Domestic steel door and window manufacturing locksmith factories manufacture a finished product, from the parts from a brand. It depends on the preparedness of the steel window manufacturing company, the production capacity, the quality of the machines, the accuracy and the knowledge and organisation of the team whether this product will really work as well as the engineer dreamt, invented and drew it with the designated or other CAD-software at the time.  

Similarly to aluminium, the value of steel door and window profile system is also given by the quality of the finished product, so the product is very much manufacturer-specific. Due to the significant indoor use of the steel product range, the perfection of welding seams and surfaces, the surface treatment, the quality of the fittings and the installation of the finished product are particularly important.
