Abstract

A method including manufacturing a trough. The trough includes connected walls configured to hold a molten galvanization material within the trough. The trough is further manufactured to include a first end including a first gate system. The trough is further manufactured to include a second end, opposing the first end, including a second gate system. The trough is further manufactured to include a roller connected, inside the trough, to opposing inside walls of the connected walls. The trough is further manufactured to include a sump disposed within the trough. The trough is further manufactured to include a side braces connected to an outside wall of the connected walls. The side braces extend outwardly from the outside wall. The trough is further manufactured to include an inlet connected to the sump, the inlet disposed at a perpendicular angle relative to the outside wall and further disposed between the side braces.

7 . The method of claim 5 , wherein:

the first gate system is further manufactured to comprise a gate, and

the gate comprises a workpiece channel disposed in a side wall of the gate, wherein the workpiece channel is disposed in the gate to align with a groove of the roller along a horizontal axis of the trough.

8 . The method of claim 5 , wherein:

the first gate system is further manufactured to comprise a gate, and

the gate comprises:

an outlet disposed in a side wall of the gate; and

a workpiece channel disposed in the side wall of the gate below the outlet, relative to a direction of gravity when the gate is installed in the trough for use, wherein the workpiece channel is disposed in the gate to align with a groove of the roller along a horizontal axis of the trough.

9 . The method of claim 5 , wherein:
