Edge Finishing Types
What Is Glass Edge & Corner Finishing?
Glass edge and corner finishing refers to secondary processing applied to the edges and corners of glass after cutting.
Its purpose is not only cosmetic — it is essential for safety, strength, assembly accuracy, and product quality.
In simple terms:
Edge finishing determines whether glass is safe to touch, durable in use, easy to assemble, and premium in appearance.
Why Is Edge & Corner Finishing Necessary?
After cutting, raw glass edges are:
Sharp and dangerous to handle
Prone to micro-cracks that may lead to chipping or breakage
Edge and corner finishing helps to:
✓ emove sharp edges and reduce injury risk
✓ Minimize micro-cracks and improve durability
✓ Prevent edge chipping during transport and assembly
✓ Improve visual quality and perceived product value
