Fire Rated Steel Hinged Doors

Fire rated steel hinged door

Elevate your property’s safety and aesthetics with Harlech’s fire-rated steel hinged doors, perfect for diverse settings from industrial sites to educational institutions. Crafted from corrosion-resistant magnelis steel and boasting a low U-value for enhanced insulation, these doors combine robust security with energy efficiency.

Our fire rated steel hinged doors have an appearance that enable them to be used commercially or industrially, equally at home in industrial units, factories, schools or hospitals. All of our fire-rated steel hinged doors are custom-made using 45mm thick, 1.2mm magnelis steel construction, double skinned with interlocking seams reinforced with integral stiffeners, integrated caps top and bottom, astragal and a Rockwool or Insulfrax core, which offers superior resistance to corrosion when compared with similar Zintec models and offers a verified u-value of 2.1 W/m²K. We can offer either single door or double leaf doors and have a variety of further options available through our additional rigorous third-party testing and assessments by a third party such as global leaders in fire safety, Warrington Fire (Element).

Each leaf is attached to the frame using our stainless-steel dog bolt hinges for greater security as standard and can be furnished with a wide selection of ironmongery including sets for personnel doors (mortice, lock, levers) or escape doors (panic latch), and panel options such as vision panels, vents, etc.

Experience unparalleled safety with our custom steel fire doors, meticulously crafted to provide up to 4 hours of fire resistance.
