Hoppers & Cones
Discharge hoppers with mass-flow cone geometry defined by the buyer's bulk-solids engineer. Flow behavior, arching and ratholing require material-specific engineering and validation.

01 / What We Fabricate
The Structure That Moves Bulk Material
Bulk material handling depends on geometry — the right cone angle and smooth walls so material flows instead of jamming. We fabricate the hoppers, chutes, and housings that move grain, feed, aggregate, and powders reliably.
Transfer Chutes
Chutes that guide material between conveyors, machines, and processes — with abrasion-resistant surfaces and liner provisions for high-throughput wear zones.
Feed Housings & Ducting
Feed equipment housings, grain-handling enclosures, and ducting — the sheet metal structures that contain and direct bulk material through the process.
Outlets, Flanges & Supports
Discharge outlets with gate/valve mounting flanges, connection flanges, access points, and structural supports — sized to integrate your flow equipment.
Our scope: the sheet metal structure
We fabricate the hopper, chute, and housing structure — cones, bodies, transfer chutes, ducting, outlets, flanges, and supports — laser-cut, formed, welded, and finished, ready for integration. Bought-out components such as slide gates and rotary valves, screw and belt conveyors, level sensors, dust-extraction systems, actuators, and controls are integrated by you or your assembly partner. We build the structure with mounting flanges and provisions sized to your flow equipment.

03 / Technical Capabilities
Engineered to Flow, Built to Last
A hopper or chute has to flow material reliably, resist the wear of abrasive bulk, and integrate the flow equipment. Here's what we fabricate to.
| Materials | Carbon/galvanized steel; 304/316 stainless; AR400/AR500 abrasion-resistant plate |
|---|---|
| Flow Geometry | Buyer-defined geometry from bulk-solids flow analysis and released drawings |
| Wear Resistance | AR plate and liner provisions in high-wear zones — chutes and impact points |
| Discharge | Outlets with gate/valve mounting flanges; complete gravity discharge design |
| Connections | Flanged connections, access points, inspection openings, and structural supports |
| Reinforcement | Stiffeners and bracing for material load and structural integrity |
| Sanitary Option | Smooth, cleanable stainless construction for food and pharmaceutical handling |
| Finishing | Powder coat, galvanizing, or e-coat; stainless polish for sanitary use |
| Applications | Grain, feed, aggregate, fertilizer, powders, cement, minerals — ag and industrial |
We fabricate the structure to your material and flow design. Slide gates, rotary valves, conveyors, level sensors, dust extraction, and controls are integrated by you or your assembly partner.
04 / Manufacturing Process
From Sheet to Bulk Handling Structure
A hopper or chute lives or dies on flow geometry and wear resistance. Our process delivers a structure that flows reliably and survives abrasive material.
01
DFM & Flow Design
Review your material, throughput, and flow needs — confirm material, cone geometry, wear strategy, and the gate/valve and conveyor integration plan.
02
Laser/Plasma Cutting
Laser or plasma cutting of cone developments, chute sections, panels, and flanges — including AR plate for wear zones.
03
Forming & Rolling
Press-brake forming and rolling of cones, chute sections, and bodies — accurate geometry for proper mass flow and clean assembly.
04
Welding & Assembly
Welding cones, bodies, chutes, flanges, and supports — with smooth internal welds for flow and structural welds for material load.
05
Finishing
Powder coat, galvanizing, or e-coat for corrosion resistance — or stainless polish for sanitary applications.
06
Inspection
Dimensional inspection of geometry and flanges, weld quality, and finish check before delivery for your flow- equipment integration.
05 / Why It Matters
What Makes a Hopper or Chute Work
Bulk handling fails when material jams or wears the structure out. Four things separate a hopper that flows reliably from one that blocks and breaks.
Flow Geometry
The cone angle and wall smoothness determine whether material flows or jams. Mass-flow geometry prevents arching and ratholing — the blockages that stop production.
Wear Resistance
Abrasive bulk material wears through ordinary steel. AR400/AR500 plate and liner provisions can be reviewed against the buyer's wear and maintenance targets for chutes and impact points.
Complete Discharge
Material left in the hopper is waste and a contamination risk. Smooth walls and correct geometry ensure full discharge and easy cleaning — critical for food and feed.
Integration Fit
Gates, valves, and conveyors must mount precisely. Correct flanges and provisions sized to your flow equipment make the whole handling system work as one.

09 / FAQ
Hopper & Chute FAQ
Do you supply complete handling systems or just the structure?
We fabricate the sheet metal structure — hoppers, cones, transfer chutes, feed housings, ducting, outlets, flanges, and supports. Slide gates and rotary valves, screw and belt conveyors, level sensors, dust-extraction systems, actuators, and controls are integrated by you or your assembly partner. We build the structure with mounting flanges and provisions sized to your flow equipment.
What is mass-flow geometry and why does it matter?
Mass-flow geometry means the cone angle and wall smoothness are designed so all the material moves together and discharges completely, rather than bridging (arching) or channeling (ratholing). It prevents the blockages that stop production and ensures complete, clean discharge — which we engineer to your material's flow properties.
How do you handle abrasive materials?
For abrasive bulk like aggregate and minerals, we use AR400/AR500 abrasion-resistant plate and liner provisions in high-wear zones such as chutes, impact points and discharge areas. Actual wear, service life and maintenance depend on material, duty cycle and liner design; no fixed improvement is claimed.
Can you build sanitary hoppers for food or pharma?
Yes — we build 304/316 stainless hoppers with smooth, cleanable surfaces and sanitary welds for food, feed, and pharmaceutical handling, ensuring complete discharge and easy cleaning, applying the same hygienic fabrication discipline as our stainless worktable and medical work.
Can you match our flow equipment and layout?
Yes — send us your material, throughput, and the gates, valves, and conveyors you'll integrate, and we'll fabricate the hopper or chute with the right geometry, mounting flanges, and provisions sized to fit your flow equipment and layout.
What's your minimum order quantity?
We support everything from a single custom hopper to production programs. Send us your material and design requirements and we'll confirm MOQ and pricing for your project.
