These are HO scale structural steel 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 elbows allow beams to connect at 90 degrees, making them ideal for:

perimeter framing

floor bays

corners and edge conditions

multi-level steel superstructures

What’s included
25 side-outlet elbow 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 box.

How they’re used
These connectors are designed to be used with Steel City HO scale I-beams to model:

buildings under construction

warehouses, offices, hospitals, apartments, or industrial structures

exposed steel framing before walls, decks, or cladding are added

They are intended for structural framing, 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.

Additional Steel City beams and connectors are available separately in our other listings.

Important notes
HO scale (1:87)

Represents active construction, not a finished building
