Crystar® and Hexoloy® High-Load Beams

Engineered Ceramics Shapes

Saint-Gobain Performance Ceramics & Refractories’ high-load (HL) beams offer extreme high-loading capacity at elevated temperatures: 1 ton at 1,600°C / 3,000°F.

This trusted and reliable material technology delivers increased productivity for vertical firing assemblies while maximizing construction stability and fired product quality.

Customized design services are available to optimize high-load beams further to meet individual customer requirements.

Structural efficiencies in high-temperature applications
Minimum kiln furniture mass
Maximum strength
Increased automation compatibility for loading and unloading
