Product Description
A sandwich panel is an ingenious structural design featuring a tri-layered composition. At its core lies a low-density material sandwiched between two robust, thin steel skins. This strategic arrangement grants the sandwich panel exceptional mechanical properties while maintaining a lightweight profile. The remarkable rigidity of the panel is a result of the harmonized interaction of its components when subjected to flexural loads. Here, the core adeptly manages shear forces and maintains an optimal distance between the skins, which tackle in-plane stresses; one skin handles tension while the other manages compression. For further insights into the structural dynamics, diverse core types, and the potential weight savings offered by sandwich panels, please refer to the detailed specifications available.
1) Surface sheet:
Typically, the surface sheet of our premium PUR or PIR sandwich panels is crafted from high-quality PPGI or PPGL color-coated steel sheets. PPGI stands for pre-painted galvanized coated steel, while PPGL represents pre-painted Al-Zn coated steel. You have the flexibility to select from a variety of coatings such as PE, PVDF, HDP, SMP, etc. We proudly collaborate with esteemed brands like Bluescope, Bao-steel, Shougang steel, Guanzhou steel, Yieh Phui steel, Xinyu steel, ensuring unmatched quality and durability.
2) Polyurethane core material
Our trusted brands for polyurethane core materials include 
Huntsman, WANHUA, among others.
The Polyurethane Sandwich Panel, often referred to as the PU Sandwich Panel, showcases a top and bottom layer of galvanized and pre-painted steel sheets, enveloping a core of 5-component polyurethane glue. This advanced panel is meticulously crafted through a process of heating, foaming, and laminating. Renowned for its superior thermal and acoustic insulation properties, polyurethane significantly mitigates heat transfer between internal and external environments, optimizing the efficiency of refrigeration and freezing systems. This cutting-edge insulation solution not only lowers construction costs but also offers a diverse range of varieties and specifications tailored to various project requirements.
The PU Sandwich panel is an architectural marvel comprised of two layers of weather-resistant colored steel sheets with a dense polyurethane core injected between them. Designed for versatility, these panels are ideal for the roofing and walls of expansive structures such as factories, warehouses, exhibition centers, sports arenas, cold storage facilities, and clean rooms. They offer remarkable benefits including excellent thermal insulation, load-bearing capacity, weatherproofing, vibrant colors, and an aesthetically pleasing finish.
Named for its construction, the Polyurethane foam in PU sandwich panels is securely ensconced between two protective outer skins. We specialize in manufacturing dependable PU sandwich panels available in an array of specifications. These layers can be profiled with zinc-coated, galvanized steel, embossed aluminum, stainless steel, or other durable materials, ensuring robust performance.
Currently, our company offers a diverse array of PU sandwich panels, each designed to cater to the varying needs of our global clientele and market demands.
Depending on the joint methods employed, these panels are categorized as demonstrated in the accompanying visuals.

Unparalleled Product Benefits:
Our versatile sandwich panels are perfectly tailored for a multitude of applications including expansive industrial plants, efficient warehouses, bustling supermarkets, modern hospitals, dynamic stadiums, high-performance cold storage facilities, and innovative activity rooms. They expertly suit the construction of additional layers on buildings, pristine clean workshops, and vital heat insulation fire places. In vibrant urban settings, they seamlessly integrate into commercial housings such as exhibition halls, shopping centers, and sophisticated office spaces. Moreover, they are ideal for temporary constructions like on-site offices and warehouses, ensuring convenience and functionality.
1. Superior Fireproof and Flame-Retardant Attributes. With the incorporation of advanced flame retardants, our PU board emerges as a refractory self-extinguishing marvel. It is designed to effectively halt the spread of fire, transforming into a non-flammable solution especially when subjected to comprehensive fire prevention treatments.
2. Remarkable Waterproof CapabilitiesOur PU sandwich board boasts an impressively low water absorption rate and outstanding water vapor permeability resistance. Its foam pores exist in an independent state, ensuring minimal communication, with an exceptional closed cell rate exceeding 90%. This results in a dense micro porous foam material, creating a more compact surface that significantly reduces water permeability, classifying it as a superior hydrophobic material.
3. Exceptional Weather ResistanceEngineered to endure the harshest local climates and their fluctuations, whether it's extreme heat or chilling cold, our polyurethane PU board maintains its integrity. It safeguards the exterior wall insulation system from damage or deformation, ultimately reducing project complexity, cost, and construction time, making it a cost-effective, time-saving choice for your building needs.
