The temperature just a few centimetres inside the timber beam is only 40\u00b0C, compared with nearly 1,000\u00b0C on the outside.<br \/>Fire and heat do not alter the mechanical strength. Collapse occurs when combustion reduces the cross-sectional area to such an extent that the beam can no longer fulfil its load-bearing function. The beam\u2019s load-bearing capacity is proportional to its thickness; therefore, high loads and strength can only be maintained by oversizing the beam without the need for treatments such as intumescent or fire-retardant paints, plaster or calcium silicate boards.<\/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\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t<div class=\"swiper-slide\" data-slide=\"2\" role=\"group\" aria-roledescription=\"slide\" aria-label=\"2 of 3\">\n\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-85d1d61 e-flex e-con-boxed e-con e-child\" data-id=\"85d1d61\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-85d6bfb elementor-widget elementor-widget-image\" data-id=\"85d6bfb\" 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 decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2026\/06\/GFK-Website-Firewall_2026-26-150x150.webp\" class=\"attachment-thumbnail size-thumbnail wp-image-15840\" alt=\"\" srcset=\"https:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2026\/06\/GFK-Website-Firewall_2026-26-150x150.webp 150w, https:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2026\/06\/GFK-Website-Firewall_2026-26-300x300.webp 300w, https:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2026\/06\/GFK-Website-Firewall_2026-26.webp 401w\" sizes=\"(max-width: 150px) 100vw, 150px\" \/>\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 class=\"elementor-element elementor-element-cb73e25 elementor-widget elementor-widget-heading\" data-id=\"cb73e25\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">STEEL<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d998488 elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"d998488\" 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>Steel is considered a non-combustible material, and this is absolutely true, but it is also an excellent conductor of heat. When subjected to a drastic rise in temperature, as in the case of a fire, steel rapidly loses its stability.<br \/>After just 5 minutes of exposure to fire, steel reaches a temperature of around 500\u00b0C. This represents the so-called critical temperature for this material. After 10 minutes of fire, the steel structure yields and collapses in on itself like a house of cards. Steel expands by approximately 0.012 mm for every metre of length and degree of temperature. This means, at a temperature of 500\u00b0C, an elongation of 6 mm per metre. The use of intumescent paints or other types of protection is mandatory.<\/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\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t<div class=\"swiper-slide\" data-slide=\"3\" role=\"group\" aria-roledescription=\"slide\" aria-label=\"3 of 3\">\n\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-4a059ee e-flex e-con-boxed e-con e-child\" data-id=\"4a059ee\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-13d6dd2 elementor-widget elementor-widget-image\" data-id=\"13d6dd2\" 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 decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2026\/06\/GFK-Website-Firewall_2026-27-150x150.webp\" class=\"attachment-thumbnail size-thumbnail wp-image-15841\" alt=\"\" srcset=\"https:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2026\/06\/GFK-Website-Firewall_2026-27-150x150.webp 150w, https:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2026\/06\/GFK-Website-Firewall_2026-27-300x300.webp 300w, https:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2026\/06\/GFK-Website-Firewall_2026-27.webp 401w\" sizes=\"(max-width: 150px) 100vw, 150px\" \/>\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 class=\"elementor-element elementor-element-68f1cac elementor-widget elementor-widget-heading\" data-id=\"68f1cac\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">CONCRETE<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-eef39b4 elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"eef39b4\" 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>Due to its composition, reinforced concrete or simply cement is also classified as a non-flammable building material. The thermal conductivity of concrete is 2.1 W\/mk, compared with 60 W\/mK for steel \u2013 a factor that should not be overlooked when dealing with reinforced concrete components and, in particular, prestressed concrete.<br \/>Limestone aggregates do not undergo any appreciable reduction in mechanical strength until temperatures exceed 750\u00b0C, at which point the thermal decomposition of limestone into lime and carbon dioxide begins. The problem lies in the steel content within the structure, and the key factor is the thermal protection of the concrete cover. Indeed, in reinforced concrete structures, high temperatures are of particular significance, especially with regard to the steel, which loses most of its properties at temperatures above 500\u00b0C.<br \/>These weak points become preferential pathways for heat flow, capable of causing a localised rise in temperature that can exceed 500\u00b0C in a very short time. In this case too, the fire behaviour is similar to that of a steel beam, so it is mandatory to use intumescent paints or other types of protection.<\/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\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<div
