Steel and concrete structures are the two main choices in the construction of modern shophouses. Many boarding house and shophouse contractor, home building services, to commercial fit out services using both depending on design needs and budget.
As a building owner or investor looking to build or renovate a shophouse, understanding the cost comparison between steel and concrete structures is crucial to ensuring the end result remains strong, aesthetically pleasing, and efficient.
Building a shophouse isn't just about erecting walls and a roof. The process involves careful consideration of structural strength, construction time, and cost efficiency.
Many owners work with contractors or specialized facility contractors to achieve the best results, especially in commercial-scale projects such as two-story shophouses, shophouses, or multi-purpose business buildings.
Understanding Steel Structures and Concrete Structures
Before discussing cost comparisons, we need to understand what steel structures and concrete structures are.
Steel structures use metal materials such as WF steel, H-Beam, or C-channel as the main frame of the building.
This material is renowned for its high strength, good elasticity, and relatively quick installation process. Many home architects and office contractors favor steel for its precision and practicality.
Meanwhile, the concrete structure consists of a mixture of cement, sand, gravel, and water formed with iron reinforcement.
Concrete is often used because of its ability to withstand heavy loads and its resistance to extreme weather.
In large building projects, home contractors and home renovation services still use concrete as the main standard because of its durability.
Both are equally strong, but have different characteristics and processing costs.
Advantages of Steel Structures for Shophouse Buildings
Steel structures are often chosen by modern boarding house and shophouse contractors because they have a number of competitive advantages.
Faster Processing Time
Steel frames are precisely manufactured in the factory, requiring only on-site assembly. This process saves construction time by 30–40 minutes compared to cast concrete. For business owners who want to quickly operate their shophouses, steel structures are an efficient option.
Lighter Weight and Stronger
Despite its light weight, steel has a very high tensile strength. This makes buildings more resistant to earthquakes and vibrations, making them suitable for densely populated areas such as commercial areas.
Flexible for Design and Renovation
Steel is easily reshaped, so when planning to add rooms, expand an area, or renovate, the structure can be adjusted without a complete overhaul. This makes it easier for home improvement or kitchen remodeling services to expand the space.
Minimal Construction Waste
Steel-based projects generate minimal material waste because all components are pre-measured in the factory. This makes them environmentally friendly and cost-effective in terms of material waste.
Advantages of Concrete Structures for Shophouse Buildings
Even though the work takes longer, concrete still has its own advantages that make it a favorite of home contractors and contract contractors.
Excellent Compressive Strength
Concrete excels at withstanding large vertical loads, making it ideal for multi-story buildings. Two- to three-story shophouses typically use concrete structures for long-term safety.
Easier Maintenance
Unlike steel, which requires periodic anti-rust painting, concrete requires no special maintenance. This results in lower operating costs in the long run.
Soundproof and Comfortable
Thicker concrete walls and floors help reduce external noise. This is crucial for shophouses that also serve as living quarters on the upper floors.
Fire and Weather Resistant
Concrete is non-combustible and unaffected by extreme temperature changes. This is an important consideration for commercial buildings that are at high risk of high temperatures or sparks.
Disadvantages of Steel Structures
Despite its advantages in terms of speed and flexibility, steel structures have several disadvantages that need to be considered.
a. More expensive material prices
Steel costs more per kilogram than concrete. While time-efficient, as a pure material, steel requires a larger initial investment.
b. Needs Routine Maintenance
Steel is prone to rust if not properly coated. Over the long term, custom facility contractors typically recommend repainting every 3–5 years to maintain the structure's durability.
c. Less heat resistant
Under extreme temperature conditions, steel can expand, requiring additional protective systems such as heat insulation.
Disadvantages of Concrete Structures
Likewise with concrete, there are several aspects that need to be considered before choosing it.
Longer Construction Process
Concrete requires several weeks of curing time, making the project take longer than steel.
Heavy Weight
Concrete has a high specific gravity, so it requires a stronger foundation and additional costs in underground structures.
Difficult to Modify
If one day you want to add a room or expand a space, the concrete structure is difficult to change without dismantling most of the building elements.
Steel vs. Concrete Structure Cost Comparison
Cost is a primary consideration when choosing a building structure. Below is a descriptive explanation of the cost range without a table for easier understanding.
For steel structures, the price per square meter can range from Rp 3.5 million to Rp 5 million, depending on the type of steel (WF or H-Beam), thickness, and design. Lightweight steel structures for single-story shophouses may be cheaper, but if the design is complex and tall, the cost will increase.
Meanwhile, for concrete structures, the cost ranges from around IDR 3 million to IDR 4 million per square meter depending on the material mix, cement quality, and labor costs.
Although it may seem cheaper at first glance, the long construction time and the need for additional foundations can bring the total cost closer to that of steel.
If your project is carried out by a contract contractor, the price can be slightly more economical because it includes materials and labor.
However, for projects with modern commercial designs such as offices, cafes, or boutiques, many contractors choose steel structures because they speed up work time and the results are neater.
Building Durability and Lifespan
The durability between steel and concrete structures can be said to be balanced, as long as the maintenance is proper.
Steel structures can last more than 50 years if coated with anti-rust agents and regularly maintained. Concrete can also last up to 60 years, but if it develops small cracks or moisture, its strength can decrease.
Home architects often recommend a combination of the two—for example, concrete foundations and floors, while steel columns and roofs are used. This approach balances strength and cost efficiency.
Design Aesthetics and Flexibility
Steel structures provide more space without numerous columns. They're ideal for modern shophouse designs that feature open interiors, such as shops, cafes, or offices.
Meanwhile, concrete gives a solid and elegant impression, ideal for shophouses with a classic or minimalist appearance with a flat roof.
Office contractors and commercial fit-out services often choose steel for interiors because of its ease of modification. When businesses need to expand or add new rooms, steel can be adapted without the need for major demolition.
Environmental Impact and Energy Efficiency
Steel structures are more environmentally friendly because the material can be recycled and produces less construction waste.
The construction process is also cleaner due to the minimal waste materials. Concrete, on the other hand, requires a lot of energy to produce cement, but offers the advantage of stable indoor temperatures.
If you want to build an environmentally friendly shophouse with an energy-saving concept, a steel structure is more recommended, especially when combined with heat insulation and natural lighting.
When to Choose Steel or Concrete Structures
Choosing between a steel or concrete structure depends on the building needs, project location, and budget.
Use a steel structure if you prioritize speed, flexibility, and a modern look. It's suitable for business projects such as cafes, offices, multi-story shophouses, or warehouses.
Choose a concrete structure if you prioritize quietness, soundproofing, and resistance to fire and extreme weather. It's suitable for shophouses that also function as residences.
Tips from a Professional Contractor
Experienced contractors will usually provide the best combination of both materials.
As an example:
- Concrete foundation for basic strength.
- Steel columns for speed and flexibility.
- Concrete finishing for a sturdy and aesthetic impression.
If you work with a professional home building or home improvement service, they will help you prepare a RAB (Cost Budget Plan) to make the project more efficient without sacrificing quality.
Conclusion
Both steel and concrete structures have their own advantages and disadvantages.
Steel excels in terms of speed, flexibility, and long-term efficiency, while concrete excels in terms of durability, comfort, and relatively more affordable initial costs.
Choosing the best structure should be tailored to your needs, design, and long-term building plans. Don't just focus on price; consider its utility and long-term maintenance.
