Custom metal signs for San Jose businesses — cast aluminum plaques, brushed stainless letters, brass signs, and dimensional metal lettering. Designed, fabricated, and installed by our team. Backed by Gemini's lifetime warranty on cast aluminum products.
Metal signs are the permanent end of the sign spectrum. Where vinyl and acrylic are the right call for most interior branding, metal is what you reach for when the sign needs to convey institutional permanence — a building entrance, a donor wall, a corporate lobby, an outdoor monument. Cast aluminum, brushed stainless steel, and brass each carry a visual weight that no other material matches.
In San Jose's commercial market, metal signs appear most often as dimensional letters on a building or lobby wall, cast aluminum plaques at building entrances or in memorial applications, stainless steel suite and room identification signs, and custom metal fabrications for corporate identity programs. Most exterior metal signs require a city permit — we handle the full submittal process.
Material choice matters. Cast aluminum is the workhorse — foundry-poured, corrosion-resistant, available in a wide range of finishes, and backed by a lifetime warranty through Gemini Sign Products. Stainless steel reads as contemporary and architectural. Brass carries a classic, formal weight preferred in law firms, medical offices, and institutional settings. We'll recommend the right metal for your application, budget, and environment.

Exterior metal signs — building letters, monument plaques, entrance signs — require a City of San Jose sign permit. We prepare the full submittal package, including engineering drawings, site plans, and landlord approval documentation. You don't navigate the permit office alone.
Cast aluminum, stainless steel, brass, powder-coated steel — each has different properties, costs, and visual results. We'll tell you which metal suits your application, budget, and environment, and show you finish samples before anything goes into production. No guesswork.
Metal sign projects involve more steps than most — design approval, material ordering, fabrication lead time, permit review, and professional installation. We manage the full sequence with one point of contact. Standard cast aluminum plaques ship in 3–4 weeks; custom fabrications run 4–6 weeks.
Metal signage is common across a wide range of commercial and institutional environments in San Jose.
Brushed aluminum and stainless letters for lobby walls, building fascia, and campus entrance signs. Clean, architectural finishes that match the aesthetic of Silicon Valley's office corridors.
Brushed metal room ID signs, ADA-compliant suite markers, and cast aluminum plaques for medical office buildings, hospitals, and multi-specialty clinics throughout the South Bay.
Brass and polished aluminum signs for law firms, financial services offices, and accounting firms. Metal communicates the permanence and professionalism that these industries need at their entrance.
Building entrance plaques, tenant directories in brushed metal, and monument sign faces for commercial property managers across San Jose and Silicon Valley office parks.
Donor recognition walls, building dedication plaques, and memorial signs in cast aluminum for private schools, universities, foundations, and nonprofit organizations.
Cast aluminum building identification, department plaques, and ADA-compliant room markers for government offices, civic buildings, and public institutions in San Jose.
Metal signs are often paired with these complementary sign types for a complete building or office sign program.
Metal sign projects follow a predictable sequence. Here's what to expect.
We discuss your application, environment, and budget. We'll recommend the right metal — cast aluminum, stainless, brass — and show you finish samples. If it's an exterior sign, we pull the applicable zoning requirements for your San Jose address at this stage.
We produce a scaled rendering with exact dimensions, letter heights, finish callouts, and mounting detail. For cast aluminum plaques, we show the layout before the mold is set. You approve the design before anything goes into production.
Production runs 3–6 weeks depending on material and complexity. Cast aluminum plaques are 3–4 weeks standard. Custom fabrications run longer. If a permit is required, we submit concurrent with production to minimize overall timeline.
Metal signs require precise mounting — correct anchor points for the substrate, proper standoff spacing, level alignment. Our installers handle the full job, including any wall patching or touch-up required after mounting hardware is set.
Based in San Jose — we fabricate and install custom metal signs throughout the South Bay.
