High-Tensile Flat & Slab-Cutting Blades

In the modern concrete roof tile industry, the straight cut is the signature of architectural excellence. Whether you are producing a minimalist flat tile in Europe or a high-volume shake or slate profile in the United States, the quality of that cut defines the final roofline. At WELSCH, we provide specialized spring-steel flat blades engineered for absolute geometric stability across the entire 300 mm (12 in) ribbon.

Because a straight cut leaves no room for error, our blades are designed with a critical metallurgical duality: they are thin enough to slice without dragging the concrete, yet tough enough to remain perfectly linear under the massive inertia of high-speed production. We offer spring steel flat blades in a precision range from 0.8 to 1.5 mm (21 to 16-gauge), allowing you to optimize the displacement of the concrete during the cut.

Our spring steel blades are heat-treated to breathe with the machine. Unlike brittle tool steels, they absorb the high-frequency vibrations of 150+ TPM lines and instantly return to true, preventing the bowing or wandering that ruins a flat tile's profile. Every blade is double-ground to a razor finish, reducing edge-drag and ensuring a perfectly vertical 90-degree face.

For the European market, our 0.8 mm blades provide the surgical accuracy required for modern minimalist flat tiles. In high-speed double-cut systems, our flat blade acts as the first-cut specialist, cleanly severing the concrete ribbon before the round-nose knife forms the final profile, eliminating nose-slump and significantly extending the life of 3D-forming knives. For the North American market, our 1 mm blades are the industry benchmark for producing the slab-cut look essential for high-end wood-shake and slate imitations.
