Advantages of Steel Structure Building:
1. Easy to assemble
Prefabricated steel components are installed on-site as per drawings:
first steel columns with cross-bracing, followed by roof beams and horizontal bracing, and finally purlins and enclosures. 2.Cost-effectiveness
Its lightweight nature reduces foundation expenses, while rapid construction allows for earlier operation.
Overall economic benefits surpass those of traditional concrete buildings.
3. Simplified construction with short timelines
Factory-manufactured components are assembled on-site, drastically shortening build time. A 4,000㎡ steel structure building can be installed in approximately 40 days.
4. Energy-efficient & eco-friendly
Corrugated color steel sheets and sandwich panels boast energy-saving properties. Dry construction avoids dust and pollution from concrete work, and steel’s recyclability further reduces environmental impact.
Design Key Factors:
1. Optimal column spacing
Using H-section steel columns and beams, column spacing
directly influences steel usage and costs. Typically set at 6.8–9m for economic efficiency (adjustable for specific needs).
Building height should align with functional requirements (e.g., equipment, human activity) and maintenance access.
2. Proper lighting & ventilation
Large-span, open interiors demand human-centric, energy-saving designs. For tall buildings, ground-floor operable windows serve as primary air inlets, paired with roof ventilators to efficiently address lighting and ventilation needs.
Differences vs. Concrete Buildings:
1. Shorter construction period
Prefabricated components require minimal on-site welding, making steel structure construction significantly faster than concrete builds.
2. More eco-friendly
Steel components are hoisted and spliced without water, reducing dust and pollution in surrounding areas.
3. Better cost performance
Faster construction cuts labor costs, with total expenses roughly 20–30% lower than traditional concrete buildings. Steel also offers greater durability.
4. Lighter structure
Lightweight metal walls and roofs—far lighter than brick-concrete alternatives—reduce overall weight, easing
foundation loads.
