color steel sandwich panel

Brief introduction of products
Color steel sandwich panel is a kind of composite material with interior and exterior surfaces of color steel sheets, and in between, polystyrene, polyurethane or rock wool or other core materials. The surface sheets together with the core materials in between, pass through the automatic compound and molding machine; the steel sheets are coated with adhesive, and thin-wall channel steel is built into the panels on both sides; pressure is applied to the surface panels and core materials; the sandwich panel is thus formed.

Sandwich panels, by types of core materials, fall into the following four categories: polystyrene sandwich panel, rock wool sandwich panel polyurethane sandwich panel, phenol aldehyde sandwich panel, etc.

Scope of application
Color steel sandwich panel is a kind of new multi-functional building material. It is featured with heat preservation, heat insulation, sound insulation, light weight, waterproofing, seismic protection, decoration, etc., and widely used as the non-bearing walls, roofs and ceilings for industrial and civil buildings, as well as the bearing walls for  single-storey houses. In particular, it is mainly used as partitions and ceilings in the cleanrooms for the electronic, semi-conductor, pharmaceutical, food facilities.

Biological and food industries.
Specifications and performance of color steel sandwich panel:
1. Yijing color steel sandwich panels adopt the up-to-date groove-and-wedged connection, which is characterized with easy installation, time saving, material saving, good flushness, and high strength. They are especially suitable for the ceiling systems.
2. Thickness (mm): 50, 75 and 100;
3. Length (mm): Since the boards are produced by continuous molding, the length of the boards can be decided by the users.
4. Breadth (mm): 1150
