A New Composite Panel Arrives: Eight Major Advantages Leading Innovation in the Building Roofing System Industry

Hark Metal Curtain Wall, Creating a Modern Building That Stands the Test of Time

Amidst the continuous upgrade of building materials, a new composite panel has emerged, combining multiple advantages—lightweight, high strength, factory prefabrication, and cost-savings—with exceptional performance. It is redefining the standard for building roofing systems, providing the construction industry with a new, efficient, economical, and reliable solution.

1. Lightweight and High Strength, Excellent Wind and Pressure Resistance

This composite panel, constructed from a steel + rock wool composite, weighs only 15-30 kg/m2 per square meter, significantly reducing building loads while achieving a wind-uplift resistance test of up to 7700 Pa, making it capable of withstanding extreme wind conditions and providing a strong "safety line" for building roofs. It is particularly suitable for construction projects with large spans and high wind pressure areas. 

2. Factory Prefabrication, Elevating Assembly Efficiency

Breaking beyond traditional on-site operations, composite panels are 100% factory-prefabricated, combining both sheet and coil materials. Using prefabricated roof construction, they are produced to exact lengths and quantities, ensuring consistent product quality from the start. This significantly shortens on-site construction cycles, accelerating and increasing project efficiency.

3. Thermoplastic Coil Enhancement, Leading the Industry in Durability

Composite panels utilize an innovative process where waterproofing coils are thermoplastically pre-coated onto steel plates. This innovative process offers exceptional durability with a warranty period of over 25-30 years. The peel strength reaches 4N/mm, significantly exceeding the bond strength between steel and rock wool, fundamentally resolving the pain point of short-lived roof waterproofing.

4. Steel and Material Savings, Optimizing Space and Cost

In terms of structural design, the purlin spacing of the composite panels can be precisely calculated based on the project, typically exceeding 2000mm. This significantly reduces steel usage, achieving both cost-effective steel and material savings and improved space utilization. 5. Simple Construction, Simplified Layers

Abandoning the complex structure of traditional roofing systems, this composite panel system features a streamlined structure, achieving all functions with just one layer. It eliminates the need for redundant components such as baseboards, non-woven fabrics, vapor barriers, and additional keels, simplifying roof structural design and construction.

6. Efficient Construction, Immediate Cost Savings

Thanks to industrialized prefabrication and simplified construction, composite panel construction efficiency is significantly improved, saving over 50% in construction costs while shortening construction schedules, providing strong support for achieving cost reduction and efficiency gains in construction projects.

7. Cost Savings, Significant Overall Benefits

Compared to traditional roofing systems, this composite panel achieves comprehensive optimization in steel usage, materials, construction, and construction schedules, reducing overall costs by 10-20%, making it a cost-effective tool for builders. 8. Trinity: Diverse Applications Expand Infinite Possibilities

Composite panels are not only the core material for building roofs, but also offer a smooth, high-strength construction surface with a built-in waterproof layer. Combined with a non-penetrating welded base, and with the addition of a photovoltaic or decorative layer, they enable integrated applications of building, waterproofing, and photovoltaics, opening up new avenues for green building and photovoltaic-building projects.

From industrial plants and warehouses to large public buildings, this new composite panel, with its eight key advantages, is becoming a preferred solution for building roofing systems. Going forward, it will continue to drive industry change through technological innovation, bringing efficient, economical, and sustainable value to more construction projects. We sincerely invite all architectural professionals to explore this new product and embark on a journey of innovation in building roofing systems together!
