Built to solve the hard part
Sweetwater Metal Products was founded in 1969. In 1995, an idea for a machine to straighten coiled HDPE pipe was developed in the SMP shop—technology that would become the McElroy LineTamer®.
Today, the company focuses its experience on purpose-built HDPE pipe handling equipment for utility companies and installation contractors.
