Sectional Dock Doors

Inkema's dock sectional door is an essential element for any facility, thanks to its very resistant and lightweight structure.

Made of a set of sliding panels with system of bearings. This door has a compensation line ensuring the door is in the desired position, hence not require unnecessary effort to operate it. It can be completely opaque, or it can have small windows in different positions.

Our range of sectional doors enhance the external appearance of any industrial building. Any of our doors provide a resistant and safe enclosure, separating inside from outside, with optimal insulation. Also always complying with safety directives.

  1. Panels: Formed by two sheets of galvanized painting for their external parts and joined by hot injected polyurethane foam to ensure its durability. It is thus obtained an insulation of 1.65 W/m²K.
  2. Tracks: Ready-made with different 2mm. thick galvanized profiles. They hold with total security the rail where the door is slipped through the pre-frame. The tracks are specially designed to take up the minimum possible space and they are presented in different formats (vertical lift, normal lift, high lift, low headroom).
  3. Compensation line: Designed to have a minimum life of 15,000 cycles, and with the necessary springs for their functioning. They are jointed to the rolling drums through an axle. These drums pick up the steel cable that is jointed to the panels and keeps them hung.
  4. Door hardware: Next to the fixing screws, it is galvanized in zinc to ensure its durability.
