Tennessee Steel
read moreTriple-S's Knoxville Steel operation began in 1998. It serves Knoxville and the surrounding areas with a full line of structural and ornamental steel. Shearing, cutting and other processing services are also available from this facility. The Triple-S name does supply steel for bridges, stadiums, barges and large buildings but we still sell to "do-it-yourselfers, " too. For over 50 years, we have been known for creative supply solutions. While we may service thousands of customers, our founding principles remain the same-we take care of our customers like family.
