cold rolled Color coated 22 Gauge Corrugated Gi Galvanized Steel
Roofing Sheet 1.Galvanized steel plate is divided into ordinary electrolytic
plate and fingerprint resistant electrolytic plate.
Fingerprint-resistant plate is an additional fingerprint-resistant
treatment on the basis of ordinary electrolytic plate, which can
resist sweat. It is generally used on parts without any treatment,
and its brand is SECC-N. The common electrolytic plate can be
divided into phosphating plate and passivation plate. The
phosphating is more commonly used, and the brand is SECC-P,
commonly known as p material. Passivation plate can be divided into
oiled and non-oiled. 2.give an example: Hot dip galvanized steel sheet (SGCC) has one advantage over
electro-galvanized steel sheet (SECC). The bending and section of
SECC are very easy to rust. ate. The case steel plate made of this
material has bright color and metallic luster. The advantage of
this steel plate is good 3.Electro galvanized Under the same conditions, the rust resistance
of SGCC is much better. High-quality case usually adopts SECC or
SGCC galvanized steel plteel sheet (SECC): uniform gray, mainly
imported, fingerprint resistant, with excellent corrosion
resistance, and maintains the processability of cold-rolled steel
sheet. Use: household appliances, computer case shell and some door
panels and panels. Technical Standard | EN10147, EN10142, DIN 17162, JIS G3302, ASTM A653 | Steel Grade | Dx51D, Dx52D, Dx53D, DX54D, S220GD, S250GD, S280GD, S350GD, S350GD,
