Trapezoidal Sheet Metal Rail for Metal Roof Solar Mounting System

The Trapezoidal Sheet Metal Rail is an economical, lightweight mounting rail specifically designed for metal roofs with trapezoidal or corrugated profiles. Unlike traditional long rails, this short rail system reduces material costs while still offering robust structural support. Pre-fixed with EPDM waterproof gaskets, it ensures excellent sealing and quick installation—making it the ideal choice for cost-conscious and high-efficiency solar installations.

Product Advantages



Material & Cost Efficiency

Short rails reduce aluminum usage, saving up to 30% on materials compared to full-length rail systems.

Fast and Easy Installation

Directly mounted onto metal roof ridges using self-tapping screws—no need for long spans or multiple connectors.

Built-in Waterproofing

Each rail is pre-attached with EPDM rubber strip, ensuring tight sealing and leak protection around screw points.

Low Profile Aesthetics

Sleek design minimizes wind resistance and offers a clean, non-intrusive look on rooftops.

Universal Fit

Compatible with all major brands of framed solar panels and various metal roof shapes.

Installation Steps

116

Step1: Plan Layout

Based on module size and roof design, mark where short rails will be fixed

Step2: Position the Rails

Align the trapezoidal rails with the ridges of the roof panels

Step3: Drill and Fix

Use self-tapping screws to fix the rail to the metal sheet. The EPDM gasket compresses to seal the holes completely


Step4: Install Clamps

Use mid and end clamps to mount the solar panels onto the short rail

Step5: Grounding

Apply grounding lugs and bonding jumpers as needed

Step6: Final Check

Ensure rails and panels are aligned and securely fixed

FAQ

Q: What is the difference between short rail and traditional rail systems?

A: Short rails (mini rails) require less material and are mounted directly under the panel at connection points, while traditional rails span the entire module length. Short rails are faster and cheaper but slightly less flexible in complex layouts.

Q: Does the EPDM really prevent leakage?

A: Yes, the industrial-grade EPDM strip forms a tight waterproof seal when compressed under screw pressure, preventing any water ingress through the roof.


Q: Can I use this rail with any solar panel brand?

A: Yes, as long as your panel has a standard aluminum frame (30–50mm), this rail works with all mainstream clamps and modules.


Q: Is it strong enough for snow-heavy areas?


A: When correctly spaced and installed, the system can withstand up to 1.4 KN/m² snow loads and 60 m/s wind loads.


Q: Can I install this system myself?

A: While possible for DIY users with basic tools, we recommend installation by trained professionals to ensure safety and compliance with local codes.
