Nowadays, there are many checking doors for pipe wells of various equipment in buildings, which are not often passed, so the upper frame height is generally equal to or lower than the ordinary doors, and there are still thresholds with the same height as the kick line below. The net height of the checking doors need not be limited to about 2 m and 1.5 m.

If the doors and windows contaminated with oil stains and other difficult to clean things, it is best not to use strong acid or strong alkali solution for cleaning, otherwise it will not only easily damage the surface finish of profiles, but also damage the protective film and oxide layer on the surface of hardware and lead to corrosion of hardware.
