The most important things of Steel Door installation is door frame installation. The maximum tolerances for horizontal and vertical lot is +/- 1.5 mm. If exceed from that allowed tolerance, it can't open/close properly cause it will be rub against the floor or the door frame.
The methods of installation that we use are welding system. The tools is welding transformer were need electrical power until 2000-4000 watt. Some welding techniques is used and adapted with opening wall conditions :
  1. Wall with practical column (ring balk on top side) : Welding Techniques : Weld the anchor bar (10-12 mm) on frame side and practical column.
  2. Corewall/Structure : Welding Techniques : set the dyna bolt (min. size 12x75 mm) on the corewall, and then weld the anchor bar (10-12 mm) on frame side and attached dyna bolt.
  3. Gypsum Wall : Welding Techniques : Use C-Channel (min. size 75x35x15x2.3) as hollow frame. Whereas the anchor bar (10-12 mm) was welded on frame to C-Channel.
