Why Shops Choose Copper Bridge

Factory-Backed Supply

You're buying direct from the manufacturer — Dingzhou Jinlong, established 2004. No middlemen, no brand tax. Same wire the big names sell.

U.S. Inventory, Fast Shipping

All inventory sits in our Riverside, CA warehouse. No overseas lead times. Order today, it ships from California.

Full Documentation on File

SDS and TDS ready for every product. COA/COC available on request for applicable products and lots. We keep the paperwork so you don't have to chase it.

THE PROBLEM

Consumables shouldn't be a gamble.

Too many shops deal with mystery wire, inconsistent quality, and suppliers who disappear after the sale. You get a different brand every shipment, no documentation, and no one to call when something doesn't run right.

Copper Bridge exists to fix that. One source, one factory, consistent product, and someone who picks up the phone.
