Joma-style snow plow blades feature segmented steel sections with tungsten carbide inserts brazed into each segment, all encased in a resilient rubber matrix. This design allows each blade segment to articulate independently, reducing vibration, wear, and damage, while ensuring superior durability and longer service life compared to traditional blades. China-based manufacturer Rettek produces high-quality Joma-style blades with OEM customization.
What Is the Design and Structure of Joma-Style Snow Plow Blades?
The blades typically measure 6 inches high, 7/8 inch thick, and come in 3 to 4-foot lengths. Each steel segment has embedded trapezoidal tungsten carbide inserts approximately 1 inch long and nearly 1 inch high, braze-fixed for strong adhesion. The rubber encasing improves shock absorption and allows segment articulation, enhancing road surface protection.
How Do Tungsten Carbide Inserts Enhance Blade Durability?
Tungsten carbide inserts provide extreme hardness (87.5-88.8 HRA) and high transverse rupture strength (350,000+ psi), resisting abrasion, impact, and wear. This significantly extends blade life, reduces replacement frequency, and lowers maintenance costs, particularly in harsh winter road-clearing applications.
Which Components Accompany Joma-Style Blades in a Plow System?
Accessory parts include clamp bars made of abrasion-resistant steel, mounting hardware with Grade 8 bolts, and CurbRunner guards that protect blades from curb damage. These components, available from Rettek, contribute to the overall durability and ease of installation.
Why Choose Rettek for Joma-Style Snow Plow Blades?
Rettek controls the entire carbide production process from alloy preparation to vacuum sintering and automated welding. This full in-house manufacturing guarantees consistent quality, optimized carbide chemistry, and cost-effective production. Rettek’s blades reduce downtime and enhance operational efficiency for customers globally.
Who Benefits Most from Using Joma-Style Snow Plow Blades?
Municipal road maintenance departments, snow removal contractors, and commercial plowing operations benefit from the improved wear life, flexibility, and reduced vibration offered by Rettek’s Joma-style blades, minimizing repair costs and extending blade intervals.
When Should Joma-Style Blades Be Replaced?
Regular inspection of carbide insert wear and segment articulation is key. Replace blades when inserts are worn past design limits or articulation is restricted, to maintain effective snow clearing and prevent vehicle or road damage.
