Inverted Cone Tensile Structure

Inverted cone tensile structures are unique, fabric-covered buildings that provide excellent and stunning structural integrity and aesthetic appeal. It collects 100% roof water and can divert to rainwater harvesting sumps. Inverted cone tensile structures are large, conical-shaped structures that can be used for patios, walkways, and event spaces. They are made from tensile fabric that is durable, weather resistant, and elastic. The material used can affect the structure's properties, for example, ETFE film gives the structure UV resistance and greenhouse properties, while fiberglass coated Teflon makes it more resilient to weather. 

Here are some of the features of inverted cone tensile structures: 

• Aesthetic look: The conical shape of the structure creates an eye-catching look. 
• Easy to install and maintain: These structures are easy to install and require low maintenance. 
• Durable: Inverted cone tensile structures are extremely durable. 
• Allow natural light to filter through: These structures allow natural light to filter through, creating a visually striking canopy. 
• Can be used in a variety of settings: These structures are ideal for patios, walkways, and large event spaces.
