🔑 Features 

• Cost-effective: Less material than full rails.Ideal for cost-sensitive projects with metal roofs.

• Quick installation: Fewer components and faster assembly. 

• Lightweight: Reduces structural load on the roof. Versatile for different PV module types.

🛠️ Installation Guide: Solar Aluminum U Shape Mini Rail Structure

🔧 Tools You May Need:

• Cordless drill

• Tape measure

• Self-tapping screws

• Torque wrench

• EPDM sealing pad (if not pre-attached)

✅ الخطوة 1: Mark the Panel Layout

• Measure and mark the positions where each solar panel will be installed.

• Align these positions with the ribs of the metal roof to ensure secure attachment points.

✅ Step 2: Position the U Shape Mini Rails

• Place the U-shaped mini rail across the roof ribs according to your module size and mounting layout.

• Ensure the rail is aligned parallel and level to maintain the correct tilt and spacing.

✅ Step 3: Fix the Rail Using Screws

• Use براغي ذاتية التثبيت (with EPDM sealing washers) to fasten the mini rail directly onto the roof sheet rib.

• Tighten using a torque wrench, but do not overtighten to avoid deforming the roof panel or striping the screw thread.

✅ Step 4: Attach the UI-SS04 Hook Clamp

• Slide the mid/end clamp into the U-groove of the rail.

• Align with the panel’s mounting holes or frame edge.

✅ Step 5: Mount the Solar Panels

• Lift and position the solar panel onto the mounted U rails.

• Secure using mid clamps between panels and end clamps at both ends.

• Tighten all clamps to the recommended torque setting.

✅ Step 6: Final Inspection

• Double-check all clamps and screws for tightness.

• Ensure the panels are straight, evenly spaced, and firmly secured.

• Clean any debris or metal shavings from the roof area.

🔄 Repeat as Needed

• Repeat the above steps across your roof, adjusting for rib spacing (e.g., 2 / 4 / 5 / 8 ribs).

• Modular and flexible for fast deployment in large-scale B2B or residential projects.

📝 Pro Tips:

• Pre-drill holes if working on thicker roof sheets.

• Use anti-corrosion paste for fasteners in highly humid or coastal areas.

• Always follow local building codes and solar PV mounting standards.
