Our Process

ClearSpan surpasses other fabric structure companies because we sell directly to our customers — there’s no distributor or middleman in-between. It is our process and our employees that contribute to our success.


Our process starts with you, the customer. Upon your initial inquiry you will speak with one of our ClearSpan Truss Arch specialists. A Truss Arch specialist is a highly qualified team member who will act as your liaison, or account manager, throughout the process of purchasing your engineered fabric structure. Our Truss Arch specialists will listen to your needs and goals for the structure’s application. They will make recommendations based on their experience and knowledge of building codes and regulations. Together you will determine the specifications and customization needed for your ClearSpan Fabric Structure.


If financing is necessary, you will be contacted by one of our ClearSpan financing specialists. Our finance specialists are individuals with extensive credit and finance training. They will gather important background information about your business and your need for a fabric structure, and then thoroughly explain the option that best fits your needs. Instead of just running a report, our financing specialists consider many positive factors before determining the outcome of your credit approval. They will do everything in their power to make one of our finance options work for you.


Whether or not you require financing, once your fabric structure’s specifications have been approved, our engineers take over. The ClearSpan engineering team turns your structure’s customizations and building requirements into a cohesive plan. Using the most updated Computer-Aided Design (CAD) software, our engineers design your fabric structure’s frame. Depending on wind and snow load requirements, along with other building code factors, they determine the needed amount of steel trusses and their required spacing. Our engineers also factor in calculations for customizations such as additional building height. They consistently and effectively create organized building designs for our fabric structures. From these designs the instructions are created for our warehouse team to manufacture your structure.


Steel Trusses

We purchase the highest USA-made, triple-galvanized structural steel tubing for our building frames. Unlike most fabric structure companies, we use round tubing instead of square tubing. Round tubing is far superior to square tubing; it is proven stronger and more flexible at weld points, especially in high wind and snow load areas. In order to provide custom-engineered buildings, our steel workers must individually construct each steel truss in accordance with the design specifications. Following the engineers’ calculations, our workers cut the steel tubing to the correct size using the Computer Numerical Control (CNC) machine and, if needed, bend the steel to the proper angle. Once the steel tubes are cut and bent, they then have to be welded together to create the webbed effect and unmatched strength that ClearSpan’s steel trusses are known for. Certain components of the trusses, such as the anchors, require extreme precision when being welded. For parts such as these, our welders rely on the help of a computer-operated welding machine. Many of our robotic welders are housed in our 100’W x 780’L Hercules Truss Arch manufacturing facility due to its wide open space, durability and abundant natural light.

Fabric Covers

Our fabric covers contribute to the lasting durability of our buildings just as much as our steel trusses. The size you chose for your structure will determine which process we will use for the fabric cover. If the building is less than 100′ wide, we manufacture a one-piece cover for the frame of our Hercules Truss Arch Buildings. This ensures a secure, leak-free fabric cover. To do this, supreme accuracy is required when cutting the fabric. First, members of our cover department cut the fabric into smaller sections in order to ensure the cover will meet the structure’s design specifications. Next, each fabric section is lined up, angled properly and heat sealed into one whole piece. If the structure is over 100′ wide, however, we use individual fabric panels for each section of truss. This is beneficial because less weight and pressure reduces stress to the structure, and fastening the fabric to individual trusses can be done more securely on larger buildings with this method. Once the fabric cover is complete, it is paired with the correct steel trusses and readied for shipping.

Packaging and Shipping

The steel trusses and fabric cover are securely packaged as efficiently as possible. They are properly labeled and arranged to be picked by the courier. The courier is chosen based on which is the most cost effective and reliable for the final destination. If feasible, depending on the delivery location, your Truss Arch specialist will arrange for our installation crew to meet the shipment on site.


One of our installation options is having our construction crew install your Hercules Truss Arch Building. They will arrive with all the necessary tools and equipment needed to erect your fabric structure. Because our crew is experienced and has installed thousands of buildings, they are able to work carefully and quickly when constructing the buildings. If you have any questions, they will be happy to explain the installation process to you. Having our courteous construction crew install your Hercules Truss Arch building provides the perfect ending to your ClearSpan experience.


  1. I would like a athletic multipurpose ClearSpan structure but the land is uneven. Does the company ensure foundation is flat or should I ensure foundation is flat first?

    1. We recommend contracting out the foundation work to ensure it is ready for the arrival of our structures. We are able to assist with foundation needs, but to help keep construction timelines as short as possible, we recommend having foundation work completed prior to the buildings arrival. If you would like to know more about our services or if you have any questions about our product, we recommend contacting a Truss Arch Specialist by phone at 866-643-1010. We would be more than happy to discuss your precise building plans with you and build a personalized quote based on your particular building needs.
