ProLine AB85H steel on an exposed airport structure
Notas de ingeniería. No un blog. ProLine AB85H steel is a hybrid poliurea anti-corrosion coat. It is not C5H zinc-MIO and not CH55.
Specify ProLine AB85H steel when the metal is exposed and already corroding. Krypton magazine NUM.5 (October 2025) names the Integrated Services Centre for Strategic Airport Development in Málaga at 1,000 m². Therefore the specifier writes a hybrid poliurea anti-corrosion system, not a zinc-MIO C5H card.
What ProLine AB85H steel actually uses
NUM.5 prints Krypton ProLine PU AL Imprimación (aluminium poliuretano imprimación) plus Krypton ProLine AB85H. The magazine calls AB85H a hybrid poliurea with anti-corrosion properties plus abrasion and impact resistance, after the surface is cleaned. Catalogue 2024 lists AB85H in the abrasion-and-impact poliurea group. Keep that chemistry on this name.
This is not ProLine C5H steel (PU ZN Imprimación + AC MIO + PU 1000 TC). This is not AB95 P, which NUM.4 uses on a Gran Canaria warehouse with PU AL Imprimación and PU 1000 TC. Do not collapse the ProLine letters. An airport photograph is not a pipe lining.
However, a ribbed metal finish is not a thickness. Read build from the current TDS. Also, do not invent kg/m².
Cómo redactar ProLine AB85H steel
First, name exposed steel and the corrosion condition. Then name PU AL Imprimación and AB85H in one clause. After that, send surface preparation to the ficha vigente. In addition, size the area on the calculadora.
See Krypton ProLine AB85H, Krypton ProLine PU AL Imprimación, metal structures and engineering, and documents. Area: calculadora.
Outbound reference: ISO 12944.
A corrugated sheet is not a roof membrana. Keep ProLine AB85H steel on the protective chapter.
Therefore mix ratio stays on the sheet. First name the imprimación. Next name AB85H. After that open documents. Also keep C5H off this clause.
Cleaned steel still needs the named coats. Keep ProLine AB85H steel on the hybrid the magazine names. Then read the sheet.
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.
