Float Glass Manufacture

SIGRAFINE profiles for tin bath walls

Float glass requires consistent high quality, absolute precision, flawless appearance, and the highest purity possible. Our materials and components for the continuous manufacture of large-format float glass are impressive in every respect.

SGL Carbon's portfolio is tailored to meet the demanding requirements and highly specific machinery used by float glass. In view of the high temperature of the tin bath of 1100°C (2000°F), a graphite edge insert is essential. The main reasons for using extruded graphite here are its high corrosion and abrasion resistance.

Our ash-reduced grades such as SIGRAFINE® R7550 have a particularly long service life, which helps keep plant maintenance costs to a minimum.
