A pole barn truss is a special building truss that is designed specifically for setting onto the post that is set for the wall structure.

Like any construction project, it depends on several things: spacing, load requirements, steel pricing, etc. As of early 2023, approximate pricing for a standard 12' center 40 ft pole barn truss is around $500.

It depends on the engineer's specs and drawings, but it's typically from 8-12 feet.

It depends on the application and the market costs of wood vs metal or steel. Sometimes they are cheaper and at times the pricing is similar.

We have a variety of pre-engineered drawings on hand for 40 ft pole barns that we can build a wide variety of trusses for quickly. Any customizations that affect structural components are sent for reengineering.

At Buffalo River Truss, we understand the importance of high-quality trusses in construction projects, which is why we prioritize delivering durable and reliable products to our clients.

Metal pole barn trusses are engineered structures that are designed to support the roof of a building. They are made of high-strength steel, which makes them capable of handling heavy loads and withstanding extreme weather conditions. At a length of 40 feet, these trusses are ideal for larger buildings, providing a strong and stable foundation for the roof.

According to industry statistics, steel is one of the most popular materials used for trusses in modern construction. In fact, it is estimated that more than 50% of all trusses manufactured in the United States are made of steel. This is due to the material's high strength-to-weight ratio, which allows for efficient and cost-effective construction.

At Buffalo River Truss, we take pride in providing our clients with high-quality metal pole barn trusses that meet their unique needs. We use advanced technology and equipment to manufacture our trusses, ensuring that each one is made to precise specifications and of the highest quality.

According to the Metal Building Manufacturers Association (MBMA), "More than 50% of low-rise nonresidential buildings in the United States are constructed with metal building systems." Additionally, one American Institute of Steel Construction (AISC) guide notes that "Steel trusses offer durability and fast assembly for roof construction projects, allowing for faster building completion times."

Forty-foot metal pole barn trusses are an essential component of many construction projects, providing the necessary support for roofs and ensuring the overall stability of a building. At Buffalo River Truss, it is our goal to make building large structures as simple and safe as possible. Our 40ft pole barn trusses stem from that commitment.
