1 Scope

GB/T 30790 in this section describes the type of paint and coating systems for corrosion protection of steel structures. This section also provides a suitable for different environments (GB/T 30790.2), different surface treatments Ratings (GB/T 30790.4) and expected durability rating (GB/T 30790.1) Selection Guide of the coating system. The durability of the coating system is divided into low, medium, and high class.
