Types of Building Structures Most Often Used in Indonesian Projects

In every construction project, choosing the type of building structure is a crucial decision that affects the strength, cost efficiency, and lifespan of the building. In Indonesia—with its geographical conditions, tropical climate, and potential for earthquakes—building structures must be adjusted to the needs and conditions in the field. Here are some of the most common types of structures used in various construction projects in Indonesia.

1. Reinforced Concrete Structure
This structure is most often found in high-rise buildings, houses, and public infrastructure. Reinforced concrete combines the compressive strength of concrete with the tensile strength of steel (reinforced iron) to produce a sturdy and durable structure. Materials such as threaded concrete iron, wire mesh, and bondek are important parts of this system.

2. Steel Structure
Often used for warehouses, factories, bridges, and high-rise buildings. Steel structures, especially the WF and H-Beam types, have the advantage of high tensile strength and faster installation. Steel is also relatively flexible against earthquakes, making it popular in earthquake-prone areas such as Indonesia.

3. Wood Structure
Still used in rural areas or traditional architectural projects. Although this material is environmentally friendly and readily available, wooden structures are less resistant to fire and termites, and require regular maintenance. Therefore, its use is now increasingly limited.

4. Composite Structure
A combination of concrete and steel designed to take advantage of each material. This structure is commonly used in large projects such as malls, stadiums, and office buildings. The use of steel plates for floors with cast concrete is an example of an efficient composite structure.

5. Retaining Wall and Gabion Structure
For projects involving land contours or slopes, such as toll roads and water channels, supporting structures such as wire gabions, retaining walls, and sheet piles are used to prevent the soil from collapsing or moving.

Choose a Structure, Prepare Quality Materials
Whatever type of structure is used, the success of the project is determined by the quality of the material and the accuracy of its implementation. PT Intisumber Bajasakti is ready to provide reinforced concrete, WF, H-Beam, wire gabions, plates, wire mesh, and various other materials that meet SNI standards and project needs in the field.
