Corporate Interior Signage

Transform your physical space. We forge premium interior signage systems that reflect the caliber of the work happening inside your walls.

Corporate Interior Signage

The exterior sign brings them into the building; the interior signage tells them what kind of company they just walked into. SignForge builds interior signage that feels permanent, intentional, and high-end. From edge-lit acrylic lobby logos to brushed-steel boardroom graphics and ADA-compliant office plaques, we fabricate complete interior packages that unify your brand's physical environment.

Fabrication

How we build it.

Five disciplines under one roof — engineered metalwork, digital precision, and hand craftsmanship.

  1. Welder fabricating a steel sign frame

    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.

  2. MultiCam CNC router carving wooden sign panels

    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.

  3. Fiber laser cutting precision metal sign components

    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.

  4. Large-format Roland printer producing a vinyl banner

    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.

  5. Craftsman hand-finishing dimensional letters

    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.

Fabricator measuring channel letter depth
Do you know the ADA compliance laws for interior signs?
Yes. We strictly adhere to California Building Code and federal ADA guidelines regarding braille placement, tactile lettering depth, and mounting heights to give you the best possible outcome on your final inspections.
Can you install signs on a tile or stone lobby wall?
Yes. We use diamond-tipped drills to carefully install pin-mounted letters into marble, granite, or tile walls without cracking the stone.
We are moving offices. Can you move our lobby sign?
Yes, we offer removal and re-installation services. If the sign was mounted with certain permanent adhesives, we may need to fabricate a new backer panel for the new location.
