Hosebed Divider Thickness
For all of you involved regularly with specs and manufacturing:
What are most apparatus manufacturers and shops using as their standard thickness aluminum for adjustable hosebed dividers? Do any of the manufacturers offer an option for an upgrade or downgrade in thickness, and/or is there a certain divider height (e.g. hosebed taller than 18") at which they automatically chose the thicker material?
Any information on current and (recent) past practices is helpful. Thanks.
