Providing certified security doors for offices, banks, & other commercial buildings nationwide.

Many commercial facilities require enhanced protection; when valuable equipment and documents are kept on site, a certified security door ensures safety and peace of mind.

Our SR1 and SR2 doors are an excellent choice for offices. Configured to resist forced entry and tested by an independent third party, they’re ideal for deterring trouble. For the more crucial needs of banks, our SR4 doors are engineered to withstand the toughest of tools, including disc grinders, jigsaws, and sledgehammers.

All our security doors can be fully customised with a range of door furniture and come in a variety of colours and finishes. They’re also completely UK manufactured in our own facility.

Emergency doors are another important addition for commercial buildings, to ensure the safety of your workforce and clients. For this need we offer the K1650, our 4-hour fire-rated security door. This features a composite dufaylite honeycomb core to slow down the heating process, and can be customised with a variety of emergency hardware and locking options.
