Brisbane has a subtropical climate. Warm, humid conditions and periods of heavy rain should be considered when planning replacement air, external exhaust outlets and weather protection. Salt exposure varies by site, particularly near the coast, and should inform material selection and maintenance.
Extraction capacity should be calculated from cooking equipment, heat output, canopy design and duct resistance. Kitchen ventilation and cooling should be considered together; grease filters capture grease and do not control humidity.
Weather Protection for External Exhaust Components
Heavy rain, strong winds, and severe weather can affect external exhaust outlets, ductwork, and ventilation components if they are not properly designed and installed.
Commercial kitchen exhaust systems should be planned with appropriate weather protection, drainage, and installation considerations for the site.
CGC Stainless Steel can work with builders, contractors, and commercial kitchen operators to consider the location of exhaust outlets, external ductwork, and other ventilation components when designing a Brisbane commercial exhaust system.
What Corrosion Options Are Available for Brisbane's Salt Air?
Commercial kitchens located near Brisbane's coastline or exposed to salty coastal air may require additional corrosion-resistance considerations.
For components exposed to marine salt, 316 stainless steel generally provides greater corrosion resistance than 304. The appropriate grade depends on exposure, surface finish, cleaning access and the component's application. More aggressive conditions can require higher grades; stainless steel still needs suitable fabrication and regular cleaning.
Depending on the project and exposure conditions, our team can recommend suitable stainless steel options and fabrication specifications for commercial range hoods, exhaust canopies, and associated components.
Brisbane-Specific Ventilation Considerations
When planning a commercial kitchen exhaust system in Brisbane, we consider factors such as:
- Local climate and humidity
- Exposure to coastal or salt-laden air
- External ductwork locations
- Heavy rainfall and storm conditions
- Cooking heat, smoke, and grease loads
- Kitchen layout and equipment
- Exhaust outlet positioning
- Long-term maintenance requirements
