Flexibility and Strength Combined: Lightweight Integrated TPO 

Flexible Roofing Leading the New Trend in Architecture

With advancements in technology and the continuous development of the industry, society has set higher standards for environmental protection and safety. Modern architecture places increasing importance on the materials used for building enclosures. Traditional roofing systems often use color-coated steel tiles combined with BAPV (Building-integrated Photovoltaics) to achieve the roof + photovoltaic functionality. Over time, however, some issues and hidden risks have been discovered. For instance, after prolonged use, the seams in color-coated steel tiles can leak, jeopardizing the building's waterproof performance. The newly released 2023 waterproof regulations have introduced mandatory requirements for membrane waterproofing in metal roofing.

To address these challenges, traditional metal roofing suppliers began searching for more innovative products that meet the high safety, durability, and cost-effectiveness standards of building roofing systems. This led to the development of Hongxinyuan's self-developed Prefabricated Integrated TPO Flexible Roofing System.

01 TPO Flexible Roofing System Structure

The TPO Prefabricated Integrated Flexible Roofing System utilizes TPO membrane and corrugated steel sheets as the top layer, with high-strength, water-repellent rock wool as the core material. These components are bonded using a high-strength adhesive and then formed into self-supporting composite panels through advanced continuous-line heat-pressing technology in the factory.

Compared to traditional flexible roofing solutions, this system integrates the waterproof membrane, insulation layer, and deck steel base layer that were previously installed in separate layers. The TPO flexible roofing system incorporates the advantages of multiple materials, reflecting the design philosophy of "blending the benefits of both rigidity and flexibility for a beautiful, harmonious structure."

02 Advantages of the TPO Flexible Roofing System

01 Lightweight Design, Innovative Space

Compared to traditional mechanically fixed single-layer roofing systems, Hongxinyuan's TPO Flexible Roofing System uses a combination of high-closed-cell polyurethane edging and high-strength rock wool as the core material, along with high-quality galvanized steel for the panels. This reduces the overall weight of the roof system, providing more load-bearing space for distributed photovoltaic power stations on the roof, and offering greater flexibility to meet various needs.

02 Fast Installation, Easy Maintenance

The TPO flexible roofing system is prefabricated in the factory, allowing for quick installation on-site, reducing construction time by more than 50%. It is adaptable to various building shapes and structures, and can be installed without seams, reducing the risk of leaks. The system complies with the new waterproof regulations, has low maintenance costs, and only requires regular cleaning and inspection, thus reducing maintenance expenses.

03 Integrated Solution

The TPO flexible roofing system integrates waterproofing and insulation, and can also incorporate distributed photovoltaic panels. It provides a comprehensive building enclosure solution that offers full protection for your building. Its stable and secure design ensures the building remains robust and safe in various environments.

04 Green and Eco-Friendly

TPO (Thermoplastic Polyolefin Waterproof Membrane) boasts high tensile strength, a smooth surface, low-temperature toughness, and excellent resistance to heat aging. It is ideal for use with lightweight photovoltaic modules. In the context of the "dual carbon" goals, this product meets the demand for green building roofs and complies with the first-level waterproof standard of the new national regulations. It is an innovative and environmentally friendly roofing material option.

03 Applications of the TPO Flexible Roofing System

With the continuous innovation in roofing waterproofing technology in China, the use of new waterproof materials in distributed photovoltaic roofing systems has become increasingly widespread. In addition to common roofing types like color-coated steel tiles, TPO flexible roofing has been widely recognized by many owners and is extensively used in large roofing waterproofing and photovoltaic projects in industries such as industrial factories, data centers, logistics, airports, and high-end domestic manufacturing.

Guided by the principles of green development, Hongxinyuan is committed to continuously creating more efficient and innovative products that meet contemporary building needs. In the context of the "dual carbon" goals, the company focuses on the building enclosure field, promoting intelligent and green architecture, and achieving sustainable development for buildings.
