Hamlin Sheet Metal sales reps are an extension of company
Hamlin Sheet Metal, now in its 65th year in business, has chosen to market their spiral duct and flat-oval products through manufacturers’ representatives.
Spiral ductwork has become more and more of a commodity item. While at one time there were few manufacturers, now the access to spiral duct is more readily available than ever before.
However, the commodity item becomes unique when you add insulation, flanges, and mounting taps. The product becomes even more unique when you utilize any metal outside of galvanized or special gauges are required.
