# Mini Rail Solar Mounting Structure > Mini Rail low-profile aluminium solar mounting for trapezoidal roofs. Landscape panels, 70 mm & 100 mm clearance or Short Rail, rated to 200 km/h. Source: https://www.sunmount.in/products/mini-rail Manufacturer: Sunmount Solutions Private Limited, Surya Koti, Bajekan-Sirsa Main Road, Sirsa, Haryana 125055, India Quote: https://www.sunmount.in/contact · sales@sunmount.in · +91 78379 99222 Catalogue (PDF): https://www.sunmount.in/catalogue.pdf Low-profile compact extrusion for landscape-orientation panels on trapezoidal roofs. Three variants — 100 mm, 70 mm and Short Rail — covering all clearance needs from standard to compact-bay installations. ## MiniRail 100mm *100 mm Roof Clearance* **Standard 100 mm clearance — optimal ventilation for residential & light commercial projects.** The MiniRail 100mm delivers 100 mm of roof clearance in a compact 68 mm profile height. Landscape panel orientation maximises row width on narrower roofs. Z-clamp and end-clamp attachment accommodates all standard panel frame thicknesses without additional tooling. Rivet-and-EPDM tape base fixing preserves the roof membrane. ### Highlights - 100 mm clearance — excellent ventilation - Compact 68 mm profile — minimal visual impact - Landscape orientation for wider rows - Z-clamp & end-clamp panel attachment - Minimal raw material usage — cost-effective - Compatible with all PV module brands **Applications:** Residential rooftop, Light commercial, Warehouse, Industrial shed ### Specifications | Specification | Value | | --- | --- | | Profile Height | 68 mm | | Roof Clearance | 100 mm | | Panel Thickness | 30 mm · 35 mm · 40 mm | | Material | Aluminium 6063 T6 · SS 304 · EPDM | | Design Wind Speed | Up to 200 km/h | | Orientation | Landscape | | Attachment | Rivet + EPDM tape | | Finish | Anodized / Non-anodized | ## MiniRail 70mm *70 mm Roof Clearance* **Compact 70 mm clearance — lower profile for wind-sensitive or aesthetically driven projects.** The MiniRail 70mm reduces the mounting height to 70 mm, creating an even lower profile that blends with the roof line. Ideal for sites with strict visual guidelines or higher wind-load requirements. Panel attachment and material specifications are identical to the 100 mm variant. Its cost-efficiency makes it a frequent choice for residential developments. ### Highlights - 70 mm clearance — near-flush roof profile - Low visual impact — aesthetics-driven projects - Reduced wind moment vs 100 mm variant - Landscape orientation — wider row coverage - Most cost-effective in the Mini Rail range - Compatible with all PV module brands **Applications:** Residential rooftop, Aesthetics-sensitive site, High wind zone, Light commercial ### Specifications | Specification | Value | | --- | --- | | Profile Height | 68 mm | | Roof Clearance | 70 mm | | Panel Thickness | 30 mm · 35 mm · 40 mm | | Material | Aluminium 6063 T6 · SS 304 · EPDM | | Design Wind Speed | Up to 200 km/h | | Orientation | Landscape | | Attachment | Rivet + EPDM tape | | Finish | Anodized / Non-anodized | ## Short Rail *Compact Span · Portrait* **Compact short-span rail for narrow bays, canopies and retrofits — same T-slot, all SunMount clamps compatible.** The Short Rail is a compact aluminium extrusion for rooftops where a full-length rail is impractical due to narrow bay widths, limited purlin spans or modular roof layouts. Its reduced length minimises material usage and simplifies logistics while keeping the same T-slot profile that accepts every SunMount U-clamp, Z-clamp and mid-clamp. Ideal for canopies, carports and residential retrofits. ### Highlights - Short span — designed for narrow-bay rooftops - Reduced material & logistics cost - Same T-slot — all SunMount clamps compatible - Modular — cut to exact bay width on site - Fast installation on compact or retrofit projects - Compatible with all PV module brands **Applications:** Compact residential, Canopy / carport, Narrow-bay industrial, Retrofit installation ### Specifications | Specification | Value | | --- | --- | | Profile Length | Short-span (custom cut) | | Profile Height | 68 mm | | Panel Thickness | 30 mm · 35 mm · 40 mm | | Material | Aluminium 6063 T6 · SS 304 · EPDM | | Design Wind Speed | Up to 200 km/h | | Orientation | Portrait | | Attachment | Rivet + EPDM tape | | Finish | Anodized / Non-anodized | ## Compare Mini Rail System variants | Specification | MiniRail 100mm | MiniRail 70mm | Short Rail | | --- | --- | --- | --- | | Profile Height | 68 mm | 68 mm | 68 mm | | Roof Clearance | 100 mm | 70 mm | — | | Panel Thickness | 30 mm · 35 mm · 40 mm | 30 mm · 35 mm · 40 mm | 30 mm · 35 mm · 40 mm | | Material | Aluminium 6063 T6 · SS 304 · EPDM | Aluminium 6063 T6 · SS 304 · EPDM | Aluminium 6063 T6 · SS 304 · EPDM | | Design Wind Speed | Up to 200 km/h | Up to 200 km/h | Up to 200 km/h | | Orientation | Landscape | Landscape | Portrait | | Attachment | Rivet + EPDM tape | Rivet + EPDM tape | Rivet + EPDM tape | | Finish | Anodized / Non-anodized | Anodized / Non-anodized | Anodized / Non-anodized | | Profile Length | — | — | Short-span (custom cut) | ## Mini Rail System FAQ ### Where is the Mini Rail System used?
