Product introduction

3003 aluminum alloy is the most widely used of all aluminum alloys. It is essentially commercially pure aluminum with the addition of manganese which increases the strength approx. 20% over 1100 grade aluminum alloy. 3003 may show slight discoloration when anodized, but it reacts well to mechanical and organic finishings.

Aluminum alloy 3003 plate sheet is also produced as a bright finish tread plate (also known as checkered plate) with industrial and decorative applications. Aluminum tread plate in alloy 3003 is typically used in decorative architectural applications, due to its bright reflective finish. It is usually produced in a “1-bar” or “ 5 bars” tread pattern.
