The door panels fold vertically (stacking above the opening) or horizontally (accordion-style), consuming minimal wall or ceiling space compared to sliding alternatives. This makes folding doors the preferred solution for aircraft hangars, helicopter pads, agricultural machine sheds, boat houses, and industrial buildings where overhead clearance must be preserved.<\/p>\n <p>As a pure manufacturer since 1999 with a 11,000 m&sup2; production base, 170+ staff, and 20+ R&amp;D engineers, RAX produces each folding door to your exact opening dimensions &mdash; from a single unit, with no minimum order. Every door is factory-tested against a 100,000-cycle fatigue protocol and shipped with complete wiring diagrams, and English manuals for your local installation team. <span class=\"rax-tag\">[SOURCED &mdash; RAX claim]<\/span><\/p>\n <p>In the global market, bi-fold hangar door specialists such as Schweiss (US) build folding doors up to 120&nbsp;ft (~36.6&nbsp;m) width using lift straps, hydraulic cylinders, or bottom drive motors, with cladding options including wood, translucent panels, and built-in windows. <span class=\"rax-tag\">[SOURCED: bifold.com]<\/span> Hangar span classes range from &lt;&nbsp;30&nbsp;m (S) to &gt;&nbsp;120&nbsp;m (XXL). <span class=\"rax-tag\">[SOURCED: Wikipedia]<\/span> RAX offers both vertical bi-fold and horizontal bi-fold configurations, custom-engineered to your span and wind-load requirements. <span class=\"rax-tag\">[SOURCED &mdash; RAX claim]<\/span><\/p>\n <\/div>\n <div class=\"page-actions\" style=\"margin-top:2rem;\">\n <a class=\"btn btn-primary\" href=\"https:\/\/www.raxdoors.com\/contact-us\/\">Get a Free Quote<\/a>\n<\/div>\n <\/div>\n <\/section>\n\n <section class=\"section-dark section\">\n <div class=\"container-xl\">\n <div class=\"section-heading\">\n <span class=\"eyebrow\">02 \u00b7 Key Features<\/span>\n <h2>Key Features &amp; Benefits<\/h2>\n <\/div>\n <div class=\"divider\"><\/div>\n\n <div class=\"flow-top-lg\">\n <div class=\"grid-3\">\n <div class=\"card\"><h3>Space-Saving Bi-Fold Design<\/h3><p>Panels fold vertically or horizontally, consuming minimal wall run-back or headroom.
