GHB Certification

our promise to you

why standards matter

Designers wishing to specify HDG need only use two Standards; one covering the design and durability of HDG steel (AS/NZS 2312.2), and the other dealing with the manufacturing process and tolerances (AS/NZS 4680).

Galvanising Hawkes Bay complies with both standards and are certified in accordance with all required standards.

In addition, we are members of the Galvanising Association of New Zealand.
