I-Beam: The Best Structure Selection of 150-120 Ton Large Tonnage Weighing Scales

Truck scales are massive industrial scales designed specifically for weighing large vehicles such as trucks, trailers, and construction equipment. Truck scales are constantly subjected to heavy use in demanding environments such as large mixing plants, cement plants, mines, and highway inspection stations. To withstand these conditions, reliable weighing performance and exceptional durability are required. For truck scales with capacities ranging from 150 to 200 tons, we recommend the I-beam structure.

I-Beam Structure Offers Several Key Advantages

  • Superior Strength and Stability: I-beams are known for their high strength-to-weight ratio. Their distinctive H-shaped profile allows them to efficiently distribute weight across the entire scale platform, ensuring that the scale can withstand the massive weight of these behemoth trucks without compromising structural stability. This results in a more consistent and reliable weighing experience.
  • Enhanced Durability: The I-beam structure distributes weight uniformly, reducing stress on individual weighing components within the scale. This reduces wear and tear, resulting in a stronger and longer-lasting scale. This means fewer future repairs and replacements, saving you both time and money on maintenance costs.
  • Accurate Weighing Performance: The I-beam structure’s ability to distribute weight evenly adds to the scale’s overall accuracy. The I-beam design, which reduces stress and deflection on the weighing platform, contributes to consistent and reliable weight measurements, even for these extremely heavy vehicles.

Selecting the Right I-Beam Configuration

To optimize your I-beam truck scale for your specific needs, we offer a range of beam options based on weighing weight and frequency of use. You can choose from I-beam sizes such as 30#, 32#, or 36#, or select A-type or B-type beams for customized strength profiles.

Selecting the Right Scale Body Panel

We also offer a variety of scale body panel thicknesses to further tailor the scale to your application. Panel options include 10mm, 12mm, 14mm, 16mm, 18mm, and 20mm, allowing you to find the ideal balance between weight capacity and cost.

AdvantagesThe I-beam is used as the main beam of a car scale, and the ultra-wide section and columns form a strong supporting scale body. The scale platform is not easily deformed and has high strength. It is the preferred choice for large tonnage and high-frequency weighing.


Truck scales used in large mixing plants, cement plants, mines, highway inspection stations, and other locations requiring frequent and extensive weighing must provide reliable weighing performance and durability. Our company recommends using an I-beam structure truck scale for trucks weighing 150-200 tons. The I-beam structure can serve as a strong supporting scale body. The production cost of the I-beam scale body is relatively high, so it has not become a popular variety in the market. However, its excellent load-bearing performance ensures long-term stability and assures metrological performance.
