Piro-S - Steel
Pirobouw has also been a manufacturer of fire-resistant spray plasters, Piro-S and Piro-C, since the early years.
Piro-S(teel) is a spray plaster with excellent fire-resistant performance suitable for the protection of steel, for both renovation and new construction projects.
Piro-S can be installed by virtually anyone using traditional spray equipment. It is important that the required thickness be respected. The fire-resistant plaster consists of a fibre-free composition of vermiculite, perlite and aggregates with gypsum as a binder. This composition results in a high fire-resistant value and guarantees excellent mechanical strength. Unlike some other fire-resistant plasters, the plasters remain hard and durable after curing, so they do not pulverize over time. The plasters can be painted after they are placed.
