Global industrial-gas player Nippon Sanso Matheson is planting fresh roots on San Antonio’s West Side, with plans for a new $5.4 million office and production facility at 6430 State Highway 151. The roughly 18,923-square-foot building is set to break ground next Saturday, Aug. 1, with construction expected to run about a year. The project would add another local outpost for the company, which already operates elsewhere in the city.
What the state filing shows
A filing with the Texas Department of Licensing and Regulation pegs the project under registration number TABS2026026046 and describes it as a privately funded, ground-up office and production facility at 6430 State Highway 151, with a planned footprint of about 18,923 square feet. The document lists an Aug. 1 construction start date and a completion date roughly one year later, puts the estimated cost at $5.4 million, and names Matheson Tri‑Gas Inc. as the owner and Melissa Beltran as the project filer, according to the Texas Department of Licensing and Regulation.
Company background
Nippon Sanso Matheson supplies industrial, specialty and medical gases through bulk delivery, cylinders and on-site gas generation systems. Its U.S. website says the company runs more than 300 locations nationwide and employs over 4,500 people. The business is part of Tokyo-based Nippon Sanso Holdings, which describes the group as the world’s fourth-largest supplier of industrial, electronic and medical gases and reports improved consolidated results for the fiscal year that ended March 31, according to Nippon Sanso Matheson and a parent-company filing.
Where it fits locally
The new facility is planned along the SH‑151 corridor on the West Side, a stretch that has been drawing fresh industrial and aerospace investment. As reported by the San Antonio Express‑News, Nippon Sanso Matheson already runs a site on the East Side at 3566 N. Pan Am Expressway. The newspaper noted it is still unclear whether operations might shift to the new address and that the company did not respond to a request for comment before publication.
Next steps and questions
The TDLR registration states that the project is privately funded and that no tenant has been assigned yet, leaving open questions about staffing levels, the specific mix of operations and any traffic or safety impacts. The filing also lists a registered accessibility specialist and reminds owners about inspection requirements under state code, according to the Texas Department of Licensing and Regulation. Local officials, neighbors and potential suppliers are likely to watch permits and early site work closely as the company moves toward breaking ground.
