As of 2026, it is basically a common sense in industrial sectors that to find an efficient, economical and durable construction material. Most construction companies and contracting companies tend not to use old products such as iron roofs that have to be replaced all the time because of rust and corrosion. In fact, construction materials with high technological level and long duration will be inevitable for industrial constructions in the future.
JieLi is one of the pioneers in the development of PVC and UPVC roofing technologies. Since 1994, Jieli Roof Tile has become the largest UPVC Roof Sheets, Composite Roof Tiles, Glass Fiber Reinforced Roof Sheets manufacture in China. By having an authorized roof sheet test lab from the Government, which is also accredited by CMA, our materials are tested and checked throughly from the primary materials to the final products. Instead of looking at the first low cost of materials, our customers enjoy durable structures, which would safeguard their industrial buildings in the toughest conditions.
Corrosion is a chronic problem at many industrial plants – petroleum refineries, chemical plants and warehouses located near the ocean. Often made of common metal substances, their roofs last only two to three years in highly-corrosive, highly-polluted or highly-salt-laden atmospheres. In an industrial environment, sulfur and nitrogen compounds are dissolved in the ambient air together with water vapor to form acid rain, a highly-corrosive compound, which eats its way into all metals, causing pitting corrosion that renders the structure inoperative and which requires large replacement costs.
This year 2026 has also experienced the extremity of temperature changes which are very hard on building materials. Metal sheets, for example, tend to spread heat very rapidly, which means that, in order to avoid thermal expansions and thus big consumptions, a permanent watch has to be kept. In general, the building contractors are searching for new products, able to bear the natural weathering, without requiring a permanent application of protective treatments. It has come then the lightweight UPVC roofing as the answer to the “do it once and last” building idea which has to resist to many years of chemical and weathering attacks.
When evaluating materials for a 2026 industrial project, the longevity of the roof is the most critical metric. We have engineered our roofing solutions to offer a service life that reaches three to five times that of traditional color steel tiles. Unlike steel, which relies on a thin layer of paint for protection, our materials are inherently anti-corrosion and rust-free throughout their entire structure. This fundamental difference eliminates the risk of hidden oxidation and delamination.
One major pain point for Contractors is the weight of traditional clay or heavy metal sheets. Our lightweight UPVC roofing allows for faster installation and reduces the structural load on the building frame. Despite being lighter, these sheets provide superior performance in several key areas:
The success of our specialized roofing lies in its sophisticated structural composition. We utilize Triple-Layer Co-extrusion Technology combined with a specialized Fiberglass Layer to create a cohesive, multi-functional product. These sheets have four useful layers built in, each designed to tackle a specific environmental threat.
The top layer is treated with ASA (Acrylonitrile Styrene Acrylate) to fight UV harm and keep bright colors. This acrylic resin layer protects the roof from color fading for 8 to 10 years, whereas traditional painted steel often fades within a few months. The second layer is UPVC, which offers outstanding strength, impact resistance, heat insulation, and sound insulation performance. The third layer is a Fiberglass reinforcing layer, which enhances high-temperature resistance, strength, impact resistance, tensile resistance, and load-bearing performance. Finally, the bottom layer is UPVC, which is corrosion-resistant, moisture-proof, and enhances structural stability. This four-layer approach ensures that every sheet acts as a complete protective system for the building.
A standout feature in our industrial catalog is the UPVC Roofing Sheet T1088. This product integrates our national invention patent technology, which incorporates a glass fiber reinforcing layer inside the UPVC structure. Contractors often refer to this as “soft steel reinforcement” because it provides a structural skeleton that significantly enhances the physical capabilities of the tile.
The glass fiber mesh is uniformly distributed throughout every corner of the sheet, providing 50% better impact resistance compared to standard plastic roofing. This reinforcement is crucial for 2026 industrial projects that require high-strength solutions to handle snow loads, big wind areas, or accidental impacts during maintenance. This technology allows the sheets to operate reliably in a temperature range from -40°C to 80°C.
Furthermore, this patented reinforcement allows for a 20% longer purlin distance during installation. For a large-scale warehouse, this translates to fewer support beams and reduced steel consumption, leading to significant savings on total project costs. The added tensile strength ensures that the sheets remain stable under weather changes, preventing the warping often seen in lower-quality plastic alternatives.
In 2026, safety compliance and energy efficiency are top priorities for any industrial facility. Our UPVC and resin tiles are designed to exceed these rigorous standards. They are fireproof with a B1 rating, meaning they are hard to burn and self-extinguishing. This fire-protection rating provides essential peace of mind for facilities handling flammable materials or chemicals.
The durability of these sheets extends to extreme weather events. They are effectively waterproof and hail-resistant, protecting the factory interior from damage during severe storms. Because the material does not rust or age rapidly, it maintains its structural integrity against high-impact forces throughout its lifespan. This makes it an ideal choice for acid-picking workshops, smelting plants, and agricultural buildings where the environment is naturally aggressive.
From an energy perspective, the excellent heat insulation of the UPVC layers keeps interiors significantly cooler in the summer. This reduces the reliance on heavy-duty air conditioning systems, leading to lower operational costs. By addressing thermal management at the roof level, we provide a passive cooling solution that lasts for the life of the building.
We believe that providing the right product is only half of the equation; providing the right solution is what builds long-term partnerships. Our technical team is available to help work out project drawings and calculate the exact quantities and lengths required for your specific build. While we do not provide on-site installation guidance, our installation manuals are comprehensive and designed for ease of use by professional Contractors.
To ensure that every batch of roofing meets our high standards, our laboratory conducts a whole set of tests on raw materials, formulas, and finished products. These tests cover aging, tensile strength, impact resistance, and loading capacity. We stand by the quality of our engineering with a 10-year warranty, ensuring that your investment is protected.
