The Metalworking Legacy of Southeast Los Angeles County
Downey's aerospace history created a powerful metalworking ecosystem that still thrives in surrounding cities. Paramount, South Gate, Gardena, and Santa Fe Springs host forging plants, machine shops, heat treaters, and fabricators that supply aircraft engines, rockets, satellites, and industrial equipment. These companies employ skilled machinists, welders, and engineers, many of whom live in Downey.
Metalworks companies range from global aerospace suppliers to neighborhood fabrication shops that build custom gates, railings, and structural steel. This guide highlights ten metalworks companies that represent the depth and diversity of the industry serving Downey.
What to Consider When Hiring a Metalworks Company
Choosing a metalworks partner depends on the project. Aerospace and defense customers require certifications such as AS9100 and Nadcap accreditation for special processes. Construction projects demand certified welders and structural steel expertise. For any project, evaluate equipment capabilities, material expertise, quality control procedures, and capacity to meet deadlines.

Apprenticeships and on-the-job training allow new workers to build valuable skills while earning income, and certifications can open doors to aerospace and defense positions.
Frequently Asked Questions
What is the difference between forging and machining?
Forging shapes metal by applying intense pressure, often while it is heated, which improves strength and grain structure. Machining removes material with cutting tools to achieve precise final dimensions. Many aerospace parts are first forged and then machined.
How do I find a fabricator for a residential project?
For gates, railings, and structural steel at home, look for licensed contractors with welding certifications and experience with City of Downey permits. Ask to see past work and confirm the finish will resist corrosion.
Which metals are most common in aerospace?
Aluminum alloys, titanium, stainless steel, and nickel-based superalloys are widely used. Each offers a different balance of weight, strength, heat resistance, and cost depending on the component.
