Intro<\/h2>\n

Electro galvanized steel \u2014 EG for short \u2014 is cold-rolled steel with a thin zinc layer plated on by electrolysis. The coating runs 5-15 \u00b5m: smooth, matte, no spangle. If the part lives indoors and has to look right, this is the sheet you’re after.<\/p>\n

The difference from hot-dip starts on the surface. Electroplating deposits zinc at room temperature, so the coat comes out even and spangle-free \u2014 no crystalline pattern, no drips. Paint grips it well, and with phosphate pre-treatment you can skip the grinding and go straight to the paint line. For panels that sit in a showroom, that surface is the whole sale.<\/p>\n

Formability is where EG earns its keep. Plating happens cold, so the base steel keeps its full mechanical properties \u2014 deep drawing, stamping, bending \u2014 and the coating flexes with the metal instead of cracking at the radius. Welding is clean too, with a fraction of the zinc fume you get from hot-dip. Coating weight runs 5-50 g\/m\u00b2 per side, typically 20-40 g\/m\u00b2, and because plating is set by current and time, it comes out the same batch after batch.<\/p>\n

EG is a parts material. Anything that lives indoors and has to look decent gets spec’d in it \u2014 the zinc protects cut edges and small scratches, and the surface carries paint without complaints. Same sacrificial principle as hot-dip: the zinc corrodes first, the steel underneath stays. The protection window is shorter than HDG, so keep it under cover.<\/p>\n
