Under the same load, a smaller cross-section of the profile can be selected, and the long-term operational stability is also better. The H-shaped steel has an H-shaped cross-section, with wide flanges and thin webs. Its bending resistance is improved by 5% to 10% compared to I-beams, and the connection processing is more convenient, which can save about 30% of the manufacturing cost.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-b165d27 e-flex e-con-boxed e-con e-parent\" data-id=\"b165d27\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-0768988 e-con-full e-flex e-con e-child\" data-id=\"0768988\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-2072d30 elementor-widget elementor-widget-image\" data-id=\"2072d30\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"700\" height=\"565\" src=\"https:\/\/jblstainless.com\/wp-content\/uploads\/2026\/07\/Q355B-H-Beam-Channel-6-12m-4-60mm-100-1000mm.png\" class=\"attachment-large size-large wp-image-3445\" alt=\"\" srcset=\"https:\/\/jblstainless.com\/wp-content\/uploads\/2026\/07\/Q355B-H-Beam-Channel-6-12m-4-60mm-100-1000mm.png 700w, https:\/\/jblstainless.com\/wp-content\/uploads\/2026\/07\/Q355B-H-Beam-Channel-6-12m-4-60mm-100-1000mm-15x12.png 15w, https:\/\/jblstainless.com\/wp-content\/uploads\/2026\/07\/Q355B-H-Beam-Channel-6-12m-4-60mm-100-1000mm-600x484.png 600w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-2be7185 e-con-full e-flex e-con e-child\" data-id=\"2be7185\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-64aa850 elementor-widget elementor-widget-text-editor\" data-id=\"64aa850\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"color: #ff6600;\">(H-Beam Section Dimension Explanation)<\/span> <br \/>The cross-sectional dimensions of H-shaped steel are usually expressed as H \u00d7 B \u00d7 t\u2081 \u00d7 t\u2082 \u00d7 L: <br \/>Example: H 400\u00d7200\u00d78\u00d713\u00d712m <br \/>Translation:<br \/>Expression:<\/p><ul><li>H = 400 mm \u2192 Steel section height (total section height)<\/li><li>B = 200 mm \u2192 Flange width<\/li><li>t\u2081 = 8 mm \u2192 Web thickness<\/li><li>t\u2082 = 13 mm \u2192 Flange thickness<\/li><li>L = 12 m \u2192 Length<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-3d08f5c e-flex e-con-boxed e-con e-parent\" data-id=\"3d08f5c\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-940ac59 e-con-full e-flex e-con e-child\" data-id=\"940ac59\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-ede46c9 elementor-widget elementor-widget-text-editor\" data-id=\"ede46c9\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Q355B is a high-strength low-alloy structural steel in accordance with China&#8217;s GB\/T 1591 standard.
