Steel Side Wall for Trailers

Heavy-Duty ST52 Steel Dropside & Side Cover Profiles — Engineered for High Yield Strength, Maximum Rigidity, and Long-Lasting Durability.

Upgrade your commercial trailers, tippers, and cargo bodies with Bomanti’s high-strength ST52 steel side wall profiles. Precision-formed to provide maximum structural stability, these roll-formed steel side boards are specially designed for the front, rear, and side drop-down covers of semi-trailers, dropside trucks, and agricultural trailers.

Manufactured from ST52 (S355) high-tensile structural steel, these profiles offer superior resistance to impact, flexing, and heavy cargo loads compared to standard commercial mild steel profiles.

Key Features & Benefits

  • High Tensile ST52 Grade Steel: Built using premium ST52 structural steel, offering enhanced yield strength to withstand intense side-wall pressure from bulk materials and heavy cargo.

  • Precision Press-Formed Geometry: Features stiffening ribs and profiled corrugations that enhance structural rigidity without adding unnecessary weight to your trailer.

  • Versatile Modular Profile: Specifically engineered for front bulkhead lower sections, rear gate sections, and full-length side dropside covers.

  • Seamless Fitment: Standardized 33mm top and 29mm/15mm bottom joint dimensions allow clean alignment, welding, and sealing with standard trailer side dropside frames and hinges.

  • Export-Grade Quality: Designed to meet European and international trailer manufacturing standards, ready for custom length cutting and surface priming/galvanizing.
