You Want Our Welding. Our welding shop produces the best welded ductwork and accessories in the industry. More than a catchy slogan, you will love our prices, our turnaround, and most importantly our AWS Certified Welding. To meet our shop and quality standards we only use 14-gauge black iron, 16-gauge stainless steel, and 16-gauge galvanized steel for our welded items. These heavier gauge standards allow us to fabricate products that are easier to weld and install in the field.
This allows our customers to save time on the job, install a great-looking product, and make money. We also offer welded assemblies. By welding fittings together in the shop we can eliminate welds in the field, which also saves time and money. Each assembly is smoke tested before it leaves our doors to ensure you are getting a leak-free, AWS-certified, Union Made: Madon Sheet Metal Product. Call Today and see how we continue to separate ourselves from the competition.
RECTANGULAR DUCT + FITTINGS
More than just a welding shop, Madon Sheet Metal offers superior rectangular duct and fittings. We combine our small shop quality with a large shop’s capability. Our duct fabrication shop uses only G90 galvanized metal. We produce both S&D and TDC connections and stock interior duct insulation in ½”, 1”, 1½” thicknesses. Whether it’s galvanized, paint grip, PVC, stainless, or aluminum material we’ve got you covered. Our TDC ductwork comes standard with DuroDyne’s EZ Connector System that uses a lag bolt versus the traditional nut and bolt corner connection. This drastically cuts the field prep and installation time making connections easier and faster. We provide all required connectors and cleats with our ductwork and use Duro Dyne TDC clips and accessories. Our fittings are fabricated for installation. You will find our fittings are square, sealed by hand, and ready to easily install. Don’t settle for a sub par product; our ductwork is competitively priced, expertly fabricated, and above all the highest quality.
Madon Sheet Metal also offers a full line of duct and equipment accessories. All of our roof accessories come out of our welding shop and are made to last. We use the same heavy gauge standards as our welded duct, giving you a premium product. Contact us for more information on our linear box plenums, sub duct risers, curbs, self-leveling curbs, curb adapters, equipment rails, goose necks, weather caps, and more!
The Madon Sheet Metal Roof Equipment Rail is a mounting pedestal for roof-mounted HVAC equipment. Our Equipment Rails are fabricated out of 16 ga welded galvanized steel with an internal flange that spans the width of the wood, as well as an additional 1” interior flange to further reinforce the rail. A continuous wood nailer in screwed to the top of the rail and is covered by a 24 ga G90 counter flashing for attaching roofing material and insuring watertight installation. The base of the rail is also reinforced with a solid 16 gauge tack welded base. The base also includes a 2” flange all around for easy installation to the roof. The rails are custom-made to order and height and width are determined by the customer (DBC).
We also fabricate and ship union-made sub-duct risers nationwide. Call today for your quote!
The Madon Sheet Metal MSR sub duct riser is fabricated with a 24 gauge G90 galvanized sheet metal body and a 26 gauge G60 female start collar for vent connections. The MSR is produced in 4, 6, 8, and 10-inch round connection sizes. The MSR is Yellow Label Union Made by Sheet Metal Workers Local 73 members. The MSR allows installers to maintain an IBC 2006 compliant exhaust shaft rating for smoke and fire in kitchen, bathroom, and clothes dryer applications.
While providing a minimum 22-inch rise within the exhaust shaft, the MSR maintains a low profile. This results in less restriction, less noise, and lower velocity within the exhaust shaft itself. Our hemmed ½” flange all around the MSR allows for a strong connection to the inside wall of the exhaust shaft.
