Techarsh manufactures precision-engineered corrugated transformer tanks through a fully integrated in-house production setup. From manufacturing corrugated fins to high-end laser cutting, CNC bending, welding, fabrication and painting, every critical process is performed under one roof. This ensures dimensional accuracy, superior surface finish, consistent quality and complete control over delivery schedules.
► Corrugated tank wall and complete tank assemblies
► Top frame, bottom plate and fabricated structural elements
► Lifting lugs, mounting arrangements and supports
► Nozzles, openings, brackets and connection features
► Custom accessories and bought-out-item interfaces as per drawing
► Surface-prepared and painted assemblies to approved coating specification
Every tank requirement begins with the approved drawing and bill of materials. Material preparation, corrugation, fabrication, welding sequence, dimensional control, integrity testing and coating are planned around the specific design. Critical interfaces, mounting points and accessory locations are checked before release so the tank reaches the customer ready for the next assembly stage.
