Featured Product

LDI manufactures a wide range of cylindrical tanks.  Our automated cell consists of a CNC plate rolling machine which forms cylindrical tank bodies from material up to 1/4" thick by 72" wide and a robotic welder which has dual sided tables for continuous operations.  The robotic welder is capable of processing tanks 24'' - 30" in diameter and up to 66" long.

We can also provide steps & ladders, brackets, guards, and clean out covers that are added to the tank. Additionally, other work centers are equipped to produce both smaller and larger diameter cylindrical tanks.
