I picked this arch because of the price and the good strong specifications of the product. Its around 34 Kilo and I liked the size of the support posts 2.5 inches square. I don't need it to come down in strong winds. Although the timber is treated I gave it a further coat of fence paint while on the ground, the same colour as all my fencing.  It came in good time, well wrapped and with all screws and a drawing how to put it together. If you are man enough to put this arch up yourself I fail to understand why drilling  screw holes will be a problem for you.
