- Most common sheet metal is 29 ga, with a little less in 26 ga (barn roof, siding, etc). Galvalume appears to be galvanized with ZA alloy (55% Al, 45% Zn). [1]
- Galvalume - last 2x that of galvanized only? [2]. Galvalume regularly lasts 60+ years. [3]. BS alert apparently, as galvalume was introduced only 50 years ago.
- Pro-rib standard at Menards is 29 ga [4]
- Typical metal brake does 29 ga [5]
- Van mark $2k - 26 ga [6]
18 gauge
- It is 1 mm [[7]] and 2 lb/sf [8]. Thus a 8x4 foot sheet is 64 lb. Lighter than OSB at 75 lb for 3/4".
- Design formulas [9]
