About
Sign King, Inc.
A Guam sign and building-trade contractor in Harmon Industrial Park.
Welcome to Sign King, Inc.. Over the years we have garnered the trust of island customers because the work is built with quality materials and current lighting and fabrication methods. That sentence is the same promise the company published on signkingguam.com in 2020 — and it still holds.
The shop fabricates custom signage: LED channel letters, aluminum lighted boxes, and interior identity. It also contracts electrical, HVAC, sheet metal, welding, and painting. Federal and GovGuam work is part of the book — NAVFAC, GSA, Andersen AFB, and DZSP / Amentum among them.
We make the best looking signs on the island. Call (671) 646-1166 if you have a drawing, a storefront, or a facility spec.
