Bulletproof Glass

Bulletproof safety glass for resistance against bullet penetration and ballistic attack
Bulletproof Glass

Bulletproof glass is a high-security specialty glass designed to withstand certain levels of bomb explosions or bullet impacts without shattering or detaching from its frame. It maintains its integrity or non-penetrating destruction even under ballistic attack. In addition to having the optical properties of regular glass, bullet-resistant glass provides strong protection against gunfire, minimizing direct harm to individuals during bullet attacks or accidental explosions. It also helps reduce repair costs for facilities surrounding the explosion site or attack, making it widely used in protecting highly classified government facilities, cultural heritage preservation, bank security, and valuable property protection.

Ballistic Glass Principles and Structure

The ballistic glass works by utilizing the elastic potential energy of the glass and the surface energy of glass fragments. When a high-speed bullet strikes the bullet-resistant glass, the point of impact causes the glass to crack, forming radial cracks. The bullet deforms, and its kinetic energy (impact force) is absorbed and reduced, preventing it from penetrating the glass. The glass fragments are adhered together by an organic membrane, minimizing the risk of injury from flying debris.

The bullet-resistant glass is mainly composed of multiple layers of transparent organic materials and varying thicknesses of transparent glass, bonded through a specialized process. The general structure consists of three main layers:

  • Support Layer: Located in the first and third layers, typically made of transparent float glass with a specific thickness and strength. This layer absorbs the initial impact, breaking the glass and deforming the bullet, thus slowing or stopping its movement.
  • Transition Layer: Positioned in the second and fourth layers, this layer is made of transparent organic materials with strong adhesion and light stability. It bonds the other layers into a cohesive structure, absorbing part of the bullet's impact, altering its direction, and providing resistance against shock, explosions, and vibration.
  • Safety Protection Layer: The fifth layer typically consists of high-strength glass or high-strength transparent organic materials, which offer excellent elasticity and toughness. This layer absorbs the majority of the impact force, preventing the bullet from passing through and embedding the bullet within the layer.

Frequently Asked Questions

What ballistic standards does your bulletproof glass meet?

Our bulletproof glass can withstand F54 Handgun / 7.62mm NATO Round, F56 Submachine Gun / 7.62mm Steel Core Round, F79 Light Submachine Gun / 7.62mm Steel Core Round, and F53 Sniper Rifle / 7.62mm Steel Core Round.

Can you provide bullet-resistant glass with tint, anti-uv, or low-e coatings?

Yes, we can provide bullet-resistant glass and offer additional features such as tint, anti-UV coatings, or low-E coatings to enhance both the functionality and aesthetic appeal of the glass.

How is the bulletproof glass packaged and transported internationally?

Bulletproof glass is typically packaged in sturdy wooden frames or wooden crates. This type of packaging prevents the glass from being impacted, compressed, or scratched during transit, ensuring the glass remains intact and undamaged.

What is the expected service life of your bulletproof glass?

The service life of bulletproof glass generally depends on factors such as materials, environmental conditions, maintenance, and usage intensity. Typically, the expected service life ranges from 15 to 30 years, but this can vary based on the specific circumstances.
