Supporting the Heavy Demands of Kitchen Ventilation
Commercial kitchen equipment creates substantial structural loads—massive exhaust fans, heavy ductwork, rooftop makeup air units, and grease-laden systems all require proper reinforcement to protect your building and ensure reliable operation.
What We Reinforce
- Rooftop Exhaust Fans – Large upblast or inline fans requiring substantial support
- Makeup Air Unit Platforms – High-capacity units serving kitchen ventilation demands
- Kitchen Exhaust Ductwork – Heavy 16-gauge welded steel requiring proper hanger spacing
- Curb and Equipment Pads – Distributing loads across roof structure safely
Why Kitchen Systems Need Extra Support
- Equipment Weight Concentration
Kitchen exhaust fans and makeup air units weigh significantly more than standard HVAC equipment. Roofs and ceilings need reinforcement to carry these concentrated loads safely. - Vibration Management
High-CFM exhaust fans create substantial vibration. Proper structural support prevents transmission to dining areas and building damage over time. - Code-Required Safety
Building officials require engineered support for mechanical equipment. Kitchen installations face extra scrutiny due to fire safety considerations. - Grease System Considerations
Heavy-gauge welded ductwork weighs considerably more than standard systems. Support structures must account for this additional mass plus grease accumulation.
Kitchen-Specific Challenges
- Grease Duct Weight – Accounting for both duct construction and grease accumulation over time
- Multi-Fan Installations – Supporting several large exhaust fans on single roof structure
- Vertical Riser Support – Reinforcing multi-story exhaust duct pathways
- Equipment Replacement Access – Designing support systems allowing future equipment changes
Preventing Common Problems
Proper reinforcement eliminates issues before they start:
- Sagging ductwork affecting exhaust performance
- Excessive vibration reaching dining areas
- Roof damage from inadequate equipment support
- Failed inspections from improper installation
Historic Building Adaptations
Older buildings becoming restaurants need modern kitchen systems. We add necessary structural support while respecting architectural integrity and working within existing limitations.
Vibration Isolation Integration
Kitchen exhaust fans run continuously at high speeds. We design reinforcement that remains rigid under static loads while allowing vibration isolation systems to function properly.
Seismic Considerations
In seismic zones, kitchen equipment needs proper bracing and restraints. We incorporate all required seismic protection while maintaining system functionality and code compliance.
Where we are essential
Reinforcement Methods We Use
Kitchen ventilation equipment represents major capital investment. Proper structural support ensures decades of reliable operation without settlement, shifting, or performance degradation.
