Custom HVAC Duct Fabrication
Precision-fabricated custom HVAC ductwork for commercial and residential projects across New York City. From rectangular fittings to complex transitions, we build it all in our Brooklyn sheet metal shop.
Precision Duct Fabrication for NYC Contractors
At Metal Men Mechanical, custom HVAC duct fabrication is what we do best. Operating out of our fully equipped Brooklyn sheet metal shop, we produce rectangular, round, and oval ductwork engineered to meet the demanding specifications of New York City's commercial and residential HVAC systems.
Every piece of ductwork that leaves our shop is fabricated to your exact measurements. We work directly from your PDF drawings, DWG files, and duct schedules to ensure precise fits that save time on the job site. No rework, no delays — just ductwork that goes in right the first time.
Full-Service Custom Duct Fabrication
Our custom duct fabrication capabilities cover the full range of HVAC ductwork needs. We fabricate rectangular duct in gauges from 26 to 16, including all standard fittings — elbows, tees, wyes, reducers, offsets, and transitions. Our TDC (transverse duct connection) and S-drive connections meet SMACNA standards for both low and medium-pressure applications.
For round duct requirements, we produce both straight sections and fittings in standard and custom diameters. Oval ductwork is available for tight plenum spaces where height restrictions prevent the use of standard rectangular or round profiles. Whatever the application calls for, we can build it.
Why NYC Contractors Choose Our Custom Duct Fabrication
Speed and accuracy define our custom fabrication process. Most standard orders ship within 3–5 business days, with rush orders available for urgent timelines. Our team of experienced sheet metal fabricators averages over 15 years in the trade, bringing deep knowledge of NYC building codes, mechanical specifications, and field installation requirements.
We understand that contractors need ductwork that fits the first time. Misfabricated duct means wasted labor hours, project delays, and cost overruns. That is why we invest in precision equipment including CNC plasma cutters, coil lines, and automated duct formers that produce consistently accurate results.
Serving Every Borough from Brooklyn
Our Brooklyn shop at 993 Grand St is centrally located to serve contractors across all five boroughs. Whether you are working on a high-rise in Manhattan, a commercial buildout in Queens, or a residential retrofit in the Bronx, we deliver custom ductwork on your schedule.
We maintain a fleet of delivery vehicles and coordinate with contractors on staging and delivery timing. For large commercial projects, we can phase fabrication and delivery to match your installation schedule, keeping your job site organized and your crews productive.
