A swinging door that wide sags, catches the wind and eats yard space. A top-hung sliding door solves this: the leaves hang from a heavy overhead track and slide clear of the opening, so the full width stays usable and nothing swings into traffic or weather.<\/p>\n          <p class=\"text-lead\">RAX builds each barn slider to your exact opening from galvanized steel leaves on a heavy rolling track, with the option of insulation, personnel pass doors and motorisation. Every unit is validated to 100,000 cycles in the RAX fatigue lab and shipped with technical drawings and an English manual so your local builder can install it without guesswork.<\/p>\n          <p class=\"text-muted\"><small>Cycle life of 100,000 cycles is validated in the RAX fatigue test lab. Wind performance is confirmed per project on the matching standard for your installed size and exposure; typical maximum leaf dimensions are industry-typical and confirmed on your specification.<\/small><\/p>\n        <\/div>\n        <div>\n          <h3>At a Glance<\/h3>\n          <ul class=\"list-check\">\n            <li>Top-hung sliding leaves \u2014 full opening stays clear, no swing into the yard.<\/li>\n            <li>Galvanized steel leaves resist farm corrosion and weather.<\/li>\n            <li>Heavy overhead track and rollers for wide, daily-use openings.<\/li>\n            <li>Optional insulation, personnel pass door and motorisation.<\/li>\n            <li>Built to your opening: any size, any RAL colour, custom engineered to your specification.<\/li>\n          <\/ul>\n        <\/div>\n      <\/div>\n    <\/div>\n  <\/section>\n\n  <!-- ===== 03 TECHNICAL SPECIFICATIONS ==================================== -->\n  <section class=\"section-dark section\">\n    <div class=\"container-xl\">\n      <div class=\"section-heading\">\n        <span class=\"eyebrow\">02 \u00b7 Technical Data<\/span>\n        <h2>Technical Specifications<\/h2>\n        <p class=\"lead\">Every door is engineered to your opening.

Leaves can be built with a 40\u201350 mm PU foam insulated core for livestock housing, workshops and temperature-sensitive stores, or left as single-skin galvanized steel for open machinery sheds where insulation is not needed. Insulated leaves also reduce condensation and draughts.<\/p><\/div>\n            <\/details>\n            <details>\n              <summary>Can you build it to my exact opening size?<\/summary>\n              <div class=\"faq-stack__answer\"><p>Yes.
