Why choose Strongdor?

Decide on Strongdor and you will join a growing number of building, construction and facilities management professionals who insist on quality and service without compromise. Perfect for new build, renovation or maintenance, our steel doors are becoming the first choice time after time, and here’s why:

Accreditation and quality

We manufacture steel doors in the UK to very precise standards. From design to dispatch, we check them at every stage of the process for build quality and finish.

All our doors are custom made, so they can be configured to comply with most building standards (including the prestigious Secured by Design mark). Most commonly rated and certified for fire, security, acoustic and thermal performance, our ranges also include specialist doors with blast and bullet proof properties.

Value for money

Let’s be honest, you can find cheaper steel doors on the market, but ask yourself why?

Are they made from quality steel? Is the leaf Dutch folded for superb stability and resilience? Do they come powder coated and with a full fixing kit? Do they save time and money on site with adjust-to-fit frames? Will they need to replaced in 12 months time?

Sometimes what looks like a bargain can actually cost more in the long run.

Superb customer service

Talk to the expert sales team. Most have spent time in the industry, fitting doors and hold key steel door insights. They save you time and money in ordering the right door.

In production, we source the best steel, expertly designing, fabricating and building excellent steel doors. Keeping you up to date with delivery schedule and advising on any special site requirements.

When the door is fitted, we offer after sales care that is second to none. We won’t leave you in the lurch.
