ZSJH Steel provides customized built-up steel beam fabrication based on customer drawings, structural requirements, material specifications, and project standards. Our fabrication capabilities cover steel plate cutting, assembly, welding, drilling, stiffener installation, surface treatment, inspection, and export preparation.

Built-up steel beams are widely used in industrial buildings, warehouses, factories, logistics centers, multi-story structures, heavy steel structures, and long-span construction projects.

Product Specifications

Key Features

Customized Section Design

Built-up beams can be manufactured with customized beam depths, flange widths, web thicknesses, and plate thicknesses to meet specific structural load requirements.

High Load-Bearing Capacity

The combination of heavy steel plates and welded construction makes built-up beams suitable for large-span and heavy-load structural applications.

Flexible Fabrication

Straight, tapered, variable-depth, reinforced, and stiffened steel beams can be produced according to engineering drawings.

Precision Welding

Controlled welding processes help achieve stable structural connections between flange plates, web plates, stiffeners, and connection components.

Multiple Connection Options

End plates, stiffener plates, splice plates, brackets, bolt holes, and other connection details can be fabricated according to project requirements.

Surface Protection Options

Different corrosion-protection systems are available, including shot blasting, primer coating, finish painting, and hot-dip galvanizing.

Fabrication Process

Steel Plate Preparation → CNC Cutting → Plate Assembly → Tack Welding → Main Welding → Straightening → Drilling → Stiffener & Connection Plate Installation → Surface Treatment → Inspection → Packing

Each beam can be fabricated according to approved workshop drawings to help ensure dimensional accuracy and compatibility during site installation.

Quality Control

Quality inspections can be carried out throughout the fabrication process, including:

• Raw material verification

• Dimensional inspection

FAQ

What is a Built-Up Steel Beam?

A built-up steel beam is a structural beam fabricated by welding separate steel plates together to create an H-shaped, I-shaped, tapered, or customized cross-section.

What is the difference between a built-up beam and a rolled steel beam?

Rolled beams are produced in standardized sizes by steel mills, while built-up beams are fabricated from individual steel plates and can be customized in height, width, thickness, and section shape.

Can you manufacture beams according to our drawings?

Yes. Built-up beams can be fabricated according to customer structural drawings, shop drawings, BOMs, and technical specifications.

Can you produce tapered steel beams?

Yes. Tapered and variable-section built-up beams can be manufactured according to project requirements.
