Solar Roof Mounting

The EasyFlex system is built on a highly integrated, standardized, and universally adaptable design philosophy. Its fundamental logic is “standardized rail spine + modular interface attachments.” Regardless of roof type, the upper mounting logic and hardware connections remain consistent. Installers only need to change the lower interface (e.g., non-penetrative clamps, L‑foot kits, or specialized tile hooks) to suit different roof surfaces. In short: one system, multiple roof types.

The system uses ZAM (Zn‑Al‑Mg) coated steel (S350GD), aluminum alloy (AL6005‑T6), and SUS304 stainless steel. The ZAM material offers three key advantages:

1. Superior corrosion resistance – ZM275 coating withstands up to 4,000 hours of neutral salt spray testing, with corrosion resistance 3–10 times that of conventional pure zinc coatings of the same thickness. It also features a unique self‑healing property – when the surface is scratched or cut, magnesium preferentially dissolves and migrates to the damaged area, forming a dense protective film.

2. Excellent mechanical strength – S350GD structural steel has a tensile strength 1.6 times that of traditional aluminum, allowing thinner wall sections (e.g., 1.2 mm) while maintaining higher load capacity.

3. Significant cost savings – Under the same design conditions, the EasyFlex system achieves 20%–30% cost reduction compared to all‑aluminum solutions.

1. Snap‑Fit clips – The innovative mid‑clamps and end‑clamps use a snap‑in mechanism that requires no screws – just push until you hear a “click.” This greatly reduces assembly time and ensures reliable connections.

The material choice provides a strategic advantage:

• Enhanced cost competitiveness – ZAM steel offers substantial raw‑material and processing cost savings compared to anodized aluminum, directly reducing PV project mounting system procurement costs by 20%–30%.

• Performance improvement – While bypassing trade barriers, S350GD structural steel delivers 1.6 times the mechanical strength (tensile and yield) of conventional aluminum – achieving both cost savings and superior performance.

The system weight is carefully optimized:

• Total weight is comparable to aluminum racks 

• This light weight eliminates restrictions on lightweight roof installations, ensuring safe and reliable load‑bearing performance across various roof structures.

• Furthermore, because S350GD steel has 1.6× the strength of aluminum, thinner profiles (e.g., 1.2 mm) can be used to further control weight while meeting load requirements.
