If you would like a quote for Crittall/steel style door or partition wall, here at Angell Welding & Fabrications we provide a cost effective alternative as we regularly manufacture and install this style both internally and externally.
My email is info@angellwelding.co.uk if you have any more information/dimensions.
I've attached below a recent project we completed in London
