ALUMINUM ANGLES
Along with steel, aluminum roll forming makes up a large portion of Roller Die's business. Our engineers understand when aluminum is preferable for a specific end product. For one, aluminum has approximately one-third the density of steel, which is often ideal for use in roll formed Aluminum Angles. Many end uses of Aluminum Angles demand a lighter metal, intended for structures that move. Another benefit of aluminum? All grades and finishes that are cold-workable at room temperature can be rollformed.
Aluminum Angles cater well to transportation vehicles -- operating on Earth and beyond. Aluminum Angles and other roll formed shapes are especially active in the Aerospace, Automotive, Marine & Solar industries. Continued exploration of space and sea means Aluminum Angles will increase in popularity this century. Contact us to describe your upcoming Aluminum Angle project.
Standard Angle Part Dimensions
