Beams typically support floor or roof elements and bear upon columns or walls. They can be fabricated in many shapes and sizes such as Rectangular Beams, Inverted Tee Beams, "L" Beams, and Scissor Beams. Each shape can be fabricated in a wide variety of sizes to meet the project requirements. Prestress strand is commonly used to reinforce long Rectangular, "L" and Inverted Tee Beams, while Scissor Beams use mild reinforcement.
