Sree Durga Fabrications runs the same shop floor, the same crew and the same equipment that has delivered 300+ fabrication projects since 2019 — formerly under Rainbow Engineering & Manufacturing, now also operating independently, with projects continuing between the two.
Sree Durga Fabrications is a full-service mechanical fabrication company covering everything from raw sheet metal to a finished, powder-coated, ready-to-ship assembly. We were built by the same people who founded Rainbow Engineering & Manufacturing in 2019, and we run the same shop, the same machines and the same standards.
Today we operate as an independent fabrication company under the Sree Durga name, while continuing to deliver and associate work together with Rainbow — every project either company has completed since 2019 is part of one shared track record.
Whether it's a single prototype for a lab or a production batch of enclosures for a factory floor, the same motto applies: quality and reliability, from raw material to finished part.
Six core services cover the full journey from flat sheet to finished, coated component — with design and machine-development support built in.
Cutting, punching, forming and assembly of enclosures, chassis, brackets and structural parts to spec.
Certified welders across four processes — precision TIG, fast MIG, heavy-duty ARC and micro laser welding.
Tight-tolerance laser cutting paired with modern press brakes for accurate, repeatable multi-bend forming.
Full prep-to-finish surface treatment, plus spray painting for custom colours and specialised finishes.
CVM 800 and Haas milling centres for prototypes through production, plus purpose-built machine development.
3D CAD import (STEP / IGES / STL), design-for-manufacture feedback and full project management.
The same machines that have shipped 300+ projects — sized, specified and maintained for both prototype work and production runs.
Large-capacity setup for oversized parts, uniform cure and a wide range of colours and textures.
Rust and scale removal, old coating strip-off and surface profiling ahead of finishing.
Versatile centre for complex geometries, prototypes and small batches with tight tolerances.
Built for demanding production runs with consistent, repeatable output quality.
Certified welders covering every joint type, from precision seams to heavy structural welds.
Accurate forming for consistent angles and complex multi-bend configurations.
Precision components for pharma manufacturing equipment.
Enclosures, chassis and custom parts for electronic systems.
Fabricated components and assemblies for automotive applications.
Custom machinery frames, guards and application-specific solutions.
Finishing support with precision-fabricated tooling.
A track record built jointly since 2019 — delivered either directly by Sree Durga Fabrications or as a / associate partner alongside Rainbow Engineering & Manufacturing.
Industrial automation — servo drive enclosures and precision components.
Surface finishing — custom tooling and fabrication support.
Nuclear instrumentation — precision enclosures and assemblies.
Quantum technology — precision machined components.
