Stainless Steel vs Aluminium
1. Corrosion Resistance
When compared to aluminium, stainless steel has a much higher resistance against corrosion. This is due to the additional Chromium and Nickel addition to its chemical composition. Moreover, stainless steel is non-porous, which will increase its resistance to corrosion. If used outdoors, as in the case of exposed areas with or without awning and/or wet areas, erosion and corrosion from the wind, rain and sun are important considerations. Good-grade stainless steel will be able to stand up to the elements and remain clean and tidy for the years to come with regular cleaning.
Aluminium, on the other hand, relies on a passivation layer for its oxidation and corrosion resistance. If that layer is scratched or oxidized, its surface will turn white or clouded and even pit (formation of tiny holes) in the long run.
2. Cooking Applications: Food-safe
Just take a look around you. Professional kitchens, be it the high-end restaurants in the CBD or your favourite local hawker stall, generally choose to go for stainless steel cabinetry as their choice of kitchen cabinet material.
The general first rule in food preparation is hygiene and cleanliness. Stainless steel surfaces are less reactive than aluminum ones due to its neutral chemical composition, which makes it very suitable for areas of cooking.
Aluminium surfaces, however, can react with foods that will affect the taste and colour and may even leach into them. Thus, in food preparation areas of high probability of contact with acidic and abrasive food items (e.g. vinegar, salt, soy sauce, tomato sauce), stainless steel may be a better choice instead.
3. Strength
Stainless steel is a material that is strong, durable and long-lasting due to its higher overall density. For areas that will be subjected to heavy usage and are needed to store and hold heavy items (think: porcelain dinner plates, cooking woks and pots, bowls and cutlery), stainless steel will be able to hold up to the challenge, quite literally. For many commercial kitchens, sinks and countertops, it is often made up of stainless steel due to its high-performing properties.
4. Thermal Properties
Stainless steel can withstand higher temperatures than aluminum, which can become soft in the same temperature. It also absorbs heat at a slower rate than aluminium, which means your space remains relatively cool, even when you have been busying in it for a long time.
5. Cost
Stainless steel is generally more expensive than aluminium, but it also lasts longer, which makes it very cost-effective in the long-run. The price tag will be well worth the investment should you use it in the right areas to save yourself more trouble in the future. This is especially so in the bigger-ticket items in your renovation list, such as the kitchen or bathroom, which will be difficult and costly to redo.
Remember: your house, your choice. Staying true to your preferences and choosing materials that best fit your lifestyle is the way to go. For many, that would mean simple cleaning and maintenance, but an equally stunning household. Stainless steel material for water-prone and/or cooking areas will be able to help you achieve that fuss-free life you desire, and keep your spaces beautiful, hygienic and timeless.
