In modern days, lightweight steel truss is gaining its popularity by providing optimum strength yet at the same keeping cost at minimum. Being regarded as ‘light’ yet not jeopardising the key requirement of roof structure (strength), is mainly contributed by its high tensile strength characteristic in comparison to timber trusses. Other benefits of lightweight truss are such as ; their usage promotes eco-friendly construction practices due to steel products are recyclable, rust resistant, termite proof and fire resistance for made of incombustible material.

Despite the many benefits of lightweight steel truss, there are still bungalows built with timber trusses especially architecture expectation for exposing the ‘natural feel’ of timber trusses.
