Product Advantages

Non-Penetrating Design

Clamps attach only to raised seams, so no drilling is required. This helps preserve roof waterproofing and avoids roof damage.

Wide Roof Compatibility

Suitable for various raised-seam / standing seam metal roof profiles.

Wide Module Compatibility

Compatible with framed and frameless solar modules.

Strong Weather Resistance

Robust design and high-quality materials enable the clamps to withstand wind speeds up to 60 m/s and snow loads up to 1.6 kN/m².

Quick and Easy Installation

Supports single- or double-bolt tightening. Pre-assembly before delivery saves installation time and simplifies on-site construction.

How It Works

The clamps grip the raised seam of the metal roof and provide a stable connection point for solar rails and modules. Because no roof penetration is required, installation avoids unnecessary holes and helps reduce potential leak risks. Pre-assembled components allow fast on-site positioning and tightening.

Roof & Module Compatibility

The clamps are suitable for various metal roof profiles and are compatible with both framed and frameless PV modules. The mounting angle runs parallel to the roof, and modules can be installed in landscape or portrait layout. Customized solutions are available for specific roof profiles and project requirements.

Strength & Durability

Made from AL6005-T5 aluminium and SUS304 stainless steel, the clamps combine light weight with reliable strength. The robust design is engineered to withstand wind speeds up to 60 m/s and snow loads up to 1.6 kN/m². Corrosion-resistant surface treatment supports long-term outdoor performance.
