Sliding Folding Doors

  • Over view Heavy-duty door ideal for large openings up to 45m wide and 10m high and able to withstand wind gusts of 150mph. The door consists of 230mm ribbed galvanised sections, hinged vertically by a continuous hinged strip.
  • Top track The top track supports the weight of the door and is made from heavy gauge cold rolled steel strip. It is fixed to the lintel with fabricated mild steel brackets where required, and is galvanised or painted depending on the door size and specification.
  • Pickets Pickets are made from galvanised rolled steel strip and from the main framework for the door on the inside of the building. The top of each picket is supported from the top track with a hardened steel grease sealed multi ball roller. The bottom of each picket runs within the bottom track and gives the door its strength in wind.
  • Leaves 230mm leaves made from cold rolled galvanised steel strip and are ribbed for aesthetic purposes and extra strength. The gauge varies to suit the size of the door.
  • Hinge strip The hinge strip is capped cold rolled galvanised steel channel, which allows the leaves to hinge vertically and move with the picket section when the door is operated.
