Tank Heads

Inconsistent heads? Let Glenn Metalcraft be your solution! We can replace your stamped, fabricated, or bump rolled heads with spin forming!

Glenn Metalcraft Inc. specializes in spun formed heads from 8” to 120” in diameter and up to .500” thick.  Our state-of-the-art CNC spinning machines allow us to spin form many variations of heads to exacting dimensions with high repeatability with lower initial costs.

We have found with new customers that GMI-supplied parts offer significant manufacturing cost reductions because of the part to part reliability.
