How "Durable" And "Safe" Is This Product Exactly?

When choosing a photovoltaic support system, the two questions that people are most concerned about are always: How durable is it? And how safe is it? Today, we won't talk nonsense. Instead, we will use data and facts to dissect a support system that can truly withstand extreme environments and accompany you for over thirty years. 

I. Withstanding Extreme Weather

Wind Resistance：

This system generally boasts a maximum wind resistance of 60 m/s, with some high-performance models reaching 70 m/s. What does that mean? It's equivalent to the center wind speed of a Category 17 super typhoon.

Snow Resistance:

The system can generally withstand a snow load of 1.4 kN/m², with some models even capable of withstanding 1.6 kN/m² or adapting to snow depths of 2500 mm. This means that even in areas where heavy snow closes off the mountains, you don't have to worry about the support structure collapsing under the weight of the snow.

II. Corrosion Resistance and Lifespan 

Materials and Craftsmanship

The main body of the support frame is made of high-strength AL6005-T5 aluminum alloy, and undergoes anodizing surface treatment to form a dense protective film. All exposed fasteners are made of SUS304 stainless steel—leaving no screw untouched, completely eliminating the risk of rust.

Data Speaks for Itself

The authoritative salt spray test results show that no corrosion occurred after 72 hours of the CASS test, which is equivalent to being resistant to the elements for 30 years in a real outdoor environment.

Overall Expectations: The main structure of the system has a corrosion-resistant lifespan of over 30 years, and the overall design lifespan of the support system is generally over 25 years.

III. Foundation Stability

Working Principle: Locking the Earth Like a Screw

The helical pile, with its unique helical blades, tightly engages with the surrounding soil, effectively resisting uplift forces during strong winds. Tests show its pull-out resistance can exceed 3 tons—equivalent to lifting a small SUV.

Intelligent Response to Different Geological Conditions

• Loose/Soft Soil: Bearing capacity can be ensured by increasing pile length, using thicker helical piles, or increasing the diameter of the helical blades. Manufacturers offer various size configurations.

• Frozen Soil Areas: The frost pull-out resistance of helical piles is far superior to traditional smooth piles. During construction, ensure the pile tip penetrates below the frost line. In some extreme areas, vibration-assisted or heating components can be used to enhance stability.

• Construction Control: The pile reaches its design bearing capacity by controlling the screwing torque (typically between 2000-5000 N·m). Each pile has a "torque record."

IV. Professional Certifications 

Authoritative Certifications

Mainstream aluminum alloy bracket systems typically pass the following certifications:

• CE (EU Safety Certification)

• TÜV (German Inspection Association)

• ISO 9001 (Quality Management System)

These certifications ensure that their design, manufacturing, and quality control meet the highest international standards.

Strictly Adhering to International Standards

System designs simultaneously meet the requirements of multiple countries and regions:

• AS/NZS 1170 (Australia/New Zealand)

• JIS C 8955 (Japan)

• GB50009 (China)

• Eurocode (Europe)

Summary: A "Long-Term" Product to Accompany You Through Life Cycles

AL6005-T5 aluminum alloy + anodized finish + SUS304 stainless steel fasteners—these three elements combine to create over 30 years of exceptional corrosion resistance, the core guarantee of the support system's long lifespan. The helical pile foundation, through its ingenious structural design, ensures long-term stable support in various harsh environments, from coastal to inland areas, from soft soil to permafrost.

More importantly, this isn't just theoretical—countless successful projects, from Lingao in Hainan to Kumamoto in Japan, have validated its reliability. Coupled with certifications from international authoritative organizations such as CE and TÜV, you can confidently say:

"This product is not only durable, but also truly safe."
