Product Description

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.

Product Description
Aluminum Alloy Insulated PU Panel
Aluminum Alloy Insulated PU Panel (Great Panel)
Our Aluminum Insulated PU Panel is an integrated building panel featuring a high-strength aluminum alloy surface layer cold-rolled into a Great Wall pattern, with a high-efficiency insulating core injected inside. Compared to traditional color-coated steel sandwich panels, it fundamentally resolves steel's susceptibility to corrosion while retaining its superior thermal insulation and ease of installation. Although the initial investment is higher, its exceptionally long service life, minimal maintenance costs, and outstanding overall performance deliver significant economic advantages over its entire lifecycle. This makes it an ideal building envelope solution for those seeking high quality, durability, and safety.
Snap Fit and Hidden Screws
Snap Fit + Hidden Screws
Snap-fit + Hidden screws Installation System combines efficiency with aesthetics. The snap-fit mechanism enables rapid assembly and accommodates thermal expansion and contraction, while concealed screws provide secure anchoring. With no exposed nails, it maintains a seamless facade appearance. Offering easy installation and maintenance, it delivers superior wind resistance and waterproofing performance, making it the preferred solution for high-standard buildings.

Product Highlights
Thermal Insulation
Thermal Insulation
Polyurethane core material features a low thermal conductivity (0.022–0.024 W/(m·K)), delivering over twice the insulation efficiency of EPS foam. It enables ultra-thin insulation designs, conserving space while reducing energy consumption and operational costs. It effectively prevents condensation and thermal bridges, making it suitable for cold storage facilities, temperature-controlled workshops, and similar applications.
Lightweight and High Strength
Lightweight and High-Strength
The panel's self-weight is only one-thirtieth that of traditional brick-concrete structures, significantly reducing structural loads and foundation costs. Its “sandwich” composite structure provides high flexural and compressive strength, enabling it to withstand strong winds and heavy snow loads. The high-pressure continuous foaming process achieves 100% core material filling and secure bonding, ensuring stable overall load-bearing performance.
Fire Resistance
Fire Resistance
The polyurethane core undergoes flame-retardant treatment to achieve Class B1 fire resistance standards, self-extinguishing upon removal from flames. Through technological upgrades, it can also meet Class A non-combustible requirements. The aluminum alloy panel itself is a non-combustible material, forming the first line of fire defense to comprehensively safeguard building safety.
Weather Resistance
Weather Resistance and Durability
Featuring PVDF fluorocarbon-coated aluminum panels, it resists UV radiation and corrosion, guaranteeing no fading for over 25 years. The high-closed-cell polyurethane core, combined with professional sealing, prevents water penetration and moisture. The entire system is designed for maintenance-free operation, requiring no special upkeep after installation.
Efficient Installation
Efficient Installation
Factory prefabrication and dry-construction assembly methods eliminate weather constraints, reducing construction time by over 70%. The product integrates enclosure, insulation, fireproofing, waterproofing, and decoration into one unit for simplified installation. Featuring diverse aluminum panel finishes, it offers aesthetic appeal, environmental sustainability, and recyclability, meeting green building standards.
