Much too heavy for practical use. You'd have to specify what type of trailer you had in mind. As far as all steel construction goes, the only ones you'd find are 53' flatbeds and stepdecks, armoured van trailers (very uncommon, but they are out there), and equipment trailers (RGN lowboys, RGN pontoon trailers, RGN beam trailers, etc.). Weights vary greatly between them.
As for a typical 53' van, the frames are steel, but the floor will be wood (or some use polymer), and the walls will typically be thin aluminum.
The net weight of a 53-foot standard semi-trailer typically ranges between 15,000 to 20,000 pounds (approximately 6,800 to 9,100 kilograms) when empty, depending on the trailer's construction and materials. The specific weight can vary based on the type of trailer (e.g., dry van, refrigerated) and additional features. It's important to check the manufacturer's specifications for accurate weight details.
Depends on the type and size of the rig, but a typical tractor weighs 15,000# and a 53' enclosed van trailer weighs about 13,000#, for a total of 28,000 lbs. Most US highways have an 80,000 pound weight limit, so the load capacity or maximum net weight of a typical tractor-trailer is 52,000 lbs.

Assuming you're referring to a 53' semi trailer, 41,000 - 43,000 lbs. for an 80k combination is typical.
A 53-foot semi-trailer typically weighs around 14,000 to 15,500 pounds when empty. This weight can vary depending on the materials used in its construction, such as aluminum or steel. Additionally, the weight can be affected by any additional features or equipment installed on the trailer.

The gross weight of a 53' dry van trailer typically ranges from 15,000 to 25,000 pounds when empty. When fully loaded, the total weight, including the trailer and cargo, can reach up to 80,000 pounds, which is the maximum legal weight limit for most highways in the United States. However, the exact weight can vary based on the trailer's construction and the materials used.
