Thor-Weld Industries was incorporated in 1972. In the early years our core business was steel and aluminum fabrication. After fifteen years of business an industrial caster company was purchased. The company then separated into two divisions, Rampmaster and Thorcasters.

The caster division did a combination of both manufacturing from raw material and importing caster parts. The second division, Rampmaster, concentrated on the manufacturing of ramps both steel and aluminum.
