Is stainless steel welded ventilation duct or galvanized air duct installed in hotel kitchen?

In the hotel kitchen scene, stainless steel welded ventilation duct is a better choice, which can better meet the needs of high temperature, lampblack, humidity and cleaning in the kitchen, while galvanized air duct has obvious shortcomings in durability and adaptability.

1. Core difference: material characteristics adapt to the kitchen environment.

The core challenges of hotel kitchens are high temperature oil fume, oil stain adhesion and humid environment, and the material characteristics of the two kinds of air ducts directly determine the fitness.

Excellent corrosion resistance, can resist the corrosion of acidic substances and cleaning agents in the oil fume, and is not easy to rust after long-term use. The zinc layer is easily corroded by oil fume and water vapor, and will fall off and block the pipeline after rusting.

Strong high-temperature resistance, can withstand the high-temperature airflow generated by kitchen stoves, will not soften and deform weakly, and the zinc layer is prone to oxidation failure at high temperature, and the overall strength of the pipeline will decrease.

Surface smoothness: The inner wall is smooth, the oil stain is not easy to adhere, and the cleaning difficulty is low. The inner wall is relatively rough, and there may be tiny particles in the zinc layer, so the oil stain is easy to accumulate.

2. Long-term use: the comprehensive cost of stainless steel pipes is lower.

Although the initial purchase cost of stainless steel pipes is higher than that of galvanized air pipes, the comprehensive cost is lower from the perspective of the 5-10 years service life of kitchens.

Maintenance cost: the cleaning frequency of stainless steel pipes is low, and there is no need for frequent repair or replacement; Galvanized air duct is easy to rust and accumulate oil, so it needs to be replaced regularly, and the cost of manpower and materials for later maintenance is higher.

Service life: the normal use of stainless steel pipes can exceed 10 years; Galvanized air duct usually needs to be replaced in 3-5 years in kitchen environment, and the replacement cost will accumulate higher in the long run.

3. Safety and compliance: Stainless steel pipes are more in line with catering standards.

Hotel kitchens should comply with food safety and fire-fighting regulations, and stainless steel pipes are more secure in these two aspects.

Food safety: Stainless steel is stable, will not release harmful substances, and is easy to clean, which can avoid the secondary pollution caused by oil mildew in the pipeline and meet the hygiene requirements of the catering industry.

Fire safety: stainless steel is not easy to burn and will not produce toxic gas at high temperature; In the high temperature or fire scene of galvanized air duct, the combustion of zinc layer may release harmful gas, which has potential safety hazards.
