Steel Beams W 4 x 13 lb (4.16" x .280" x 4.06") A572/A99

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
