What’s the difference between aluminum and steel floor registers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAluminum won’t rust, weighs less, and accepts cleaner powder-coat finishes — especially important in bathrooms, laundry rooms, and kitchens where humidity is a factor. Steel handles heavier commercial loads but corrodes in moist environments over time.
