Every row below is one wage determination line: a sheet metal worker classification, in one county, for one construction type, under one funding source. The rate that applies to your project is the row whose county, construction type and funding source all match it — a Highway rate does not apply to a Building project in the same county, and a state determination does not substitute for a federal one.
Sheet metal workers fabricate and install ductwork, architectural metal, flashing and metal roofing. On mechanical-heavy projects the sheet metal rate governs HVAC duct installation, which is often confused with the pipefitter classification that covers the piping side of the same system.
Prevailing wage is set county by county. These are the New Hampshire counties with sheet metal worker records in the set above — open one to see every classification on that county's determination, not just this trade.

Across the 10 federal-funded determination records WageFinder lists for sheet metal workers in New Hampshire, total prevailing wage runs from $30.34 to $50.59 per hour, median $40.29. There is no single statewide figure: each county's determination sets its own rate, and the same county can carry different rates for Building, Highway, Heavy and Residential work.
The total prevailing wage shown is the base hourly rate plus the fringe benefit rate. Of the 10 New Hampshire records on this page, 10 list a fringe amount separately, with a median of $11.89 per hour — roughly 30% of the median total. The rest list no separate fringe, meaning the base rate is the whole obligation. Fringe can be paid as bona fide benefit plan contributions, as cash added to the paycheck, or as a mix of both.
