Introduction: Lightweight Structural Replacement for Steel<\/h2>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">In modern structural engineering, reducing dead load while maintaining load-bearing performance is a key design priority. <strong><a href=\"https:\/\/www.mingchifrp.com\/ko\/product-category\/frp-profiles\/frp-i-beam\/\" data-type=\"link\" data-id=\"https:\/\/www.mingchifrp.com\/product-category\/frp-profiles\/frp-i-beam\/\">FRP I\ud615\uac15<\/a><\/strong> (Fiberglass Reinforced Polymer I-Beam) has emerged as a reliable alternative to traditional steel beams in corrosive, heavy-duty, and maintenance-sensitive environments.<\/p>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">Compared with steel, FRP I-Beams can reduce structural weight by up to 75%, while offering long-term durability without rust, coating degradation, or frequent maintenance. This makes them especially suitable for infrastructure where lifecycle cost and corrosion resistance are critical design factors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-left\">2. Mechanical Properties: Key Engineering Performance Data<\/h2>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">FRP I-Beams are engineered composite profiles designed for predictable structural performance. Typical mechanical properties include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Tensile Strength:<\/strong> 200 \u2013 350 MPa<\/li>\n\n\n\n<li><strong>Flexural Strength (Bending Strength):<\/strong> 250 \u2013 450 MPa<\/li>\n\n\n\n<li><strong>Compressive Strength:<\/strong> 150 \u2013 300 MPa<\/li>\n\n\n\n<li><strong>Shear Strength:<\/strong> 30 \u2013 80 MPa<\/li>\n\n\n\n<li><strong>Elastic Modulus:<\/strong> 10 \u2013 25 GPa<\/li>\n\n\n\n<li><strong>Density:<\/strong> ~1.8 \u2013 2.0 g\/cm\u00b3<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Strength-to-Weight Advantage vs Steel<\/h3>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">While steel has a higher elastic modulus (~200 GPa), FRP I-Beams compensate through:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Extremely low density (\u22481\/4 of steel)<\/li>\n\n\n\n<li>High corrosion resistance<\/li>\n\n\n\n<li>Improved strength-to-weight efficiency in non-extreme deflection-critical spans<\/li>\n<\/ul>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">This makes <strong><a href=\"https:\/\/www.mingchifrp.com\/ko\/frp-in-modern-construction\/\" data-type=\"link\" data-id=\"https:\/\/www.mingchifrp.com\/frp-in-modern-construction\/\">FRP structural systems<\/a><\/strong> ideal for secondary structural systems, platforms, walkways, and support frames.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-left\">3.
