STJH-GALVANIZED-STEEL-RECTANGULAR-AIR-DUCT-1000X500

Galvanized Steel Rectangular Air Duct 1000 x 500 mm Reinforced

Reinforced trunk duct with a 1000 x 500 mm airway for large supply and return routes.

Large opening carries trunk airflow at lower velocity than a smaller section at equal volume.
Hat-shaped stiffeners support broad sheet-metal panels.
Perimeter joints allow modular replacement of straight lengths.

Product Introduction

A half-square-metre internal section suits principal air-distribution runs. The longer panel spans use visible stiffening members, while the galvanized shell and end frames form a robust rectangular assembly for connection to large fittings.

Solutions for Your Application

Broad panels can flex under fan pressure.

Dedicated stiffening members reduce unsupported spans.

A trunk must connect to several smaller runs.

Matching transitions and take-off fittings divide the main airway into downstream branches.

Available Options

Insulated double-skin configuration
Custom branch transition fittings
