Avoiding Distortion During Hot Dip Galvanizing Galco Hot

Where an article can not be single dipped due to its size consider splicing the structure so that it can be dipped as two separate parts, each being single dipped. The pieces may then be joined by bolting or welding after galvanizing. Where possible, consideration might be given to stress relieving an article prior to hot dip galvanizing Design Guide for Hot Dip best practice for venting and Design Guide for Hot Dip Galvanizing best practice for venting and draining. Hot Rolled Sections End plates, gussets and stiffeners all restrict drainage. Vent and drain holes or openings (e.g. snipes) need to be provided in the corners of connected structural member (Figure 9 and Figure 10). The corners of end plates, gussets and
