PU (Polyurethane) Sandwich Panels Description
A The sandwich panel is a sophisticated structure crafted from three layers of materials: a low-density core is sandwiched between two robust steel skin layers. This innovative setup delivers remarkable mechanical performance while maintaining minimal weight. The exceptional rigidity of this sandwich panel is achieved through the synergy of its components, especially under flexural load applied to the panel. The core adeptly handles shear loads, maintaining a strategic distance between the skins, which are responsible for absorbing in-plane stresses-one in tension, the other in compression. For comprehensive insights into sandwich panel structures, various available core types, and their potential for weight savings, please consult the following reference.
1) Surface Sheet:
The surface sheet of our PUR or PIR (Polyurethane) sandwich panels typically consists of PPGI or PPGL steel color-coated sheets. PPGI refers to prepainted galvanized coated steel, while PPGL denotes prepainted Al-Zn coated steel. For coating types, you can select from options such as PE, PVDF, HDP, SMP, etc. Our strategic partners include notable brands like Bluescope, Bao-steel, Shougang steel, Guanzhou steel, Yieh Phui steel, and Xinyu steel, ensuring superior quality and durability.
2) Polyurethane Core Material
Our Fireproof Waterproof polyurethane core material is sourced from industry-leading strategic partners such as Huntsman and WANHUA, ensuring the highest standards of quality and performance.
The Polyurethane Sandwich Panel, also known as PU Sandwich Panel, features a top and bottom sheet made from galvanized and pre-painted steel, encasing a core of five-component polyurethane glue. This structure is formed through a meticulous process of heating, foaming, and laminating. Polyurethane is renowned for its superior heat and sound insulation properties, minimizing heat transfer due to temperature differentials and optimizing the efficiency of freezing and refrigeration systems. As a cutting-edge heat insulation material, it offers reduced construction costs. Available in a diverse range of varieties and specifications, these panels cater to the unique demands of various sites and projects.
PU Sandwich Panel, or Polyurethane Sandwich Panel, comprises two layers of weather-resistant colored steel sheets, with hard polyurethane forms injected between them. These panels are ideal for roofing and wall applications in large-scale structures like factories, storage facilities, exhibition halls, gymnasiums, cold storage units, and purification workshops. They are distinguished by their excellent heat insulation, load-bearing capacity, weather resistance, vibrant color options, and attractive appearance.
Polyurethane foam is expertly sandwiched between the dual outer skins, earning the name PU sandwich panels. We specialize in manufacturing reliable PU sandwich panels in a wide array of specifications. These panels are available with zinc-coated, galvanized steel, embossed aluminum, stainless steel, or other material sheets, offering versatility and robustness.
Our company currently offers a diverse range of PU sandwich panels, tailored to meet the varied requirements of customers and markets alike. We are committed to providing solutions that align with the unique demands and expectations of our clientele.
