In the world of modern construction, lightweight steel has become one of the materials increasingly used for roof frames, residential buildings, commercial buildings, and large-scale projects. This material is known for its light weight, efficient installation, and resistance to termites and weather changes. It is no surprise that lightweight steel has now become a popular alternative to conventional frame materials such as wood.
However, before choosing lightweight steel, it is important to understand that not all lightweight steel has the same characteristics. In the market, lightweight steel is generally available with two main types of coating, namely galvanized and galvalume. Both are used to protect steel from rust, but they have different compositions and protection characteristics.
Currently, most lightweight steel circulating in the market uses galvalume material. Even so, galvanized lightweight steel still has its own advantages, especially for construction needs that prioritize an elegant appearance and maximum protection against corrosion because it has higher strength when exposed to cement. After being drilled for bolts, the drilled holes will not corrode. One galvanized lightweight steel product that can be an option is FUMIRATRUSS from FUMIRA.
Understanding Lightweight Steel and Its Function in Construction
Lightweight steel is a steel material made with a lighter weight than conventional steel, while still having good strength to support certain structures. This material is widely used as a roof frame because it has a precise shape, is easy to install, and is more resistant to termite attacks than wood.
In roof construction, lightweight steel is usually used as trusses, battens, and C-channels. Because of its light weight, this material can help reduce the overall load on the building structure. In addition, lightweight steel is also known to be more dimensionally stable, so it does not easily bend, shrink, or change shape due to temperature and humidity changes.
The use of lightweight steel also supports a faster construction process. With precise dimensions and a practical installation system, construction work can be carried out more efficiently. This is why lightweight steel is increasingly chosen for residential houses, commercial buildings, public facilities, and industrial projects.
The Advantages of Galvanized Lightweight Steel Compared to Galvalume
In general, lightweight steel has a protective coating so that the base material does not rust easily. The two most commonly found types of coating are galvanized and galvalume.
Galvanized lightweight steel uses a zinc coating as its main protection. This zinc coating protects the steel from the oxidation process that can cause rust. Under certain conditions, zinc can also provide cathodic protection, which helps protect scratched or exposed steel areas. FUMIRA explains that zinc can act as cathodic protection on scratched or exposed areas when in contact with air.
Why Choose Galvanized Lightweight Steel?
Many people choose lightweight steel based only on price or availability in the market. In fact, the selection of lightweight steel should consider building needs, the installation environment, coating quality, and long-term durability.
Galvanized lightweight steel can be the right choice for those who need a material with a clean appearance, optimal rust protection, and good performance when close to cement-based materials. These characteristics make FUMIRA galvanized lightweight steel relevant for various modern construction needs.
Here are some of the main advantages of FUMIRA galvanized lightweight steel that you need to know.
1. Maximum Protection Against Corrosion
Corrosion is one of the main challenges for metal materials, especially in tropical countries like Indonesia, which have high humidity levels. If steel material does not have proper protection, rust can appear and reduce the material’s service life.
FUMIRA galvanized lightweight steel uses high-quality zinc coated steel material. On the FUMIRATRUSS page, FUMIRA states that FUMIRA lightweight steel is produced using high-quality zinc coated steel material with SNI 2053 certification as protection against rust and corrosion.
The zinc coating on galvanized steel functions as the main protection against direct contact between the steel and the external environment. When this coating works properly, the risk of rust can be reduced, making the material more durable. This protection is very important for roof frames that are often exposed to temperature changes, humidity, and surrounding environmental conditions.
In addition, zinc has cathodic protection characteristics. This means that when there are small scratches on the steel surface, zinc can help protect the exposed steel parts. FUMIRA also explains that the zinc coating on iron or steel naturally has sacrificial characteristics over time. With this mechanism, galvanized lightweight steel has additional protection that supports the material’s resistance to corrosion.
2. More Resistant to Cement
In the construction process, lightweight steel is often close to various building materials, including cement. Contact with cement can be an important concern because the chemical properties of certain building materials can affect the protective coating of steel.
One of the advantages of galvanized lightweight steel is its better resistance to cement compared to several other types of coating. This makes FUMIRA galvanized lightweight steel an attractive choice for projects involving many cement elements, mortar, or connection areas with cement-based building materials.
Resistance to cement helps maintain the quality of the lightweight steel surface so that it remains optimal during the construction process and after the building is in use. By choosing a material that is more suitable for field conditions, the risk of premature damage can be minimized.
3. Strong, Termite-Resistant, and Stable
In addition to its coating advantages, lightweight steel also has structural advantages. FUMIRA presents several advantages of FUMIRATRUSS, including being strong, tough, termite-resistant, precise and easy to shape, easy and fast to install, maintenance-free, crack-resistant and not easily rusted, earthquake-resistant and wind-resistant, as well as environmentally friendly.
Unlike wood, which is vulnerable to termites, lightweight steel is not a food source for these pests. This makes lightweight steel safer for long-term use, especially in areas with a high risk of termite attacks.
In addition, lightweight steel has a more stable shape. This material does not easily shrink, bend, or crack like some natural materials. This stability is very important to maintain the shape of the roof frame and support building safety.
4. Precise and Easy to Shape
In construction, material precision greatly affects the final result. FUMIRA galvanized lightweight steel is produced according to industrial standards, so its shape and dimensions are more consistent. Precise material helps make the assembly process easier and reduces potential errors during installation.
Lightweight steel is also easy to shape according to design needs. This provides flexibility for contractors, applicators, or parties responsible for construction work to adjust the material to the required frame shape.
However, the selection and installation of lightweight steel must still be carried out by competent personnel. Structural calculations, frame spacing, types of connections, and roof load requirements need to be considered so that the construction results are safe and optimal.
5. Supports an Efficient Construction Process
Lightweight steel is known as a material that supports construction efficiency. Its light weight makes transportation and handling on site easier. In addition, lightweight steel installation systems are generally faster than conventional materials.
This efficiency can help save project working time. For the construction of houses, shophouses, public facilities, and commercial projects, more efficient working time is certainly an added value. With the right material, work can proceed in a more planned manner and still produce quality results.
