You will instantly get the admissible load in kg\/m\u00b2 for each available height and thickness, calculated per the <strong>L\/200<\/strong> criterion of <a href=\"https:\/\/eurocodes.jrc.ec.europa.eu\" target=\"_blank\" rel=\"noopener noreferrer\">Eurocode 3 (EC3)<\/a>.<\/div>\r\n <\/div>\r\n <div class=\"faq-item\">\r\n <button class=\"faq-q\" onclick=\"toggleFaq(this)\" aria-expanded=\"false\">Which profile do I need for a load of X kg\/m\u00b2 with a span of Y metres?<span class=\"faq-icon\">+<\/span><\/button>\r\n <div class=\"faq-a\">Select the profile family, enter the spacing parameters and type your load in the <strong>reference load<\/strong> field. The calculator marks valid profiles with <strong>\u2713 green<\/strong>, those at the limit with <strong>~ yellow<\/strong> and insufficient ones with <strong>\u2717 red<\/strong>.

The self-weight of the profile, insulation and finishes must be added separately to obtain the total design load.<\/div>\r\n <\/div>\r\n <div class=\"faq-item\">\r\n <button class=\"faq-q\" onclick=\"toggleFaq(this)\" aria-expanded=\"false\">What portal spacing is typical in industrial buildings?<span class=\"faq-icon\">+<\/span><\/button>\r\n <div class=\"faq-a\">In standard industrial buildings in Spain, the most common spacing is <strong>5 to 7 metres<\/strong>. The <a href=\"https:\/\/magon.es\/productos\/correas-mg-c-y-mg-z\/\" target=\"_blank\" rel=\"noopener noreferrer\">MG C and Z purlins<\/a> have data for spacings from 4 to 9 m.

This allows up to 35% more load than the equivalent C-purlin. Where possible, it is recommended to install Z-purlins continuously over at least 2 spans.<\/div>\r\n <\/div>\r\n <div class=\"faq-item\">\r\n <button class=\"faq-q\" onclick=\"toggleFaq(this)\" aria-expanded=\"false\">When should I use MG 40\/250 instead of MG 30\/206?<span class=\"faq-icon\">+<\/span><\/button>\r\n <div class=\"faq-a\">The <a href=\"https:\/\/magon.es\/productos\/mg-40-250\/\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>MG 40\/250<\/strong><\/a> has greater inertia (40 mm rib vs 30 mm).
