The secondary support may be in profiled steel, stainless steel or extruded aluminum sections. Typically, very light weight stainless steel tension rods form a sub-frame that is also see through, to provide a structure matching the properties of glass. This offers the advantage of the sub frame being lost in the view and best in creating space and use of natural light.

This may also take the form of glass fins, which is equally transparent. Steel truss of hollow sections of flat bars are also employed when it ties in with the Architect's design. It is also possible to utilise a combination of the above options to create a high tech look for the glass enclosure.

For specific application of the VisionMax to Atrium or Entrance, please direct inquiry to our Technical Advisory Service. General description, choice of glass and sub-frame, including size and shape can be available for your completion of design work.
