Forged steel wheels carry the highest loads of any tread material and shrug off heat, weld spatter, chips and floor damage that destroy polymer wheels.
Paired with welded heavy-gauge brackets they form the RM-Extreme series for the toughest factory floors.
Material Grades & Properties
Forged Steel Grades We Machine
| Grade | Standard | Characteristics |
|---|---|---|
| Forged tread | machined | extreme loads |
Key Properties of Machined Forged Steel
- ✓Highest load of any tread (to 2000 kg per caster)
- ✓Shrugs off heat, weld spatter, chips
- ✓Needs steel plate or heavy concrete floor
Typical tolerances:Tread concentricity machined; static load tested
Applications for Forged Steel Parts
- machinery moving
- steel mills
- ovens
- die carts

Finishes
As-forged, zinc or painted
| Bracket finish | What it does | Specify it when |
|---|---|---|
| Zinc plating (blue/white) | Baseline corrosion protection | Standard dry indoor use |
| Chrome plating | Hard, decorative, easy to clean | Visible / cleanroom-adjacent equipment |
| Powder coating | Custom color, good corrosion resistance | Brand colors, outdoor-adjacent use |
| Stainless steel 304 | No plating to fail | Washdown, food, medical |
| Stainless steel 316 | Resists chlorides | Salt, brine, marine air, harsh cleaning chemicals |
Testing
Tread concentricity machined; static load tested
| Selection factor | Rule of thumb | Effect on performance |
|---|---|---|
| Load sizing | Total load ÷ 3 (not ÷ 4) | On uneven floors only three wheels carry the cart |
| Wheel diameter | Bigger rolls easier | Larger wheels cut push force and bridge gaps |
| Tread hardness | Softer = quieter, harder = easier rolling | Pick the softest tread that carries the load |
| Bearing choice | Precision ball for manual pushing, roller for heavy loads | Bearings dominate rolling resistance at high load |
| Swivel vs rigid | 2 swivel + 2 rigid is the standard cart setup | All-swivel carts wander; all-rigid carts cannot steer |
| Floor condition | Rough floors need bigger wheels and softer treads | Small hard wheels on bad floors destroy both |
