Steel City HO Scale Steel I-Beam Side-Outlet Tee Connectors (25 Pieces)

These are HO scale structural steel tee connectors designed for building in-progress steel superstructures — not finished buildings. They are part of the Steel City structural steel system and are sold the same way real construction materials are sold: as individual components.

Side-outlet tees allow two beams to pass straight through, with a third beam branching off at 90 degrees. They are commonly used where interior framing meets cross-members and where floors or bays tie into a main structural line.

What’s included
25 side-outlet tee connectors

HO scale (1:87)

Engineered to fit 1′-0″ × 1′-0″ HO scale steel I-beams

Authentic job-site appearance
All connectors are molded in a red steel primer color, matching the protective primer used on real structural steel when it arrives on a job site. This gives your model the correct under-construction look, right out of the package.

How they’re used
Side-outlet tees are ideal for:

interior framing and bay layout

floor and roof structure connections

multi-level steel superstructures

warehouses, hospitals, offices, apartments, and industrial buildings under construction

These are structural connectors, not decorative detail parts.

Modular & expandable
This is not a kit and not a fixed design. Buy only the components you need, add more as your project grows, and build exactly what your layout calls for — just like real construction.

Side-outlet tees are fully compatible with other Steel City beams and connectors. Additional components are available separately in our other listings.

Important notes
HO scale (1:87)

Represents active construction, not a finished building
