![]() While steel framing does not absorb water, even galvanised framing can rust if it is exposed to moisture for extended periods. Steel can be used in all climate conditions and is durable and long-lasting if kept dry. It is vermin and insect proof but vermin can live in spaces between light steel framing. Steel won't burn, but will deform under high heat. Because of its strength and flexibility, steel framing is excellent at resisting earthquakes. They are often delivered pre-fabricated to site, and clearly identified for assembly. ![]() ![]() Steel frames are easy to handle and can be erected quickly. LSF construction may be suitable for steeply sloping sites where heavyweight construction could require excavation and extensive foundations. LSF construction is comparable in price to timber construction. Steel is strong both in tension and compression. LSF construction can either be used as a complete construction system, including exterior walls and roof framing, or it can be used for interior partitions only. Steel beams can support long spans (eg for large windows or openings), and are often used in combination with other structural systems, like timber or LSF construction for this purpose. Heavy steel construction involves a structural skeleton of large steel members. There are two main types of steel construction – heavy and light steel frame (LSF) construction.
