Steel tees can be bent with the stem out, with the stem in, or with the stem up. Steel mills produce some sizes of steel tees (usually the smaller sizes), but more often tees are created by splitting beams longitudinally by either using a rotary shear or flame cutting. After cutting, the release of residual stresses usually results in steel tees that are curved in at least one plane and often in two planes. These shapes are subsequently bent back into straight sections or bent to the radius specified for its application. Chicago Metal Rolled Products has developed the technology to bend the largest steel tees with minimum distortion to very tight tolerances. The easiest steel tees to bend are stem out; stem in and stem up are more difficult. As you can imagine, the stem of tees rolled stem-in is going to want to ripple as it is compressed, and the longer the stem, the more difficult the bending process is. We have the ability to eliminate that problem of ripples and provide perfectly flat stems on even the largest stem-in tees.
We can cut, bevel, trim, drill, grind and deburr steel tees as well as have them blasted and painted. We can ship large tees to the job site for field erected tanks ready for installation.
When steel tees are used as stiffeners on the outside of curved plate, they are usually rolled stem-in. When used as stiffeners on the inside of curved plate, they are usually rolled stem out. Because our stem-in tees have flat stems, our customers can use automatic welding equipment to weld the tees to plate. (Wavy tees would not allow for automatic welding.) Stem up steel tees can be used as a base plate or a lintel curved in plan.
Construction applications include parts for roof trusses, canopies, and curved lintels. Equipment applications include parts for agricultural and construction equipment, tank supports, and other component parts of machinery.
