When a beam bends under load, the highest stress occurs at the points farthest from the centre of the section. In an I-beam most of the steel is placed in the flanges, exactly at those far points, so high bending resistance is achieved with less steel. The web carries the shear force.<\/p>\n<figure class=\"tfs-fig\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-2908\" src=\"https:\/\/tfstrading.com\/wp-content\/uploads\/2026\/10\/tfs-ibeam-stack.webp\" alt=\"End view of wide-flange steel beams in a stockyard\" width=\"1200\" height=\"675\" loading=\"lazy\" srcset=\"https:\/\/tfstrading.com\/wp-content\/uploads\/2026\/10\/tfs-ibeam-stack.webp 1200w, https:\/\/tfstrading.com\/wp-content\/uploads\/2026\/10\/tfs-ibeam-stack-300x169.webp 300w, https:\/\/tfstrading.com\/wp-content\/uploads\/2026\/10\/tfs-ibeam-stack-1024x576.webp 1024w, https:\/\/tfstrading.com\/wp-content\/uploads\/2026\/10\/tfs-ibeam-stack-768x432.webp 768w, https:\/\/tfstrading.com\/wp-content\/uploads\/2026\/10\/tfs-ibeam-stack-64x36.webp 64w, https:\/\/tfstrading.com\/wp-content\/uploads\/2026\/10\/tfs-ibeam-stack-108x61.webp 108w, https:\/\/tfstrading.com\/wp-content\/uploads\/2026\/10\/tfs-ibeam-stack-118x66.webp 118w, https:\/\/tfstrading.com\/wp-content\/uploads\/2026\/10\/tfs-ibeam-stack-124x70.webp 124w, https:\/\/tfstrading.com\/wp-content\/uploads\/2026\/10\/tfs-ibeam-stack-245x138.webp 245w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption>End view of steel beams; the two horizontal flanges and the vertical web are clearly visible.<\/figcaption><\/figure>\n<h2 id=\"types\">Types of I-beam<\/h2>\n<div class=\"tfs-cards\">\n<div class=\"tfs-card\"><b>IPE beam<\/b><span>Parallel flanges of constant thickness, with a depth of roughly twice the flange width.
