It's crucial to check with the specific supplier or manufacturer for accurate information on the weight of their barbed wire per meter, as it can be influenced by factors such as the material composition and the spacing and type of barbs. Additionally, different regions may have different standards and specifications for barbed wire, so local regulations and industry standards should also be considered.

If you have a specific type or brand of barbed wire in mind, it's recommended to consult the product specifications provided by the manufacturer or supplier to obtain precise information on the weight per meter.
