rayonnage cornièrerayonnage bord tombérayonnage taquetrayonnage grugeage

This grating is particularly suitable for shelving with reduced-width shelves. Load absorption will be limited.

This grating is suitable for various types of shelving and offers numerous advantages, the most important of which is its cost of manufacture. The butt joint between the two edges provides greater load absorption and safety, and the flanged edge locks the grating in place on the racks.

This grating offers good adherence and stability thanks to the contact between the lips on the underside and the racks.

The butt joint between the two edges provides greater load absorption and the flanged edge provides safety.
