Architectural glass comes in three different strength categories :

Annealed glass,  Heat-strengthened glass and Fully-tempered glass.

Annealed glass is the most commonly used architectural glass. It has good surface flatness because it is not heat-treated and therefore not subject to distortion typically produced during glass tempering. On the downside, annealed glass breaks into sharp, dangerous shards. Heat-strengthened and fully-tempered glass are heat-treated glass products, heated and quenched in such a way to create residual surface compression in the glass. The surface compression gives the glass generally higher resistance to breakage than annealed glass.

Heat-strengthened glass has at least twice the strength and resistance to breakage from wind loads or thermal stresses comparing to annealed glass. The necessary heat treatment generally results in some distortion compared to annealed glass. Like annealed glass, heat-strengthened glass can break into large shards.

Tempered glass is a heat toughened safety glass. It has undergone a special heat treatment to increase its strength and resistance to impact. In fact, tempered glass is approximately five times more resistant than normal glass. As an example, a piece of 8mm tempered glass will be able to withstand a steel ball weighing 500g dropped from a height of 2 meters.

Features:

1. 5 times harder than ordinary float glass, stronger resistance to thermal breakage than annealed or heat strengthened glass.
2. Once breakage occurs, the glass disintegrates into small cubical fragments, which are relatively harmless to human body.
3. It withstands abrupt temperature change of 220 Centigrade.
4. Sizes are produced as per customer request. Once tempered, it can not be cut down.

Usage: Window glass; Door glass; Curtain wall glass; Fencing glass in buildings, hotels, etc.

Fully-tempered glass (toughened glass) 

Provides at least four times the strength of annealed glass, which gives it superior resistance to glass break- age. It is float or plate glass that has been heated and rapidly cooled, increasing its inher- ent strength and ductility. Similar to heat-strengthened glass, the heat-treatment generally results in some distortion. If it breaks, fully-tempered glass breaks into many small frag- ments, which makes it suitable as safety glazing under certain conditions. It is used for windows that are exposed to high wind pressure or extreme heat or cold.

Clear Float Glass High quality glass

Clear Float Glass is superior in quality when compared to other flat glass and has the unique characteristics of excellent surface finishing, flatness, uniform thickness, high optical quality and bright appearance. The float process was developed in the late 1950's. Float technology has been rapidly replacing plate and sheet facilities worldwide in recent decades. Float glass derives it name from the Float process used where using the latest glass-making technology, heating mountains of silica sand and other raw materials to a liquid state and floating it on a bath of molten tin to produce a perfect ribbon of glass.

Clear float glass has high light transmission, optical clarity and ability to be fabricated to meet custom needs for performance and aesthetics. It can be toughened or laminated for safety glazing or silvered to produce mirrors. It is suitable for screen-printing, acid etching and decoration with ceramic materials.

Clear Float Glass is available in thickness range of 2 mm through 25 mm.

Characteristics of Clear Float Glass

• High light transmission
• Optical clarity
• Can be further fabricated into reflective, low-E, laminated, security, insulating, heat-treated and ceramic decorated glass
  
  

Application of Clear Float Glass

• Automotive Glass
• Reflective Glass
• Coated Glass
• Windows
• Mirrors
• Table Tops
• Insulated Glass
• Architectural Purposes

Clear Sheet Glass

Sheet glass also called Glaverbel glass, plate glass, it is made by mix high-quality sand, soda ash, dolomite and other chemical materials into glass furnace by a high temperature, take in turn through flat drawn, forming, anneal, cut and packing finish, clear sheet glass have high quality and competitive prices, pristine surface, natural daylight, high light transmittance(88%) and uniform thickness. Multiple processing options: may be be tempered, laminated,polished edge and so on. Multiple applications: ideal for furniture(cupboard, lamp, photo frame, welding glass lens), building(windows ,greenhouse,....)

• Clear sheet glass
• Glaverbel Glass With Edge Polished
• Photo frame glass
• Clear welding glass

UltraClear

Build with crystal clarity

UltraClear low-iron glass gives architects unprecedented control over light. It virtually eliminates the greenish cast associated with traditional glass—for an ice blue edge and clearly stunning results.

Accentuate the structure and color of your surroundings

UltraClear provides outstanding light transmission and clarity that makes any application with special decorative or structural elements more vivid and true. Standard glass can distort any light color. The neutral color of UltraClear eliminates this concern. All that is left is form and light. The result is unparalleled beauty and performance in doors, walls and wall coverings, railings, bath/shower enclosures, retail displays and fixtures, elevators and escalators, mirrors, furniture and case goods, floors and stairways, surfaces and tables.

Advanced technology for Ultra Clear Glass 
The low-iron glass increases light transmission and neutralizes the green color of standard glass leaving a crystal clear appearance. Tight tolerances provide minimal edge color variation across various cut sizes and glass thicknesses.

Applications
UltraClear can be fabricated, laminated, painted, cut and tempered just like ordinary float glass.

Clear thick glass

Is nearly colorless, and has a green or blue/green edge. It is typically made in thicknesses ranging from 3/32" to 3/4". Clear 1/4" thick glass will allow about 90% of visible light to pass through and will reflect about 8% of visible light. When looking through the glass, as the glass gets thicker the faint green color becomes more noticeable and light transmittance drops.
