Welded Silos for Bulk Material Storage


Indpro’s Welded Silos are designed to store bulk solids safely, efficiently, and hygienically across a wide range of industries. Engineered with a deep understanding of bulk material flow behavior, our silos ensure smooth storage, controlled discharge, and seamless integration with downstream processes such as pneumatic conveying, dosing, and packaging.

vailable in carbon steel, stainless steel, or special alloys, Indpro’s welded silos are custom-built to match material characteristics, capacity requirements, site conditions and plant layouts-making them a dependable choice for modern process plants.

Why Choose a Welded Silo?

While bolted silos are ideal for large-volume, infrastructure-oriented storage, welded silos are the preferred choice for process-critical industrial applications where material flow reliability, hygiene, and system integration are essential.

Indpro’s Welded Silos are engineered not just for storage-but to perform as an active part of your bulk material handling and pneumatic conveying system.

Welded Silos FAQ's

Bolted silos are assembled from modular panels at site, while welded silos are fully welded one-piece units. Bolted silos offer convenient transportation and easier expansion.

Flow is ensured through optimized hopper design and optional flow-assisting devices such as fluidization pads, vibrators, bin activators, air fluidization, or RotoCon.

Capacities can be designed from small process silos as low as 10 m3 to large-volume storage silos as large as 1000 m3, depending on customer requirements.

Yes. Indpro’s silos are designed to work seamlessly with pneumatic conveying systems, feeders, and other discharge equipment.
