When Typhoon Ragasa recently made landfall along the Guangdong coast, it was declared the strongest typhoon to strike China this year. With winds exceeding the threshold of a super typhoon, the event served as a stark reminder of the challenges faced by buildings in coastal regions. Extreme weather events like Ragasa highlight the urgent need for roofing systems that can ensure long-term protection, structural stability, and safety for property owners.

At WISKIND, we have long recognized this demand, particularly for projects in typhoon-prone regions across Asia, the Pacific, and other coastal areas around the world. To demonstrate the reliability of our products, our team has conducted extensive wind uplift resistance tests under the national standard GB/T 39794.1-2021. The results have proven that our roofing systems go far beyond conventional performance, meeting the toughest requirements for storm resilience.

Rigorous Testing Under Extreme Conditions

One of our most advanced solutions, the SR6 standing seam panel system, was selected for testing. The system incorporates 0.6mm galvanized steel roofing panels combined with a 450° mechanical lock seam technology. This unique design improves joint tightness, significantly reduces risks of panel detachment, and enhances the overall waterproofing and wind resistance of the roof.

The tests simulated multiple levels of typhoon intensity:

12-level typhoon (0.7kPa)

15-level strong typhoon (1.4kPa)

17-level super typhoon (2.1kPa)

Beyond 17-level, extreme super typhoon (2.8kPa)

Beyond 17-level, catastrophic super typhoon (3.5kPa)

Beyond 17-level, maximum test load super typhoon (4.2kPa)

Even under the most extreme pressure level of 4.2kPa, the SR6 roofing system demonstrated remarkable resistance, maintaining both structural integrity and secure panel locking. This performance establishes WISKIND as one of the few manufacturers capable of delivering solutions proven against forces stronger than any recorded natural typhoon.

Quality and Certifications

The outstanding results of these tests are backed by certifications that align with international standards. From system safety to environmental compliance, our roofing products have achieved recognition that reassures clients globally. This combination of laboratory testing and accredited certification means that project owners and contractors can trust our panels for high-stakes applications.

Applications in Coastal and Industrial Projects

Coastal regions in Southeast Asia, the Middle East, and even parts of North America face frequent threats of tropical cyclones or hurricanes. In these regions, building resilience is not optional—it is a necessity. The SR6 system is designed with this in mind. Its standing seam panels provide continuous, weather-tight protection against wind-driven rain and uplift forces, while its strong locking system ensures that the roof remains secure under extreme weather events.

In industrial projects where industrial sheet metal is a fundamental element of design, durability and safety cannot be compromised. Factories, logistics centers, and energy facilities often span large roof areas, making them particularly vulnerable to wind uplift. The use of WISKIND's SR6 system, reinforced with galvanized steel roofing panels, provides a reliable solution that minimizes risk while extending the lifecycle of the building.

Protecting Property and Investments

Every year, typhoons and hurricanes cause billions of dollars in property damage. A significant portion of this loss is directly related to roof failure. Once a roof is compromised, water intrusion and structural damage escalate rapidly, putting people, assets, and entire business operations at risk. By choosing advanced roofing systems tested under the toughest conditions, property owners gain peace of mind knowing their investments are safeguarded.

WISKIND's roofing technology ensures that clients in typhoon-prone countries—from China and the Philippines to Japan and the Caribbean—can count on durable solutions that withstand repeated exposure to extreme winds. The SR6 roofing panel system is not only a practical choice but also an investment in long-term security.

A Future Built on Strength and Trust

With the growing impact of climate change, extreme weather events like Typhoon Ragasa are expected to become more frequent and severe. Construction materials and systems must therefore evolve to meet new levels of resilience. WISKIND remains committed to innovation, ensuring our standing seam panels, galvanized steel roofing panels, and complete structural systems continue to lead the industry in performance and safety.

In conclusion, the proven performance of the SR6 0.6mm roofing panel with 450° lock seam technology under GB/T 39794.1-2021 testing demonstrates the unmatched strength and adaptability of WISKIND roofing solutions. Whether for coastal industrial complexes or large-scale infrastructure projects, our products deliver the security and reliability that customers need to protect their property and people—even in the face of the world's strongest storms.
