When buying an aluminum alloy roller shutter you may not know the profiles or the installation, so RHidoor covers the basics. Against ordinary shutters, aluminum wins on looks, eco-friendliness, and safety. You can spray any color or pattern on the surface, or apply a film with embossed wood or sand texture, which lifts the grade of your shop and helps it stand out.
The curtain’s material and structure block strong light and UV, ending the greenhouse effect from sunlight indoors. It suits any climate, protects the indoor space long term, and testing shows 100% sun block and over 95% temperature block.
Aluminum shutter profiles and models:
77#, 65#, 55#, 50#, plus perforated 77# and 50#.
Two common profiles:
1. Double-layer aluminum slat, effective width 77 mm, with a noise-damping strip between slats for truly silent operation. A thickened, widened aluminum guide gives wind resistance for large spans. Used in villa garages, shops, and large factories or warehouses; max span 8.5 m.
2. Double-layer non-perforated aluminum slat, effective width 55 mm, with a 20×2.3 mm vent hole at the hook for light and air. The noise-damping strip keeps it silent. Use width ≤4000 mm.
Installation:
1. Check the manual chain hangs down, fix the motor to the board, link the chain to the wheel and motor base gear (tighten well), connect the remote box to the motor, and test the handle direction. If reversed, the remote receiver has a black button on the side; flip it to the other side.
2. Measure the main and sub boards to confirm size, then set the shaft on the side plates. First mark a level line on the shaft, drill with a 10 mm bit every 50 cm (keep them straight), weld a 14 mm nut to the shaft perpendicular to its hole and weld it firm. Align the first slat center with the shaft hole and drill vertically with a 10 mm bit. (You can also use self-tappers; thread the aluminum slats and cap both ends, riveting each as you go.) After capping, loop a rope over the shaft and drill a hole in the curtain, tie one end, have someone hold the other, press the up button to run the shaft and pull the curtain up, and bolt the curtain to the shaft (level, tightened with washers). Raise it firmly.
3. Cut one rail end into a V, level the curtain, set the upper and lower limits: left pulley is the upper limit, right is the lower.
