Outdoor Aluminum Alloy Pavilion Project Case

I. Project background: Thailand coastal resort viewing pavilion group

The 24 corridor-style pavilions completed in June 2025 are made of 6063-T5 aluminum alloy profiles, facing the challenges of high salt fog marine environment. Project innovation realization:

Zero welding process: all use mortise and tenon bolt connection

Modular prefabrication: factory prefabrication rate reaches 95%

Corrosion-resistant design: surface fluorocarbon spraying + anodizing composite treatment

II. Key technology breakthroughs

Structural optimization

The hollow design of the main beam (wall thickness 4mm) reduces the weight of the steel structure by 40%

The spacing of wind-resistant columns is increased to 2.4m, passing the wind tunnel test (wind resistance level 12)

Surface treatment system

Process parameters of treatment layer Effect index Base chromization treatment Adhesion ≥ Level 1 Intermediate layer powder spraying Film thickness ≥ 60μm Surface layer fluorocarbon spraying Weather resistance

Intelligent integration

Eaves embedded photovoltaic film (conversion efficiency 18.5%)

Column built-in temperature Humidity sensor linkage spray system

III. Construction process innovation

Precision control: Total station assisted installation, node misalignment ≤1.5mm

Quick assembly: Single pavilion construction period shortened to 3 people/2 working days

Ecological adaptation: Removable foundation reduces damage to coral reef geology

IV. Benefit analysis

Economical efficiency: The life cycle cost is 37% lower than that of wooden structure

Maintenance cost: Annual average cleaning and maintenance cost <800 yuan/seat

Environmental protection value: Material recovery rate reaches 100%

V. Industry inspiration

This case confirms the applicability of aluminum alloy pavilions in special environments such as coastal and high humidity, and its modular construction mode provides new ideas for the rapid implementation of cultural and tourism projects.
