30 YEARS OF EXPERIENCE IN ROOF PANELS: 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, EPS 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.
The photovoltaic (PV) energy-saving roof system is an integrated solution customized for large industrial and commercial buildings, deeply integrating three major functions: high-efficiency thermal insulation, building energy conservation, and clean energy utilization. The system uses a 360-degree interlocking structure of metal/rock wool/polyurethane energy-saving panels as its core, balancing load-bearing and thermal insulation requirements. It achieves rapid and secure installation of solar panels through snap-on fasteners, forming a reliable integrated PV energy-saving roof system. This product is particularly suitable for industrial and commercial scenarios seeking to reduce operating energy consumption and practice sustainable development, making it an ideal roofing choice for achieving economic, environmental, and long-term benefits.
The 360° standing seam roof panel system is a high-end metal roofing system that features precise mechanical interlocking, allows for free expansion and contraction, and offers structural waterproofing and outstanding wind resistance. It represents the advanced level of modern large-span building roofing technology. Although the initial investment is relatively high, it has become the first choice for large landmark buildings due to its extremely long service life, very low maintenance cost and outstanding reliability.

Optional insulation core materials include polyurethane and rock wool. For ultimate insulation performance and structural efficiency, choose polyurethane; for top-notch fire safety and long-term stability, choose rock wool.
The 360° standing seam roof panel structure provides excellent wind uplift resistance, corrosion resistance, and waterproofing. Its high-strength, weather-resistant materials guarantee a service life of over 25 years, ensuring a safe, stable building envelope and long-term reliable operation.
Initial investment is integrated and saves on bracket, counterweight, and some installation costs. Efficient standardized installation processes significantly reduce construction time and labor costs. As an integrated roofing system with no leakage risks, it eliminates bracket corrosion and loosening issues, significantly reducing subsequent maintenance needs and costs.
The photovoltaic roof sandwich panel integrates power generation and insulation, simultaneously achieving clean energy production and building energy savings. Material integration reduces resource consumption, comprehensively promoting green and sustainable building development.
Photovoltaic roof sandwich panels seamlessly integrate photovoltaic modules with the building roof, resulting in a simple, unified, and technologically advanced appearance. Customized designs allow for flexible adjustments to photovoltaic arrangement, color, and light transmittance to meet individual architectural aesthetic needs.
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.
