Why Calhoun
Calhoun’s clear span interior means there are no poles, pillars, or interference. You have the space to hold your sport or entertainment events while maximizing crowd expectancy.
The natural light of Calhoun’s fabric sports structures permeate the indoor facility, reducing energy costs while maintaining the level of comfort. Skylights and solar panels can easily be added to the building to increase visibility and energy efficiency.
Shorter manufacturing and installation timelines mean facilities can be up and running in a fraction of the time.
Lower upfront investment and reduced operating costs make expansion achievable without overextending budgets.
Customized height preferences allow for the addition of sprinkler systems and emergency lighting. Our fabric sports structures are built to code and approved for use in a variety of recreation applications.
Hot dip galvanized frames and durable HDPE fabric requires less maintenance than traditional indoor or outdoor athletic spaces.
We use fabric with a high strength-to-density ratio to endure even the harshest environments. Our fabric’s unique materials combat the sun’s effects and will not break down under the impact of intense ultraviolet (UV) rays.
High-performance HDPE fabric covers help lower energy consumption and reduce operating costs compared to traditional building systems.
Tell us about your project goals, building requirements, site location, and intended use. Whether you need an indoor tennis court, pickleball court, ice rink, or wedding event venue, our team will help identify the right building solution for your operation and budget.
Once we understand your needs, we review key project details including building dimensions, access requirements, fabric options, doors, ventilation, insulation, and site conditions. We also evaluate local wind, snow, and environmental loads to ensure the structure is designed specifically for your location.
After project approval, our engineering team performs a comprehensive site-specific review using advanced 3D Nonlinear Finite Element Analysis (FEA). Once engineering is complete, the steel framework is fabricated, hot-dip galvanized, and prepared for shipment alongside the fabric building system.
Calhoun offers installation services through experienced crews or can support your preferred contractor. Following installation, our team remains available for inspections, maintenance, repairs, fabric recovering, and relocation services to help maximize the lifespan of your investment.
