DIY – A Step by Step Guide to Creating a Reduced-Scale Tensile Membrane Structure with Spandex and Steel Wire

Unveiling the Secrets: A Step-by-Step Guide to Creating a Reduced-Scale Tensile Membrane Structure with Spandex and Steel Wire

The world of tensile membrane structures is captivating, with its awe-inspiring forms and innovative use of materials. But have you ever wondered how to explore these concepts on a smaller scale? This guide delves into creating a reduced-scale model using readily available materials – a fun and rewarding exercise for students, enthusiasts, or design professionals.


  • Spandex hose stocking (cut into a large piece)
  • Steel wire (thin gauge, for easy manipulation)
  • Wire cutters
  • Pliers
  • Scissors
  • Modeling clay or hot glue (for attaching elements)
  • Optional: Spray paint (for a polished finish)

Step 1: Envision and Sketch

Before diving in, take a moment to envision your design. Sketch a basic concept of your desired tensile membrane structure. Will it be a simple cone, a sinuous curve, or a more complex geometric shape? This initial sketch will serve as a roadmap for the construction phase.

Step 2: The Spandex Canvas

a) Shaping the Fabric: Carefully cut a large piece of the spandex hose stocking. The fabric’s elasticity allows for flexibility in shaping. You can drape it over a pre-made mold (e.g., balloon, bowl) or manipulate it by hand to achieve your desired form.

b) Securing the Edges: Once you’re happy with the basic shape, use scissors to trim any excess fabric. To prevent fraying, consider applying a thin bead of hot glue or fabric sealant along the edges.

Step 3: Crafting the Steel Skeleton

a) Bending the Steel Wire: Using the wire cutters, cut multiple pieces of steel wire to appropriate lengths based on your sketch. With pliers, carefully bend the wire segments to create the supporting structure for your tensile membrane. The beauty of this exercise lies in experimentation – don’t be afraid to bend and reshape the wire until you achieve the desired form.

b) Connecting the Frame: Once you have your individual wire segments, connect them using small loops or bends. The connections should be secure but also allow for some adjustability to fine-tune the overall structure.

Step 4: Marriage of Fabric and Frame

a) Attaching the Spandex: Here comes the delicate part. Gently stretch the spandex fabric over the steel wire frame. You can use modeling clay or hot glue to secure the fabric to the wire at strategic points, ensuring the tension is evenly distributed.

b) Achieving the Ideal Tension: The key to a successful tensile membrane structure lies in maintaining balanced tension in the fabric. As you attach the spandex, be mindful of pulling it taut but not excessively. A slightly loose fabric can be tightened later with careful adjustments.

Step 5: Refinement and Presentation (Optional)

  • Once the basic structure is complete, take a step back and assess your creation. Are there any adjustments needed to the tension or the form? Make any micro-corrections to achieve the desired aesthetic.
  • For a professional presentation, consider spray painting the steel wire frame a uniform color or WHITE colour stocking. This will enhance the visual impact and create a more polished final product.

Step 6: Embrace the Journey!

Building a reduced-scale tensile membrane structure is an engaging exercise that allows you to explore the principles of form, tension, and materiality. Don’t be discouraged by minor imperfections – the process of experimentation and refinement is part of the learning experience.

Professional Pointers:

  • Material Selection: While spandex offers a good balance of affordability and stretch, consider exploring other fabrics like sheer curtains or stockings for different effects.
  • Complexity vs. Simplicity: For beginners, start with a simple geometric shape like a cone or a pyramid. As you gain confidence, experiment with more complex forms.
  • The Power of Observation: Draw inspiration from real-world tensile membrane structures. Observe how the fabric interacts with the supporting elements and how tension is distributed.
