The two points that need to be considered in choosing a lightweight steel roof truss


steel-roof-truss-design-guideLightweight steel roof truss is one of the substitute ingredients of conventional steel roof truss and timber roof truss which have long been used in building structures. Associated with many brands and types of mild steel available on the market, consumers or potential users are often confused in choosing a lightweight steel roof truss. Some of the questions that usually arise are as follows:

1. The type and brand of mild steel that should be used
2. How to install a lightweight steel roof truss in proper way

Through this article, we want to give some tips and information about the choosing of lightweight steel roof truss. To get a quality lightweight steel roof truss, you need to pay attention to some points as follows:

1. Quality of the Steel

2. Anti-Corrosion Coatings

Further explanations regarding the above can be seen as follows:

1. Quality of The Steel

The lightweight steel roof truss has very thin profile, usually ranging from 0.4 to 1 mm. Steel materials are normally considered based of “High Tension Steel”, denoted by the codes. An example is the G550, which means having Yield Strength and Tension Strength of about 500 Mpa. It is difficult to determine the quality of the materials available on the market, but by knowing the steel code, we can obtain a written assurance that the raw materials we use have the power of the values symbolized by the steel codes.

2. Anti-Corrosion Coatings
Layer Z (Zinc), often called Galvanized and AZ (Aluminum and Zinc) are the types of anti-rust coating that are most commonly used as protection against rust.

Each layer type has its advantage and disadvantage. Advantage of Aluminum Zinc (AZ) is more resistant to corrosion caused by salt water, while weakness is not resistant to mortar (corrosive). On the other hand, Zinc (Galvanized) is not corroded by mortar but less resistant to salt water.
