ZSJH Steel provides project-specific Built-Up Steel Beam fabrication for industrial, commercial, warehouse, infrastructure, and heavy steel structure applications.

According to customer drawings and engineering requirements, we can complete plate cutting, beveling, assembly, welding, straightening, drilling, stiffener fabrication, connection plate installation, surface treatment, inspection, packing, and export preparation.

Product Specifications

Main Features

Custom Structural Dimensions

Built-up beams are not limited to standard mill sizes. Beam depth, flange width, web thickness, flange thickness, and overall length can be manufactured according to project requirements.

Suitable for Long Spans

Built-Up Steel Beams are commonly selected for structures requiring greater span capability and higher load-bearing performance than conventional rolled sections.

Tapered and Variable Sections

Tapered or variable-depth beams can be fabricated to optimize steel consumption while meeting structural design requirements.

Reinforced Structural Design

Stiffener plates, end plates, splice plates, brackets, gussets, and other reinforcement components can be integrated into the beam.

High Fabrication Flexibility

The beam configuration can be adjusted according to structural loading, connection requirements, transportation limitations, and installation conditions.

Multiple Surface Protection Systems

Surface treatment can be selected according to the service environment, including shot blasting, zinc-rich primer, finish coating, and hot-dip galvanizing.

Built-Up Steel Beam Fabrication Process

Raw Material Inspection → CNC Plate Cutting → Edge Preparation → Beam Assembly → Tack Welding → Automatic Welding → Straightening → Drilling → Stiffener Installation → Connection Plate Fabrication → Surface Treatment → Final Inspection → Packing

This controlled fabrication process helps maintain dimensional consistency, welding quality, and installation accuracy.

FAQ

What is a Built-Up Steel Beam?

A Built-Up Steel Beam is fabricated by welding separate steel plates together to form an I-shaped, H-shaped, tapered, or customized structural section.

Why use a Built-Up Beam instead of a rolled beam?

Built-up beams provide greater flexibility in beam depth, flange width, plate thickness, section shape, and load capacity when standard rolled sections cannot meet project requirements.

Can you manufacture tapered beams?

Yes. Tapered and variable-depth welded beams can be produced according to engineering drawings.

Can stiffeners and connection plates be added?

Yes. Stiffener plates, splice plates, end plates, brackets, gussets, and other connection components can be fabricated as part of the beam.
