Ducting Information

Tricon Air Systems fabricated accordance with 2005 ‘SMACNA’ standards, ASHRAE standards or as per consultants specifications.

Rectangular duct work has been the main type of duct work in history of HVAC. It is still used today on a greater percentage of commercial projects over any other type. Commercial construction jobs. Every piece we manufacture meets project requirements.

Tricon Air Systems is in fabrication of SPIRAL, OVAL & RECTANGULAR DUCTS & ducts products in galvanized iron steel, aluminum or in stainless steel.

Tricon Air Systems Rectangular duct and fitting are factory fabricated to furnish with a high quality line of products in a board range of standard size. To minimize field-assembly/fabrication cost. Rectangular duct is supplied in length upto 4 feet.

Longitudinal seams are typically made with Pittsburg lock in transverse joint S & C cleat joint, four-bolt connectors are available.

Tricon Air Systems Rectangular duct work can be shipped completely assembled or knock down in ‘L’ shape. Rectangular ducts are standard products are fabricated to meet SMACNA, ASHRAE duct connection/ fabrication standards. We can also custom fabricate rectangular ductwork for commercial and industrial application according to consultant specification.

Tricon Air Systems ducts are available in the following construction:-

Tricon Air Systems steel ducts:-

Tricon Air Systems rectangular ducts are fabricated out of hot dipped galvanised sheets in accordance with 2005 ‘SMACNA’ standards, ASHRAE standards.

 

Stainless steel ducts:-

Tricon Air Systems SS ducts are fabricated out from prime quality SS sheets of 304/316 grades with fully welded longitudinal and transverse joints.

 

Galvanized iron (GI) ducts:-

Tricon Air Systems galvanized iron ducts are fabricated from galvanized sheets (120 GSM) with TDF flange and transverse joints.

 

Aluminium ducts:-

Tricon Air Systems Aluminium ducts are fabricated from aluminium sheets of A-1100/3003/5052/ 6061equal grades sheets with Hemmed ‘S’ & Drive ‘C’ cleats or flanged type transverse joins.

Rectangular Duct

This table gives minimum duct wall thickness (gage) for use of flat type joint systems. Plain S and hemmed as connectors are limited to 2 in. wg maximum. Slips and drives must not be less than two gages lighter than the duct wall nor below 24 gauge. Double $ slips must be 24 gauge for ducts 30 in. (762 mm) wide or less and 22 gauge for greater width.

Types of Ducts:

Rectangular Ducts, Spiral Ducts, Oval Ducts, Plain Round Ducts, Square Ducts, Flat Oval Ducts
