Product details

Rail-free rooftop arrays are now the go-to Components For Solar PV Mounting Structures on space-limited or load-sensitive roofs. By eliminating continuous rails, the system relies on discrete ALUMINUM ALLOY PROFILES clamps that bolt directly to Galvanized Steel Tubes purlins, STEEL PROFILES battens, or hidden brackets, all locked with corrosion-proof STAINLESS PARTS.

Application workflow

1. Metal roofs (standing seam or corrugated)

Pre-assembled clamps—machined from ALUMINUM ALLOY PROFILES and lined with EPDM—snap over the seam and tighten with STAINLESS PARTS set screws, anchoring instantly to Galvanized Steel Tubes ribs beneath. No rail, no penetration.

2. Shingle roofs

Stainless flashing plates slide under the course, then STEEL PROFILES posts rise through the deck. ALUMINUM ALLOY PROFILES clamps grip the panel frame and fasten to the posts using STAINLESS PARTS hardware, distributing uplift loads while keeping weight under 2 kg/m².

3. Tile roofs

Interlocking hooks formed from ALUMINUM ALLOY PROFILES hook onto Galvanized Steel Tubes battens, replacing broken tiles without lifting adjacent rows. STAINLESS PARTS screws secure the module directly, preserving the curved aesthetic.

Field benefits

• Up to 40 % fewer materials versus railed systems, cutting freight costs and rooftop load.

• Faster install—only four STAINLESS PARTS fasteners per module—reduces labor hours and crane time.

• Clean sightlines: panels appear to float above Galvanized Steel Tubes or STEEL PROFILES substructures, meeting strict HOA or heritage guidelines.

For each roof type, experienced installers first verify substrate strength, select matching ALUMINUM ALLOY PROFILES clamps, and specify STAINLESS PARTS torque values, ensuring the rail-less array delivers decades of secure, weather-tight performance.
