Structural bolting assemblies are used to create connections for steel structures, industrial buildings, bridges, infrastructure and civil engineering works where joint behaviour is a fundamental element of structural safety.<\/p>\n

Unlike traditional mechanical fasteners, these systems are governed by specific standards that define dimensional characteristics, mechanical properties, markings and methods of use.<\/p>\n

The main European reference standards are UNI EN 15048<\/strong>, relating to non-preloaded structural bolting assemblies, and UNI EN 14399<\/strong>, dedicated to high-strength structural bolting assemblies suitable for preloading.<\/p>\n

EFS can support supplies of standard and special structural bolting assemblies for industrial and infrastructure applications, coordinating materials, surface treatments and technical documentation according to the required specifications. This approach is consistent with the EFS operating model based on European production, material traceability and supply certifications.<\/p>\n<\/div><\/div><\/div>
