It all needs to be 6ft high (the borough will not allow more), with one gate in the front. My preference (looks wise) would be aluminum. I need 100 feet of it (and 160 ft of chainlink).I can install it myself without a problem, so the question is about the product.

I went to a couple of lumbar yards and lowe's and have found the following products:
1. Lowe's sells Gilpin, Merchants Metals and Rockland - the salesperson recommended Rockland but the don't keep any samples in stock so I could not touch it.
2. the other contractors around here carry either Regis or Alumi-Guard.

So My questions are:
1. Are any of the 3 brands sold by Lowe's worth saving $1000. Are they that bad...I would really appreciate some objective answers here.
2. if Lowe's products are junk, what about Regis or Alumi-guard? Is their residential grade good enough? I know they also have a commercial or industrial grade, but the price really jumps up.

I don't need something spectacular, I just need somethng that will stand up without problems for 10 years, given the Pittsburgh weather.

An suggestions would be very much appreciated, i am kinda lost. I could really use the extra bucks I would save, but I don't want to buy junk that needs replaced within 6 months. Thank you!
