Steel Joist Framing
Use this 3 part SimpleSpecs™ template to specify steel joist framing.
The section includes open-web steel joists and joist girders fabricated from steel angle upper and lower flanges with a steel bar or angle diagonal webbing.
What is an open-web steel joist?
Open-web steel joists and joist girders are a type of steel framing system used in the construction of buildings. They are made up of a series of parallel steel members, called chords, that are connected by diagonal web members. The chords are typically fabricated from steel angles that form the upper and lower flanges of the joist or joist girder, while the web members are made from steel bars or angles that connect the chords diagonally.
What is a joist girder?
Open-web steel joists and joist girders are commonly used in commercial, industrial, and institutional construction projects because they offer several advantages over other framing systems. For example, they are lightweight, which makes them easy to handle and install, and they can span long distances without the need for intermediate supports. They are also customizable, which means that they can be designed to meet the specific needs of each project, including the load capacity, deflection criteria, and fire rating.
Why are they important?
- Cost-effective: Open-web steel joists and joist girders are a cost-effective solution for framing buildings. They are lightweight and require less material than other framing systems, which can reduce construction costs.
- Versatile: Open-web steel joists and joist girders can be customized to meet the specific needs of each project. They can be designed to span long distances without intermediate supports, which can result in larger open spaces and more design flexibility.
- Sustainable: Open-web steel joists and joist girders are made from recycled steel, which makes them an environmentally friendly choice. Additionally, they can be recycled at the end of their useful life.
- Fire-resistant: Open-web steel joists and joist girders have a fire-resistant design, which means they can withstand high temperatures without collapsing. This can help prevent the spread of fires and improve the safety of buildings.
- Strong and Durable: Open-web steel joists and joist girders are designed to withstand heavy loads and high winds. They are also durable and can last for many years with minimal maintenance.

Framing that is exposed to weather should be galvanized or protected by a high-performance coating system to minimize rusting.
