Technical Standard EN 10327: Requirements for Hot-Dip Galvanized Steel
The EN 10327 standard establishes current technical requirements for low-carbon steel sheet and strip products subjected to continuous hot-dip galvanizing and intended for complex cold forming. It is important to note that this regulatory document has been updated and replaced by the EN 10346 standard, which EV Group China uses to ensure that products comply with modern international engineering protocols.
The hot-dip protective coating technology involves creating a durable barrier on the steel base surface using the following types of coatings:
- Pure zinc (Z);
- Zinc-iron alloy (ZF);
- Zinc-aluminum alloy (ZA);
- Aluminum-zinc alloy (AZ);
- Aluminum-silicon alloy (AS).
The typical thickness range of the finished product varies from 0.35 mm to 3.0 mm. EV Group China supplies steel products where thickness is defined as the total parameter of “steel + protective layer” after the hot-dip coating process is completed.
Application Areas and Supply Format
Products meeting these specifications are aimed at industries where the combination of high ductility during deep drawing and exceptional corrosion resistance is of key importance. EV Group China experts emphasize: the potential for corrosion protection is directly correlated with the density and mass of the applied metal layer.
The specification covers:
- Wide strip steel;
- Sheet blanks with a width of up to 2600 mm;
- Slit-to-width strip (slitted steel) with a width of less than 600 mm.
Upon individual request, EV Group China can supply steel with a thickness exceeding 3.0 mm. In such cases, technical parameters, including coating adhesion and forming performance indicators, are recorded in the specific order specification.
Exclusions from the Standard
This document does not apply to the following product categories:
- Hot-dip coated structural steels (regulated by EN 10326);
- Electrolytically galvanized cold-rolled steel (according to EN 10152);
- Continuously organic coated flat steel (EN 10169 series standards);
- High-strength steels for cold forming requiring special processing modes (according to EN 10292).
