7mm Metal Angle Bar Engineering Structures 904L Mild Steel Angle Bar
Is stainless steel better than aluminum?
With good corrosion resistance properties, aluminium does not rust. But stainless steel takes the advantage here as it has chromium added, giving it a protective film and excellent corrosion resistance. Stainless steel is also non-porous, giving it an extra level of corrosion resistance.
