Steel doors -RC3- class provide high parameters of protection against burglary while maintaining the advantages of an ultra-light construction and a wide range of patterns and colours.
are a good example that high safety factor does not mean sacrificing aesthetic characteristics and good design. A wide range of decorative ribbing, and a large variety of colours of anti-theft -RC3- doors is especially important when used in public buildings and housing. Extremely important for the proper classification of the doors is the multi-faceted locking system in the form of anti-theft locks and pins protecting the door against forcing open and the construction of the door leaf provides its required stiffness and resistance to deformation. Steel doors designed to meet the requirements of the PN-EN 1627:2012 standard in RC3 class are subjected to many tests in laboratory conditions; i.a. manual tests, using tools from A3 group and dynamic tests. Positive tests, qualifying the door to RC3 class guarantee their users high level of safety and comfort of operation.
