Steel Structure Equipment Hangar for Australian Agricultural Machinery Depot
Case Detail
Partner Country: Australia (New South Wales)
Cooperation Timeline: 2025
Client Profile: A leading agricultural machinery operation in New South Wales, specializing in large-scale crop cultivation and livestock management, with a fleet of over 50 tractors, harvesters, and agricultural implements.
Project Demand: To construct a specialized steel structure facility for long-term storage, maintenance, and shelter of heavy agricultural machinery, addressing the region's frequent high-intensity winds and ensuring year-round equipment protection.
Project Execution
1. Design & Planning
- Architectural Parameters: Total area of 1,800 ㎡ (30 m × 60 m), eave height of 7 m, ridge height of 9 m; gable roof with a 10° slope for efficient rainwater drainage.
- Structural Design: Adopted a portal frame steel structure with Q355B high-strength steel for main columns and beams, ensuring superior load-bearing capacity and wind resistance. The design complies with Australian Standards AS 4100 and AS 1170, with a design wind load of 0.75 kN/㎡, capable of withstanding gusts up to 70 m/s (Category 2 wind zone).
- Functional Layout: Equipped with 4 sets of 5 m × 6 m overhead roller doors for easy access by large machinery, 2 maintenance workstations with 3-ton overhead cranes, and a dedicated tool storage area; the floor is reinforced with 20 cm thick C30 concrete to support heavy equipment weight.
2. Material Usage
The project utilized a total of 82 tons of structural steel (main frame: 52 tons, purlins & wall girts: 22 tons, bracing systems: 8 tons), with a steel content of approximately 45.5 kg/㎡, falling within the high-load steel structure range of 40–50 kg/㎡ for large-span agricultural facilities.
- Main Frame: Hot-rolled H-beams (H300×150×6.5×9.0 and H350×175×7×11) for columns and roof beams, ensuring stable load distribution.
- Enclosure System: 0.5 mm thick galvanized color steel plates for roof and walls, with 100 mm thick rock wool insulation core for thermal insulation and sound absorption, meeting Australian fire protection Grade B1 standards.
- Foundation & Accessories: 120 m³ of C35 reinforced concrete for independent foundations, 48 sets of high-strength anchor bolts (M36 × 800 mm) for frame fixation, and 6 sets of 5-ton overhead cranes with electric hoists.
3. Construction & Completion
- Construction Period: 45 days (from site preparation to acceptance), with 20 on-site construction personnel and 3 professional supervisors.
- Key Construction Highlights:
- Precision foundation construction: Excavated to a depth of 1.5 m, with steel reinforcement cages tied and concrete poured in one go to prevent settlement.
- Steel frame assembly: Adopted high-strength bolt connection + welding dual fixation, with welding seams inspected via ultrasonic testing to ensure 100% qualification.
- Enclosure installation: Strictly controlled purlin spacing at ≤1.2 m to meet wind resistance requirements, with color steel plates fixed using hidden rivets and anti-leakage sealant applied at all joints.
- Acceptance Standards: Passed Australia's local wind load, load-bearing, and fire protection inspections; all equipment stored in the hangar has remained intact through 3 consecutive spring windstorms (gusts 60–65 m/s) since completion.
Project Advantages
- Superior Wind Resistance: The integrated portal frame structure with diagonal bracing and reinforced foundation anchoring effectively resists regional high winds, eliminating risks of roof uplift or structural deformation.
- Durability & Low Maintenance: Galvanized steel components and anti-corrosion coating reduce rust and wear, with an expected service life of over 30 years, cutting annual maintenance costs by approximately 28% compared to traditional concrete structures.
- High Space Utilization: Column-free interior design maximizes usable space, accommodating up to 60 large agricultural machines simultaneously and improving operational efficiency for machinery maintenance and deployment.
- Compliance & Safety: Meets Australian agricultural machinery storage standards, with fire insulation, emergency exits, and equipment lifting systems ensuring safe operation.
Client Feedback
The client praised the project for its "on-schedule delivery, compliance with local wind resistance standards, and significant improvement in equipment management efficiency." The facility has become a core part of their agricultural operation, providing reliable protection for machinery and supporting stable production during extreme weather seasons.
Cooperation Value
This project demonstrates our capability to deliver customized steel structure solutions for global agricultural projects, integrating international design standards, precise material control, and on-site construction management. It has laid a solid foundation for long-term cooperation in Australia's agricultural infrastructure sector.
