Our Class 3 security doors can keep you safe from forced entries and burglaries thanks to our innovative designs and high-quality materials.
This specific range is perfect for properties or buildings that need an extra measure of security to protect them from forced entry and/or deliberate attacks – and these doors can even withstand bullets.
Our stylish steel doors are more than just strong - they’re literally impenetrable. Thanks to our broad variety of blast- and bullet-proof security doors, we can protect you from more than just forced entries.
Your home and business security needs often range further than your front door. Thanks to our use of ISEO locks and Euro Cylinders, our light-weight yet strong side-gates keep your property safe by blocking any alleyways or passages.
