Galvanized Profiles

In China, the standards for galvanized profiles are primarily established and maintained by the Chinese National Standards (GB/T) and the Ministry of Housing and Urban-Rural Development (MOHURD). These standards ensure the quality, safety, and performance of galvanized steel profiles used in various construction and engineering applications.

The most relevant Chinese National Standards related to galvanized profiles include:

GB/T 2518-2019: Continuous hot-dip galvanized steel sheets and strips. This standard specifies the requirements for continuous hot-dip galvanized steel sheets and strips, which can be used for manufacturing galvanized profiles.

GB/T 12754-2019: Prepainted galvanized steel coils. Although this standard is primarily for prepainted galvanized steel coils, it covers the general requirements for galvanized coatings and can be relevant to certain galvanized profiles.

GB/T 3091: Welded steel pipes for low-pressure liquid delivery. This standard specifies the technical requirements for welded steel pipes used for low-pressure liquid delivery, which can include certain types of galvanized profiles used in similar applications.

GB 50018: Code for Design of Steel Structures. This code provides guidance on the design of various steel structures, including those involving galvanized profiles.


In the United States, the standards for galvanized profiles are primarily established and maintained by the American Society for Testing and Materials (ASTM) and the American Iron and Steel Institute (AISI). These organizations set the specifications and guidelines for various galvanized steel products, including profiles, to ensure quality, consistency, and safety.

The most relevant ASTM and AISI standards related to galvanized profiles include:

ASTM A123 / A123M: Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products. This specification covers the requirements for hot-dip galvanized coatings on various steel products, including profiles. It outlines the coating thickness, adherence, and other properties of the galvanized layer.

ASTM A653 / A653M: Standard Specification for Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy-Coated (Galvannealed) by the Hot-Dip Process. Although this standard is primarily for galvanized steel sheets, it covers the general requirements for hot-dip galvanizing, which can be relevant to galvanized profiles as well.

AISI S200 Series: North American Standard for Cold-Formed Steel Framing - General Provisions. This series of standards, developed by AISI, provides guidance on the design, fabrication, and installation of cold-formed steel framing, which can include galvanized profiles.

AISI S220: North American Standard for Cold-Formed Steel Framing - Nonstructural Members. This standard specifically addresses the requirements for nonstructural cold-formed steel framing members, including galvanized profiles used in non-load-bearing applications.

 

In the United Kingdom, the standards for galvanized profiles are primarily governed by the British Standards Institution (BSI). The BSI sets specifications and guidelines for various galvanized steel products, including profiles, to ensure quality, safety, and performance.

The most relevant BSI standards related to galvanized profiles include:

BS EN ISO 1461: Hot-dip galvanized coatings on fabricated iron and steel articles - Specifications and test methods. This standard specifies the requirements for hot-dip galvanized coatings on steel products, including profiles. It covers the minimum coating thickness, adhesion, appearance, and other properties of the galvanized layer.

BS EN 10326: Continuously hot-dip coated strip and sheet of structural steels - Technical delivery conditions. Although not specific to profiles, this standard provides technical delivery conditions for continuously hot-dip coated structural steel products, which can be relevant to galvanized profiles.

BS EN 1090-2: Execution of steel structures and aluminium structures - Part 2: Technical requirements for the execution of steel structures. This standard provides technical requirements for the execution of steel structures, including galvanized profiles, to ensure compliance with safety and quality regulations during construction.

 

In Japan, the standards for galvanized profiles are primarily established and maintained by the Japanese Industrial Standards (JIS). The JIS sets specifications and guidelines for various industrial products, including galvanized steel profiles, to ensure their quality, safety, and reliability.

The most relevant JIS standards related to galvanized profiles include:

JIS G 3302: Hot-dip zinc-coated steel sheets and coils. This standard specifies the requirements for hot-dip zinc-coated steel sheets and coils, which can be used for manufacturing various galvanized profiles.

JIS G 3303: Tinplate and blackplate. Although this standard is primarily for tinplate and blackplate, it also covers the general requirements for electrolytic zinc-coated steel sheets and coils, which can be relevant to certain types of galvanized profiles.

JIS G 3321: Hot-dip 55% aluminum-zinc alloy-coated steel sheets and coils. This standard specifies the requirements for hot-dip 55% aluminum-zinc alloy-coated steel sheets and coils, which may be used for certain galvanized profiles with an aluminum-zinc coating.

JIS G 3443: Coated steel pipes for water service. Although this standard is primarily for coated steel pipes used in water service, it can be relevant to galvanized profiles used in similar applications.
