Galvanized Steel Ductwork carries supply and exhaust air between ventilation equipment and the spaces it serves. Straight sections, elbows and tees form a connected route around the building structure, reducing improvised joints at changes of direction.
Integral flanges connect neighbouring sections, and the galvanized surface protects the steel against corrosion during normal ventilation service.

MODEL DIFFERENCES
Which configuration fits the task
Screened elbow
The insect-screen version suits an exposed termination where the screen remains accessible for cleaning; it does not replace a particle filter.
DUCTWORK FEATURES
Build the route around the space
Matching runs and fittings
Straight sections, elbows and tees connect the main route, changes of direction and branches in one duct layout.
Flanged connections
Integral flanges provide a defined joint at each duct end for connecting neighbouring sections.
Galvanized metal surfaces
The galvanized finish helps protect the steel against rust during service.
Insect-screen elbow option
A screen at the elbow opening helps restrict insect entry where the duct connects to an exposed opening.
APPLICATION ENVIRONMENTS
Air distribution for buildings and industrial spaces
Hotels and shopping centres
Connect air-conditioning and ventilation equipment to occupied areas through supply and exhaust duct routes.
Factories and warehouses
Route ventilation, exhaust and dust-extraction air between work areas and the associated equipment.
Basements and civil-defence spaces
Provide duct routes for air supply, air exchange and extraction in enclosed underground areas.
Metro facilities and tunnels
Form sections and fittings for the ventilation and smoke-extraction routes specified in the project design.
CUSTOM FABRICATION
Fit the duct to the installation
Opening size and direction
Match the internal opening and elbow angle to the adjoining duct; use tees where the air route branches.
Custom duct sections
Galvanized steel straight runs and fittings can be fabricated to the dimensions required by the installation layout.
