is used for construction materials, electrical appliances, etc. It is made by hot rolled flat 
steel which is processed further by hot -dip zinc coating or/and oil coating chemical 
treatment.  
The scope excludes:  
- Hot-dip galvannealed flat steel  
- Other hot -dip zinc -coated hot rolled flat steel which is regulated as a voluntary standard 
such as hot -dip galvanized and galvannealed flat steel for automobile uses (TIS 2985 - 
2562(2019))  
- Other hot -dip zinc -coated hot rolled flat steel with other elements which is regulated as 
a voluntary standard such as hot -dip zinc -5% to 13% aluminium -2% to 4% magnesium 
alloyed -coated flat steel (TIS 29 81 - 2562(2019))  G/TBT/N/THA/642  
 
- 2 - 
 
  This standard specifies types, grades, chemical composition, mechanical properties, zinc 
coating, oil coating, chemical treatment, mass and tolerances on dimensions and shape, 
appearance, marking and labelling, sampling and criteria for co nformity, etc.  
7. Objective and rationale, including the nature of urgent problems where 
applicable:  Prevention of deceptive practices and consumer protection; Protection of
