Roofing Sandwich panel systems offer integrated thermal insulation and waterproofing, featuring a robust structure and excellent waterproof, wind-resistant, heat-insulating, and sound-absorbing properties. They are also highly adaptable in appearance and widely used in industrial buildings, public venues, transportation, and commercial buildings.
Metal-faced sandwich roofing panels use profiled steel sheets as the top and bottom layers. The core material can be polyurethane, foam, rock wool (PU side sealing), or glass wool (PU side sealing). Edge filling further enhances the panel's strength. They provide reliable airtightness and watertightness, excellent thermal insulation, and quick installation, fulfilling the design goals of energy-efficient roofs.
Four ribs polyurethane roofing sandwich panels are a high-performance composite roofing material widely used in modern industrial and public buildings. It combines excellent structural performance, top-notch thermal insulation, efficient installation, and aesthetic and durable characteristics. We can have instructions to be offered for each different project, as per customers' requirement. If customers have special requirements for on-site guides, we can also have our people to go to customers' project sites to support your installation.
If the project budget is sufficient, and an outstanding appearance and long-lasting waterproofing are pursued, the concealed nail fixing system should be the first choice. If the project's primary goals are cost control and rapid delivery, and the aesthetic requirements are average, then visible nail fixation is an economical and practical reliable choice.

Buildings need to deliver more than ever before. Through innovation in advanced materials & digitalisation, we’re helping you create buildings that tackle the sustainability challenges of the future. We invite you to explore our global case studies and product roadmap, and to work together to practice sustainable building.
Our Group has built a highly automated, high-precision, and highly stable production system by introducing fully automated continuous production lines such as the Italian Puma line and the German KraussMaffei line. The company has an annual production capacity of 5 million square meters, covering a variety of sandwich panel products including PU/PIR/EPS/rock wool/glass wool. It can respond to customer orders efficiently and effectively, providing one-stop service to meet the personalized construction needs of various enclosure systems.
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 key areas including: 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. Six major manufacturing bases are established globally, operating 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.
Our 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.
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.
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.
