Aluzinc Zincalume and Galvalume 0.95BMT 168mm used for Light Gauge Steel Truss and Frames
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 .
Aluzinc is used in applications where long life is an essential requirement. Aluzinc coated steel has superior long term corrosion resistance in most atmospheric conditions. This is achieved through the combination of the sacrificial protection of the zinc and the barrier protection of the aluminum. Corrosion rates vary according to the severity of atmospheric conditions. Aluzinc steel coatings out-perform galvanized coatings from 2 – 6 times. The protective mechanism for Alu-zinc and hot-dip-galvanized steel are such that the hot-dip-galvanized coating initially protects better but the zinc coat will gradually corrode away more and more in the vicinity of the edge and the protective effect will be lost. Then the aluminum part of the Aluzinc coating will persist for a longer period of time, and the protection will thereby remain
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.
Light gauge steel trusses are engineered to be incredibly strong and durable. Constructed from high-quality steel, they possess remarkable load-bearing capabilities, ensuring the structural integrity of buildings even in the face of extreme weather conditions and natural disasters. Unlike traditional timber trusses, steel trusses are resistant to warping, rotting, termites, and other pests, thereby prolonging the lifespan of the structure.
Versatility in Design
One of the most significant advantages of light gauge steel trusses lies in their versatility in design. These trusses can be customized to fit the unique specifications of any project, allowing architects and designers to explore innovative and intricate designs with ease. Whether it’s for residential, commercial, or industrial applications, steel trusses offer the flexibility to create open and spacious interiors spanning large distances without the need for cumbersome support columns.
Light gauge steel trusses offer a faster and more streamlined installation process than traditional building materials. Precision-engineered off-site, these trusses arrive at the construction site ready for assembly, reducing construction time and labor costs significantly.
Over 75 percent of construction waste, including wood, drywall, plastics, asphalt shingles, and bricks, ends up in landfills. In an era when sustainability is paramount, light gauge steel trusses shine as an eco-friendly building solution. Steel is one of the most recycled materials on the planet, with the ability to be repurposed repeatedly without compromising its structural integrity. By opting for steel trusses, builders contribute to the conservation of natural resources and reduce the carbon footprint of their projects.
While steel trusses may be more expensive than their timber alternatives, their long-term cost-efficiency cannot be overlooked. The actual cost of steel depends on the weight of the component. In many cases, a CFS truss system can be designed to be lighter overall using less material than wood trusses. Construction cost is minimized by faster and easier installation, less material waste, and reduced delivery costs. With minimal maintenance requirements and superior durability, steel trusses offer substantial savings over the lifespan of the structure.
Light gauge steel trusses are manufactured to stringent quality standards, ensuring consistency and reliability in performance. Unlike timber, which is susceptible to moisture content and quality variations, steel trusses maintain their structural integrity without the risk of warping, shrinking, or twisting over time. This reliability translates into peace of mind for builders and occupants alike, knowing that their structure is built to last.
