Multipurpose 6061 Aluminum Sheets and Bars
The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant, plus it's easy to machine and weld.
Extruded sheets and bars are formed by a die for close-tolerance widths, then cut to the lengths listed.
Aluminum that meets ASTM B209 or ASTM B221 complies with standards for materials.
Aluminum that meets an SAE AMS standard conforms to the material and process needs of the aerospace industry.

Slippery UHMW Polyethylene Sheets, Bars, and Strips
In addition to having a low-friction surface that prevents sticking and binding, this tough, impact- and wear-resistant material handles the scuffs, scrapes, and strikes that other plastics can’t. These sheets, bars, and strips are often used to make machine guards and chute liners. They are all FDA compliant for direct food contact.

Clear Scratch- and UV-Resistant Cast Acrylic Sheets, Bars, and Cubes
These cast acrylic sheets, bars, and cubes are often fabricated into tanks, see-through barrier panels, and light fixture lenses. Cast acrylic, which is comparable to Lucite and Plexiglas® Acrylic, is easier to machine than extruded acrylic. This material is scratch and UV resistant; it stands up to outdoor use better than polycarbonate and maintains clarity over time.
