Special Hinge for Heavy Door - 5 WingsI.B.F.M.
Special hinge for heavy doors and fire doors with ball bearing, to be used in order to open very heavy metal gates, openings or door leaves.
In order to obtain more carrying capacity is possible to use more than a pair of hinges, just paying attention to their vertical spacing. The carrying capacity is highly effected by the dimensions of the door leaf (width and height). During the welding process pay great attention on not deforming or damage both the product and the support profile avoiding overheating. Check the strength of the welding before installing the assembly.
