Can you tell me why?

Surely, while on the road, there have been times when you’ve seen a truck carrying coils of steel (like the image) and if you’re curious, you might have wondered why steel coils are loaded in such a staggered manner? Why are they placed vertically (with two round holes facing outward on each side) instead of horizontally for safety?

Because This type of stand is for ease of transport. As for safety, it depends on how tight the driver of the said car is. From the picture, the weight must be at least 20 tons, there should be 4 or more chains, regular coils.
