What Kotzur does

Kotzur is a third-generation, family-owned Australian industrial manufacturer (founded 1953 by Ray Kotzur as Modern Engineering and Construction Co Pty Ltd, current ownership held by Andrew and Michelle Kotzur) specialising in bulk solids storage, handling, and processing equipment. Its product portfolio spans storage silos (transportable, on-ground, elevated, fertiliser, drying, feed and pellet, field bin, seed, and unsealed variants), handling systems (drag and screw conveyors, screw feeders, bucket elevators, distributors, grain spouts, silo unloaders, road pits, tubular belt conveyors, slide gates, screw flighting), and processing equipment (wetting screws, silo aeration with proprietary controller, Hawk roller mills, grain aspiration, CSIRO co-developed fumigation boxes, rotary scalpers, cyclones, and weighing systems). Engineering differentiators include gas-tight silos certified to AS 2628, a patented drying cone/plenum delivering up to 75% energy savings versus conventional drying, triple load-cell weighing accuracy of ±0.05 kg/s, and smooth-wall stainless silos for food-grade applications.

Revenue is generated predominantly through project-based, custom-engineered sales of large bulk solids storage and handling facilities to enterprise and mid-market customers in the agricultural, mining, and manufacturing sectors, supplemented by a smaller e-commerce channel for spare parts, consumables, and grain testing equipment. Operations run from a headquarters and primary silo factory at Walla Walla NSW (60 Commercial Street), a state-of-the-art Charlton QLD manufacturing facility opened 2023 (handling processing equipment, aeration fans, and handling equipment), and a Northam WA office, with combined headcount of approximately 200. The proprietary K-Rail fencing line is sold through a network of regional Australian distributors, and small-quantity components are sold direct through the Kotzur Online storefront. The business is family-controlled with no disclosed external shareholders or institutional funding, holds Australian Made Campaign registration, and complies with multiple Australian Standards governing structural, wind, seismic, and gas-sealing design.

• B. Keogh & Sons Manufacturing Pty LtdcoreTechnology or Integration · 1 January 2017Kotzur acquired all intellectual property owned by the Bendigo-based entity B. Keogh & Sons Manufacturing Pty Ltd in 2017. This acquisition added manufacturing capabilities and product IP to the Kotzur portfolio, strengthening their position in the bulk solids storage market.
• CSIROcoreStrategic or Co-development Partner · 1 January 2010CSIRO and Kotzur jointly undertook fumigation trials and developed the Kotzur fumigation box technology. The unit was designed and developed in 2010 in conjunction with CSIRO fumigation trials. Research results demonstrated that the fumigation box achieves required phosphine concentration distributed throughout all parts of the silo within 24 hours.
• Australian Made Campaign Ltd (AMC)coreOthersKotzur Group Pty Ltd is a registered member of the Australian Made Campaign Ltd and is approved to bear the official green-and-gold kangaroo logo. The logo is a registered trademark under Australian Consumer Law, qualifying Kotzur to market products as Australian made.

Others

• GrainCorp: Australia's largest listed grain handler and bulk storage operator, owning/operating extensive upcountry grain silos and bulk handling sites nationally. Adjacent rather than directly competitive — both serve Australian bulk grain storage, but GrainCorp owns the network while Kotzur manufactures the equipment that goes into it.

Direct peers

• Sioux Steel Company: US-based family-owned manufacturer of grain bins, hopper tanks, and bulk storage structures for agriculture and industry. Direct peer as a silo/hopper manufacturer with overlapping end customers (grain farmers, agricultural operations) and similar project-based sales to mid-market/enterprise agricultural accounts.
• Sukup Manufacturing: US-based family-owned manufacturer of grain storage bins, dryers, and material handling equipment with proprietary grain bin designs. Closely comparable as a vertically integrated family-owned silo manufacturer with similar custom-engineering ethos; operates at significantly larger scale but in a parallel niche — bulk grain storage and handling.
• Behlen Manufacturing & Engineering: Australian steel fabrication business with bulk storage, silos, and structural steel offerings headquartered in Newcastle. Comparable family-built industrial manufacturer serving Australian agricultural and infrastructure customers with similar custom-fabrication capabilities and product categories to Kotzur.
• Ahrens: Australian family-owned steel fabrication and engineering group with grain silo and bulk materials handling operations headquartered in South Australia. Directly competes with Kotzur in Australian agricultural silos and bulk storage structures with overlapping project-based, custom-engineered sales model.
• Westeel (Westeel Group / Vicwest): Canadian manufacturer of steel storage bins, silos, and bulk material handling equipment for agriculture and industry. Direct product overlap with Kotzur (steel silos, handling equipment) serving comparable grain and industrial bulk solids customers across Canada and North America, with similar project-based enterprise sales.

Broad incumbents

• Brock Grain Systems (CTB): US-headquartered global grain storage and handling brand owned by CTB, a Berkshire Hathaway company. Directly competes with Kotzur in grain bins and bulk storage equipment with established international distribution; serves as a scaled incumbent benchmark for Kotzur's go-to-market in large agricultural accounts.
• Ag Growth International (AGI): Global manufacturer of grain storage, handling, and processing equipment serving agriculture across North America, EMEA, and APAC. Operates as a much larger incumbent with overlapping product categories (silos, conveyors, aeration) and serves similar bulk-grain end customers as Kotzur, but with substantially broader portfolio and geographic reach.
