Heavy Truck Steel Bar Parts: Cold-Rolled and Hot-Rolled Steel Options in Round, Square, and Hexagonal Profiles
When it comes to the durability and performance of heavy trucks, steel bar components are critical for achieving strength, reliability, and long-lasting performance. Whether in the manufacturing of axles, suspension systems, steering components, or structural supports, the right type and shape of steel bars play an essential role.
We specialize in providing cold-rolled and hot-rolled steel bars, expertly tailored for heavy truck applications. Our extensive selection includes round bars, square bars, and hexagonal bars, each meticulously designed to meet the diverse and demanding needs of the heavy trucking industry.
Cold-Rolled Steel Bars
Cold-rolled steel bars offer superior surface finish, enhanced precision, and tighter dimensional tolerances, making them an ideal choice for heavy truck components that require high accuracy and smooth aesthetics. Whether you need round, square, or hexagon bars, cold-rolled options ensure exceptional strength-to-weight ratios, making them perfect for crucial truck parts that demand both resilience and lightweight properties.
Hot-Rolled Steel Bars
For heavy-duty applications requiring unmatched toughness and flexibility, hot-rolled steel bars are an optimal solution. Produced at high temperatures, these bars exhibit excellent formability and robustness, making them ideal for heavy truck parts that endure significant stress and extreme conditions. Our hot-rolled round, square, and hexagon bars offer consistent performance in challenging environments.
Available Shapes for Heavy Truck Parts
- Round Bars: Widely used for shafts, pins, and couplings in heavy trucks, our round steel bars provide a balance of strength, durability, and machinability.
- Square Bars: Perfect for structural support and key components that require consistent performance under load, square bars provide excellent stability and resistance.
- Hexagon Bars: Commonly applied in heavy truck fasteners, hex bars offer precise geometry and superior torque distribution for secure high-stress applications.
Trucks are classified based on their “Gross Vehicle Weight Rating” (GVWR).
This is a rating system used by manufacturers and governments that limit the maximum amount of weight a truck can haul including, the truck, fuel, load on the truck and the passengers. Trucks are classified from Class 1 small pickups 
with a GVWR of 6,000 lbs. or less to class 8 with a GVWR of 33,001 lbs. or greater and everything in between.
While the primary function of the passenger car is to haul people the primary application of the truck is to haul things and deliver them safely. As the class of the truck increases the size and weight of the parts that go into the vehicle increase.
Eaton Steel Bar Company (ESBC) supplies all classes of trucks from the pickup you may be driving to the class 8 truck which delivers our steel daily, just-in-time to our customers. Hot rolled and cold finished rounds, squares and hexagons are used to produce a variety of parts from the smallest hydraulic connections to large gears and shafts. A full spectrum of commonly stocked grades are used as well as customized grades for unique applications. A full range of sizes produced or distributed by ESBC are used to produce, high quality, parts for the trucking industry. Below is a list of typical parts produced from Eaton Steel Bars. or less to class 8 with a GVWR of 33,001 lbs.
