Product Description
A Sandwich panels are a marvel of modern construction, ingeniously crafted from three layers: a lightweight core nestled between two durable steel skins. This sophisticated design ensures outstanding mechanical performance with minimal weight. The exceptional rigidity of sandwich panels stems from the synergy between its components under flexural stress: the core deftly absorbs shear loads while maintaining distance between the skins, which respectively handle tension and compression forces. For deeper insights into the structure, core varieties, and weight-saving capabilities of sandwich panels, please refer to the comprehensive reference provided.
1) Surface Sheet:
Typically, the surface sheet of our PUR or PIR sandwich panels is crafted from PPGI or PPGL steel color-coated sheets. PPGI stands for prepainted galvanized coated steel, while PPGL represents prepainted Al-Zn coated steel. Choose from diverse coating types such as PE, PVDF, HDP, and SMP. Our esteemed partners include industry leaders like Bluescope, Bao-steel, Shougang steel, Guanzhou steel, Yieh Phui steel, and Xinyu steel, ensuring top-notch quality and reliability.
2) Polyurethane Core Material
Our premium polyurethane core materials are sourced from our trusted strategic partners such as Huntsman and WANHUA, ensuring superior insulation and performance.
The Polyurethane Sandwich Panel, also known as PU Sandwich Panel, is composed of galvanized and pre-painted steel sheets on both sides, with a robust core of 5-component polyurethane glue. This advanced structure is crafted through a meticulous process of heating, foaming, and laminating, making polyurethane an unparalleled choice for heat and sound insulation. It minimizes heat transfer due to temperature disparities, optimizing efficiency in freezing and refrigeration systems. As a groundbreaking insulation material, it offers reduced construction costs and comes in diverse varieties and specifications to suit various project and site requirements.
The PU Sandwich Panel, or Polyurethane Sandwich Panel, features a unique composition of two layers of weather-resistant colored steel sheets, with hard polyurethane foam expertly injected between them. This design is perfect for a range of applications including large factory buildings, storage facilities, exhibition halls, gyms, cold storage, and clean rooms. It boasts exceptional heat insulation, load-bearing capacity, weather resistance, and comes in a rich array of colors and an aesthetically pleasing appearance.
Our PU sandwich panels are renowned for embedding polyurethane foam between two outer skins, hence the name PU sandwich panels. As a trusted manufacturer, we offer these panels in various specifications to meet diverse customer needs. These two layers can be profiled in zinc-coated, galvanized steel, embossed aluminum, stainless steel, or other materials, ensuring robust performance and versatility.
Currently, our company offers a diverse range of PU sandwich panels, each designed to cater to the unique demands of our customers and various market needs.
