U-Shape Aluminum Rail

U-Shaped Rail Solar Bracket – Comprehensive Introduction

The U-Shaped Rail Solar Bracket is a core structural component in metal roof photovoltaic (PV) mounting systems. Engineered for durability, efficiency, and ease of installation, this aluminum rail features a U-profile channel that serves as the mounting base for solar panel clamps and related hardware.

Specifically designed for trapezoidal and corrugated metal roofs, this bracket enables direct roof attachment without the need for long rail systems, reducing overall material usage and labor time. Its compact profile and versatile mounting slots make it ideal for both large-scale solar arrays and small residential projects.

Key Product Characteristics

• Profile: Precision-extruded U-shape with internal grooves to accommodate T-bolts or slide nuts

• Material: AL6005-T5 high-strength aluminum alloy

• Surface Finish: Anodized (10–15μm) for excellent corrosion resistance in extreme outdoor environments

• Length: Customizable (commonly 200mm–400mm for modular use)

  Mounting Hole: Pre-drilled center hole for fixing to metal roof ridges with self-tapping screws

• Optional Accessories: EPDM rubber strip pre-applied on the bottom to enhance waterproofing and vibration isolation

Advantages

Recommended Applications

• Rooftop solar systems on trapezoidal/corrugated sheet metal

• Commercial warehouses, industrial buildings, or barns with metal sheeting

• Residential solar systems with modular bracket requirements

• Ground systems (used with additional structures) where U-rail compactness is an advantage

Installation Notes

1. Align the rail along the ridge of the metal sheet.

2. Fix it using self-tapping screws or rivets through the pre-drilled holes.

3. Attach end- and mid-clamps using T-bolts inserted into the side channels.

4. Ensure the EPDM strip is properly compressed for waterproofing if installed.
