Hamlin Sheet Metal of Garner, North Carolina, was awarded the contract to provide the spiral duct on the addition and remodel at F.K. Marchman Technical Educational Center in New Port Richey, Florida.

The HVAC construction project was all paint-grip material, single-wall and double-wall duct. The customer chose to use Hamlin’s wedge gasket and Hamlin’s self-sealing spiral duct on the single-wall material.

Hamlin’s manufacturer’s representative in that territory is Stan Weaver and Co. of Tampa, Florida. The mechanical contractor was RoyalAire Mechanical Services Inc. Anston-Greenlees was mechanical engineer and Creative Contractors Inc. was general contractor.

On the double-wall portion of the project, RoyalAire used Hamlin’s flange system for double-wall duct.

“The Hamlin flange made the flat-oval, double-wall spiral much faster to install in the field,” said project manager Gabe DiGennaro.
The duct arrived with the flanges factory installed and sealed. It was ready to hang. Factory slots were cut at the factory to be ready to accept the radius grilles. To avoid additional transverse joint connections, round taps had manifolds factory-installed to spiral duct sections. 

Lance Wooles of Stan Weaver said Hamlin had been great to work with. 

“It starts with getting the quote out correctly and in a timely manner,” Wooles said. “Then the CADs, the coordination of delivery dates and times, and last but certainly not least, a quality product delivered. We find all of this in working with Hamlin on this job, and others.”
