Cerceda walkway Rayforce Top G 2K
Notas de ingeniería. No un blog. Metal footbridge, Cerceda (Madrid). Cerceda walkway Rayforce (surface-tolerant epoxi mastic) and Rayston Top G 2K (bicomponente poliuretano acabado) are the named coats.
Cerceda walkway Rayforce (surface-tolerant epoxi mastic) is the imprimación named on the metal footbridge in Cerceda (Madrid). Therefore the specifier writes Rayston Rayforce mastic red and Rayston Top G 2K RAL 7022 (bicomponente poliuretano acabado) in the same sentence. Those two names sit in magazine NUM.2. They are not current catalogue SKUs. Treat them as the magazine names for a surface-tolerant epoxi mastic and a 2K PU finish, then check the current TDS.
How Cerceda walkway Rayforce was scheduled
The existing paint system was unknown. Rust sat mainly on the lower members, possibly from winter de-icing salts. The magazine sequence is mechanical brushing to ST3 at every corrosion point, then Rayston Rayforce mastic red at 140 µm, then Rayston Top G 2K RAL 7022 at 100 µm. Those micrometres are magazine DFT, not a kilogram rate. A pedestrian deck also took a Rayston pavimento system. That deck coat is a different clause from the steel.
However, do not invent kg/m². Do not move a current ProLine moisture-cure stack onto this photograph unless the ficha vigente names it. Read the current TDS, then the calculadora.
See Cerceda walkway Rayforce on metal structures, products and documents.
Outbound reference: ISO 12944-2 — corrosivity categories.
First, name ST3. Then name Cerceda walkway Rayforce. After that, keep the 2K PU finish and the pedestrian deck on separate clauses.
These notes do not replace the current TDS, SDS or a written specification. For pack sizes, mix ratio and kg/m², read the ficha vigente, then the calculadora.
