Why SignLumi

A real factory, not a trading company.

When you buy from a trading company, you pay a middleman and wait on someone else's production line. When you buy from SignLumi, you talk directly to the factory that cuts, welds, assembles and wires your signs.

Project Planning

How to scope a mixed signage project

A mixed signage project may include exterior letters, lobby branding, lightboxes, wayfinding, and room or department signs. Planning them as one system improves visual consistency and simplifies procurement.

Map every location

Create a location schedule for the facade, entrance, lobby, corridors, rooms, and back-of-house areas before choosing products.

Create one design system

Agree on typography, color, material, finish, illumination, and fixing details across all sign types.

Coordinate installation

Separate wall-mounted, ceiling-mounted, recessed, and freestanding requirements and confirm who supplies mounting templates.

Plan the delivery sequence

Group signs by building phase or installation zone so the contractor receives complete, clearly labeled packages.

Decision	What to compare	What to send
Exterior identity	Channel letters, metal letters, halo lighting, or lightbox	Facade photo and elevation drawing

FAQ

Questions buyers ask us.

How do I choose a reliable sign manufacturer?

Look for a manufacturer that owns its production line rather than trading on it. SignLumi fabricates in our own 3,000 m² factory, is CE and UL certified, and backs every illuminated sign with a 2-year warranty. Ask for factory photos and a free digital proof before you commit.

Do you manufacture in your own factory?

Yes. We cut, weld, assemble and wire every sign in-house at our Lu'an, Anhui facility. You deal directly with the factory, not a middleman, so you get factory pricing and direct quality control.

What is your minimum order?

One piece. We take single-letter orders and full multi-store chains alike.

Do you ship internationally?

Yes — worldwide. Express shipping is 7–10 days, air freight about 10 days, and sea freight 40–65 days depending on destination.

Can SignLumi supply several sign types for one project?

The product range includes channel letters, metal letters, lightboxes, LED neon, and wayfinding components. Provide a location schedule so the quotation can group compatible materials and finishes.

What should I compare when evaluating sign manufacturers?

Compare factory ownership, material specifications, proofing process, quality checks, packing method, warranty terms, communication, and production lead time. Do not compare headline prices without the same written specifications.
