Aluminium Deep Tope (Kolgam)

A Shibu engineering first, the world’s first jointless aluminium Deep Tope / Kolgam, pressed from a single circle of metal with no welds and no seams. Where other manufacturers relied on welding to achieve the depth-to-diameter ratio of the Kolgam profile, Shibu engineered the tooling and press capability to deep-draw it in one unbroken piece. The result is a vessel with superior structural integrity, zero contamination risk at weld points, and a lifespan that welded alternatives cannot match.

Widely used across South India for the long-duration boiling of supari (betel nuts) and other bulk commodities, the Kolgam’s tall, cylindrical profile retains heat efficiently over extended cooking cycles.

Ideal for: South Indian bulk food processing, supari and betel nut boiling operations, large-scale institutional storage and cooking, NGO and humanitarian field kitchens.

Available sizes: 30 to 92 | Capacity: 8L to 800L
