  When drilling holes, you need to pay attention into the Vietnamese standard specification for heat-treated flat glass - TCVN 7455:2013 to prevent break the glass: 

•    Glass edge finishing, hole drilling must be done before the glass is tempered to become tempered glass.
•    The distance from the edge of the hole to the edge of the glass must not be less than 2 times the thickness of the glass, so the glass around hole’s position will not be broken when tempered.
•    The distance of 2 holes must not be less than 2 times of the thickness of the glass.
•    Diameter of hole must be equal or longer than the thickness of the glass. For example, the smallest hole diameter should be 10mm if the glass, thickness is 10mm, to reduce the unsafe potential for users.

 

   The thickness of tempered glass is from 5mm to 25mm, in which the thickness of 10mm - 12mm is commonly used for making glass doors and partitions; modern bathroom. Glass fittings for each type of glass products is an indispensable part to ensure the function and safety.
