Tredegar Corp.

A manufacturer based in Richmond, Virginia that makes custom aluminum extrusions (through its Bonnell Aluminum brand) for buildings and transportation, plus protective polyethylene films that shield delicate electronics during shipping. Its name traces back to the historic Tredegar Iron Works, a Civil War-era foundry that supplied roughly half the Confederate army's artillery. The modern company was born in 1989 as a spinoff from the chemical firm Ethyl Corporation.
