Ils se ressemblent \u00e0 premi\u00e8re vue, mais ils ne sont pas \u00e9quivalents&nbsp;: selon leur mode de fabrication, ils conviennent \u00e0 un usage ou \u00e0 un autre. Cet article passe en revue leurs caract\u00e9ristiques, les principaux types et leur r\u00f4le dans la s\u00e9curit\u00e9 en toiture.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Qu\u2019est-ce qu\u2019un grillage m\u00e9tallique&nbsp;?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Un grillage m\u00e9tallique est une structure form\u00e9e de fils ou de lames de m\u00e9tal entrelac\u00e9s, soud\u00e9s ou d\u00e9coup\u00e9s, qui laissent entre eux des ouvertures r\u00e9guli\u00e8res. Il est fabriqu\u00e9 en acier (galvanis\u00e9, inoxydable ou au carbone), en aluminium ou dans d\u2019autres alliages, et sert \u00e0 clore, prot\u00e9ger, filtrer, renforcer ou contenir.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Caract\u00e9ristiques et \u00e9l\u00e9ments d\u2019un grillage m\u00e9tallique<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Pour bien choisir, il faut conna\u00eetre les \u00e9l\u00e9ments d\u2019un grillage m\u00e9tallique et les caract\u00e9ristiques qui conditionnent son comportement&nbsp;:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mat\u00e9riau&nbsp;: d\u00e9termine la r\u00e9sistance m\u00e9canique et la r\u00e9sistance \u00e0 la corrosion (acier galvanis\u00e9, inoxydable ou aluminium).<\/li>\n\n\n\n<li>Diam\u00e8tre du fil ou \u00e9paisseur&nbsp;: plus le fil est \u00e9pais, plus la r\u00e9sistance est \u00e9lev\u00e9e.<\/li>\n\n\n\n<li>Ouverture de maille&nbsp;: dimension de l\u2019ouverture entre les fils.<\/li>\n\n\n\n<li>Type d\u2019assemblage&nbsp;: soudure, torsion ou tissage. Il d\u00e9termine la rigidit\u00e9 et la capacit\u00e9 de d\u00e9formation.<\/li>\n\n\n\n<li>Traitement de surface&nbsp;: la galvanisation, la plastification ou la peinture peuvent prolonger sa durabilit\u00e9.<\/li>\n\n\n\n<li>Conditionnement&nbsp;: rouleaux ou panneaux, selon l\u2019application.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Types de grillages m\u00e9talliques selon leur fabrication<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Grillage simple torsion<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Les fils s\u2019entrelacent en spirale pour former des losanges. Il est souple, l\u00e9ger et c\u2019est le plus \u00e9conomique. Il est g\u00e9n\u00e9ralement pos\u00e9 sur des terrains, dans des jardins ou sur chantier pour d\u00e9limiter un espace quelconque.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Treillis soud\u00e9<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Il est form\u00e9 de fils longitudinaux et transversaux soud\u00e9s \u00e0 chaque croisement, ce qui le rend rigide et stable. Il est utilis\u00e9 dans les armatures de b\u00e9ton, les cl\u00f4tures, les cages et les protections de machines.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Grillage triple torsion<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Avec un entrelacement de trois tours \u00e0 chaque jonction, il se compose d\u2019hexagones tr\u00e8s r\u00e9sistants qui ne se d\u00e9maillent pas, m\u00eame si un fil casse. Il est employ\u00e9 dans les gabions, la protection de talus et les ouvrages de g\u00e9nie civil.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">M\u00e9tal d\u00e9ploy\u00e9<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Il est obtenu en d\u00e9coupant et en \u00e9tirant une t\u00f4le m\u00e9tallique sans perte de mati\u00e8re, de sorte qu\u2019il ne comporte aucune jonction. Tr\u00e8s r\u00e9sistant et antid\u00e9rapant, il est utilis\u00e9 dans les passerelles, les plateformes, les cl\u00f4tures et les fa\u00e7ades.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Toile m\u00e9tallique tiss\u00e9e<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Fabriqu\u00e9e en entrela\u00e7ant des fils m\u00e9talliques comme dans un tissu, elle permet des ouvertures tr\u00e8s pr\u00e9cises. C\u2019est la toile retenue pour le criblage, la filtration et le tamisage dans l\u2019industrie, les mines et l\u2019agroalimentaire.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Grillage m\u00e9tallique de s\u00e9curit\u00e9 pour toitures et lanterneaux<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Dans les travaux en hauteur, le grillage m\u00e9tallique de s\u00e9curit\u00e9 emp\u00eache les chutes \u00e0 travers des surfaces fragiles comme les lanterneaux, les coupoles ou les toitures en fibrociment. Ces grillages se posent sur ou sous la couverture et doivent \u00eatre con\u00e7us pour retenir la chute d\u2019une personne, tout en r\u00e9sistant aux intemp\u00e9ries. C\u2019est pourquoi ils sont fabriqu\u00e9s en acier haute r\u00e9sistance avec des traitements anticorrosion, et con\u00e7us pour une installation simple et durable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Il ne faut pas confondre les grillages de s\u00e9curit\u00e9 avec les filets de s\u00e9curit\u00e9&nbsp;: ce sont deux produits aux fonctions et aux normes diff\u00e9rentes. Une zone \u00e9quip\u00e9e d\u2019un grillage peut en outre \u00eatre compl\u00e9t\u00e9e par un garde-corps. Le grillage prot\u00e8ge la surface fragile et le garde-corps le p\u00e9rim\u00e8tre&nbsp;; les deux sont compatibles et assurent une meilleure protection.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Grillages antichute PIGNUS de YPSOS SAFETY<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Parmi les solutions de protection collective, les grillages antichute PIGNUS de YPSOS SAFETY, fabriqu\u00e9s en Espagne, prot\u00e8gent les surfaces fragiles en toiture, comme les lanterneaux, les coupoles et les panneaux translucides. Ils sont con\u00e7us et essay\u00e9s conform\u00e9ment \u00e0 la norme NF-EN 14963, avec une r\u00e9sistance de 1\u00a0500\u00a0J. Ils sont compos\u00e9s d\u2019un fil d\u2019acier tr\u00e9fil\u00e9 dur de 2,05\u00a0mm, avec une ouverture de maille de 55\u00a0mm.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ils sont fournis en rouleaux de 25&nbsp;m de longueur, en largeurs de 1&nbsp;250&nbsp;mm et 1&nbsp;500&nbsp;mm, fixations sur t\u00f4le incluses (\u00e9paisseur minimale de la t\u00f4le&nbsp;: 0,5&nbsp;mm).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Si vous \u00e9valuez comment prot\u00e9ger une toiture, consultez l\u2019\u00e9quipe de YPSOS SAFETY pour choisir le mod\u00e8le adapt\u00e9.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-fe48e5de wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button is-style-fill\"><a class=\"wp-block-button__link has-background has-medium-font-size has-custom-font-size wp-element-button\" href=\"https:\/\/ypsossafety.com\/fr\/contactez-le-fabricant-de-systemes-de-securite-en-hauteur\/\" style=\"background-color:#ff7514\">Contactez-nous pour plus d&rsquo;informations<\/a><\/div>\n<\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Questions fr\u00e9quentes sur les types de grillages et leurs diff\u00e9rences<\/h2>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1794216156991\"><strong class=\"schema-faq-question\">Quels sont les types de grillages ?<\/strong> <p class=\"schema-faq-answer\">Selon leur fabrication, les principaux sont le treillis soud\u00e9, le grillage simple torsion, le grillage triple torsion, le m\u00e9tal d\u00e9ploy\u00e9 et la toile m\u00e9tallique tiss\u00e9e.
