Why SignLumi

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.

  • 3,000 m² production floor — we control every step in-house
  • CE & UL certified, with export quality control
  • MeanWell power supplies and Rishang LED modules
  • 2-year warranty on every illuminated sign
FAQ

Questions buyers ask us.

Can you handle large building facades?

Yes — large-format channel and metal letters are a specialty, with structural mounting specs provided for the building contractor.

What materials suit a building facade?

Stainless steel and aluminum for longevity, with back-lit halo or front-lit illumination. We recommend materials based on exposure and the building's architecture.

Do you provide installation drawings?

Yes — full dimensioned drawings, letter spacing and mounting templates, so your local installer places every letter correctly.
