Gauge 28 vs Gauge 30 Mabati: Which Should You Buy?

The verdict

Gauge 28 is thicker, quieter in rain and lasts longer, at KSh 720 to 800/m for box profile. Gauge 30 (KSh 480 to 650/m) is the standard house choice and fine for most roofs. Pay for G28 on a permanent home or a coastal, high-rust area.
