Custom Metals, founded in 1974, is an industry leader in sheet metal and plate fabrication, installation and maintenance. Custom Metals serves a broad range of industries including steel, power, cement, pulp and paper, food processing and petrochemical.

From its origin as a HVAC fabricator, Custom has grown into one of the largest heavy plate fabricators in the country. Although Custom Metals continues to operate a large HVAC shop, our heavy plate fabrication shop has become the largest part of our business. This shop excels at fabricating large difficult projects such as elevated ductwork, hoppers, and pressure vessels.

When we are fabricating large complex plate projects, whether required by the contract or not, we will shop assemble all pieces to ensure that once delivered the pieces will fit. We will offer value engineering ideas to assist during fabrication, transport, and the erection of the fabricated material. We also offer field assembly of our shop fabricated platework. Through another division of Lexicon, Schueck Steel, we also offer complete installation of our fabricated platework.
