Claim the skyline. We engineer, build, and install massive, illuminated architectural letters that dominate the city from hundreds of feet in the air.
High-Rise Building Signs
Putting a sign on top of a 40-story building is not a design project — it's a structural engineering undertaking that demands a different class of contractor. High-rise signs endure brutal wind loads, coastal salt air, and extreme temperature swings year-round. SignForge is built for altitude. We work closely with structural engineers to design large-scale aluminum frames and high-output LED arrays that are lightweight, intensely bright, and structurally engineered to outlast the building's facade. From boom crane lifts to swing-stage rigging and sectional freight-elevator assembly, our crews execute flawlessly at any elevation.
Fabrication
How we build it.
Five disciplines under one roof — engineered metalwork, digital precision, and hand craftsmanship.
01
Structural Metal Fabrication
Heavy-gauge steel and aluminum are cut, welded, and reinforced in-house to engineered specs. Every frame is built to withstand decades of wind load, seismic movement, and coastal weather.
02
Precision CNC Machining
Automated multi-axis CNC routers carve intricate 3D profiles from thick wood, PVC, and composite stock with sub-millimeter accuracy. The result is repeatable, dimensional detail that hand tooling can't match.
03
Advanced Laser Cutting
High-powered lasers slice acrylic and plastic with flame-polished, ready-to-finish edges, and cut thin metals to tight tolerances. Every letter, logo, and inlay assembles cleanly the first time.
04
Large-Format Digital Printing
Commercial-grade flatbed and roll printers produce vivid, UV-stable graphics on substrates up to monument scale. Inks and laminates are rated for years of outdoor exposure without fading or peeling.
05
Artisan Hand-Finishing
Master craftsmen complete every piece by hand — custom color matching, fine detail painting, and meticulous finishing. It's the final layer that separates a manufactured sign from a signature one.

FAQ
Common questions.
- How do you maintain a sign that is 40 stories up?
- We engineer our high-rise signs for low-maintenance longevity, using premium LEDs and power supplies housed in easy-to-access remote cabinets inside the building whenever possible.
- Do you handle the engineering permits?
- Yes. High-rise signage requires rigorous structural engineering stamps and specialized city permitting. We coordinate the licensed engineering work and manage the entire permitting process end-to-end.
- How do the signs get up there?
- Depending on the building, we use boom cranes, swing-stage rigging, or disassemble the sign into sections for freight elevator transport and rooftop assembly.
