7 Types of Steel Beams for Your Next Commercial Project

Selecting the right steel beam connection is a critical decision in commercial precast concrete construction. Your choice directly impacts the structural integrity and efficiency of the entire project. There are many types of steel beams available, each designed for a specific purpose and load condition.

While Boccella Precast does not manufacture steel beams, we specialize in designing and supplying hollow core precast concrete systems that integrate seamlessly with steel framing. With so many configuration options, it can be a challenge to identify the best connection type for your project. This article guides contractors, engineers, and developers in understanding common steel beam supports and how they work with hollow core slabs to ensure structural success.

The 7 Key Types of Steel Beam Connections for Hollow Core Systems

Each type of steel beam support serves a specific function in supporting and integrating precast hollow core concrete planks. Understanding their unique roles can help you choose the best fit for your structural needs.

1. Typical End Bearing Steel Beam

When it comes to fundamental support, the typical end bearing steel beam is a common choice. In this configuration, hollow core planks rest directly on the top flange of the steel beam, often with a bearing pad and grout to distribute the load. The beam may include bearing plates that spread the weight over a larger surface, preventing stress concentrations and ensuring long-term durability.

2. Typical Side Lap Steel Beam

For open floor designs that require lateral plank connections, you should consider the typical side lap steel beam. This setup supports adjacent precast planks that meet side-by-side over a shared beam. It enables effective load transfer between planks, promoting a more cohesive floor system and reducing deflection across spans.

3. Typical End-End Bearing Steel Beam

In situations where planks from opposite directions meet, such as in long corridors or across linear structural spans, the typical end-end bearing steel beam provides the necessary support. Planks are seated on either side of the beam, and the load is distributed across the length of the member, maintaining balance and minimizing movement.

4. Change of Direction Steel Beam

Complex architectural layouts often require creative structural solutions. This type of connection uses change of direction steel beams to support planks that alter direction—often forming T-intersections or angled transitions. Steel’s flexibility allows for precise alignment and load accommodation without sacrificing design intent.

5. Typical Side-Side Lap Steel Beam

For wide-open floor systems or areas with large slab connections, the typical side-side lap steel beam is an ideal solution. It allows for consistent span capacity and a uniform surface, which is especially beneficial in warehouses, schools, or office buildings.

6. Typical End-End Bearing Upset Steel Beam

Some projects have unique elevation or heavy load-bearing requirements that standard beams cannot meet. In these cases, a typical end-end bearing upset steel beam, where the beam is recessed or modified—allows the hollow core slab to sit lower, offering increased floor depth without raising the overall floor height. Alternate versions, like the upset steel beam 2, may offer varying profiles for more tailored load requirements.

7. Typical End Bearing Elevator Steel Beam

Elevator shafts require beams that offer precise, reinforced support for planks framing the openings. This detail is crucial for maintaining safety and performance in high-traffic vertical systems. The typical end bearing elevator steel beam connection maintains accurate placement and durability in these essential building zones.
