AASHTO M 280-20 is a standard specification that outlines the requirements for metallic-coated steel barbed wire. It specifically focuses on barbed wire that is composed of a strand made up of two wires.

The standard covers different types of coatings that can be applied to the barbed wire, including aluminum, zinc, and zinc-5 percent aluminum-mischmetal alloy. These coatings can vary in their weight, and the standard specifies the acceptable range for each coating type.

Additionally, the standard considers the various design options for the barbed wire, which may differ in construction. It is important to note that not all designs are available for every type of coating.

The standard also includes two grades for the metallic-coated steel barbed wire, which indicate different levels of quality.
