SIIOSA Group is a fully integrated metal manufacturing ecosystem — cutting, forming, machining, robotic welding, coatings, and in-house R&D — serving leading global OEMs for over 20 years.
SIIOSA is a Mexican company with over 20 years of experience in metal fabrication and precision manufacturing. Strategically located in Celaya, Guanajuato, we serve leading global OEMs in the construction, industrial, and cleaning equipment industries — delivering integrated metal solutions from cutting to coating.
Engineering, quality, and project management live under one roof, backed by strong financial and operational stability.
A reliable manufacturing company.
A world-class industrial group supporting complex programs from concept to final delivery. Three divisions, one DNA of excellence.
Cutting, forming, machining, welding, finishing, quality control, and dedicated project management for complex industrial components.
Nickel plating, zinc plating, nitriding, e-coat, and powder coating for high-performance, corrosion-resistant applications.
Proprietary technologies, industrial AI applications, integrated equipment solutions, and specialized engineering programs.
We combine advanced processes and in-house capabilities to deliver complete manufacturing solutions — managed end to end by a dedicated project team per customer.
Laser, waterjet, and CNC plasma.
Press brake, tubular forming, and end forming.
3- & 5-axis CNC, lathes with Y-axis, and grinding.
Manual, robotic, and electro welding.
Powder coating, e-coating, and nickel coating.
CMM Zeiss, HandySCAN, X-Ray, and Faro Arm.
Audited quality management to automotive grade.
Plus X-Ray and HandySCAN for full dimensional and structural verification.
Automotive-level launch validation on every program.
Strong EH&S culture with a zero-incident vision.
An Industry 4.0 foundation already running — and a 5.0 strategy where humans and machines multiply each other.
Every process at SIIOSA was developed in-house by Mexican engineers. R+D turns that capability into proprietary software, AI, and simulation.
Computer-vision identification of parts across the plant and finished-goods warehouses — linked to inventory, labeling, supplies, and shipments.
Proprietary scheduling engine: create orders, select an optimization algorithm, and the system generates the optimal plan with real-time floor monitoring.
Predict, analyze, and improve welding performance digitally — long before any physical prototype is produced.
Our finishing and surface-treatment operations now run as a dedicated division — with 3 paint booths and 6 cobots in operation, and a new booth with 2 AI-driven painting robots starting August 2026.
Relocating finishing to a specialized facility frees manufacturing space, raises throughput, and builds the foundation for the Group's next expansions in both manufacturing and coatings.
Full fabrication and assembly lines.
Logistics and distribution center.
New manufacturing & storage facility near MTY airport — optimized for cross-border flow.
New manufacturing plant on a fully industrial site, anchoring the Group's next growth phase.
SIIOSA USA manufacturing facility to serve U.S. programs directly, fully aligned with USMCA supply chains.
10+ year partnerships with continuous, year-over-year growth. We grow when customers grow.
Engineering, quality, and automation integrated under one roof.
Financially stable, with a long-term reinvestment strategy.
Low workforce turnover — key employees with 10+ years at SIIOSA. Your production stays stable.
Investment-trigger capacity model: capacity grows based on customer forecast, with proven scale-up and zero operational disruption.
Industry 4.0 roadmap aligned with customer future requirements, and a strategic footprint across México and the U.S.
Quality, engineering, automation, and scalable capacity — focused on supporting your future programs from concept to final delivery.
