Universal Beams - 254x146x31

Steel universal beams (UBs), often called "I-beams," are structural steel bars with a cross-section shaped like the letter "I". They feature a vertical central section (the web) and two horizontal flat plates at the top and bottom (the flanges) that are perfectly parallel to each other. The web is designed to resist vertical shearing forces, while the long flanges provide exceptional strength against bending under heavy loads. Because they are highly efficient at carrying weight across long spans with minimal bending, they are the go-to choice for main structural supports, floor joists, and roof beams in modern commercial and residential buildings.
