Fire Shutter Construction
Fire shutters consist of slats, barrel, guide rails, and electric drive. The slats are cold-rolled steel strip, 1.5mm thick, formed into interlocking C-shaped panels — good rigidity, good sealing. Optional smoke, heat, and flame detection alarm systems plus water curtain sprinklers are available.
Key Features
- Fire resistance: High ignition point material that doesn't catch fire easily.
- Thermal insulation: The thick material helps with temperature control on the non-fire side.
- UV protection: In summer, these products block ultraviolet radiation effectively.
