About In Demand Trading

Practical experience. Engineering discipline. Structures built to perform.

We combine architectural thinking, technical design and hands-on construction knowledge to deliver tensile structures from concept through to installation.

Our company

A specialist team taking ownership of the complete structure.

In Demand Trading is a Johannesburg-based tensile construction company specialising in the design, engineering, manufacture and installation of membrane structures and architectural shade systems.

Our strength lies in integration. The people developing the geometry understand how the membrane will be patterned, how the steelwork must be fabricated, how the connections will be assembled and how the complete structure will be installed on site.

This coordinated approach helps protect the design intent, control risk and produce a refined final result across commercial, hospitality, educational, retail and residential projects.

Our design office

Where form, structure and construction are resolved together.

Tensile membranes behave differently from conventional roofs. Their strength comes from geometry and pre-tension, making early coordination essential. Our design process considers the full structural system rather than treating the fabric as a later addition.

  • Site assessment and project briefing
  • Concept geometry and coverage studies
  • Membrane form finding and 3D modelling
  • Structural analysis and support design
  • Steelwork, cable and connection detailing
  • Manufacturing and installation information
