What This Part Is And Why It Is Made This Way
Grate and panel castings have to keep an open area while carrying load across an unsupported span, which puts every rib in bending. Rib section and spacing are the design, and the casting has to reproduce them exactly.
Panels are cast in grey or ductile iron, including EN-GJL-200 + 3%Cr where extra wear resistance is needed.
What You Get From This Route
Rib geometry reproduced consistently so open area stays as designed.
Chromium alloyed grey iron available for abrasive duty.
Shell process available where surface and dimensional accuracy matter.
Application Scenarios
- Screening and sizing panels
- Walkway and floor grates in plant
- Air distribution plates
- Wear panels in material handling
Who It Is For
- Bulk handling and screening equipment builders
- Plants replacing worn grid panels
- Contractors specifying plant walkways and grates
Technical Features
- Grey iron, ductile iron and EN-GJL-200 + 3%Cr options
- Green sand, resin sand and shell processes
- Weight 0.2 kg - 2000 kg
- Dimensional control on frame fitting features
What Buyers Run Into Without This Specification
- Ribs wear thin and the open area grows beyond specification.
- Panels do not sit flat in the frame and rock under load.
- Plain grey iron wears out quickly in an abrasive position.
Published Material Weight And Process Data
Figures below are the published capability for cast iron. Part specific values — tolerance on individual features, finish, packing — are confirmed at drawing review and marked TBC until then.
| Grey Iron | EN-GJL-150 / 200 / 250 / 300 |
|---|---|
| Ductile Iron | EN-GJS-400 / 450 / 500 / 600 / 700 / 800 |
| ADI | ADI800-10 / ADI1200-3 |
| Weight Range | 0.2 kg - 2000 kg |
| Process | Green sand process; resin sand process; shell process |
| Selection Basis | Grade and moulding route matched to customer drawing and application scenario |
| Part Specific Tolerance | TBC — confirmed against the customer drawing |
| Minimum Order Quantity | TBC — depends on the process route selected |
| Lead Time | TBC — confirmed with the production base at quotation |
How The Part Is Made And Checked
- Green Sand — High volume production of repeat parts at the lowest tooling cost.
- Resin Sand — Larger parts and complex cavities where dimensional stability matters more than cycle time.
- Shell Process — Better surface and dimensional accuracy for mid size batches.
Quality management is based on ISO 9001 and covers supplier management, raw material inspection, production process control and final inspection. Inspection results are archived and traceable.
Options And Alternatives
Parts are produced to the customer drawing rather than to a fixed catalogue item, so material grade, machining scope, surface treatment and packing are all specified per order. Machining, dimensional control, surface treatment and necessary pre-assembly can be added to the same supply route.
Where another process family would suit the part better — for example a forging in place of a casting for a shock loaded connector — that comparison is raised during drawing review rather than after tooling is committed.
How To Specify This Part
Give the frame dimensions along with the panel drawing, and say what passes through the openings. Both the open area and the wear rate depend on that material, and it changes whether a chromium alloyed grade is worth specifying.
- Send the drawing with material, quantity, quality standard and target delivery date.
- State the inspection class and the zones it applies to, rather than a general note.
- Confirm the packing requirement and the lifting equipment available at the destination.

Is a wear resistant iron grade available?
EN-GJL-200 + 3%Cr is used in the high alloy business for wear and heat exposed parts and can be considered for abrasive panel duty.
Can panels be matched to an existing frame?
Parts are produced to the customer drawing. Please supply the frame dimensions together with the panel drawing.
What do you need to prepare a quotation?
Drawings, material, quantity, quality standard and target delivery date.
Which inspection is included?
The inspection scope is agreed during drawing review. Better surface and dimensional accuracy for mid size batches.
