The commercial quality hot dip galvanized steel is a type of steel that can be made after galvanizing a coil of SPCC cold rolled material. The Zinc coating thickness is based on the thickness and width and is governed by JIS G 3302.
Dimensional Characteristics of SGCC Steels: The applicable thickness for this SGCC material as defined in the JIS G3302 starts from 1.6 mm to 3.2 mm. However the width of SGCC material ranges to over 1600 mm.
The Chemical Composition of SGCC Steels: JIS G 3302 defines the chemical composition of SGCC steels as under:
Maximum percentage of Carbon (C) is 0.15 percent.
Maximum percentage of Manganese (Mn) is 0.80 percent.
Maximum percentage of Phosphorous (P) is 0.050 percent.
Maximum percentage of Sulphur (S) is 0.080 percent.
Remaining is iron (Fe) percentage and with few negligible impurities.
Mechanical Properties of SGCC Steels: The tensile strength of the SGCC Steels is expressed in Newton per millimeters and it must be at-least 270 N/mm2 (MPa).
The elongation property of SGCC is not defined.
The hardness of SGCC material is also not exactly defined in JIS G 3302; however as per understanding it should be less that 65 HRB.
Galvanized steel refers to the ordinary carbon construction steel after galvanized processing can effectively prevent steel corrosion and rust so as to prolong the service life of steel, including galvanized galvanized and hot dip galvanized. Generally used for building exterior walls, such as glass curtain wall, marble curtain wall, aluminum curtain wall to do columns and stress materials, or used for outdoor telecommunications tower, highway and other open-air construction steel known as galvanized steel, which galvanized: electric galvanized and hot dip galvanized.
