1、 Can tempered glass be perforated

Tempered glass can be perforated.

Tempered glass is quite common in modern decoration, especially in balconies, bathrooms, and other places where it is frequently used. And some people are not familiar with tempered glass, so can tempered glass be perforated?

Rules for opening tempered glass:

1. Only tempered glass with a width greater than 8 times the thickness can be drilled.

2. For tempered glass with a thickness not exceeding 12mm, the distance from the hole edge to the edge of the glass should not be less than 1.5 times the thickness of the glass; Tempered glass with a thickness exceeding 12mm should have a distance from the edge of the hole to the edge of the glass not less than twice the thickness of the glass;

3. The diameter of the circular hole on tempered glass should be 1.6mm larger than the thickness of the glass; the diameter of the circular hole should be less than one-third of the width; The radius of the corner of the irregular hole on the glass plate should be greater than the thickness of the glass.

When drilling at an angle of not less than 90 degrees, the distance from the edge of the hole to the corner should be greater than 6.5 times the thickness of the glass.

5. The concave part should use a rounded corner radius not less than the thickness of the glass.

2、 How to drill holes in tempered glass

Tempered glass is actually a type of prestressed glass. To improve the strength of glass, chemical or physical methods are usually used to create compressive stress on the surface of the glass. When the glass is subjected to external forces, the surface stress is first counteracted, thereby improving its load-bearing capacity and enhancing its resistance to wind pressure, heat and cold, impact, etc

The stress of the glass itself has reached a balance, and once external forces (such as drilling or polishing) disrupt the stress balance of the glass itself, it will "self destruct" and break into slag.

Generally speaking, tempered glass cannot be drilled. If you want to drill holes, it is recommended to use ordinary flat glass to drill holes before tempering treatment If we want to delve deeper, using lasers can drill holes, but it is difficult, expensive, and not something that ordinary people can do.
