Ultra-Short Trapezoidal Sheet Metal Rail (180mm) for Metal Roof Solar Mounting
Product Description
| Most Cost-Effective Rail on the Market | |
| 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. |
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

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.
