Aluminum roller shutters are a modern building envelope solution that combines security, sun shading, heat insulation, sound insulation, and low maintenance, widely used in residential, commercial, and industrial settings. Background and Functional Positioning: The core value of aluminum alloy roller shutters lies in their multi-functional integration: Security and protection (e.g., anti-pry structure, motor locking) Excellent physical properties: rainproof (stepped slat design to divert rainwater), sunproof, heat insulation, and sound insulation; Compatible with intelligent systems: supports motor drive, remote control, and integration with building automation systems; Aluminum alloy roller shutters have transcended traditional sun shading accessories, evolving into a building system component that integrates safety, energy saving, intelligence, and customization. Three key elements for accurate measurement: Outer frame width: Measure the widest value at the top, middle, and bottom of the window opening. Outer frame height: Measure the highest value at the left, middle, and right of the window opening. Window depth:Fixed/casement window ≥ 8 cm; single sliding window ≥ 10 cm; double sliding window ≥ 15 cm; folding window ≥ 10 cm. Layout and positioning:Determine the bottom edge elevation of the window using the floor level + 1250px horizontal line as a reference; use a plumb line to draw the window edge line, and chisel and trim any deviations.
