Galvanized Open Web Steel Joist (OWSJ) – High-Strength Truss Beam & Rafter for Flooring Support

Our Open Web Steel Joist (OWSJ) is a high-strength, hot-dip galvanized steel truss system designed for efficient load distribution in commercial, industrial, and institutional construction. The open web design allows seamless integration of MEP (mechanical, electrical, plumbing) services, reducing installation time and costs while maintaining structural integrity.

Key Features:

✔ High Load Capacity – Engineered to support heavy floor and roof loads with stability.
✔ Corrosion-Resistant – Hot-dip galvanized coating (Z275-Z600) for long-term durability.
✔ Lightweight & Efficient – Optimized design reduces material usage without compromising strength.
✔ Easy Installation – Pre-fabricated components with bolted connections for fast assembly.
✔ Customizable – Available in standard and custom spans (6m–24m) to fit project needs.

Technical Specifications:
