Door frames are made of stainless steel and are fixed between the vertical sectional braces. The door system is usually made of stainless steel, painted with powder anti-bacterial varnish in the colour shade in accordance with panel facing and is fixed in the door frame.
The door system is either one-leaf or dipteral, rotary or sliding, solid or glassed-in with an electronic blind, with or without the protection against X-rays., with special glass with the content of Pb and a metal sheet with Pb. The door systems can be electronically operated using buttons or elbow switches or mechanically.
