Import Flexible Duct — Buy in Bulk from Supplier in Sri Lanka

The flexible duct from Spk Flex Corp., (private) Ltd. is constructed with a spring steel wire framework with a wall thickness of 0.019mm, coated in galvanized material to resist corrosion. The outer layer is made from inflammable polyester fabric cloth, compliant with standard fire safety requirements for HVAC applications. This design allows the duct to maintain shape under pressure while remaining pliable for routing through confined spaces in residential and commercial buildings.

The product is available in standard diameters ranging from 75mm to 300mm, matching common HVAC outlet sizes. The galvanized coating provides moderate protection against moisture, making it suitable for use in humid environments. The polyester fabric is treated to resist UV degradation and microbial growth, which aligns with typical industry expectations for non-metallic ventilation ducts used in air handling systems. It does not include internal insulation or thermal lining.

This duct is commonly used in HVAC exhaust systems, bathroom ventilation, and kitchen range hood installations. Buyers include mechanical contractors, building refurbishment firms, and small-scale HVAC distributors in South Asia and the Middle East. Packaging is in bulk rolls or individual lengths, sealed in polyethylene. Minimum order quantities are not stated; buyers must confirm packaging options and lead times directly with the supplier. Shipping terms are typically FOB Colombo.
