Yes. It is hard to install correctly, and requires a professional using a post driver and specialized equipment to achieve full life expectancy of materials used. Since it is made of high tensile steel, it requires stretching to the proper tension and brace assemblies that can withstand this tension. The strength of high tensile fencing allows you to use a smaller wire, while increasing the strength of your fence. The smaller wire weighs less, therefore making installation easier and allows you to increase pole spacing.
