On painted steel posts, fitting a safety interlock switch means drilling, which drops metal swarf inside the guarded zone and breaks the powder coating where rust starts. On heavily used hinge doors, the leaf can sag until the interlock tongue no longer sits square in the switch body, and the PLC reads an unsafe door and stops the line. Alfence industrial safety fence uses T-slot aluminum profile posts so sensors, e-stops and cable routing bolt straight into the slot \u2013 no drilling, no swarf, no coating damage \u2013 and a reinforced hinge door frame that holds the interlock geometry over years of opening cycles. The result is fewer spurious stoppages, protected OEE, and a machine guarding fence that can still be reconfigured when the cell changes.<\/p>\n<figure class=\"sgf-hero-figure\">\n      <img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/safetyfencesystems.com\/wp-content\/uploads\/2026\/08\/wecom_media_1786382058799_2850689_1_7.webp\" alt=\"Cerca de seguran\u00e7a para rob\u00f4 industrial com perfis de alum\u00ednio, pain\u00e9is de malha soldada e equipamentos de automa\u00e7\u00e3o protegidos para prote\u00e7\u00e3o de c\u00e9lulas rob\u00f3ticas\"><br \/>\n    <\/figure>\n<p><a class=\"sgf-cta-btn\" href=\"\/pt\/contact\/\">Envie-nos o layout da sua c\u00e9lula para uma an\u00e1lise de prote\u00e7\u00e3o<\/a><\/p>\n<\/section>\n<section class=\"specs\" id=\"specs\">\n<h2>O cen\u00e1rio: os sensores s\u00e3o uma reflex\u00e3o tardia, e a cerca paga o pre\u00e7o<\/h2>\n<p class=\"sgf-pain-box\">Este \u00e9 o cl\u00e1ssico retrofit de automa\u00e7\u00e3o.
