Custom configuration based on opening dimensions, drawings, performance requirements and destination market.
Roller shutter doors coil the curtain into a barrel above the opening, so they need very little headroom and no side tracks. This suits shopfronts, warehouses, workshops and parking entrances where space around the opening is tight. Slat profile, material and drive are selected per project rather than from a fixed model range.
Images shown demonstrate Senhai's manufacturing, panel and finishing capabilities. Product-specific drawings and relevant references are available during quotation.
