DELHI-SOLAC INC. is a major Canadian manufacturer specializing in mechanical and coated steel tubing. In 1991, the company became a subsidiary of Tubes Solac Ltd. and Cometic Technology Inc.

Tubes Solac Ltd. began its operations in April 1971 in Saint-Jérôme, Quebec. The plant occupied a surface area of 9,000 square feet. Two expansions were carried out for a total surface of 35,000 square feet for the manufacturing of mechanical tubing.

Cometic Technology Inc. was founded in 1961 in Delhi, Ontario by an American company called General Instruments Inc. Before the merger, its manufacturing space of 100,000 square feet and the rolling mills were used primarily for coated tubing.

By merging the two companies, DELHI-SOLAC was able to transfer the production technology for mechanical tubing to its Ontario plant. The combined sales forces of both divisions have allowed DELHI-SOLAC to penetrate the coated tubing market. Due to its sustained efforts in research and development, DELHI-SOLAC has added a colorless protective coating (acrylic lacquer) to its coated tubing for extra protection and durability.
