Sheet Metal Fabrication Services for Industrial Projects
Basic Description
Sagiant Piping Industries delivers precision sheet-metal fabrication using CNC fiber laser cutting, turret punching, press-brake bending and certified welding across mild steel, GI, stainless steel, aluminium and CRCA. From prototypes to high-volume production, we cut, form, weld and finish to drawing with full material traceability and ISO 9001 quality control.
Precision Sheet-Metal Fabrication
Our sheet-metal division converts your 2D/3D drawings (DXF, DWG, STEP) into finished components — enclosures, cabinets, chassis, brackets, panels and custom parts — using automated CNC cutting and bending for repeatable accuracy.
