In order to have the most useful hardware, designers must examine not only appearance but also the size, shape and feel of each element of door hardware and how easy it is to use. Typical design features of a doorknob include no sharp edges or ridges, a shape that can be easily grasped or turned, a textured finish or non-slip coating on knob to improve grip and a shaft which is long enough to fit hand behind knob.
Most doorknobs are made of metal, with the most common type brass. The term brass refers to a group of alloys that contain a combination of varying amounts of copper and zinc. Diydoorfurniture.com is a leading provider of door knobs in UK.
