We received some nice Carbon masts for some H20 project years ago. All looked to have been folded to fit in a shorter truck. Heart breaker!
Those cardboard tubes are strong, but a pallet of 50 gallon drums full of product... being pushed by either a forklift or a sudden stop on the highway are sure to crush everything in their path.
To avoid damage, we try to ship on only our own full loads. We have many full trucks headed out every day, so that makes it easier.
