KILN FURNITURE

Wide variety of shapes and sizes of pieces made by extrusion, casting and pressing.

With a careful approach, the edges of low thermal mass products are specially designed by the engineering office for each application guaranteeing the kiln efficiency and its firing profiles.

All plates are made by extrusion which provides excellent surface finishing and strictly controlled dimensional tolerances.

WELDING SUPPORTS

The efficiency and durability of the RPA welding supports provide superior working performance ensuring time saving and welding reliability./p>

The supports are produced according to the needs of each user in RPA-MC-17 compositions.
