What is the pre-engineered steel building? The optimal solution for your projects

Pre-engineered steel buildings are the most popular model in the construction market today because of their superior advantages such as ease of design, high durability, cost savings, etc. To learn more about the features and functions that pre-engineered steel buildings bring, let's find out with BMB Steel in the article below.

1. What's the Pre-engineered Steel Building?

Pre-engineered steel buildings or pre-engineered metal buildings are structures made from factory-manufactured steel components. These steel components include columns, beams, purlins, trusses, walls, and roofing, which are pre-fabricated according to technical drawings and then transported to the construction site for final assembly.
To construct a pre-engineered steel building that meets quality standards and aesthetic requirements, the process is divided into three main phases:

• Design Phase: Concept development and detailed technical drawing preparation
• Manufacturing Phase: Fabrication of steel components in the factory according to technical specifications
• Construction Phase: Transportation and systematic installation of components to complete the structure

The systematic approach ensures quality control at every stage, from initial design to final assembly, resulting in a durable and efficient pre-engineered steel building. Each phase is carefully executed to maintain structural integrity while meeting project specifications.

2. Applications of Pre Engineered Steel Buildings

Pre-engineered steel buildings are currently applied in numerous construction projects including residential buildings, living spaces, warehouses, workshops, kiosks, shopping centers, cinemas, supermarkets, training centers, conference centers, hotels, restaurants, offices, sports centers, parking facilities, and public buildings (schools, hospitals, churches, etc.). Pre-engineered buildings are widely used in daily life thanks to their convenience, low cost, and rapid construction time.

3. Advantages and Limitations of Pre-Engineered Steel Buildings

3.1 What are the advantages of pre-engineered steel buildings? 

Today, pre-engineered steel buildings are increasingly widely used due to several outstanding advantages:

• Cost and Labor Savings: The main materials used in pre-engineered buildings are steel, metal sheets, columns, beams, and purlins combined with other cost-effective materials, resulting in significant cost savings. Moreover, construction can proceed easily under various conditions, minimizing the impact of external environmental factors like weather, thus reducing labor costs.
• Rapid Construction Time: As mentioned above, pre-engineered steel buildings are manufactured and designed in the factory. When construction is needed, components are transported to the site and only require assembly, significantly reducing construction time. Furthermore, these structures are highly flexible - they can be easily dismantled when necessary, or upgraded and expanded in the future without excessive time and effort.
• High Versatility and Diverse Applications: Pre-engineered buildings can meet various needs, from residential homes and retail stores to office spaces and industrial facilities like factories or agricultural buildings. The quality and functionality are comparable to traditional reinforced concrete structures.
• Flexible Integration with Other Components: A key strength of pre-engineered steel buildings is their design flexibility. You can easily add features like staircases, mezzanine floors, partition walls, or roof fascias according to usage requirements. This ensures the structure can fulfill all necessary functions of a complete building.
• Adaptability to Various Terrains: Thanks to their lightweight nature and flexible design, pre-engineered buildings can be constructed on various terrains, including rough surfaces or weak soil conditions where traditional reinforced concrete structures would be challenging to build.

3.2 Limitations of Pre-Engineered Steel Buildings 

Along with these advantages, pre-engineered buildings have some manageable limitations:

• Lower Fire Resistance: At high temperatures of 500-600°C, steel can deform like plastic, weakening the structure and risking collapse. However, at BMB Steel, this issue is addressed by applying modern fire-resistant coatings to surfaces, ensuring safety for pre-engineered buildings.
• High Corrosion Susceptibility and Lower Moisture Resistance: One challenge of pre-engineered buildings is that steel frames can corrode and rust over time. To ensure long-term protection, steel frames are pre-cast and coated with protective paint, both preventing corrosion and enhancing the building's aesthetic appeal.

5. Type of pre-engineered steel buildings

Pre-engineered steel buildings are divided into many different types. However, the main types commonly found in designs in the Vietnamese market include 4 types:

• Pre-engineered civil building: The type designed for people's living. Built for small households to live in. With a quick, easy, low-cost design. So now pre-engineered civil steel buildings are very popular with households. The design of a civil pre-engineered building needs to be fully structured to ensure a solid and comfortable living area.
• Pre-engineered industrial buildings: Built with simple architecture. Create a large space with a simple cover texture. Designing pre-engineered industrial buildings simply mean designing for warehouses, workshops for industrial parks, etc.
• Pre-engineered commercial buildings: Similar to pre-engineered industrial buildings, Pre-engineered commercial buildings have a smaller scale to serve the needs of trading and business locations, etc.
• Pre-engineered military buildings: Designed with a simple structure, serving military needs, such as a training place, a place to store military items, etc.

10. Frequently Asked Questions About Pre-Engineered Steel Buildings

What is the difference between pre-engineered steel buildings and reinforced concrete buildings? 

Pre-engineered steel buildings and reinforced concrete buildings have distinct differences in structure and construction methods. Regarding load-bearing structures, reinforced concrete buildings are constructed directly on-site through formwork installation, steel reinforcement, and concrete pouring - a process requiring significant time and labor. In contrast, pre-engineered steel buildings have components manufactured in factories and transported to the site for assembly, optimizing time and resources.

What factors affect the construction cost of pre-engineered steel buildings? 

The construction cost of pre-engineered steel buildings is influenced by several important factors, with project scale and complexity playing decisive roles. As the scale expands, construction costs increase. With larger projects, not only does the construction area increase, but technical details such as ventilation systems, lighting, and insulation also require more investment. Additionally, supplementary elements like walkways, staircases, canopies, or crane beams contribute significantly to total costs.

Besides scale, the choice of technology and construction materials directly affects costs. Advanced technologies like corrosion-resistant materials, color retention, or heat-reflective materials will have higher prices than conventional materials. Depending on environmental conditions and intended use, selecting specialized materials like leak-proof sheets, screw-fixed sheets, or gutter sheets for high-rainfall areas will create cost variations. Each factor needs careful consideration to ensure optimization between investment costs and long-term usage effectiveness.

Should you build a pre-engineered steel building? 

Whether you should build a pre-engineered steel building depends on your needs and conditions. Despite some minor drawbacks, pre-engineered steel buildings remain an ideal choice thanks to outstanding advantages like cost savings, and quick and easy construction. This is a suitable solution for those wanting to own a comfortable, modern home that's quick to build, convenient, affordable, and appropriate for development contexts with limited land and high population density.
