Hi...are there any metal experts out there?
I'm getting quotes for our radar/solar panel arch and I'm getting different feed back from different welders and metal workers.
One fabricator says he won't fabricate anything in aluminum
due to the poor tensile strength properties. He states he has repaired too many aluminum
arches to count and only does fabrication of arches in stainless steel
Another fabricator I talked to said he could and would do it in aluminum if I wanted. It's about half the cost compared to s/s. He said he has done many jobs using 60/63 grade aluminum. He said it has very high grades in anti-corrosion and welding.
Does anyone have any feedback regarding either of them?
What is your experience with aluminum vs stainless steel
