Steel Structure Terminal

Steel Structure Airport Terminal is a prefabricated steel building system designed for passenger processing and transit facilities, including departure halls, arrival halls, check-in areas, waiting zones, baggage handling spaces, and airport extension projects.

This specification is for reference-the final implementation can be adjusted according to project-specific requirements.

Main Structural System

• H-section steel, square tube steel, channel steel, and angle steel manufactured from Q235B, Q345B, or Q355B steel grades, providing high load-bearing capacity and structural stability.
• Rigid frame, bent frame, and truss structural designs available for different span requirements and architectural layouts.
• High-strength bolt connection, welding, or combined connection methods selected according to project engineering requirements.

Secondary Structural System

• C-section and Z-section purlins support roof and wall systems while reducing structural dead load.
• Bracing systems and support members improve overall structural stiffness and resistance to lateral loads.

Roof & Wall Cladding System

• Color steel sheets or insulated sandwich panels available for roof and wall enclosures, supporting thermal insulation and weather protection requirements.
• Roof skylights, lighting strips, and high-side windows improve natural lighting performance.
• Roof ventilation skylights support indoor airflow management.

Fire & Corrosion Protection

• Hot-dip galvanizing, sandblasting, and shot blasting treatments improve corrosion resistance in different environments.
• Thin-layer or thick-layer fire-retardant coatings and fireproof boards enhance fire protection performance according to project requirements.

• Dimensions: customized length, width, height, span, single-span, or multi-span configurations.
• Structural design: rigid frame, truss structure, or bent frame layouts.
• Colors: customized roof, wall, and structural color selections.
• Insulation thickness: different sandwich panel thickness options based on thermal performance requirements.
• Roof types: single-slope, double-slope, curved roof, and daylighting roof systems.
• Doors: rolling doors, sliding doors, and swing doors.
• Windows: fixed windows, casement windows, sliding windows, and louver windows.
• Load requirements: customized wind loads, snow loads, and seismic design grades according to local standards.
• Surface treatment: hot-dip galvanizing, painting systems, sandblasting, or shot blasting treatments.

Custom solutions are developed according to project requirements and local building regulations.

Steel Structure Building vs Concrete Building

• Raw material inspection: verification of steel grade, chemical composition, mechanical properties, and mill certificates according to applicable standards.
• Dimensional inspection: checking cutting accuracy, member dimensions, hole locations, and fabrication tolerances.
• Welding inspection: implementation of visual inspection (VT), ultrasonic testing (UT), and magnetic particle testing (MT) where required.
• Surface treatment inspection: measurement of coating thickness, galvanizing thickness, and surface adhesion performance.
• Assembly inspection: trial fitting and inspection of bolt hole alignment and connection accuracy.
• Load and structural verification: review of design calculations according to local building codes and engineering standards.
• Third-party inspection support: SGS inspection services available upon request.
• Quality management systems: production performed under ISO 9001 quality management procedures, with materials and testing following applicable ASTM and CE requirements where specified.

• Steel members are bundled according to component type and secured with steel straps and identification labels for site installation reference.
• Small accessories, bolts, and connection parts are packed in numbered cartons or sealed boxes with packing lists.
• Roof and wall panels are separated using protective materials to reduce friction damage during transportation.
• Container loading plans are arranged according to component dimensions to improve loading efficiency and reduce empty container space.
• 40HQ, 40GP, or bulk cargo transportation can be arranged according to shipment volume and member size.
• Typical production lead time: approximately 25–45 days after drawing confirmation and deposit receipt, depending on project scale and customization complexity.
• Shipping documents can include packing list, commercial invoice, bill of lading, material certificates, and inspection reports if required.
