Modern Prefabricated Steel Building

The Modern Prefabricated Steel Building is designed for easy assembly and recyclability, making it ideal for industrial warehouses, office spaces, and residential use. This structure utilizes steel to form a robust load-bearing framework, often referred to as the main frame, which consists of beams and columns.

The bracing system includes:

• Tie bars
• Knee bracing
• Staying bars
• Column bracing
• Horizontal bracing

Together with the roof system, wall system, and floor system, these components create a complete metal structure that ensures exceptional stability and durability.

Compared with traditional concrete buildings, metal workshop buildings use steel plates or sectional steel instead of reinforced concrete, providing higher strength and superior seismic resistance.

Since most components are prefabricated in factories and assembled on-site, the construction period is significantly shortened.

Moreover, steel is reusable and recyclable, which reduces construction waste and makes metal workshops a more eco-friendly choice.

• 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.
• Cost-effectiveness: Its lightweight nature reduces foundation expenses, while rapid construction allows for earlier operation. Overall economic benefits surpass those of traditional concrete buildings.
• 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.
• 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.

• 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.
• 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.

• Shorter construction period: Prefabricated components require minimal on-site welding, making steel structure construction significantly faster than concrete builds.
• More eco-friendly: Steel components are hoisted and spliced without water, reducing dust and pollution in surrounding areas.
• Better cost performance: Faster construction cuts labor costs, with total expenses roughly 20-30% lower than traditional concrete buildings. Steel also offers greater durability.
• Lighter structure: Lightweight metal walls and roofs—far lighter than brick-concrete alternatives—reduce overall weight, easing foundation loads.
