Mainstream Materials for the Scale Body Load-Bearing Frame
All-Steel Structure
This is currently the most widely used type, subdivided into three main steel profiles: U-shaped steel, channel steel, and I-beams.
U-shaped Steel: The industry's mainstream choice, employing a bridge-like structural design and full welding process. It boasts excellent overall rigidity and torsional strength. The fully sealed internal cavity is rust-resistant. After shot blasting and rust removal, it is coated with epoxy zinc-rich primer and marine-grade topcoat, providing strong corrosion resistance and a long service life. It is suitable for most heavy-duty industrial applications.
Channel Steel: Belonging to the third generation of weighing equipment, it features only two load-bearing beams at the bottom. The hollow structure in the middle results in weaker load-bearing capacity. It uses spot welding, and its overall strength is lower than U-shaped steel. It is mostly used in low-tonnage, low-frequency applications.
I-beams: Less commonly used in truck scales. Major domestic and international manufacturers generally do not use it as their primary material, only using it in small quantities in some special customized applications. Standard carbon steel must meet industry standards, with Q235B being a commonly used grade. It requires a yield strength of no less than 235 N/mm² to meet foundation load-bearing requirements.
Stainless steel: Specifically designed for highly corrosive environments, such as waste incineration plants and biodiesel plants. It resists corrosion from sewage, grease, and organic acids, has a service life more than twice that of ordinary carbon steel, and reduces long-term maintenance costs by more than 60%.
Reinforced concrete structures, commonly known as cement scales, use steel reinforcement to bear tensile forces and concrete to bear compressive forces. They offer advantages such as strength, durability, corrosion resistance, and cost savings on steel. Production cycles are longer than all-steel structures, making them suitable for highly corrosive outdoor environments such as chemical plants and ports.
