Choose from multiple fittings for your application
We fabricate a full range of commercial HVAC duct systems and components, built to your specifications and project requirements. Choose connection types, metal gauge thicknesses and longitudinal seam types. Every project is built based on your plans, specs, and field requirements so there's no guesswork!
Straight Duct
Straight duct sections form the primary runs of a commercial HVAC system, carrying air between equipment, branches, and terminal points.
We fabricate rectangular straight ductwork in standard and custom lengths, ensuring consistent fit, structural integrity, and alignment in the field.
90° Elbow (Square Elbow)
90-degree elbows are used to create sharp directional changes in duct systems where space constraints require tighter turns.
Our square elbows are fabricated for durability and proper airflow control, making them a reliable solution for compact duct layouts.
45° Elbow
45-degree elbows provide a more gradual directional change, helping reduce turbulence and improve airflow efficiency.
We fabricate 45° duct elbows for commercial HVAC systems where smoother transitions are preferred for performance and system balance.
Radius Elbow
Radius elbows are designed with a curved profile to improve airflow and reduce resistance compared to square elbows.
Our radius elbows are commonly specified in commercial projects where airflow efficiency and system performance are critical.
Transition
Transitions are used to connect duct sections of different sizes or shapes, such as rectangular-to-round or changes in duct dimensions.
We fabricate custom duct transitions to ensure a proper fit and maintain consistent airflow throughout the system.
Radius Transition
Radius transitions combine a size change with a curved airflow path, helping reduce turbulence and improve system efficiency.
These fittings are ideal for systems where both dimension changes and airflow performance must be optimized.
End Cap
End caps are used to terminate duct runs and seal system endpoints.
We fabricate duct end caps that ensure proper system closure, pressure control, and a clean finished installation.
Rectangular Tap
Rectangular taps create branch connections from main duct lines, allowing air distribution to multiple zones.
Our rectangular duct taps are fabricated for secure connections and efficient airflow distribution in commercial HVAC systems.
Shoe Tap
Shoe taps are specialized fittings designed to improve airflow as air enters a branch duct from the main trunk.
We fabricate shoe taps for duct systems that help reduce turbulence and improve overall system performance.
