Automatic Shutter Brushed Insertion Strip
Geometric Design and Cross-Section Analysis:Base Width: 11 mm (Provides stabilization by fitting flush into the vertical profile channel).Total Height: 22 mm (Its deep structure tolerates pallet deflection).Functional Structure: The product features a combined design incorporating a flexible sealing lip (fin) that applies pressure to the shutter pallet on the rear surface, and a triple brush bed (indicated by red lines) on the side that allows for hair/brush integration.Functional Role in the System:Friction and Wear Prevention: Prevents metal-to-metal contact as shutter pallets move up and down within the vertical guide (rail) profile.Sound and Whistle Barrier: Prevents shutter pallets from rattling and making noise as they sway within the rail in strong winds. Eliminates wind whistling sound.Dual-Layer Insulation: Both the plastic sealing lip and integrated brush structure work together to prevent dust, leaves, wind, and rainwater from seeping in through two stages.Target Sector and Application Area:Automatic coil shutter manufacturers, sectional door producers, industrial warehouse door installers, and factories producing aluminum/steel shutter systems.Raw Material and Tolerance Identity:PVC and TPE Extrusion: The base and body section passing through the vertical channel is optimized for easy installation; the upper lip section contacting the pallet features flexibility to prevent scratching (Co-ex production technology).Precise mold tolerances allow smooth sliding into aluminum guide rails without jamming.Climatic and Thermal Stability:PVC Alternative: Operates between -20°C and +60°C. Offers highly economical insulation for standard store and shop shutters.TPE Alternative: Between -40°C and +80°C, provides complete resistance to harsh exterior façade conditions and sun-heated metal profiles. Does not harden or crack during freezing; does not sag in summer heat.Packaging and Production Footage:Standard Spool: The standard packaging/spooling quantity established by our factory for this model is 200 meters.Flexible Solution: To minimize scrap rates on automatic shutter manufacturers' and large projects' assembly lines, custom metrages (sizes) on spools or reels are provided according to customer request and order quantity.Custom (Custom Order) Flexibilities:Color options in Anthracite Grey, Black, White, or Grey according to shutter profile color.Custom size cutting advantage according to the customer's vertical shutter heights to eliminate manufacturing scrap.
