SPCC vs. SGCC vs. SECC steel for computer cases
· - SPCC is "commercial quality, cold rolled carbon steel" per Japanese standard JIS G3141, so you might want to obtain that specification. - SGCC is probably hot dip galvanized. Although some say that the "CC" stands for chromate coated, I disbelieve that and assume it means "cold rolled, coil" or "cold rolled, commercial quality".
