Siti-B&T launches Lastra

Siti-B&T Group is introducing Lastra, a new brand name that will be used for extremely large-format products (1200x2400 mm and 1500x3000 mm). On display at Tecnargilla, the innovation is based on Grestream technology, which now delivers outstanding results following years of constant development. It is a complete technological process, from raw materials preparation through to packaging, and is capable of extruding extremely large format porcelain sheets for which conventional powder pressing technology is not normally used.

The line consists of various stages and applications using a number of machines and exploits the technological expertise in body formulation, decoration systems and drying and firing processes acquired by Siti B&T Group in its many years of experience in the world's markets. Grestream plants are already in operation in Germany (where two lines have been supplied to the company Petraluxe, which produces large-format sheets for applications ranging from ventilated facades to kitchen countertops) and in Iran (where a line has been supplied to Hafez Tile Ceramics Industries for the production of floor tiles and ventilated facades).

The production process has given excellent results in terms of the geometry of individual pieces, above all flatness, with performance levels well above expectations. Another important aspect is that of the mechanical and physical characteristics of the product, which is extraordinarily strong due to the high degree of compaction during the plastic shaping process. The third essential aspect is decoration, which combines the decorative capabilities of digital machines with the unique characteristics of Grestream.
