Polyurethane sandwich wall panels are high-performance building envelope materials. They are formed through a continuous molding process, combining two metal panels (or non-metallic panels) with a polyurethane rigid foam insulation layer. They combine thermal insulation, decoration, and structural benefits, mainly used in industrial logistics buildings, cold chain, public commercial facilities, agricultural and animal husbandry buildings, etc.
The manufacturer has successively introduced Italy's fully automatic continuous production line Puma Line and Germany's KraussMaffei Line, which have the characteristics of high automation, high control accuracy, and high safety and stability. It can produce various types of continuous self foaming PUR/PIR polyurethane color steel sandwich panels of 5 million square meters per year, thereby completing customer orders with high quality and efficiency, meeting the personalized enclosure system construction needs of different customers in a one-stop manner.

PU/PIR sandwiches offer excellent heat preservation, insulation, and soundproofing. Additionally, the core material is flame retardant and meets safety standards. With the joint action of the upper and lower panels and polyisocyanurate, the system delivers high strength and rigidity. The lower panel is smooth and flat with clear lines, which increases the aesthetics and flatness of the room. It is a new type of building material with easy installation, short construction period and beautiful appearance.
The thermal conductivity of polyurethane rigid foam is typically between 0.018 and 0.024 W/(m·K). This is significantly lower than most common insulation materials. Thinner sheets can achieve the same or even better insulation performance.
PU sandwich panels can reduce building energy consumption, significantly reduce air conditioning and heating operating costs, bringing long-term economic benefits, and complying with green building requirements.
The lightweight nature of these panels reduces building loads, while their compressive and bending resistance allow them to serve as both load-bearing and envelope structures with excellent durability.
The panels are prefabricated in the factory, ensuring precise dimensions. Tongue-and-groove plug-in installation processes significantly shorten construction time and save labor and machinery costs.
By adding flame retardants, polyurethane sandwich panels can achieve Class B1 (flammable) or Class B2 (combustible) fire protection standards, effectively slowing the spread of fire.
Rigid polyurethane foam features a high closed-cell ratio (≥90%). These pores are not interconnected, providing excellent waterproof and moisture-proof properties, critical for cold storage environments.

Founded in 2011, we are a national high-tech enterprise specializing in the research, development, manufacturing, and service of green, energy-saving, and environmentally friendly new materials. Our main business focuses on the following key areas: Cold storage and industrial insulation materials, Integrated decorative and insulation panels, and other mainstream international green, energy-saving, and environmentally friendly new materials.
Our sandwich panels are manufactured on a fully continuous, integrated production line, enabling rapid and efficient conversion from roll material to finished product. Precise control of dimensions, formulation, and processes via a CNC system ensures high consistency across batches. The surface layer and core material are laminated and firmly bonded online in a single process, forming a high-performance sandwich structure. The entire production process is traceable, guaranteeing controllable quality.
The company employs nearly 500 staff members, including 50 R&D personnel. The organization has established six major manufacturing bases and operates 10 domestic business centers and 6 overseas business centers. It also features a provincial-level technology center, a provincial engineering technology center, and two standard laboratories.
The metal-faced sandwich panels have passed comprehensive testing by the International Building Materials Quality Supervision and Inspection Center. The rock wool core material meets Class A non-combustible standards, and its thermal conductivity exceeds national standards. The products are manufactured in strict accordance with the ISO 9001 quality management system and have obtained European and American green building materials product certifications. Relevant fire resistance, wind pressure resistance, and project application examples are available upon request, forming a complete quality certification system from compliance and core performance to environmental safety.
As a professional manufacturer of sandwich panels, we significantly reduce resource consumption throughout the entire lifecycle of buildings while ensuring building safety and energy efficiency through the research and application of high-performance building materials, thus practicing environmental protection principles. To date, we have provided reliable roofing and wall system solutions to over 17,000 customers worldwide, covering industrial, logistics, public buildings, and overseas projects. This trust testifies to our brand value.
Our sandwich composite panel selects high-quality raw materials combined with mature panel type and scientific installation details design, to create a multi-purpose sandwich panel that features outstanding fire resistance, heat preservation, watertightness, weatherability, wind resistance, pressure resistance, as well as sound absorption and insulation, so as to meet the personalized requirements of the client.
