Our success is built around the belief that things can always be improved. When we started our business, we soon realised that no doorset on the market lived up to our exacting standards, so we designed one that did. 
We made the frame stronger by bolting the corner fixings, we dramatically improved the insulation with a rockwool core. We think most standard steel skins are not secure enough, which is why we made ours even stronger.
Our Defender range is the result.
