Recently, the Hainan Provincial Department of Housing and Urban-Rural Development officially released the "Hainan Provincial Technical Standard for Metal Roofing" (DBJ 46-075-2025). This standard, tailored to Hainan's unique geographical characteristics of high temperature, high humidity, high salinity, high radiation, heavy rainfall, and frequent typhoons, establishes comprehensive technical specifications covering the entire process from material selection, design and construction, quality acceptance to maintenance and repair. It will officially take effect on April 1, 2026. As a participating unit in the standard's drafting, Canlon was deeply involved in the standard's development, providing crucial support for its practicality and implementation through its core products such as polymer waterproof membranes and metal composite panels, as well as its engineering experience.
Focusing on regional pain points to build a full-chain technology system
Hainan's unique climate places stringent demands on the wind resistance, corrosion resistance, and waterproofing performance of metal roofing. In terms of material selection, the standards are tailored to the highly corrosive coastal environment. Canlon's Fusion® TMP and PMP Integrated Panels, with a surface layer of TPO and PVC waterproof membrane manufactured on a fully imported production line, have passed international certifications such as US FM, EU CE, and UK BBA. Their performance in UV durability testing, salt spray testing, and wind uplift resistance far exceeds standard requirements, providing a reliable solution for roof waterproofing and corrosion protection in coastal environments.

Practice empowers standards integration, photovoltaics becomes an industry benchmark
As a provider of commercial and industrial roofing system solutions, Canlon incorporates its years of engineering experience into standard development. Addressing the wind uplift resistance emphasized in the standards, its systems effectively withstand the strong winds of a category 17 typhoon during dynamic wind uplift testing, ensuring the overall stability of the roofing system. Furthermore, Canlon's dedicated waterproofing solution for photovoltaic roofs perfectly adapts to the technical requirements of integrated roofing photovoltaic development through deep integration of the mounting brackets and photovoltaic system components.
Anchoring green and low-carbon development to lead the industry toward high-quality development
The release of the "Hainan Province Metal Roofing Technical Standard" marks the beginning of a standardized and refined development stage for metal roofing projects in Hainan. Canlon will leverage the implementation of this standard to continue utilizing its technological and practical advantages, providing a more solid guarantee for the safety, durability, and green, low-carbon development of metal roofing in tropical coastal areas, and contributing to the improvement of building engineering quality and the sustainable development of the industry.
