Our ASTM A924 Compliant Galvanized Steel Coils adhere to the “Standard Specification for General Requirements for Steel Sheet, Metallic-Coated by the Hot-Dip Process.”
While specific standards like ASTM A653 or A792 define the coating type, ASTM A924 is the critical quality benchmark that governs the mechanical precision, dimensional tolerances, and testing protocols for all our metallic-coated products. By strictly following ASTM A924/A924M
Bomis Steel ensures that every coil delivered meets the highest global expectations for consistency and reliability.
Following the ASTM A924 general requirements, every batch of our steel undergoes a rigorous series of standardized tests to ensure compliance:
Mechanical Property Testing: Verification of yield strength, tensile strength, and elongation (as required by the specific base metal grade).
Coating Weight Verification: Utilizing the Triple-Spot Test or Single-Spot Test to ensure the zinc or aluzinc coating is evenly distributed and meets the specified designation (e.g., G90 or AZ150).
Bend Test Performance: Ensuring the metallic coating maintains a metallurgical bond with the steel substrate without flaking or cracking during fabrication.
ASTM A924 also regulates the general surface conditions and treatments available to prevent storage stains and enhance longevity:
Chemical Passivation: Application of chromate or chrome-free treatments to inhibit “white rust.”
Oiling & Dry Conditions: Customizable surface oiling to match your specific lubrication requirements for stamping or forming.
Spangle Appearance: Precise control over regular, minimized, or zero spangle finishes as per the end-user’s aesthetic and painting needs.

1.What is the difference between ASTM A653 and ASTM A924?
ASTM A924 covers the general requirements (tolerances, testing, and dimensions) for hot-dip galvanized steel, while ASTM A653 specifies the material qualities (commercial, drawing, structural). They are usually cited together.
2.What dimensions are available for A924 compliant coils?
We provide ASTM A924 coils in thicknesses from 0.12mm to 4.0mm and widths up to 1500mm, all meeting strict dimensional tolerance standards.
3.Are you a manufacturer or a trading company?
Біз сату бойынша 10 жылдан астам тәжірибесі бар зауытпыз.
4.How do you guarantee the quality?
