Light Gauge Steel Truss and Frames with AZ150 Zincalume 0.95BMT 168mm
follow AS1397 G550 Grade
Aluzinc, Zincalume and Galvalume are different trade names of one product. Aluzinc is cold rolled galvanized steel with metal coating composed of Aluminium (55%), Zinc (43.4%) and Silicon (1.6%). It is formable, weldable and readily accepts paint finishes.
Applications:
- Wall Framing
- Floor Joists
- Roof Trusses
Light gauge steel is a straighter, lighter, termite proof & fire-resistant way of construction as compared to traditional timber frames. We proudly utilise high quality steel that is compliant to Australian Standards.
Top Benefits of Light Gauge Steel Trusses
Light gauge steel trusses, also known as cold-formed steel trusses, are made from high-quality sheet steel fashioned into different shapes by roll forming. And they’re not just a pretty face in the construction industry; light gauge steel trusses have emerged as a game-changer, revolutionizing how structures are built. Offering many benefits, these trusses have become a preferred choice for architects, engineers, and builders.
- Strength and Durability
- Versatility in Design
- Ease of Installation
- Environmental Sustainability
- Cost-Efficiency
- Consistent Quality and Performance
Light Gauge Steel Trusses and Frames with AZ150 Zincalume 0.95BMT 168mm - Follow AS1397 G550 Grade
Light gauge steel trusses and frames are commonly used in construction for their strength, durability, and ease of installation. When manufactured using AZ150 Zincalume, these components offer additional benefits in terms of corrosion resistance, making them suitable for a variety of building applications, especially in areas with challenging environmental conditions. Below is an explanation of the key aspects of AZ150 Zincalume 0.95BMT 168mm light gauge steel trusses and frames, with reference to the AS1397 G550 Grade standard.
1. AZ150 Zincalume Coating
-
Composition: The AZ150 designation refers to the aluminum-zinc alloy coating, where the steel is coated with 55% aluminum and 43.5% zinc, with a small amount of silicon. This alloy provides superior corrosion resistance compared to traditional galvanized coatings.
-
Corrosion Resistance: The AZ150 coating offers three times better corrosion resistance than standard galvanized steel. This makes it highly suitable for outdoor and coastal environments, where steel is exposed to moisture, salt, and other corrosive elements.
-
Durability: AZ150 Zincalume steel is known for its long-lasting protection. The aluminum in the coating forms a protective layer of oxide on the surface, which further enhances the material's resistance to corrosion and environmental damage.
2. 0.95BMT (Base Metal Thickness)
-
Thickness: The 0.95BMT refers to the base metal thickness of the steel used for the trusses and frames. 0.95mm is a standard thickness for light gauge steel components, providing a balance between strength and weight.
-
Performance: With this thickness, the steel is strong enough to support structural loads but lightweight enough for easy handling and installation. The thickness also ensures good load-bearing capacity while maintaining cost-effectiveness.
3. 168mm Truss/Frame Depth
-
Structural Design: The 168mm refers to the depth of the steel trusses or frames. This depth is typically chosen to provide the necessary structural integrity and resistance to bending while still being lightweight and easy to handle.
-
Application: Steel trusses and frames with this depth are commonly used in residential and commercial construction, providing stability and resilience for roofs, ceilings, and floors.
4. AS1397 G550 Grade
-
AS1397 Standard: This standard specifies the requirements for cold-rolled and coated steel sheet and strip for building and general applications in Australia. AS1397 is widely used to ensure that the material complies with Australian building standards, ensuring the quality and reliability of the products.
-
G550 Grade: The G550 refers to the grade of galvanized steel and indicates a minimum yield strength of 550 MPa. For Zincalume steel, this grade ensures high strength and formability. It is particularly important for light gauge steel framing, as it ensures that the material will be strong enough to support the loads it is subjected to while being lightweight enough for ease of use.
-
Benefits of G550 Grade:
-
High tensile strength: Ensures better resistance to deformation and bending.
-
Better performance under load: Suitable for framing and trusses, where material strength is critical for structural stability.
-
Enhanced durability: Offers long-term performance in a variety of environmental conditions, including both urban and coastal areas.
5. Applications and Benefits
-
Residential and Commercial Buildings: Light gauge steel trusses and frames are widely used in the construction of residential houses, commercial buildings, and industrial structures. The AZ150 Zincalume coating helps to protect the steel components from rust and degradation, making them ideal for areas with high moisture or salt exposure.
-
Energy Efficiency: The reflective properties of Zincalume coatings help with heat regulation. The thermal reflectivity of the material helps to keep the interior temperature stable, contributing to the energy efficiency of buildings.
-
Ease of Construction: The use of light gauge steel reduces overall construction time. Pre-fabricated trusses and frames made from AZ150 Zincalume steel are lightweight and easy to transport, handle, and install, resulting in reduced labor costs and faster project completion times.
Conclusion
The combination of AZ150 Zincalume coating, 0.95BMT thickness, 168mm depth, and AS1397 G550 grade ensures that light gauge steel trusses and frames are a robust, corrosion-resistant, and cost-effective solution for modern construction. These materials provide long-term durability, superior strength, and ease of installation, making them an ideal choice for a wide range of applications in both residential and commercial building projects.
