Steel Material Guide
Understanding Hardox steel options for dump truck body construction
Why Steel Selection Matters
The choice of steel material significantly impacts your dump body's durability, weight, and payload capacity. ROX4D uses premium Hardox steel options to deliver the optimal balance of strength and weight savings.
Hardox is a wear-resistant steel known for exceptional hardness and impact resistance, making it ideal for demanding applications like aggregate hauling, construction debris, and rip rap transport.
Hardox 450 Standard
Proven field performance with established thickness standards. Lower material cost per pound.
Hardox 500 Tuf Lightweight
Superior hardness and toughness allows thinner sections. Significant weight savings for more payload.
27 J (20 ft-lb) at -20°C (guaranteed)

Hardox Steel Thickness Comparison Chart
Comparing Hardox 450 vs 500 Tuf performance across different applications
| Application | Hardox 450 Standard Option | Hardox 500 Tuf Lightweight Option | Performance Comparison 500 Tuf vs Thicker 450 |
|---|---|---|---|
Aggregate Materials Sand, Dirt, #1 & Smaller Crushed Stone/Gravel | 3/16" Floor + 5/32" Walls | 5/32" Floor + 1/8" Walls ~18% lighter | 500 Tuf Better 500 Tuf provides ~7% better dent resistance plus 18% weight savings for increased payload |
Hot Asphalt Hot Mix, Paving Materials | 3/16" Floor + 5/32" Walls Field proven standard | 5/32" Floor + 1/8" Walls ~18% lighter | 500 Tuf Better 500 Tuf offers superior hardness and impact resistance while being 18% lighter |
Class I Rip Rap 6-12" Angular Rock (~125 lbs typical) | 3/16" Floor + 5/32" Walls Adequate for Class I | 5/32" Floor + 1/8" Walls ~18% lighter | 500 Tuf Better 500 Tuf's superior hardness fully compensates for thinner material, providing equal durability at 18% less weight |
Class II Rip Rap 12-18" Angular Rock (~350 lbs typical) | 1/4" Floor + 3/16" Walls For heavy impact resistance | 3/16" Floor + 5/32" Walls ~20% lighter (~750lbs extra payload) | Similar Performance 500 Tuf matches 450's durability with 20% weight reduction - higher hardness offsets thinner walls |
Class III Rip Rap 18-24"+ Angular Rock (~750 lbs typical) | 5/16" Floor + 1/4" Walls Heavy-duty specification | 1/4" Floor + 3/16" Walls ~23% lighter (~1150lbs extra payload) | Similar Performance 500 Tuf delivers equal protection with 23% weight savings - ideal for extreme impact while maximizing payload |
Construction Debris Demo Material, Broken Concrete, Mixed | 1/4" Floor + 3/16" Walls Some denting at 3/16" 1/4" for heavy use | 3/16" Floor + 5/32" Walls ~20% lighter (~750lbs extra payload) | 500 Tuf Better 500 Tuf's superior toughness handles sharp impacts better than 450, plus delivers 20% weight savings |
Superior Durability
Both Hardox grades offer exceptional wear resistance and impact strength, ensuring your dump body withstands years of demanding use in the harshest conditions.
Maximum Payload
Hardox 500 Tuf delivers 18-23% weight reduction compared to Hardox 450, allowing you to carry more payload per trip while maintaining equivalent durability for most applications.
