What is high tensile steel?

High-tensile steels are low-carbon, or steels at the lower end of the medium-carbon range, which have additional alloying ingredients in order to increase their strength, wear properties or specifically tensile strength. These alloying ingredients include chromium, molybdenum, silicon, manganese, nickel, and vanadium.

How tight should a wire fence be?

It is hard to keep top and bottom wires tight on rolling ground. Do what you can with pulling or stretchers, then you may have to put a slight bend in each square of top or bottom wire, to tighten loose areas. We push wood post every 10′ and staple every wire on woven. Don’t drive staples quite tight.
