Light Steel Construction System

Light steel construction system - Light steel is carbon steel that is rigid and strong so that it is widely used for construction purposes. Light steel has ferromagnetism (magnetism) which means it can also be used as a car frame, making electrical equipment and firearms.

Light steel is high quality steel that is light and thin, but its strength is not inferior to conventional steel. There are several types of mild steel that are grouped based on the value of tensile strength (tensile strength). The ability of tensile stress is generally based on the final function of the mild steel.

For example for structural products such as lightweight steel roof truss using mild steel with high tensile stress (G550). However, for various home appliances products, light steel with lower tensile stress (G300, G250) is needed which is more flexible and soft so that it is more easily formed as desired.

Because of the level of quality and high tensile strength, it's no wonder mild steel is thinner and lighter than conventional steel. Baja G550 can be interpreted as steel that has a tensile strength of 550 Mpa (Mega Pascal). This quality test can only be proven in the laboratory.

Although it is lighter and thinner than conventional steel, with a tensile strength of 550 Mpa mild steel can be used as a mainstay to support the load structure of the building. For non-structural functions such as roof cover, use G300 quality lightweight steel.

What about the thickness of mild steel? In the general market the thickness ranges from 0.20 - 2.00 mm. This thickness variation is determined by function, how much the load is supported and the size of the steel span itself. Smaller thickness compared to conventional steel with the aim to reduce the structural load of the building.

Mild steel horses have a thickness between 0.45 - 1.00 mm. Unlike the columns that will support a larger load, the thickness ranges from 1.00 -2.00 mm (profile C). Whereas for metal tile the thickness is 0.20 mm because it can be said that it does not carry the load with that thickness is sufficient.

Steel is composed of iron and carbon (Fe and C). If the element mixes with water and the air will emerge a reaction that encourages rust. So light steel needs to be coated with stainless steel. The application of anti-rust coating is very important to keep the material durable and durable.

Advantages of Light Steel Construction

Light steel construction is a favorite choice for roof construction. This is inseparable from the various advantages of mild steel construction compared to other conventional constructions. Come on, find out what are the advantages of using light steel construction as a roof frame.

Light but has high strength

Light steel construction is a favorite choice as one type of building material because of its very light weight. This lightweight steel construction weight makes it easier for the transportation and installation process when building a house or building.

Has a light weight and the potential for a small dead load does not reduce the tensile strength it has. This makes lightweight steel construction suitable for roof design structures, especially wide enough construction.

Has no less power than conventional construction

Light steel construction is able to withstand large deformations without causing collapse in tensile loads both throughout the fabrication, transportation, and construction processes without causing damage.

In contrast to conventional steel material or wood material that is hard and brittle, which will be destroyed immediately when subjected to shock loads. Mild steel construction is capable of accepting flexibility, shock loads and shear loads so that the shape of the structure can be more flexible.

Light steel construction has a high form consistency

Because it is a factory-made product, light steel construction has consistency in terms of its quality and quality. This helps to create precise structures when building or carrying out home and building renovations.

Durable and porous

One of the advantages of lightweight steel construction is strong durability. You don't need to worry about termite attacks and get tired of finding ways to eradicate termites or worry about fragile porous material. In addition, the maintenance and maintenance of lightweight steel construction materials is also very easy and economical compared to other constructions.


Although made of metal, lightweight steel construction has resistance to rust. This makes light steel construction can still be reused or recycled when it is no longer used.

Saving time

Because of its light weight and also the precise and consistent shape, the installation or installation of lightweight steel construction is much shorter. This is coupled with the simple process of connecting mild steel construction with bolts, rivets, or welds so that the installation process is not too difficult.

Why You Should Choose a Light Steel Frame Instead of Wood

The use of lightweight steel frames from several developers who use this type of roof truss, many adapt this method from the Japanese cherry country. Using this lightweight steel roof truss, it is very suitable for use in areas that are in fact prone to earthquakes.

If you are part of the section that does not know about the advantages of this type of roof truss compared to wooden frames, then continue reading this article.

Here are 6 main reasons,

Light steel frames will not be eaten by termites. As we know, the quality of wood that is widely used and that is on the market today is wood with 3 lower quality or less good. Not much else, even very rarely provide or use good quality wood such as teak to build a building. Therefore, the selection of lightweight steel frames is an absolute thing if your frame wants to have a more durable age

Light steel will accelerate the duration or working time of a building. Mild steel that is ready to install will certainly save a lot of time working on various building projects that you are working on. Even a house with type 36 can be completed in about 1 week using a lightweight steel frame.

Light steel frame structure which is certainly lighter than if you use wood as your roof frame. Of course this can facilitate the workmanship and security of your workers more secure.

Low-cost lightweight steel frame. Mild steel is not easily weathered. Imagine how much money you can save with this mild steel feature, especially in terms of the cost of maintaining your building in the future. In addition, according to several existing survey results, type 42 houses built with the structure of light steel roofs and brick walls, the cost of production can be saved up to a range of just 31 million (including the cost of covering the roof and outside of course) Amazing isn't it ... :)

Light steel frame has a structure or material that can be adjusted to the geographical conditions of an area. Suppose your building is on the seafront or beach, then the lightweight steel frame you use will be coated with certain materials that will adjust to the contour of the coastal area (not easily corroded of course). Do you have this excess wood material? I don't think so

To protect the environment. As we know that forests in Indonesia are not as green as they used to be due to illegal logging. Therefore, by using a lightweight steel roof it is tantamount to taking care of our environment which has already been damaged, does not get worse.

Today's mild steel is widely used as a substitute for wood or conventional steel as a roof frame. The roof frame made from CRC (cold rolled coil) has a mass that is light but strong and sturdy as a building structure. Light steel has a high quality with tensile strength above 550 MPA.

Currently in the mild steel market it has various types with tensile forces ranging from 650 MPA to 920 MPA. Light steel is usually produced with a C profile, although there are other profiles such as L and and boxes. Profiles on mild steel serve to enhance compressive strength.

Disadvantages of Light Steel

Light Steel Construction System
Although mild steel has many advantages over other materials, there are some disadvantages of mild steel that need to be anticipated during the construction process:

Lightweight steel roof frames need careful calculations.

If there are parts that have miscalculations or greetings in the installation process, the other parts of the roof will be affected. Therefore, lightweight steel roof truss needs more careful workmanship than other materials. Work on a lightweight steel roof truss needs to be made working drawings first so that the roof can be built and function properly.

The lightweight steel roof frame is less beautiful when the roof structure is exposed.

Unlike wood frames that can be exposed for aesthetic purposes, lightweight steel roof truss does not have the beauty when exposed. Lightweight steel roof frames need to be covered with ceilings to increase the aesthetic value in the room.

The price of the material is still expensive.

Compared to wood material, lightweight steel roof truss is still relatively more expensive. But with the scarcity of wood and the awareness to use building materials that are more environmentally friendly, lightweight steel roof trusses are now relatively more affordable and more cost-effective, especially in the long term.

Technological innovations are constantly amazing us. This time we will review the results of technological developments in terms of construction systems, which can be used to meet all architectural needs and can be applied to various types of buildings. This is a series of lightweight steel frame construction.

A system that uses products with the latest technology standards so that development projects can be faster, cleaner, and the end result has better quality compared to conventionally constructed buildings.
