Floor Joists
Light Steel Joists: Strength and Durability for Every Build
Steel floor joists are lightweight yet incredibly strong, offering long-term stability as an essential element of any metal house frame. Their robust design makes them one of the most cost-effective building solutions available.
Phu Nguyen Steel Frame manufactures light gauge steel (LGS) floor joists in customizable sizes for a variety of projects. Our steel joists range from 200mm to 600mm in depth and can span up to 8 meters.
To ensure strength, durability, and reliability, all our steel floor joists are double-screwed and university-tested for peace of mind. Through innovative techniques in floor setting and utilizing the inherent strength of steel joists, we can help reduce the need for heavy structural steel.
Steel framing floor joists offer greater design flexibility. Their high strength-to-weight ratio reduces the need for internal load-bearing walls and columns. The result is a smoother, more efficient flooring layout with a precise finish that other materials often struggle to match.

Why Choose Steel Floor Joists?
Steel floor joists have become a top choice among builders and clients in Victoria due to their numerous structural advantages over traditional timber. Here are some key reasons why steel floor joists stand out:
Durability – light gauge steel floor joists are highly resistant to deterioration. They will never rot, warp, shrink, or sag. Even better, they won’t attract or harbor termites, ensuring your home’s structure remains intact for decades.
Ease of Use – Steel floor joists are quick and easy to install. Delivered pre-fabricated and customized to your design, you’ll save significantly on labor costs and installation time, making them a highly cost-effective option.
Optimized for Outdoor Use – Our light gauge steel frames are coated with a zinc-aluminium-magnesium alloy, protecting the exposed steel edges from corrosion. Built to the highest industry standards, this coating is one of the main reasons our steel house frames are ideal for long-lasting, low-maintenance homes.
Flexibility – With steel floor joists, you’ll never need to compromise on design for practicality. The increased span of steel framing reduces the need for numerous load-bearing columns, offering more design freedom and creating a smoother, more flexible floor layout.
