In North and Central/South America, many builders, developers, and structural engineers are actively using Steel Floor Joist systems—also known as Open Web Steel Joist (OWSJ)—for modern construction projects. Hangzhou FAMOUS Steel Engineering Co., Ltd. has accumulated extensive experience in this field, delivering high-performance floor joist systems to numerous projects and earning the trust of global clients.
At FAMOUS, we understand that every project needs a floor system that is lightweight, strong, easy to install, and adaptable. Our Steel Floor Joist products meet these exact needs, helping builders achieve efficient construction and cost control while maintaining exceptional structural reliability.
Product Features
FAMOUS Steel Floor Joist adopts an open-web truss design, formed by top and bottom chords connected with diagonal web members. This design minimizes self-weight while maintaining high load-bearing strength, making it ideal for long-span floor systems.
The open-web geometry allows easy passage of electrical wiring, plumbing, and HVAC systems without additional cutting or drilling, reducing installation time and costs. Each joist can be customized in terms of height, span, and web configuration, with optional hot-dip galvanizing or protective coatings for enhanced corrosion resistance.
Lightweight yet strong, this system provides greater design flexibility, faster installation, and improved site efficiency — all essential advantages for modern prefabricated or modular construction.
Applications
Steel Floor Joists are a mature and widely accepted solution across North and Central/South America. They are extensively used in industrial buildings, logistics warehouses, commercial complexes, schools, and residential developments.
In warehouses and logistics centers, the system eliminates intermediate supports, allowing for larger open spaces. In residential and commercial buildings, its lightweight design minimizes dead load while maintaining strength, making it especially suitable for multi-story construction. For industrial plants and cold storage facilities, FAMOUS Steel Floor Joists provide stable structural performance and help accelerate project delivery.
Clients often come to us with clear design requirements because they recognize the proven advantages of this system in efficiency, stability, and long-term reliability.
Client Visit and Project Trust
Recently, a developer delegation from North America visited the FAMOUS factory to inspect their customized floor joist order. They were greeted with a full demonstration of our automated welding lines, precision cutting systems, and in-process quality control checkpoints. With their design drawings in hand, they reviewed beam dimensions, spans, and web configurations directly with our engineers.
During the visit, they observed our strict quality inspection process—checking weld precision, material straightness, and surface protection. One of the visitors commented, “It’s reassuring to see how much detail and control go into every single joist.”
By the end of the visit, the client team had full confidence in our products and decided to expand cooperation for their upcoming multi-level warehouse project. This transparency and professionalism are what make FAMOUS a trusted long-term partner for global customers.
