Tempered Glass with Polish Edge | Safety Glass with Precision-Finished Edges from KINGSTAR BUILDING GLASS
KINGSTAR BUILDING GLASS Tempered Glass with Polish Edge is a high-strength safety glass product that combines the impact resistance of fully tempered glass with precision-ground and polished edge finishes. The edge polishing process is performed on each glass panel prior to thermal tempering, as tempered glass cannot be cut, ground, or polished after heat treatment. Available in flat polish, pencil polish, and bevel edge configurations, with polished edges providing superior aesthetics, enhanced
Tempered glass with polished edge is a safety glass product where the cut edges of the glass panel have been precision-ground and polished to achieve a smooth, glossy, transparent finish. The polishing process removes sharp edges, micro-cracks, and surface imperfections, resulting in a refined appearance and improved edge strength.
The edge polishing process for tempered glass follows a specific sequence:
All edge work, including grinding and polishing, must be completed before the glass undergoes thermal tempering. Tempered glass cannot be cut, ground, or polished after heat treatment.
KINGSTAR BUILDING GLASS offers multiple polished edge profiles to suit different applications and aesthetic requirements:
Flat Polish
Flat polishing involves cutting the edges of the glass and then flat polishing them, resulting in a sleek appearance with a shiny or glossy finish. Most flat-polished applications also employ a small chamfer on the top and bottom glass edges to remove sharpness. Flat polished edges are commonly specified for glass railings, balustrades, and furniture where the full edge thickness is visible.
Pencil Polish
Pencil polished glass edges are ground smooth, finished with a shiny or glossy polish, and feature a slight curve. The edge radius is similar to a pencil or C shape. The unique finish makes pencil polishing ideal for shower enclosures, interior partitions, and applications where a smooth, rounded edge is desired for both safety and appearance.
Bevel Edge
Bevel edges are created by grinding the edge at an angle, typically 15 to 45 degrees, to create a sloped, decorative edge. Beveled edges are most often seen on mirrors, tabletops, and high-end architectural applications.

Q1: Can tempered glass edges be polished after the tempering process?
A: No. All edge grinding and polishing must be completed before the glass undergoes thermal tempering. Tempered glass cannot be cut, ground, or polished after heat treatment. This is why all edge finish specifications must be provided before production begins.
Q2: What is the difference between flat polish and pencil polish for tempered glass edges?
A: Flat polish produces a straight, flat edge surface with a glossy, transparent finish, typically with a small chamfer on the top and bottom edges to remove sharpness. Pencil polish produces a rounded edge with a glossy finish, where the edge radius is similar to a pencil or C shape. Flat polish is commonly used for railings and furniture where the full edge thickness is visible, while pencil polish is preferred for shower enclosures and applications where a smooth, rounded edge is desired for safety and aesthetics.
Q3: What standards do KINGSTAR BUILDING GLASS tempered glass with polished edge products comply with?
A: KINGSTAR BUILDING GLASS tempered glass with polished edge complies with EN 12150-1 (thermally toughened soda lime silicate safety glass) and EN 12600 (impact test method and classification). The polished edges are finished to industry standards for glass edge finishing.
Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to shatter into small granular chunks instead of splintering into jagged shards as ordinary annealed glass does. The granular chunks are less likely to cause injury.
No tong marks on the glass as adopts the horizontally tempering process.
5 times harder than ordinary annealed glass.
Once breakage occurs, the glass disintegrates into small cubical fragments which are relatively armless to human body.
It withstands abrupt change of temperature. For example, a piece of 5mm tolerate the temperature variations within the range of 200°C.
Tempered glass should under go heat soak test to improve safety in use.
Thickness: 3-19mm
Size: Min size 300*200mm,Max size 3300*15000mm
Tempered glass is used for its safety and strength in a variety of applications, including passenger vehicle windows, shower doors, aquariums, architectural glass doors and tables, refrigerator trays, mobile phone screen protectors, bulletproof glass components, diving masks, and plates and cookware.
