Ensuring the quality of heat-treated glass is a constant challenge for manufacturers. Roller-wave distortion and edge lift are common issues that can lead to visible imperfections and complications during assembly in laminated or insulated units. Recognizing this, Glaston developed the FlatGuard Roller Wave & Edge Lift Gauge, a compact and practical solution that brings precision directly to the production floor.

FlatGuard was born from real-world production challenges. Heat-treated glass can easily show roller-wave distortions – subtle undulations caused during the tempering process – and edge lift, where the edges of the glass slightly raise, affecting fit and finish. Traditional measurement methods often required separate tools or off-site testing, which slowed down production and left quality control gaps.

The FlatGuard combines both measurements in a single, 420 mm gauge designed for field use. Its durable construction ensures reliable performance, while the easy-to-use design allows operators to quickly evaluate glass flatness without specialized training. Hands-on testing refined the tool for precision and repeatability, ensuring results meet EN standard requirements.

By integrating practical design with robust measurement capabilities, Glaston’s FlatGuard delivers higher quality, greater confidence, and more efficient quality control. Manufacturers can now address roller-wave distortion and edge lift on-site, preventing defects before they reach assembly and guaranteeing consistently superior glass products.
