1 Scope

1.1 GB/T 30790 deals with the corrosion protection of steel structures by protective paint systems.

1.2 GB/T 30790 covers only the corrosion-protective function of paint systems. Other protective functions are not covered by GB/T 30790, such as:

— microorganisms (marine fouling, bacteria, fungi, etc.);

— chemicals (acids, alkalis, organic solvents, gases, etc.);

— mechanical action (abrasion, etc.);

— fire.

1.3 The field of application is characterized by:

— the type of structure;

— the type of surface and surface preparation;

— the type of environment;

— the type of protective paint system;

— the type of work;

— the durability of the protective paint system.

Although GB/T 30790 does not cover all types of structure, surface and surface preparation, it may, by agreement, also be applied to those cases which are not covered by the standard.

The various aspects of the field of application are described in more detail in 1.3.1 to 1.3.6.

1.3.1 Type of structure

GB/T 30790 concerns structures made of carbon or low-alloy steel (e.g. in accordance with EN 10025-2) of not less than 3 mm thickness, which are designed using an approved strength calculation.

Not covered by GB/T 30790 are concrete structures reinforced with steel.
