SPEC SHEET

Steel Beams are widely used throughout the construction industry when supporting heavy loads is required. Commonly termed an “I” Beam because of its shape, beams provide great load bearing support when used horizontally or standing as columns. Available in two configurations, the most popular being the Wide Flange Steel Beam aka H Beam or W Beam with non-tapered flanges. This beam shape has a wider profile for added horizontal strength, making it ideal for skyscrapers or as a house beam, along with bridge beams, trailers, platforms, etc. Standard American Beams, aka Junior Beams or S Beams, have tapered flanges for added strength when your load is concentrated on the flanges, such as machine bases, hoists, cranes or a trolley beam for your garage.
