Door construction

 

  The door is a rugged construction which consists of the frame and leaf. The frame is a weld-fabricated structure of entirely molded steel sections with width of the wall of 2-3 mm. The leaf is a structure of 2 -3mm molded steel sections faced with the steel sheet of 2 mm width. In the leaves with opening for glass unit the structure is forced with additional load-bearing elements and the opening itself is protected with firm still grid. The glass units are produced with the usage of special shockproof film “Solar Guard” manufactured in the USA.
