Ultra-Short Trapezoidal Sheet Metal Rail (180mm) for Metal Roof Solar Mounting
The Ultra-Short Trapezoidal Rail (180mm) is a compact and highly economical solar mounting rail, designed specifically for trapezoidal and corrugated metal roofs. Measuring just 180mm in length, this rail offers maximum material savings while retaining the essential strength and waterproofing features required for secure and durable solar installations. Pre-attached with EPDM sealing, this mini rail simplifies installation and protects against leakage. It’s the perfect solution for budget-driven solar projects that demand performance without excess cost.
At just 180mm, this ultra-short rail uses less aluminum, resulting in lower production, shipping, and storage costs—while still offering reliable module support.
Space-Efficient & Lightweight
Small profile reduces packaging volume and cuts installation time, ideal for projects with high labor costs or tight deadlines.
Built-in EPDM Waterproofing
Like its longer counterpart, this short rail comes with a factory-applied EPDM rubber seal at the base, offering secure, long-term protection from roof leakage.
Simplified Fastening
Compatible with self-drilling screws for direct roof attachment; no complex assembly or bracketing needed.
Universal Compatibility
Fits with all standard mid and end clamps, allowing seamless integration into most solar panel configurations.
Installation Steps
Step1: Layout Planning
Measure module width and mark placement for short rails on the roof ridge points
Step2: Place Rails
Align each 180mm rail over the trapezoidal ridge
Step3: Secure with Screws
Use stainless steel self-drilling screws to fasten the rail through the roof sheet. The EPDM strip automatically seals the drill hole.
Step4: Attach Panels
Use universal solar clamps (mid & end) to secure modules to the short rail
Step5: Grounding and Inspection
Apply grounding accessories as needed. Verify that clamps and rails are tightly secured
Application Scenarios
Small-Scale Residential Roofs
Perfect for budget-sensitive home solar projects
Commercial & Warehouse Metal Roofs
Quick installation across large surfaces
Off-grid & Portable Systems
Ideal for modular or temporary PV structures
Developing Market Deployments
Designed for price-sensitive regions like Southeast Asia, Africa, or Latin America

FAQ
Q1: Is 180mm long enough to securely hold the panel? A: Yes, when paired with proper mid and end clamps and installed at the designated panel contact points, the system provides sufficient support for framed solar panels under standard load conditions.
Q2: Will EPDM alone prevent leakage through the metal roof? A: Yes. The EPDM strip forms a watertight seal when compressed during screw installation, ensuring leak-free performance over the system's lifetime.
Q3: What’s the main difference compared to the 395mm trapezoidal rail? A: The 180mm version is shorter, narrower, and even more cost-effective. It's ideal for high-volume, low-cost projects, whereas the 395mm rail offers a slightly wider footprint for structural redundancy.
Q4: Can I use this rail on standing seam roofs?
A: No. This product is specifically designed for trapezoidal or corrugated sheet metal roofs. For standing seam roofs, we recommend non-penetrating clamp-based solutions.
Q5: Is this rail compatible with all brands of solar modules? A: Yes, it works with any framed panel between 30–50mm thickness, using industry-standard clamps.
