If you’re planning a construction project in Australia, you might be wondering about the costs of light gauge steel (LGS) framing — an increasingly popular alternative to traditional timber framing. But what exactly drives the cost per linear metre of LGS? It’s not just about the material itself; a variety of factors, from the thickness of the steel to the complexity of the design, can make a significant difference in the overall price. In this article, we’ll break down the key elements that influence LGS framing costs, using real-world examples and offering insights specific to the Australian market.
What Is Light Gauge Steel (LGS) Framing?
Light-gauge steel framing (LGS) is a modern, lightweight alternative to traditional timber used in both residential and commercial construction projects across Australia. Often called “cold-formed steel,” LGS is manufactured by shaping thin sheets of steel into structural components, which are then used for framing walls, floors, and roofs. It’s a preferred option for many Australian builders due to its durability, versatility, and resistance to environmental challenges like termites and bushfires.
The use of LGS has significantly grown in the past decade, particularly in states like South Australia and Queensland, where adoption rates can range from 25% to 30%. This rise is driven by several factors — from the increased need for faster construction timelines to its ability to withstand Australia’s unpredictable climate. In fact, in metropolitan areas such as Melbourne, LGS is seen as a staple in both commercial and residential projects.
But what exactly influences the cost of LGS framing? The price isn’t set in stone; it fluctuates depending on various factors, which we’ll explore below.

How Location Impacts LGS Framing Costs?
The cost of transporting and delivering light gauge steel framing can vary greatly based on location. For example, in remote areas or regions with limited access, transport fees can increase substantially. In metropolitan areas like Melbourne, freight costs may range between $50 and $100 per tonne. However, for more isolated locations, costs can skyrocket to $300 per tonne. This is especially true for areas that are difficult to reach or require special handling to ensure the materials arrive safely.
If you’re building in a remote area or on a difficult site, it’s essential to factor in these potential transportation costs when planning your LGS framing budget. In many cases, it may be possible to negotiate better rates with suppliers who can consolidate deliveries or choose more cost-effective transport routes.
Factors Behind The Light Gauge Steel Framing Cost Per Linear Metre
Steel Grade And Gauge: The Foundation Of Cost
The gauge, or thickness, of the steel plays a significant role in determining the price of light gauge steel framing. Generally, the thicker the steel, the more expensive it will be. For load-bearing walls, builders typically use 16- or 18-gauge studs, while interior walls often require thinner 20- or 25-gauge studs. The heavier gauge steel offers more strength but comes at a higher cost, impacting your framing budget.
Material Quality And Specification
The quality of steel used in light-gauge steel framing can significantly impact costs. Higher-quality steel is generally more expensive but offers superior durability, strength, and long-term performance. Choosing high-grade materials ensures the structural integrity of the build and helps maintain compliance with Australian building standards, which can influence both material costs and project timelines.
Labour Costs: The Hidden Variable
Labour is a substantial portion of the overall cost. In Australia, steel framers typically charge between $55 and $75 per hour, depending on the project’s complexity and site access. For larger or more complex projects, these costs can rise due to increased engineering, fabrication, and installation time. As much as 25% to 45% of the total framing cost can come from labour.
Supply Vs. Supply-And-Install Contracts
A supply-only contract covers the materials and delivery to the site, while a supply-and-install contract includes the cost of on-site assembly and installation. Opting for a supply-and-install contract adds around $20–$40 per m² to the overall cost but removes the hassle of managing the erection process yourself.
How To Reduce The Cost Of Light-Gauge Steel Framing For Your Project?
Strategies To Minimise Light Gauge Steel Framing Costs
While the cost of light-gauge steel framing can be higher than timber, there are several strategies you can employ to reduce the overall expense. Here are some practical ways to cut down on your steel framing costs:
- Plan Ahead and Choose the Right Design
Simplifying the design and layout of your project can help reduce both material and labour costs. For instance, opting for standardised frame sizes, rather than custom designs, can help reduce waste and fabrication time. - Invest in Prefabrication
Prefabricated steel frames can reduce on-site labour costs by up to 50%. By having parts manufactured and pre-assembled off-site, the time spent on site is significantly reduced, thereby reducing labour costs. - Use Local Suppliers
Transport costs can add up quickly, especially for projects located in remote or hard-to-reach areas. Working with local suppliers who are geographically closer can reduce freight and transport costs significantly. - Leverage Bulk Purchasing
If you’re working on a large-scale project, buying materials in bulk can provide significant savings. Many suppliers offer discounts for bulk orders, so consolidating your orders can help reduce the per-metre cost.
Why Design And Structural Requirements Matter?
The design complexity and structural requirements of your project will directly impact both material and labour costs. For example, multi-storey buildings or irregularly shaped homes often require more materials, engineering, and fabrication time. These factors can raise the cost of your framing, so understanding the requirements upfront and adjusting your design accordingly can help keep expenses in check.
