Scenario: a contractor with several pickups and a Boss-style plow wants to choose an edge material. Direct answer: choose by the surfaces you plow most and by how costly a mid-season change is for you. “Boss-style” is trade shorthand for a plow family, so confirm exact model and dimensions with the supplier. No brand-specific results are claimed.
| Option | Where it tends to fit | Trade-offs to weigh |
|---|---|---|
| Steel | Short routes, rough budgets, light use | Wears sooner in general; more frequent changes |
| Poly (rubber-like) | Pavers, stamped concrete, painted markings, lots with soft surfaces | Quieter and gentler on surfaces, but wear depends on compound and scraping quality may differ |
| Carbide-faced | Longer routes on abrasive or rough pavement | Higher price and weight; hard contact; chip risk on severe impact |
Questions to settle first
Poly, steel and carbide answer different questions, so start from the route rather than the material.
- What share of your accounts are delicate surfaces versus plain asphalt? The mix, not the total, decides which edge earns its cost.
- How many pushes does a set of edges get in a normal winter for you? Push count drives wear more than hours do.
- What does a mid-season change cost in labour and lost route time? The cheapest edge per unit can be the most expensive per season.
- Can the truck and plow mount handle a heavier edge? Carbide adds weight where the plow is already loaded.
A way to compare costs
Cost per push is the only comparison that survives a mid-season change.
- Cost per set ÷ number of pushes per set gives cost per push for edge wear alone.
- Add the cost of each change (labor, downtime).
- Use your own counts, not a brochure’s, and label any assumption.
Fit checks
Three measurements decide whether an aftermarket edge fits, and all three are cheaper to take than a return.
- Overall length, thickness and bevel of the old edge. The bevel angle is the part most often left out.
- Bolt hole count, spacing and shape. Slot versus round matters as much as spacing.
- Photos with a tape measure, sent for written confirmation. A supplier who confirms in writing owns the fit.
Common mistakes
Edge-choice mistakes usually start with one account and get generalised.
- Choosing carbide for every account because one account was rough. You pay the carbide premium on routes that do not need it.
- Ignoring the weight of the edge on a light truck. A heavier edge changes handling and mount load.
- Judging poly on a rough lot or carbide on a paver site. Each material was tested outside the conditions it suits.
- Not keeping the old edge’s measurements. The next order then starts from nothing.
Each of these can be avoided with a short checklist at the time of ordering and a log during the season.
What to record
For each truck, note the edge type, fitting date, hours or pushes, height at inspection and any chipping. A season of notes will tell you more about the right material for your accounts than any general table.
Boundary: general tendencies only; no brand-specific or measured results. Confirm fit with the supplier and your plow manual.
