How Much Do You Know About The Number Of Color Coated Boards?
2022-09-27
To identify the color coated plate brand, we need to know the naming method of the color coated plate. The naming of the color coated plate brand consists of three parts: color coating code, substrate characteristic code and substrate type code. A plus sign“+is used between the substrate characteristic code and substrate type code& rdquo; connect.
Color coating code: use“ Apply” The first letter of Hanyu Pinyin“ T” express.
Base plate characteristic code:
a) Steel for cold forming
When electroplating the substrate, it consists of three parts, of which the first part is the letter“ D”， Represents steel plates for cold forming; The second part is the letter“ C”， The representative rolling condition is cold rolling; The third part is a two digit serial number, namely 01, 03 and 04. 1536917957775214.jpg The hot plating substrate consists of four parts, the first and second parts are the same as the plating substrate, and the third part is a two digit serial number, namely 51, 52, 53 and 54; The fourth part is the letter“ D”， Represents hot plating.
b) Structural steel
It consists of four parts, of which the first part is the letter“ S”， Represents structural steel; The second part is a 3-digit figure representing the specified minimum yield strength (unit: MPa), namely 250, 280, 300, 320, 350, 550; The third part is the letter“ G”， Represents heat treatment; The fourth part is the letter“ D”， Represents hot plating.
Base plate type code
“ Z” Represents hot dip galvanized base plate,“ ZF” Represents hot dip galvanized iron alloy substrate,“ AZ” Represent hot dip aluminized zinc alloy substrate,“ ZA” Represents hot dip galvanized aluminum alloy substrate,“ ZE” Represents an electro galvanized substrate.
