Rain gutters have been a part of building design for centuries. Virtually every home needs rain gutters. Sections of gutter and downspouts were once made from sheet metal and assembled as a gutter system to a house. Almost 60 years ago people began applying roll forming to the manufacture of rain gutters. The seamless rain gutter was born. Gutter material is sold in coils. The drive system of the gutter machine pulls the flat material through a series of stages.
