The multi-folded design creates a rigid, box-like structure that provides exceptional rigidity and resistance to bending forces.<\/li>\n<li>Load-Bearing Capacity: Offers exceptional strength and load-bearing capacity, exceeding many standard profiles. This makes it ideal for high-impact areas such as high-speed highways, sharp curves, and accident-prone sections.<\/li>\n<li>Structural Rigidity: The design ensures the post remains stable under heavy loads, preventing excessive movement or collapse during impacts, thus maintaining the guardrail\u2019s integrity.<\/li>\n<\/ul>\n<p>\u2705 High Flexibility &amp; Energy Absorption<\/p>\n<ul>\n<li>Controlled Deformation: The unique design allows for controlled deformation during collisions. Unlike rigid posts that may break or buckle catastrophically, the sigma profile is engineered to fold and crumple in a predictable manner.<\/li>\n<li>Energy Dissipation: This controlled deformation enables better absorption and distribution of kinetic energy from the impact. The post dissipates the vehicle\u2019s energy gradually, reducing the peak forces transferred to the vehicle and its occupants.<\/li>\n<li>Enhanced Road Safety: By absorbing impact energy and minimizing vehicle rebound, the SIGMA POST helps to reduce the severity of crashes, lower the risk of secondary accidents, and improve overall road safety.<\/li>\n<\/ul>\n<p>\u2705 Corrosion Protection<\/p>\n<ul>\n<li>Galvanized Coating: Finished with a high-quality galvanized coating, providing excellent resistance to rust and corrosion.<\/li>\n<li>Durability in Outdoor Conditions: The coating protects the post from environmental factors such as moisture, UV rays, and chemical pollutants. This ensures the structural integrity and appearance of the post are maintained over its service life.<\/li>\n<li>Reduced Maintenance: The corrosion-resistant finish significantly extends the post\u2019s service life, minimizing the need for maintenance, painting, or replacement, even in challenging outdoor environments.<\/li>\n<\/ul>\n<p><img alt=\"\" decoding=\"async\" class=\"size-full wp-image-7764 aligncenter\" src=\"http:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/9.webp\" width=\"546\" height=\"449\" srcset=\"https:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/9.webp 546w, https:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/9-300x247.webp 300w, https:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/9-15x12.webp 15w\" sizes=\"(max-width: 546px) 100vw, 546px\" \/><\/p>\n<p><strong><b>1<\/b><\/strong><strong><b>.3 Typical Specifications (Common Industry Standards)<\/b><\/strong><\/p>\n<div class=\"wp-responsive-table\">\n<table>\n<tbody>\n<tr>\n<td><strong><b>\u0627\u0644\u0645\u0639\u0644\u0645\u0629<\/b><\/strong><\/td>\n<td><strong><b>Details<\/b><\/strong><\/td>\n<\/tr>\n<tr>\n<td>\u0627\u0644\u0645\u0648\u0627\u062f<\/td>\n<td>Q235B \/ S235JR steel (cold-formed and high-frequency welded)<\/td>\n<\/tr>\n<tr>\n<td>\u0627\u0644\u0637\u0644\u0627\u0621<\/td>\n<td>Hot-dip galvanized or pre-galvanized, zinc layer thickness \u2265 85 \u03bcm<\/td>\n<\/tr>\n<tr>\n<td>Section Sizes<\/td>\n<td>Standard sigma profiles, e.g., 140\u00d760\u00d74mm, 150\u00d770\u00d74mm, customized available<\/td>\n<\/tr>\n<tr>\n<td>\u0627\u0644\u0637\u0648\u0644<\/td>\n<td>1.5m to 2.5m, or as per customer design requirements<\/td>\n<\/tr>\n<tr>\n<td>Standards<\/td>\n<td>Compliant with EN 1317, EN 10346, or other regional road safety standards<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p><img alt=\"\" decoding=\"async\" class=\"size-full wp-image-7765 aligncenter\" src=\"http:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/11-1.webp\" width=\"669\" height=\"488\" srcset=\"https:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/11-1.webp 669w, https:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/11-1-300x219.webp 300w, https:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/11-1-16x12.webp 16w, https:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/11-1-600x438.webp 600w\" sizes=\"(max-width: 669px) 100vw, 669px\" \/><\/p>\n<p><strong><b>1<\/b><\/strong><strong><b>.4 Key Applications<\/b><\/strong><\/p>\n<ul>\n<li>High-speed highways and motorways<\/li>\n<li>High-risk road sections (curves, intersections, steep grades)<\/li>\n<li>Heavy-vehicle lanes and truck routes<\/li>\n<li>Areas with a history of frequent accidents<\/li>\n<li>Projects prioritizing advanced crash safety performance<\/li>\n<\/ul>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>SIGMA POST (Sigma-Shaped Steel Guardrail Post) is a high-strength steel support post engineered for highway guardrail and crash barrier systems.
