Complete welding and fabrication capabilities for precision metal parts, chassis, assemblies, and production-ready components.
Joining fabricated metal components for structural, cosmetic, and sealed applications, including weldments used in enclosures, assemblies, rack chassis, and industrial equipment.
Prototype, short-run, and production fabrication for sheet and plate projects built to customer drawings, with welding integrated into the larger manufacturing workflow.
Custom-fabricated sheet and plate components produced to exact customer specifications for precision, commercial, and industrial applications requiring dependable fit and repeatability.
Press brake forming creates angles, channels, boxes, enclosures, and complex geometries before welding, helping components align accurately during final fabrication.
Mechanical assembly support includes hardware insertion, riveting, multi-part weldments, chassis systems, and finished units that reduce downstream production work for customers.
Deburring, graining, and coordinated coated or plated finishes help welded parts leave the shop cleaner, safer, and better prepared for final use.

We begin by reviewing your drawings, materials, quantities, tolerances, and application requirements. For Livermore and Bay Area manufacturers, this early review helps align weld design, fabrication steps, and delivery expectations before production begins.

Ron Nunes Enterprises was founded in 1969 after Ron Nunes recognized a need for manufacturing services that could support consumers and businesses across many applications. From its Livermore headquarters on Las Positas Road, the company has grown into a full-service precision metal fabrication manufacturer serving commercial, industrial, public, and private sector markets. Over more than 55 years, the team has continued adapting to the needs of Bay Area technology, transportation, communications, defense, and research customers. Today, Ron Nunes Enterprises remains committed to manufacturing excellence, helping customers move from product development through reliable welded parts, mechanical assemblies, rack mount chassis systems, and production fabrication.
Welding cost depends on the metal type, material thickness, joint design, required finish, part quantity, tolerances, and whether prep, forming, assembly, or finishing is needed. Ron Nunes Enterprises quotes projects based on customer drawings and specifications, helping identify cost-effective manufacturing options before production begins.
