Drawing-based fabrication

Custom Fabricated Components Manufacturer in India

Rajog manufactures custom fabricated components for industrial, OEM and engineering applications based on customer drawings, dimensions and technical specifications — combining heavy fabrication, plate rolling, forming, welding and machining capabilities.

Beyond off-the-shelf parts

Custom fabricated components for industrial applications.

Industrial equipment often requires components that cannot be sourced as standard off-the-shelf parts. Rajog manufactures custom fabricated components according to project-specific dimensions, material requirements and engineering specifications.

Plate rolling

Plate rolling for fabricated components.

Certain fabricated components require curved or cylindrical sections before welding and assembly. Rajog's plate rolling capability supports the manufacturing of rolled components, cylindrical sections and equipment shells.

Machining support

Machining support for fabricated components.

Some fabricated components require additional machining after fabrication. Rajog combines fabrication with CNC and heavy machining capabilities where the component design requires both processes — reducing the need to coordinate multiple manufacturing suppliers for suitable projects.
