It offers tested resistance to explosion overpressures of up to 3 bar (300 kPa \/ 45 psi). This makes it particularly suitable for bunkers, shelters, military facilities, and critical infrastructure.  <\/p>\n<p>The solid steel construction is based on a proven security concept from the vault-building industry. The door was tested by Fraunhofer EMI and meets the requirements of resistance class EPR4 according to EN 13123-1. As a result, the BD-3 offers a high-performance solution for access points that may be exposed to high dynamic loads caused by explosions. <\/p>\n<h2>Design and Explosion Protection<\/h2>\n<p>The door panel is made of solid steel that is 20 mm thick. This design ensures high rigidity and resistance to deformation. At the same time, the robust construction ensures reliable operation under demanding conditions.  <\/p>\n<p>The door is locked using a sturdy 2-point locking mechanism. Solid flat bolts with a cross-section of 20 \u00d7 60 mm press the door panel against the perimeter seals. This ensures a secure lock and improved sealing.  <\/p>\n<p>In addition, the BD-3 explosion-proof door features a particularly robust hinge design. Both the hinges and the locking mechanism can be completely disassembled. This simplifies transport, installation, and future maintenance.  <\/p>\n<h2>Waterproofing and Surface Treatment<\/h2>\n<p>Perimeter seals improve the seal between the door panel and the frame. This provides additional protection against external influences. <\/p>\n<p>The surface is coated with a corrosion-resistant primer. This serves as the base for an additional powder coating in the desired color. This allows the door to be visually adapted to the requirements of the specific building.<\/p>\n<div class=\"row\"  id=\"row-921175621\">\n\n\t<div id=\"col-799465350\" class=\"col medium-6 small-12 large-6\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n<h2>Technical Data<\/h2>\n<ul>\n<li><strong>Model:<\/strong> BD-3<\/li>\n<li><strong>Product Type:<\/strong> Explosion-Proof Steel Door<\/li>\n<li><strong>Explosion resistance:<\/strong> 3 bar (300 kPa \/ 45 psi)<\/li>\n<li><strong>Resistance Class:<\/strong> EPR4 according to EN 13123-1<\/li>\n<li><strong>Testing Institute:<\/strong> Fraunhofer EMI<\/li>\n<li><strong>Door panel thickness:<\/strong> 20 mm<\/li>\n<li><strong>Door panel material:<\/strong> Solid sheet steel<\/li>\n<li><strong>Locking mechanism:<\/strong> 2-point locking<\/li>\n<li><strong>Flat bar:<\/strong> 20 \u00d7 60 mm<\/li>\n<li><strong>Hinges:<\/strong> Sturdy, removable design<\/li>\n<li><strong>Clear opening:<\/strong> 900 \u00d7 2,000 mm<\/li>\n<li><strong>Minimum required wall opening:<\/strong> 1,055 \u00d7 2,100 mm<\/li>\n<li><strong>External dimensions:<\/strong> 1,156 \u00d7 2,218 mm<\/li>\n<li><strong>Weight:<\/strong> approx. 425 kg<\/li>\n<li><strong>Sealing:<\/strong> Perimeter seals<\/li>\n<li><strong>Surface:<\/strong> Corrosion-resistant primer, prepared for powder coating<\/li>\n<\/ul>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n\n\t<div id=\"col-393621221\" class=\"col medium-6 small-12 large-6\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n\t<div class=\"img has-hover x md-x lg-x y md-y lg-y\" id=\"image_2047287779\">\n\t\t<a class=\"image-lightbox lightbox-gallery\" title=\"\" href=\"https:\/\/www.bunker-bssd.de\/wp-content\/uploads\/2025\/06\/Explosionsgeschuetzte-Tuer-BD-3-Abmessungen-641x800.png\">\t\t\t\t\t\t<div class=\"img-inner dark\" >\n\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"641\" height=\"800\" src=\"https:\/\/www.bunker-bssd.de\/wp-content\/uploads\/2025\/06\/Explosionsgeschuetzte-Tuer-BD-3-Abmessungen-641x800.png\" class=\"attachment-large size-large\" alt=\"\" srcset=\"https:\/\/www.bunker-bssd.de\/wp-content\/uploads\/2025\/06\/Explosionsgeschuetzte-Tuer-BD-3-Abmessungen-641x800.png 641w, https:\/\/www.bunker-bssd.de\/wp-content\/uploads\/2025\/06\/Explosionsgeschuetzte-Tuer-BD-3-Abmessungen-320x400.png 320w, https:\/\/www.bunker-bssd.de\/wp-content\/uploads\/2025\/06\/Explosionsgeschuetzte-Tuer-BD-3-Abmessungen-768x959.png 768w, https:\/\/www.bunker-bssd.de\/wp-content\/uploads\/2025\/06\/Explosionsgeschuetzte-Tuer-BD-3-Abmessungen-1230x1536.png 1230w, https:\/\/www.bunker-bssd.de\/wp-content\/uploads\/2025\/06\/Explosionsgeschuetzte-Tuer-BD-3-Abmessungen-510x637.png 510w, https:\/\/www.bunker-bssd.de\/wp-content\/uploads\/2025\/06\/Explosionsgeschuetzte-Tuer-BD-3-Abmessungen.png 1320w\" sizes=\"auto, (max-width: 641px) 100vw, 641px\" \/>\t\t\t\t\t\t\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/a>\t\t\n<style>\n#image_2047287779 {\n  width: 100%;\n}\n<\/style>\n\t<\/div>\n\t\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n<\/div>\n<h2>Optional Features<\/h2>\n<p>Additional equipment is available to meet various structural and safety requirements:<\/p>\n<ul>\n<li>Additional Seal Kit<\/li>\n<li>Custom Color Selection<\/li>\n<li>Powder coating according to customer specifications<\/li>\n<\/ul>\n<h2>Applications: Bunkers, shelters, and high-security facilities<\/h2>\n<p>The BD-3 explosion-proof door is a key safety component for sophisticated bunker and shelter designs.
