Choosing the right metal fabrication company means finding an operation with the equipment, certifications, and field experience to handle industrial and agricultural work without sending jobs to outside vendors. Dos Rios Inc. has built that capability over more than 35 years of gas field and agricultural contracting, with a full in-house shop, authorized dealer inventory, and a long-tenured crew. Our metal fabrication and welding covers structural components, agricultural assemblies, piping systems, and specialty parts, all produced under one roof. A dependable metal fabrication company runs its own CNC cutting equipment, certified welders, and portable field capability. Metal fabrication and welding performed by one accountable team means tighter tolerances and no gaps between production and installation.

Across gas field and agricultural accounts, our metal fabrication company handles what most clients would otherwise split across three separate vendors. Structural assemblies, piping, and agricultural components are part of the broader metal fabrication that the team delivers to gas field operators and farm owners. Compressor packaging, maintenance, and field repair are covered for clients managing gas compressors who need a team with the inventory to respond fast. Our metal fabrication and welding includes certified pipe work, structural steel, and custom agricultural equipment built to the tolerances that gas field and farm installations demand. Site preparation, trench work, and pipeline construction are available for clients who also need an excavation contractor on the same contract. From irrigation piping to compressor skids, our fabrication services are matched to clients who cannot afford rework or delay. Certified welding, compressor repair, and engine service are all part of our services, delivered by a DOT-qualified crew averaging more than 10 years on the team.

Authorized dealer for many top-notch products.

Family-owned and operated since 1988.

We're not happy unless you're happy. Quality trained - DOT employees ensure safe and efficient work.
What separates our metal fabrication company from a regional shop is the depth behind every job: in-house cutting, certified welding, authorized parts, and field installation under one contract. Every assembly produced through our metal fabrication and welding is built to withstand the continuous demands of gas field and farm operations. Completed structures, piping systems, and compressor skids are documented on our projects, showing the range of what this team builds and installs. The dealer relationships and service history behind this operation are there for clients who want to learn more about us before committing.
