What is the difference of the 7th and 5th layers of the bottom of the steel pail？

The 7th and 5th layers of the back cover refer to the difference between the layers at the bottom of the steel pail.

The bottom of the steel drum with 7 layers of back cover is welded by 7 layers of steel plates, which is thicker and heavier than the 5 layers of steel plates, with higher strength and better durability, and is suitable for loading items with relatively large weight and higher requirements.

The bottom of the 5-layer steel drum is welded by 5 layers of steel plates, which is lighter than the 7-layer steel plates, but still has high strength and durability, and is suitable for loading light items or some general items.

Therefore, the selection of the number of layers needs to be decided according to the actual situation and needs to avoid wasting costs or causing instability of loaded items.
