Plate and Sheet Laser Cutting in Southern California

Plate laser cutting gives clean, smooth edges that are effectively ready to weld. Compared with waterjet or plasma, there is far less cleanup and far less time lost to secondary operations before the part moves to forming.

Holes, alignment keys and custom profiles are cut in the same pass, which cuts assembly time and improves accuracy downstream. For material thicker than the laser envelope we run waterjet — steel to 4 in, aluminum to 8 in and stainless to 3 in.

Two 3 kW fiber lasers with 76 × 150 in beds cut steel, stainless and aluminum. Standard plate stock is 48 × 120 in, stepping up to 60 × 120, 72 × 120 or 96 × 240 in for oversize parts. Mild steel is cut from the grade that suits the thickness: A1008 cold rolled up to 0.125 in, A1011 pickled and oiled over 0.125 to 0.375 in, and A36 hot rolled above that.

Flat parts are nested and quoted by the sheet, and nesting happens only within the file you upload, so send all the parts of one material as a single multibody file: they share stock and setups. Parts uploaded one at a time each get their own sheet and setup and price high. A DXF alone cannot be quoted because it carries no thickness; extrude it to your plate thickness and save it as a part first. Press brake forming runs in the same building, so cut-and-form jobs are quoted as one.

From Fontana we cut plate for fabricators and OEMs across San Bernardino and Riverside counties, Los Angeles and Orange County, and ship across Southern California. ITAR or export-controlled files should not go through the instant quote; email them to sales@calwestmfg.com.
