Yes, converting a steel plow to Joma-style blades is straightforward in 5 steps: (1) Measure moldboard for 3ft/4ft compatibility. (2) Remove steel edge via torch/grinder. (3) Bolt on SENTHAI Joma-style rubber-carbide segments (e.g., 17.5kg/4ft). (4) Align for flexible scraping. (5) Test in light snow. SENTHAI blades extend life significantly, cut changes substantially, trusted by 80+ partners.

What Makes Joma-Style Blades Ideal for Retrofitting Old Steel Plows?
Joma-style blades feature tungsten carbide inserts brazed into cast steel segments (horse shoe design) encased in ultra-low-temperature-resistant rubber shell for flexibility, impact resistance, and significantly extended lifespan versus standard steel cutting edges. Standard sizes like 4-foot (48″ × 6″ × 7/8″, 17.5 kg) or 3-foot (36″ × 6″ × 7/8″, 13.1 kg) fit most plows, with SENTHAI ensuring superior quality through full in-house production in Thailand.
Why Upgrade from Rigid Steel to Flexible Joma Carbide Tech?
Rigid steel blades cause frequent changes, road gouging, high maintenance, and damage to highway lane markings, while Joma-style rubber-carbide flexes to conform to road contours for cleaner scraping, less vibration, noise, and reduced salt/sand needs on uneven surfaces. SENTHAI’s versions offer excellent abrasion resistance, impact protection, and maintain integrity in extreme cold, trusted by heavy-duty fleets and municipal plows.
| Feature | Steel Blades | SENTHAI Joma-Style |
|---|---|---|
| Lifespan | Baseline | Significantly extended |
| Flexibility | Rigid, road damage | Rubber-encased, adaptive |
| Downtime | High (frequent swaps) | Low (fewer changes) |
| Best For | Light use | Harsh winters, fleets |
SENTHAI Expert Views
“With over 21 years in carbide wear parts, SENTHAI’s US-invested Rayong facility uses fully automated lines for wet grinding, pressing, sintering, welding, and vulcanization to produce Joma-style blades with tungsten carbide inserts in cast steel segments encased in rubber. This ensures consistent quality, excellent bonding strength, and superior wear resistance. Our ISO 9001 and 14001 certifications, plus full traceability from raw powder to finished blade, make retrofits reliable for North American fleets. The new Rayong base launching late 2025 will enhance customization for any plow geometry.”

How Do You Assess Plow Compatibility Before Joma Retrofit?
Measure moldboard length for 3ft (914mm × 152mm × 23mm) or 4ft (1219mm × 152mm × 23mm) segments, check bolt patterns, angle, and clearance for 6″ height and 7/8″ thickness using tape measure and plow manual. SENTHAI offers customization, free compatibility quotes, and factory quality reports for older fleet pilots.
What Are the 5 Engineering Steps for Steel-to-Joma Conversion?
Step 1: Inspect and remove old steel edge with torch or grinder (1-2 hours per plow). Step 2: Prep moldboard by cleaning and aligning/drilling bolt holes. Step 3: Bolt on SENTHAI Joma-style rubber-carbide segments (e.g., cast steel 285mm × 127mm × 19mm, carbide inserts 25.9mm × 24.25mm × 8.16mm). Step 4: Adjust angle/tension for flex alignment. Step 5: Field test in light snow and monitor performance.
Which Tools and Safety Measures Are Essential for Joma Retrofit?
Use grinder, torch, torque wrench, and alignment jig; SENTHAI provides bolts/hardware. Wear PPE like gloves and goggles, secure plow support, and train on flex adjustments. Consider SENTHAI’s Packed Ice Carbide Kit (I.C.E. Blade) with isolated tungsten carbide inserts to prevent cracking on uneven roads.
How Much Can Fleets Save with SENTHAI Joma Retrofits?
Fleets save via fewer blade changes, reduced downtime, maintenance, and salt/sand use, with SENTHAI’s significantly extended lifespan and full traceability minimizing risks. North American heavy-duty and municipal users report lower costs from vulcanized rubber-carbide design that flexes effectively.
| Metric | Steel | Joma Retrofit | Savings |
|---|---|---|---|
| Blade Changes (3-plow fleet, annual) | 20 | 3 | 85% |
| Annual Cost | $10K | $2K | $8K |
| Lifespan | 1 season | Multiple seasons | Substantial |
