Focus on Reinforcing Bar
Reval is the trade mark for the three most popular stainless steel grades of reinforcement bar manufactured by Acciaierie Valbruna S.p.A, these being:
- 1.4162 (Lean Duplex)
- 304 S31 (1.4301)
- 1.4362 (Lean Duplex)
- 316 S33 (1.4436)
- Duplex (1.4462)
The quality of the reinforcing bar produced under the Reval trade mark is a result of a very close co-operation between Acciaierie Valbruna and the European Academic world devoted to the problems of concrete structure durability within aggressive corrosion environments.
