S 40

S.40 is a system of folding glazed doors with a robust structure, composed of modular elements made from aluminium profile bars. Exclusive concealed hinges and high design standards offer attractive and original visual results, and ensure excellent protection against weather conditions.

All components are produced to exclusive TENDER Srl designs with accurately selected materials that are fully tested to guarantee only the best functionality, reliability and duration.

  • Fields of application:
    Verandas, balconies, bars, solar greenhouses, restaurants, hotels, shopping malls, etc.
  • Dimensions:
    Made-to-measure door panels up to 900 mm in width and 3000 mm in height. Closures of unlimited length can be constructed by composing groups of door panels running on tracks, with special joints and seals at their meeting points.
  • Sliding:
    Door panels run on two tracks. Door panels are usually suspended from the upper track with ball-bearing runners covered with synthetic material, and the lower panel edge has rollers in synthetic material that run in an aluminium track on the floor, or in a sunken stainless steel track. If the upper structure is too weak to support the weight of the door panels, they can slide with runners on the lower track.
  • Closure:
    Easy, quick and silent. Door panels can be folded together on the left or right only, or on both sides for larger verandas. The closed panels occupy a space of about 9% of their total opened length.
  • Adjustments:
    The end joints and the upper and lower tracks in aluminium are adjustable.
  • Glazing:
    Plain glass, safety glass, insulated glass, panels, etc, with a thickness up to 24 mm.
  • Important features:
    Hinges completely concealed inside profile bars enhance the visual appearance of S.40 glazed folding doors, giving extra protection against intruders and ensuring excellent resistance against weather conditions.

Removable hinge pins for easy cleaning of external surfaces.
