Snow Plow Edge Components

The diagram above shows a urethane cutting edge (shaded) sandwiched between a metal wear bar and the steel plow blade. Bolts, washers, and nuts clamp the poly edge securely in place. This bolt-on configuration allows easy replacement or reversing of the blade when one edge wears out. The urethane itself then behaves like a squeegee on the pavement: its flexibility lets the edge conform to surface irregularities and wipe clean much better than rigid steel. In practice, this means hitting bumps, grates, or curbs doesn’t tear up the roadway, and the operator feels less vibration in the cab.

• Typical Range (⅜″–1″): Most plow edges use material in this range. It provides a balance of strength and flexibility. Our sheets and bars include 0.375″, 0.5″, 0.75″, and 1.0″ thicknesses as standard.
  
• Up to 2″ or More: For heavy-duty blades, we can supply 1.5″–2″ thick urethane (or cut up to 3–4″ from sheet stock) as needed. The product listings show availability from 0.5″ up to 2″ in multiple widths. Thicker edges are useful on large plows or in very abrasive conditions.
  

• 80A–90A: A balanced hardness range for most snowplow edges. These durometers deliver good wear resistance without becoming too rigid, providing a mix of impact absorption and long life. An 80–85A blade will still flex under load, while 90A offers extra toughness.
  
• 90A–95A: Harder compounds for extreme-duty applications. Edges in the 90–95A range maximize abrasion resistance and wear life, ideal for heavy commercial or highway plowing where longevity is critical. (Above ~95A Shore A, urethanes approach the Shore D scale.)
  

• Sheet Stock: Cast urethane sheets (available in a variety of colors and durometers) are used to cut custom plow blades and scraper strips. Our standard sheet material is highly abrasion- and chemical-resistant. We stock sheets up to 4″ thick, with common thicknesses (⅜″, ½″, ¾″, 1″, etc.) available. Flat sheets allow you to punch or machine any blade shape to match your plow or scraper design.
  
• Bar / Block Stock: Square and round urethane bars serve as blanks for bolt-on edges. These solid bars (up to 8″ cross-section) are easy to cut to length and machine. Urethane bar stock is widely used for snowplow cutting edges, scraper blades, and other wear parts. For example, a ½″×6″×72″ bar can become a direct-replacement rubber edge. After cutting to length, you can bolt or bond the blank to a steel backing strip for a custom fit.
