Bar joists — also called open web steel joists — are lightweight, pre-engineered components built with a web of steel angles between parallel chords. They're widely used in warehouses, schools, shopping centers, and offices, and their open design makes it easy to run mechanical, electrical, and plumbing systems through them.

The Value of USA-Made Bar Joists

Domestically fabricated joists mean tighter quality control and stricter code compliance — no hidden flaws, no guesswork. Our bar joists offer:



• Efficient load distribution for uniform and concentrated loads
• Lightweight construction that reduces material and handling
• Cost-effectiveness through optimized design
• Customization in size and configuration

Choosing the Right Size and Configuration

The right joist depends on your project's specific demands:

• Floor vs. roof: Floor joists need more depth/tighter spacing for heavier loads; roof joists must still handle wind and snow loads.
• Key selection factors: span length, load capacity, joist depth/spacing, and any custom configuration needs.
• Engineering fit: Joists must align precisely with architectural/engineering specs to avoid costly changes and ensure the final structure performs as designed.

Why Quality Can’t Be Compromised

Low-quality joists can bend, warp, or fail under stress — leading to delays, replacements, or safety hazards. Precision engineering (accurate welds, consistent measurements) is what separates reliable joists from risky ones, saving time, money, and reducing liability.
