Structural Steel

Structural steel is a fundamental material used in the construction of buildings, bridges, and various other structures.

Structural steel is widely used because it can be made into a wide range of shapes and sizes, making it a versatile and flexible solution for a variety of construction needs.

One of the key benefits of using structural steel is its strength-to-weight ratio, it is stronger than other materials like wood and concrete, but it is also lighter, making it easier to transport and handle. This means that structural steel is ideal for use in high-rise buildings, where weight is a major concern.

Our large New South Wales factory has all the facilities and equipment to produce and supply structural steel for projects large and small across New South Wales.  Our team of experts have years of experience producing the highest quality structural steel that meets industry standards.
