Sheet metal fabrication is the backbone of modern manufacturing. Enclosures, brackets, panels, structural frames, and sub-assemblies — virtually every industrial product has sheet metal components within it. Nathan Engineering has positioned itself as a comprehensive sheet metal fabrication parts manufacturer in India, offering the full spectrum of processes from raw sheet to finished, assembled, and surface-treated parts.
The Sheet Metal Fabrication Process
Sheet metal fabrication involves transforming flat metal sheets into three-dimensional components through a sequence of operations:
1. Cutting – Laser cutting, plasma cutting, or punching to produce flat profiles
2. Forming – CNC press brake bending to create angles, flanges, channels, and boxes
3. Joining – Welding (TIG, MIG, spot), riveting, or adhesive bonding
4. Finishing – Powder coating, anodising, electroplating, or painting
5. Assembly – Integration of hardware, fasteners, and sub-components
Nathan Engineering performs all these operations in-house, making it a true one-stop manufacturer of sheet metal fabrication parts in India.
Materials Processed
• Mild Steel (CR and HR) – General structural and enclosure parts
• Galvanised Steel (GI) – Parts requiring corrosion protection
• Stainless Steel (SS304, SS316) – Hygienic and corrosion-resistant applications
• Aluminium (5052, 6061) – Lightweight structural and decorative components
• Copper and Brass – Electrical and decorative applications
CNC Press Brake Bending
Precision bending is a critical skill in sheet metal fabrication. Nathan Engineering’s CNC press brake machines deliver:
• Consistent bend angles (±0.5° tolerance)
• Multi-bend sequences with minimal setup changes
• Back-gauging for precise flange lengths
• Complex bend patterns including V-bends, U-bends, hem folds, and offset bends
As a sheet metal parts manufacturer in India, Nathan Engineering’s bending capability is what transforms flat cut blanks into functional three-dimensional components.
Welding and Assembly
Nathan Engineering’s welding team is trained in:
• TIG Welding – For stainless steel, aluminium, and precision weld joints
• MIG Welding – For carbon steel structural assemblies
• Spot Welding – For high-volume thin gauge assemblies
• Hardware Insertion – PEM fasteners, weld nuts, threaded inserts, clinch studs
Post-weld operations include grinding, blending, and passivation (for stainless) to achieve the required surface condition.
Surface Finishing Options
Nathan Engineering coordinates surface finishing through its partner network:
• Powder Coating – Durable decorative finish in any RAL colour
• Anodising – For aluminium components
• Electroplating (Zinc, Nickel, Chrome) – For corrosion or wear protection
• Passivation – For stainless steel medical and food-grade parts
• Wet Paint – For custom colour matching
