Spiral-wound metal duct Ø200 mm length 3000 mm (galvanized) No name RS200-3M

Spiral-wound metal duct Ø200 mm length 3000 mm (galvanized) is a rigid ventilation pipe designed for transporting air in HVAC, exhaust and industrial ventilation systems. The duct is produced from spiral-wound galvanized sheet, providing consistent inner diameter, mechanical strength and smooth airflow path. With a nominal internal diameter of 200 mm and a length of 3000 mm, the pipe fits standard Ø200 fittings and couplings, enabling straightforward integration into ventilation runs and extraction lines.

Advantages

The galvanized spiral construction delivers corrosion resistance and structural rigidity while keeping the duct lightweight enough for typical installation work. The wound profile ensures concentric geometry and steady airflow with reduced turbulence compared to some flexible alternatives. Standardized diameter and straight 3 m length simplify planning, joining and mounting in series for longer runs, and the metal surface allows for secure fastening and sealing with conventional clamps and sealants.

Suitable for

• HVAC supply and return ductwork in residential, commercial and light industrial buildings
• Workshop extraction and local exhaust ventilation systems
• Connecting inline fans, filters and silencers with Ø200 connections
• Industrial ventilation runs where rigid metal ducts are required

Key specifications

• Internal diameter: 200 mm
• Length: 3000 mm
• Material: galvanized steel (spiral-wound sheet)
• Construction: rigid spiral profile for consistent cross-section
• Surface finish: zinc-coated for corrosion resistance

How to use

Install the spiral-wound duct by aligning its ends with matching Ø200 fittings, couplings or sleeves. Use mechanical clamps, sheet-metal screws or rivets as appropriate to secure joints, and apply duct sealant or tape designed for galvanized steel to ensure airtight connections where required. Support the duct at regular intervals using straps or hangers to prevent sagging and to comply with local installation standards. Where cuts or transitions are needed, use appropriate metalworking tools and deburr edges before joining.

Usage recommendations

For optimal performance, inspect and clean the interior periodically when used for dusty or particle-laden air. Ensure compatibility with connected components such as inline fans and filters rated for Ø200 ducts. When running multiple sections in series, check alignment and seal each joint to minimize pressure loss and leakage.
