ASTM A992 & A913-65 Steel Beam
Finding a steel beam supplier with the sizes, grades, and lead times a project actually needs can slow a job down before it starts. Undersized sections, thin grade selection, and long backorders push timelines and budgets in the wrong direction. Triple-S Steel® solves that with an expansive steel beam inventory built for fabricators and manufacturers who cannot afford to wait. Our wide-flange steel beams are available starting at 20 feet, with many length options to give you the flexibility to match your project dimensions.
Length Options
We stock steel beams starting at 20 feet and offer a wide range of available lengths to help match your project specifications. Need a specific size or length? Our team can help confirm availability and sourcing options.
Grade Availability
Our steel beam are primarily available in A992 grade. This grade is known for its high strength and durability, making it ideal for construction projects that demand reliable and robust materials. We also offer A913-65 grade beam, which are known for their excellent strength-to-weight ratio and increased resistance to atmospheric corrosion.
Jumbo Beams
Jumbo beams are heavy structural beams that are larger than standard wide flange sections and typically found in large-scale construction and heavy infrastructure. Triple-S Steel® carries a range of jumbo beam grades and sizes to match demanding project specs.
Wide Flange Beam vs. Steel I Beam: Know the Difference
The terms wide-flange beam and steel I-beam are used interchangeably on the jobsite, but they describe two different shapes. A true I-beam, sometimes called an S-shape, has a narrower flange with a taper on the inner surface. A wide-flange beam, or W-shape, has wider, parallel flanges that spread the load over a broader area, which is why most modern structural specifications call for a W-shape even when the spec sheet says I-beam. Confirming which shape a design actually requires before placing an order protects load capacity and connection details down the line.
Steel beams are readily available in unique lengths starting at 25' and can be rolled to special increments depending on the project size. If a project calls for a true S-shaped steel I-beam, our extended network of metal distribution brands can help source the right profile.
Structural Steel Beam Applications
Structural steel beams carry load across some of the most demanding builds in construction and manufacturing, and choosing the right metal beam affects safety margins and long-term maintenance costs alike. Triple-S Steel® supplies the grades and sizes structural beams need for the following applications:
Commercial and Industrial Construction
Wide flange beams and jumbo beam sections form the primary framework in warehouses, manufacturing plants, and multi-story commercial buildings, where high load capacity and predictable performance are non-negotiable.
Infrastructure and Heavy Industry
Structural steel beams support bridges, platforms, and heavy equipment foundations that need to perform under sustained loads and demanding jobsite conditions. A913-65 grade beams provide increased strength for high-load applications while offering strong weldability, helping fabricators and contractors improve connection efficiency and support structural performance.
Manufacturing and Equipment Support
Junior beam and lighter wide flange sections support mezzanines, equipment platforms, and interior framing where a full jumbo beam is not necessary but structural integrity still matters. These sections often pair with channel and angle for complete framing systems.
Value-Added Processing Services
Our value-added services include cutting, sawing, plasma and drilling, so steel beam arrives ready to use with less prep on the jobsite. While we don't galvanize beam in-house, we coordinate with trusted partners to add that service when a project calls for it.

Frequently Asked Questions
What's the difference between a wide flange beam and a steel I beam?
A steel I beam, or S-shape, has narrower, tapered flanges. A wide flange beam, or W-shape, has wider, parallel flanges that distribute load across a broader surface. Most modern structural specifications call for wide flange beams, but our team can help source true S-shapes when a design requires one.
What grades of steel beam do you carry?
We stock ASTM A992 as our primary grade, along with A913-65 for projects that need extra strength-to-weight performance and weldability.
What length options are available?
Steel beams are readily available in unique lengths starting at 25' and can be rolled to special increments depending on the project size.
Do you provide processing services for steel beam orders?
Yes. We offer cutting, sawing, plasma, and drilling to deliver beam that's ready for the jobsite. We don't galvanize in-house, but we coordinate with trusted partners when a project calls for it.
Which Triple-S locations stock steel beam?
Beam availability varies by branch and is supported by our broader network of distribution brands. Contact us with a location and project specs and we will route the order through the closest stocking source.
