About Us

About Steel Tube Institute

The Steel Tube Institute was formed in 1930 when a group of manufacturers joined forces to promote and market steel tubing. Their goal was to mount a cooperative effort that would improve manufacturing techniques and inform downstream customers about their products’ utility and versatility.  Today our goal is the same. STI is dedicated to advancing the growth and competitiveness of North America’s steel tubular products. By representing the manufacturers of steel tubes and those in affiliated industries, our strength is bringing together resources to move the industry forward through active collaboration.  We accomplish this by effective promotion, education and problem solving targeting all trades from architects and owners to field installers.
