyrene, polyurethane, etc., with low thermal conductivity and good thermal insulation effect.
- Environmental protection and noise prevention. The sound insulation strength of the composite board can reach 40-50 decibels. It is a very effective sound insulation material.
- Strong plasticity, use high strength steel sheet as base material.Profiled steel sheet can be cut at will to meet the needs of special design requirement.
