T-slot aluminium rail for portrait-orientation panels on trapezoidal metal roofs. Four variants — 100 mm, 70 mm, 65 mm and 100 mm Pro — to match any project clearance or wind-load requirement.

## MonoRail 100mm

*100 mm Roof Clearance*

**Standard 100 mm clearance — maximum ventilation, the most popular choice for commercial projects.**

The MonoRail 100mm provides 100 mm of clearance between the panel underside and the roof surface, ensuring excellent natural ventilation and module cooling. The precision T-slot extrusion accepts U-clamps and mid-clamps for all standard panel thicknesses. Rivet-and-EPDM tape attachment to the roof crest is the standard fixing method; a structural-adhesive option is available for non-penetrative installation.

### Highlights

- 100 mm clearance for maximum ventilation & cooling
- Lightweight single-rail design
- Optimised for any trapezoidal crest width
- Portrait orientation — high module capacity
- U-clamp & mid-clamp panel attachment
- Compatible with all PV module brands

**Applications:** Commercial rooftop, Industrial shed, Large residential, Warehouse

### Specifications

| Specification | Value |
| --- | --- |
| Profile Height | 70 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 | Portrait |
| Attachment | Rivet + EPDM tape / Structural adhesive |
| Finish | Anodized / Non-anodized |

## MonoRail 70mm

*70 mm Roof Clearance*

**Low-profile 70 mm variant — reduced wind moment, ideal for high wind-load zones.**

The MonoRail 70mm uses the same T-slot profile but reduces mounting height to 70 mm above the roof crest. The lower centre of gravity reduces the wind-induced bending moment at the base fixing, making it the preferred choice for coastal or high wind-load sites. Panel attachment and material specifications are identical to the 100 mm variant.

### Highlights

- 70 mm clearance — reduced wind moment vs 100 mm
- Lower visual profile on roof
- Preferred for coastal & high wind-load zones
- Portrait orientation — high module capacity
- U-clamp & mid-clamp panel attachment
- Compatible with all PV module brands

**Applications:** Coastal installation, High wind zone, Commercial rooftop, Industrial shed

### Specifications

| Specification | Value |

| Profile Height | 70 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 | Portrait |
| Attachment | Rivet + EPDM tape / Structural adhesive |
| Finish | Anodized / Non-anodized |

## MonoRail 65mm

*65 mm Roof Clearance*

**Ultra-low 65 mm clearance — minimum profile for sites with the strictest height or wind constraints.**

The MonoRail 65mm is the lowest-clearance variant in the Mono Rail range, bringing panels within 65 mm of the roof surface. This ultra-low profile delivers the smallest wind-exposed area of any mono-rail configuration, minimising uplift forces in severe wind environments. Ideal for coastal industrial rooftops and any site where height restrictions apply.

### Highlights

- 65 mm clearance — minimum wind-exposed profile
- Lowest uplift force in the Mono Rail range
- Portrait orientation — high module capacity
- Ideal for height-restricted & coastal sites
- U-clamp & mid-clamp panel attachment
- Compatible with all PV module brands

**Applications:** Coastal installation, High wind zone, Height-restricted site, Industrial shed

### Specifications

| Specification | Value |
| --- | --- |
| Profile Height | 70 mm |
| Roof Clearance | 65 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 / Structural adhesive |
| Finish | Anodized / Non-anodized |

## MonoRail 100mm Pro

*100 mm Clearance · Heavy Duty*

**Heavy-duty 100 mm Pro — reinforced profile for large-span purlins and premium commercial projects.**

The MonoRail 100mm Pro shares the 100 mm clearance of the standard variant but uses a heavier-gauge aluminium extrusion with greater wall thickness for improved bending stiffness. This allows wider fixing spacings along the roof purlin, reducing the number of penetrations on large commercial or industrial rooftops. The Pro grade also supports heavier bifacial panel modules.

### Highlights

- Heavy-gauge extrusion — wider purlin spacing
- 100 mm clearance for maximum ventilation
- Supports heavier bifacial panel modules
- Fewer roof penetrations on large-span roofs
- Portrait orientation — high module capacity
- Compatible with all PV module brands

**Applications:** Large commercial rooftop, Premium project, Bifacial module installation, Industrial shed

### Specifications

| Specification | Value |
| --- | --- |
| Profile Height | 70 mm (heavy-gauge wall) |
| Roof Clearance | 100 mm |
| Panel Thickness | 30 mm · 35 mm · 40 mm |
