What if a large steel structure exceeds the galvanizing kettle size? K.C.F. offers 13-meter hot-dip galvanizing equipment. Learn about size limits, double dipping, hanging and hole design for H-beams, bridge members and factory steel structures. Send us your drawings for a processing evaluation.
A complete introduction to hot-dip galvanizing principles, manufacturing process and steel corrosion protection, from surface pre-treatment, pickling, fluxing and dipping to quality inspection, plus FAQs on pre-galvanizing preparation, vent and drain holes, workpiece design, coating thickness and bright vs. gray finishes.
Why are some hot-dip galvanized surfaces bright silver while others are gray? Learn what causes bright and gray finishes, how steel composition, coating structure and process conditions affect appearance, and why brightness alone can't be used to judge galvanizing quality.
How do you choose the right grating? From pedestrian, vehicle and industrial platform uses to load, support span, bearing bars, grating spacing, serrated anti-slip surfaces, hot-dip galvanizing and installation, this guide covers the key points of steel grating selection so you don't choose the wrong specification by looking at size alone.
Why do hollow components need holes before hot-dip galvanizing? A complete look at how vent and drain holes affect process safety, the flow of pre-treatment solutions and molten zinc, internal and external coating and finished quality, plus key hole design points to check before sending steel for galvanizing.
