7 Considerations When Choosing Steel Materials for Prefabricated Steel Buildings

Pre Engineered Steel Building - 17/06/2024

Prefabricated steel buildings are increasingly favored for their flexibility, rapid construction, and cost-effectiveness. However, ensuring quality and durability for the structure requires a careful selection of suitable steel materials. This article will outline the considerations to keep in mind when choosing steel materials for pre-engineered steel buildings, aiding in optimizing efficiency and cost savings.

1. Benefits of Selecting Appropriate Steel Materials for Prefabricated Steel Buildings

Steel materials are the ideal choice for constructing structures that require high stability, such as high-rise buildings, bridges, and important infrastructure projects, due to various benefits:

  • High Durability: Steel has an exceptional strength-to-weight ratio, allowing structures to withstand heavy loads without the need for numerous supports. Steel beams can span up to 60 meters, resist harsh environments, and are fire-resistant, ensuring safety.
  • Energy Efficiency: Insulated steel reduces heat transfer, saving 30-40% of energy. Designs allow for maximizing natural light, reducing the need for electric lighting.
  • Effective Construction: Pre-manufactured steel materials shorten construction period by 40-50%. High precision with a tolerance of ±2mm, flexibility in design, suitable for various projects.
  • Cost Savings: Steel is competitively priced, reducing labor and maintenance costs by up to 50% compared to reinforced concrete.
  • Environmentally Friendly: Steel can be 100% recycled, reducing construction waste. Construction generates less dust and noise, uses less water, minimizes waste, and protects natural resources.

2. Factors to Consider When Choosing Steel Materials for Prefabricated Steel Buildings

2.1. Durability

Regarding steel grades, when constructing prefabricated steel buildings, it is crucial to consider the appropriate grade of steel that meets the requirements for load-bearing, durability, and environmental conditions.

For Example: Q300, SS400 may be suitable for standard warehouses, while Q345, SS450 are preferable for warehouses with high loads.

For the thickness of steel , it is necessary to select the appropriate thickness that matches the span, beam spacing, load-bearing capacity, and safety requirements. Using steel with optimal thickness helps avoid excess or insufficient material.

Ensure that the selected steel type (ASTM, JIS, TCVN) meets the appropriate standards to ensure quality while maintaining cost-effectiveness.

2.2. Corrosion Resistance

Corrosion significantly impacts the lifespan, maintenance, and aesthetics of steel structures, especially in harsh environments. When designing, it is necessary to pay attention to corrosion prevention measures such as effective drainage systems and well-ventilated prefabricated steel building structures.

For environments with acids, salt, or high humidity, galvanized steel or epoxy paint should be chosen. For relatively normal environments, electrostatic painting can be considered as an alternative.

2.3. Fire Resistance

Risk of Fire and Explosion

Determine the risk of fire and explosion of the construction based on the type of activities, storage materials, and population density.

For example: Chemical storage warehouses or manufacturing plants have a higher risk of fire and explosion compared to offices or residential buildings.

Fire Resistance Requirements

Regulations on fire resistance requirements for construction items according to fire fighting and prevention standards.

Common fire resistance durations include 30 minutes, 60 minutes, 90 minutes, 120 minutes, 150 minutes, and 180 minutes.

For example: warehouses containing hazardous chemicals require longer fire resistance durations compared to residential buildings.

Construction Methods

Choose appropriate fire-resistant coating methods:

  • Spray painting method: Cost-effective, rapid construction.
  • Panel cladding method: High efficiency, good aesthetics.

When constructing prefabricated steel buildings, it is essential to select suitable methods based on the type of steel , component sizes, and construction conditions.

Quality Certifications

Before constructing prefabricated steel buildings, suppliers should provide quality certifications for fire-resistant steel and fire-resistant paint/coating. Additionally, other certifications such as quality assurance, durability, and material performance should be considered.

2.4. Cost Efficiency

Efficient Utilization Calculation

When constructing prefabricated steel buildings, it’s important to select appropriate sizes to avoid material waste due to excess cutting or shortages. Additionally, consider using recycled steel to save costs and contribute to environmental protection.

Choosing Construction Methods

Prefabricated steel building construction should employ rational construction methods that are suitable for actual conditions, saving time and labor.

Minimizing Material Waste

Apply construction measures to minimize waste and material damage during construction. At the same time, utilize the remaining steel scrap for other items. Throughout the prefabricated steel building construction process, it is necessary to monitor and control the procurement and construction costs of steel materials.

2.5. Structural Requirements

To ensure safety, durability, and efficiency of use for prefabricated steel buildings, it is important to consider the following structural requirements after selecting steel materials:

  • Load-bearing Capacity:

It is necessary to choose steel materials with appropriate strength to meet the loads of the structure, including dead loads (self-weight), live loads (machinery, equipment, goods), wind and rain loads, and dynamic loads.

  • Hardness and Stability:

The steel materials need to possess high hardness and stability to ensure that prefabricated steel structures remain stable, without sagging, warping, or vibrating under the action of the loads. Choosing steel with suitable thickness and size, combined with effective connection systems and reinforcement to ensure hardness and stability for the structure.

2.6. Sustainability and Environmental Impact

Choosing Green Steel Suppliers

Prioritize suppliers that implement environmentally friendly steel production processes, utilizing modern technology to save energy and minimize emissions.

It is necessary to pay attention to the application of effective wastewater and solid waste treatment measures, and to select suppliers with certifications for sustainable production, such as LEED or ISO 14001.

Optimized Design

In the design phase, emphasis should be placed on minimizing the necessary amount of materials, utilizing natural light, and passive ventilation to reduce energy consumption. Additionally, the selection of environmentally friendly insulation and waterproofing materials should also be considered.

2.7. Aesthetic Considerations

Prefabricated steel buildings must not only ensure quality and durability but also meet aesthetic requirements, harmonizing with the surrounding landscape and fitting the intended purpose. Below are important factors to consider:

Design and Color

  • Style: Choose a design that aligns with desired architectural styles (modern, classical).
  • Color: Utilize a variety of painted steel colors to create focal points for the structure.
  • Combination with other materials: Combine steel with materials like glass, wood, and stone to enhance aesthetics.

Surface Treatment of Steel

  • Galvanization: Provides a shiny surface, and excellent rust resistance.
  • Powder coating: Smooth surface, diverse colors, high durability.
  • Corten steel: Creates a unique natural rust effect.

Detailed Design

  • Pay attention to small details: Joints, welds, edges, etc.
  • Design lighting systems: Create highlights at night.
  • Use decorative elements: Logos, signage, etc.
