Exterior steel structures


Tikkurila provides a wide range of industrial paints and coating for construction steel works supplying materials and systems that comply with ISO 12944, a global corrosion protection standard. Part 5 of this standard determines protective coatings systems for different corrosive environments: C2, C3, C4, C5-I and C5-M. The standard also determines durability ranges, which have an impact on the time to the first major maintenance round as follows:
High Durability (H) > 15-years design life
Medium Durability (M) 5–15 years of design life
Low Durability (L) < 5-years design life.

Some of Tikkurila coating systems also comply with the Norwegian NORSOK standards. The requirements underlying the NORSOK standard for protective paint systems are known to be among the most demanding on the market. NORSOK tests are performed in accordance with the ISO 20340 standard.

Tikkurila paint and coating systems for new construction and maintenance of steel surfaces are developed for conditions that vary from mild to heavy stress.
