Serra similarly works with industrial steel as a primary sculptural medium, creating large scale non representational forms that exploit the material properties of metal including weight, surface and industrial fabrication processes closely mirroring Chamberlain's approach in Heidi.

Di Suvero shares Chamberlain's commitment to abstract sculpture built from industrial steel components, embracing raw and treated metal surfaces to create dynamic non representational compositions that carry both formal strength and expressive personal energy.

Caro worked extensively with painted and welded steel to produce abstract sculptures that balance industrial material with painterly color treatment, a combination directly parallel to Chamberlain's use of painted and chromium plated steel in this intimate commemorative work.
