Custom toughened glass shower doors


For custom shower doors, safety-tempered glass is mandatory. It's stronger and shatters into small, blunt granules if broken, minimizing injury risk. Thickness selection is critical:
  • 8mm: Most common, offers good stability.
  • 6mm: Suitable for small doors or fixed panels.
  • 10/12mm: Used for oversized or frameless doors, providing maximum solidity.

Optional features enhance function and aesthetics: laminated glass (extra safety), frosted/sandblasted glass (privacy), Low-E glass (heat retention).

Hole-drilling processes are vital:

  1. Timing: All holes (for hinges, handles, etc.) MUST be drilled BEFORE tempering. Drilling after tempering causes instant shattering.
  2. Precision: Holes require exact measurement and positioning based on design drawings, typically using specialized equipment (like CNC machines or waterjets) for accuracy.
  3. Edge Treatment: Hole edges must be finely ground and polished to remove any chips or micro-cracks. This prevents stress concentration (which can cause spontaneous breakage) and ensures smooth, secure hardware installation.

In short: Choosing the correct, safe glass thickness and ensuring precise pre-tempering hole drilling and polishing are core to the safety and durability of custom shower doors.

Tempered Glass: The Safe & Strong Choice - Professional Manufacturing & Customization by Joy Shing Glass


     In modern architecture, home design, and industrial applications where aesthetics meet safety demands, ordinary glass often falls short. Tempered glass, renowned for its exceptional strength and unique safety properties, stands as the trusted solution. As experts in glass manufacturing, Joy Shing Glass breaks down the core advantages and types of tempered glass, delivering reliable, professional manufacturing services.



1. Tempered Glass: More Than Just "Harder" Glass

Tempered glass (also known as toughened or safety glass) is created by subjecting high-quality float glass to a precisely controlled thermal process (heating to high temperatures followed by rapid, uniform cooling). This process builds powerful compressive stress layers within the glass, granting revolutionary properties:

Multiplied Strength:

Impact resistance 3-5 times higher than ordinary glass; bending strength 2-3 times higher.

Superior thermal shock resistance, withstanding temperature differentials up to 200-250°C, minimizing the risk of thermal breakage.

Safety First:

Core Advantage! Upon forceful impact, it shatters instantly into countless small, blunt, honeycomb-like granules, drastically reducing injury risks – making it true "safety glass".

Reliable & Durable:

High strength ensures better resistance to scratches, abrasion, and everyday impacts, extending its lifespan.

> Joy Shing Glass Key Note: Once tempered, glass cannot be cut, drilled, or reworked. All customization needs (size, shape, holes) must be finalized before the tempering process – a crucial step in our professional manufacturing flow.


2. Tempered Glass Types for Diverse Needs (All Customizable by Joy Shing Glass)

We offer a diverse range of tempered glass products to meet your specific project requirements:

1By Strength & Safety:

Fully Tempered Glass: The Standard Choice! High strength, excellent safety (granular breakage). Widely used in doors, windows, curtain walls, shower enclosures, furniture tops, appliance panels – anywhere requiring personal safety protection(Joy Shing Glass Core Product).

Heat-Strengthened Glass: Moderate strength (~2x ordinary glass). Breaks into larger, sharper shards – not classified as safety glass. Suitable for applications needing high flatness, moderate strength, and no strict safety         requirements, like some interior partitions or curtain walls (designed to prevent total fallout). Always confirm safety needs!

2By Shape:

Flat Tempered Glass: The most common type, available in various thicknesses.

Bent Tempered Glass: Specialized Craftsmanship! Glass is heated, bent to a specific curve, then tempered, combining strength with elegant form. Ideal for curved facades, architectural features, premium furniture, display cases. Joy Shing Glass utilizes advanced bending/tempering technology to accurately realize your design vision.

3By Functional Combination (Often using Tempered Glass as Base):

Tempered Laminated Glass (PVB/SGP): Tempered glass + high-strength interlayer (e.g., PVB or SGP film). Even if shattered, fragments adhere to the interlayer, preventing penetration and fallout – top-tier safety! Essential for skylights, canopies, railings, banks, and high-risk curtain walls. Joy Shing Glass offers various interlayer options for different safety grades.

Tempered Insulated Glass Unit (IGU): Tempered glass + sealed dry air/gas cavity. Exceptional thermal insulation & soundproofing! The go-to for energy-efficient building windows and curtain walls. We provide Low-E coated tempered IGUs for enhanced energy savings.

Tempered Coated Glass (Solar Control / Low-E): Surface coating applied before tempering. Controls solar heat gain, reduces radiation, boosts energy efficiency. Key for high-performance building envelopes. Joy Shing Glass offers custom coating solutions.
