Product Description
A sandwich panel is an ingenious construction consisting of three layers: a lightweight core material nestled between two thin but sturdy steel skin layers. This innovative design offers superb mechanical performance while keeping the weight to a bare minimum. The exceptional rigidity of a sandwich panel is attributed to the harmonious interaction of its components under a flexural load. The core handles shear loads and creates spacing between the skins, which experience in-plane stresses; one in tension, the other in compression. For comprehensive insights into sandwich panel structures, various core types, and their potential for weight savings, please refer to the following reference.
1) Surface sheet:
Typically, the surface sheet of PUR or PIR sandwich panels features PPGI or PPGL steel color-coated sheets. PPGI denotes pre-painted galvanized steel, while PPGL refers to pre-painted Al-Zn coated steel. For coating preferences, you may opt for PE, PVDF, HDP, SMP, etc. Our esteemed strategic partners include Bluescope, Bao-steel, Shougang steel, Guanzhou steel, Yieh Phui steel, Xinyu steel, and more.
2) Polyurethane core material
Our polyurethane core materials are sourced through strategic collaborations with industry leaders such as Huntsman and WANHUA.
Our company currently offers a diverse range of PU sandwich panels to satisfy the unique requirements of varied customers and markets.
We have three joint ways for PU sandwich wall panels;
The left image illustrates two types of concealed joint wall panels, available with or without a 20mm decorative seam,
which are increasingly preferred for exterior walls of steel buildings.
On the right, the tongue-and-groove joint method is showcased, which is widely used for cold rooms.
