A large number of early‑built industrial factories have entered the renovation cycle for roof refurbishment and enclosure upgrading. Practical problems, including aging daylighting components, roof leakage, insufficient daylighting effect and excessive energy consumption, push enterprises to carry out systematic roof reconstruction. Unlike new construction, renovation projects require full compatibility with existing steel structures and metal roof profiles, and need to solve challenges such as old‑new structure connection, joint waterproofing, and load matching.
Market demands have changed accordingly. Buyers are no longer satisfied with the simple supply of standard sheets. They attach great importance to full‑range implementation capacity, covering condition assessment, product selection, profile matching, waterproof joint treatment, installation guidance, and maintenance suggestions. Simple product supply can hardly handle complex renovation conditions. Complete daylighting solutions with balanced structural compatibility, waterproof reliability, and long‑term weather resistance are gaining popularity among project owners. Meanwhile, the industry is promoting coupled research between material R&D and building structures to improve product adaptability for diversified renovation scenarios.
