How can metal roofing systems calmly cope with the climate challenges of "ice and fire"?
This summer, persistent high temperatures scorched many regions, with surface temperatures in some cities exceeding all-time highs. Simultaneously, historic heavy rainfall in the Beijing-Tianjin-Hebei region and the torrential downpours brought by Typhoon "Hypokalpa" to coastal areas followed closely behind, creating alternating periods of scorching sun and torrential rain.
In extreme rainstorms, the instantaneous excessive rainfall often exceeds the drainage capacity of the roof panels, causing concentrated leakage and dripping problems; the threat of wind damage is significant, and factories with insufficient wind-uplift resistance are forced to stop production because their roofs are overturned by strong winds; traditional roof systems cannot release stress due to the thermal expansion coefficient of the panels, design defects, etc., which leads to frequent structural damage and other problems.
Locklingding® Metal Roofing System
Deeply engaged in the metal enclosure industry, Hongxinyuan has introduced cutting-edge Japanese metal roofing technology based on the experience of over one million square meters of roofing projects and developed the Suolingding® metal roofing system, which has made further innovations and improvements in drainage capacity, wind resistance, strength and safety, and climate adaptability.
1.Excellent waterproof and drainage capabilities
The unique ribbed structure, combined with a reliable locking edge anti-seepage design, effectively blocks capillary water seepage. The 92mm deep rib cross-section achieves a safe water diversion depth of 34mm, significantly exceeding the drainage threshold of conventional roof systems. This design ensures rapid drainage of water in transient rainstorm conditions. Water spray tests have verified that the locking edge joint maintains zero seepage at extreme water depths, completely resolving the problem of water backflow on low-slope roofs.
2.Super strong wind resistance
The scientific panel design provides excellent mechanical stability, and the reliable locking method between the panel ribs and the brackets resists wind-uplift caused by deformation of the roof panel under strong winds. The system has passed the GB50205-2020 wind-uplift test. Compared with conventional metal roofs, the Hongxinyuan Suolingding roof system has superior wind resistance.
3.Applicable to various scenarios
The system is highly adaptable to structural deformation caused by temperature fluctuations and can accommodate complex roof structures such as large spans, arches, low slopes, and extra-long roof panels. It maintains long-term performance in extreme environments such as coastal high salt spray, industrial corrosion zones, and severe freeze-thaw conditions. The system can customize the optimal roof solution based on the project, helping architects realize their creative ideas.
4.Convenient installation and maintenance
Prefabricated construction and simple working procedures. If the roof panel is damaged, the round buckle head makes it easy to replace and restore the roof panel.
5.Excellent corrosion resistance
The steel plate's surface is treated with high-quality, high-aluminum galvalume or galvalume-magnesium coatings. These coatings, composed of aluminum, zinc, and silicon, are cured at high temperatures to form a dense, quaternary crystal barrier on the steel plate's surface. This effectively blocks the penetration of corrosive agents and resists the combined effects of high temperatures and freeze-thaw cycles. A smooth, locked-edge process ensures zero damage to the coating during application, providing an exceptionally long 30-year corrosion protection cycle.
6.Complete accessories system
Complete accessories are the key support to ensure that the roof system is waterproof and leak-proof, overall stable and durable under extreme conditions such as heavy rain, strong wind tearing, freeze-thaw cycles, etc.
7.Additional layers and auxiliary systems
Photovoltaic panels, decorative aluminum panels, snow guards, inspection trails and other systems can all be rooted in the roof without perforations, completely eliminating potential leakage risks caused by punching holes during temperature difference deformation and freezing and thawing.
