Prefabricated assembled steel beams

Description

Prefabricated Assembled Steel Beams are high-performance structural components designed for fast, efficient, and high-precision construction in industrial buildings, commercial structures, warehouses, bridges, and modular steel structures.
Manufactured using high-grade steel such as Q355, Q460, S355, S460, ASTM A36, A572, the beams are fabricated, welded, drilled, and pre-assembled in the factory to ensure exceptional accuracy and rapid on-site installation.
These steel beams can be supplied as:
H-Beams / I-Beams
Welded Built-up Beams
Box Beams / Plate Girders
Tapered or Straight Beams
Customized composite beams
Their modular nature makes them ideal for projects requiring high speed, high load capacity, and high reliability.
