Custom Steel Truss Joist for Commercial and Industrial Floor Systems

The Steel Truss Joist, also known as an Open Web Joist, is a high-performance structural component widely used in modern commercial and industrial buildings. Designed for long-span floor and roof applications, it provides excellent strength-to-weight efficiency, allowing for larger open spaces and more flexible architectural layouts.

At Hangzhou FAMOUS Steel Engineering Co., Ltd., we specialize in the custom design, engineering, and fabrication of steel truss joists tailored to meet each client’s project requirements. Whether for office complexes, shopping centers, warehouses, or multi-story buildings, our truss joists ensure structural integrity, easy installation, and long-term reliability.

Product Features

• Lightweight & Strong:
  The open web configuration uses triangulated steel members to deliver maximum strength with minimal material weight, reducing both cost and construction load.

• Efficient MEP Integration:
  The open web design allows mechanical, electrical, and plumbing (MEP) systems to pass through without additional floor penetrations, simplifying installation and saving time.

• Custom Fabrication:
  Every truss is engineered to match project-specific spans, loads, and connection requirements. We can provide detailed design drawings, 3D modeling, and fabrication according to EN, AISC, or AWS D1.1 standards.

• Precision Manufacturing:
  Our factory is equipped with CNC cutting, robotic welding, and full-scale assembly lines to ensure accuracy, consistency, and durability across all production batches.

• Surface Finishing:
  Trusses can be hot-dip galvanized, epoxy-coated, or powder-coated based on the project’s environmental and aesthetic needs.

Applications

Steel truss joists are ideal for:

• Commercial and industrial floor systems

• Roof structures in warehouses, factories, and exhibition halls

• Mezzanine and platform support structures

• Long-span buildings require clear open spaces

Their combination of strength, lightweight design, and modular assembly makes them suitable for both new construction and retrofit projects.
