Float Glass

Float glass, a type of flat glass produced through the "float" process, is known for its uniform thickness and smooth flatness. Its outstanding properties make it the most widely used base material in the glass industry. Whether in construction, interior decoration, or the automotive sector, float glass holds a leading position across various applications.

Raw Material and Melting: The main raw materials for producing float glass include silica sand, soda ash, feldspar, and dolomite, which are mixed in a specific ratio and heated in a furnace at 1600℃ to form molten glass.

Float Process: Then the molten glass is poured onto a tin bath, where it spreads and forms a smooth sheet on the surface of molten tin.

Annealing: After being gradually cooled and annealed, the float glass sheets are fully formed.

According to color, float glass can be divided into clear float glass, ultra clear float glass (low iron float glass) and tinted glass.

According to quality, float glass can be divided into the level of Q1(none for visible bubbles, distortions, or blemishes), Q2(has little numbers of bubbles, distortions, or blemishes) and Q3(there are obvious bubbles and other blemishes).

Smooth and Flat Surface: The float process ensures the glass has a high degree of flatness and smoothness.

Physical Strength: This type of glass has better physical strength than sheet glass, which can significantly reduce the risk of breakage during transportation.

Uniform Thickness: Float glass maintains a consistent thickness throughout, meeting the needs of various applications.

High Transparency: Float glass, known for its excellent optical properties and high light transmission, delivers exceptional clarity. In particular, ultra clear float glass typically achieves a light transmittance of over 91.5%.

Low Cost: The production process of float glass has the advantages of continuity, high automation, high material utilization rate and relatively low energy consumption, making its cost significantly lower than that of sheet glass in large-scale production.

As an excellent basic material, float glass is widely used in industries such as construction, decoration, automobiles, home appliance panels and solar glass due to its advantages of high quality, low cost and large production capacity.

Glass Curtain Wall: Float glass is processed into coated glass or tinted glass, which is often used in the curtain wall of commercial high-rise buildings, such as large office buildings, hotels, etc.

Glass Windows and Doors: In modern building design, float glass is widely used across almost every structure. For many street-side shops, glass doors and windows are commonly chosen to enhance visibility, showcasing the store’s interior layout and products more effectively. In residential homes, processed float glass is typically utilized, such as insulated glass units (IGUs) for better thermal insulation, frosted glass for an elegant decorative touch, and tempered glass for enhanced safety.

Automotive Glass: Automotive glass usually chooses Q1 grade high-quality float glass, which is tempered and laminated to give it strong impact resistance and shatter proof properties, fully ensuring the safety of drivers and passengers.

Mirror Glass: The mirror is crafted from premium float glass, ensuring a clear, undistorted image with excellent reflective quality.

Furniture and Appliances Panels: Through further processing of float glass, we can produce back-painted glass, frosted glass, ceramic fritted glass, and other types of glass suitable for use in furniture and appliance panels.
