Since 1983, built on three promises.
Emperor Supply Inc. and its affiliates have supplied California's builders with electrical, plumbing, HVAC, lighting fixtures and building materials for four decades.
From one Chinatown counter to seven California branches.
Emperor Supply opened on 10th Street in Oakland's Chinatown in 1983 with a simple idea: give the people who build our cities quality products, sincere service and competitive prices.
That idea grew into a family of companies — Emperor Supply, American Ace Supply and American Emperor — with branches in Oakland, San Leandro, San Francisco, Concord, San Jose and Orange. Each location is owned and operated independently, which keeps decisions close to the customers each branch serves.
Today our customers include general contractors, sub-contractors, developers, building owners and facility managers — and plenty of homeowners tackling their own projects. Whoever walks in, we look forward to serving you.

Our three promises
Quality products
Name-brand, code-compliant materials you can install with confidence and stand behind.
Sincere service
Real people at the counter who know the trades — in English, Spanish, Cantonese, Mandarin and Vietnamese.
Competitive prices
Pricing that helps our customers reduce cost and win more bids.
Three names. One commitment.
