Glass Patterned Coating Step-by-Step Process Explained In Depth

  • Patterned coating glass is a decorative and functional type of glass widely used in architecture, interior design, doors, partitions, and facades. It combines two main features:
  • Patterned (Textured) Surface -for visual appeal and privacy
  • Coated Surface -for performance enhancements like solar control or reflectivity

Step 1: Raw Glass Selection

The process begins with selecting high-quality float glass as the base material. This is the standard, flat, clear glass used in most glazing applications.

  • Thickness: Usually between 3 mm and 10 mm
  • Glass Type: Clear, ultra-clear (low iron), or tinted

Step 2: Patterning the Glass Surface

To create the decorative pattern or texture, the glass undergoes rolling while still hot.

Here’s how it works:

  • The glass is heated to ~1000°C in a furnace until it becomes soft.
  • It passes between two engraved rollers – one or both rollers have patterns engraved on their surfaces.
  • The design is imprinted onto the softened glass as it passes through.

Common Patterns: Squares, dots, lines, raindrops, abstract textures

Step 3: Annealing or Tempering

After the patterning, the glass needs to be cooled down properly.

  • Annealing: Slowly cools the glass to relieve internal stress
  • Tempering (Optional): If safety or strength is required, the patterned glass may be tempered (heat-strengthened) to increase its strength by 4–5 times.
  • Tempered patterned glass is also shatter-resistant.

Step 4: Cleaning and Surface Preparation

Before applying any coatings, the glass is thoroughly cleaned using deionized water and brushes in a washing machine.

This step ensures:

  • No dust or particles remain
  • Coating adhesion will be uniform and effective

Step 5: Coating Application

Now comes the coating stage, where a thin functional layer is applied on one side of the glass. The coating adds properties like:

  • Solar control (reflects heat)
  • Low-E (low emissivity) (improves insulation)
  • Anti-reflective or decorative effects

Two Common Coating Techniques:

Magnetron Sputtering (Vacuum Coating):

Glass is placed in a vacuum chamber.

Metal or metal-oxide atoms (like silver, titanium, or zinc) are deposited in a very thin layer.

Provides high-performance coatings.

Pyrolytic Coating (Online Coating):

A coating is sprayed onto hot glass during the float glass production process.

More durable but less efficient than magnetron coatings.

Step 6: Quality Inspection

Every sheet of patterned coating glass is inspected for:

  • Pattern consistency
  • Coating uniformity
  • Scratches, defects, or color variations
  • Modern inspection systems use lasers and cameras to detect flaws.

Step 7: Cutting and Edge Finishing

The glass is then cut into required sizes, and the edges may be:

  • Polished
  • Beveled
  • CNC processed for holes or notches
  • This makes it ready for installation or further lamination.

Step 8: Packaging and Delivery

  • Finally, the finished glass is:
  • Stacked carefully with protective layers
  • Packed in crates or metal frames
  • Shipped to clients in the construction, interior, or glazing industries
