Acosta Manufacturing: A Tradition of Quality And Innovation
For more than 50 years, Acosta Sheet Metal Manufacturing (Acosta Mfg.) has built a hard-earned reputation for craftsmanship, reliability, and customer service in the San Francisco and Greater Bay Area.
From humble beginnings in a San Jose garage to supplying high-profile projects like the Tesla Gigafactory, Acosta Mfg. has grown into a respected leader in custom sheet metal fabrication while staying true to its family roots.
The company’s story began in 1972, when founder Sal Acosta was ready to pursue a new adventure in sheet metal work. What started in his garage quickly grew, and by 1996, Acosta Mfg. moved into its current headquarters at 930 Remillard Ct. in San Jose. Over the years, more than a dozen family members have worked for the company, making it a multi-generational family enterprise. Known for his tireless work ethic and “can-do” approach, Sal built a company culture centered on integrity, innovation and customer service.
“At Acosta Mfg., you aren’t just a number,” said Michelle Acosta. “We’re a small shop, so we know our customers and care about them and their projects. We get them their products on time, provide consistent quality and offer recommendations. We’re always looking for ways to improve our services and provide the solutions our customers need, which is why they keep coming back to us.”
SMALL SHOP, BIG IMPACT
A proud Bay Area SMACNA member since 1992, Acosta Mfg.’s team of 35+ employees brings decades of industry leadership and collaboration to every project. With a full range of HVAC duct and fittings, roofing metals and laser cutting, the company is equipped to handle custom-fabricated pieces from concept through completion for both commercial and residential applications.
“Whether you’re a homeowner with plans for a metal countertop or a mechanical contractor with a jobsite needing thousands of feet of commercial-grade ductwork, Acosta Mfg. has the capacity to offer a quick turnaround for small and large jobs,” Michelle said. “A proud union shop, our affiliation with the Sheet Metal Workers’ Local Union 104 provides us with the expertise needed to ensure that all our products meet or consistently exceed the highest quality standards.”
Acosta Mfg.’s reputation for precision and reliability has earned it high-profile work, including supplying more than 500,000 pounds of ductwork to the Tesla Gigafactory in Sparks, Nevada — all while meeting tight deadlines and managing complex out-of-state deliveries. Another standout project was with sustainability-focused tech company 99Bridges, where Acosta Mfg. developed a custom kiosk system enabling shoppers to rent and return reusable bags. This innovation not only showcased Acosta’s versatility but also helped 99Bridges earn recognition as an inaugural U.S. Plastics Pact Reuse Catalyst Partner.
“Serving local mechanical contractors daily, we have proven our value time and time again by putting our clients first and building trust by only promising what we can actually accomplish,” Michelle said.
INNOVATION AT WORK
Always on the cutting edge, Acosta Mfg. was one of the first shops in the area to adopt laser welding technology. This advancement has transformed workflow efficiency, reducing turnaround time to an estimated 25% of traditional TIG welding methods. Acosta is pleased to see this commitment to innovation extending beyond the shop floor with Sheet Metal Workers’ Local 104 and the Bay Area Industry Training Fund (JATC) also investing in the equipment needed to train the next generation of welders in laser welding technology.
LOOKING AHEAD
With over five decades of experience, Acosta Mfg. remains firmly rooted in its values while continuing to embrace new opportunities. Certified as a Minority Business Enterprise (MBE), the company reflects both tradition and progress — family-owned, union-strong and diversity-driven. As they look toward the future, Acosta Mfg. is committed to growing alongside its customers, delivering innovative solutions and trusted craftsmanship that will continue to shape the Bay Area for years to come.
