Fabrication case study — event stages & backdrops  ·  San Francisco  ·  July 2026

A wall that exists for one day.

Some of our work is meant to last a decade in the sun. This build had the opposite brief: a forty-foot camera-ready wall inside a hotel ballroom, standing by morning, flawless in every photograph, and gone without a trace by midnight. Here is how we build those.

The brief

Ballroom walls aren't built for this.

In July 2026 we were asked to build the stage backdrop for a high-level diplomatic event in a San Francisco hotel — the kind of occasion where every frame of video and every official photograph has the wall in it. A printed banner sags on camera. A pipe-and-drape wall reads exactly like what it is. The brief called for a real wall: rigid, seamless, perfectly matte — in a ballroom where you can't fasten anything to anything.

So we brought the wall with us.

The system

Welded frame. ACM skin. Wallpaper finish.

1

The frame — welded steel, built in our shop

Not rented truss, not clamped pipe: a steel frame welded in our own shop, engineered to stand free on a ballroom floor and hold a wall dead flat. It bolts together in sections, moves in a truck, and assembles in hours.

2

The skin — ACM panels

Aluminum composite panels face the frame, turning steel into a rigid, perfectly flat surface with clean seams. This is the same material we trust on building facades — indoors, it gives an event wall the one thing fabric never can: flatness.

3

The finish — wallpaper-applied graphics

The artwork goes on as wallpaper, applied by hand across the ACM face. No grommets, no wrinkles, no shine — a matte, seamless image that photographs like a painted wall, edge to edge.

Skinned — ACM panels, dead flat

The result

By morning, it had always been there.

Forty feet of seamless graphic, square to the room, matte under broadcast light. It stood for the cameras, did its job behind the podium, and was struck the same night — frame unbolted, panels stacked, ballroom returned as found.

Worth knowing

The frame is reusable — and rentable.

The steel frames are ours, and they work for more than one night: stage backdrops, photo walls, press walls, temporary partitions. We fabricate the graphics, deliver, install, and strike — or rent you the frame system for your own event. Sized to your room, not the other way around.

Planning an event that has to look built, not hung?

Tell us the room, the date, and the artwork — we'll handle the engineering, the fabrication, and the 2 a.m. strike. If the date is close, tell us anyway. Close dates are our specialty.
