Hot-Dip Galvanizing

What is Hot-Dip Galvanizing?

Hot-dip galvanizing is a process used to protect steel and iron from corrosion. This is achieved by immersing the metal parts in a bath of molten zinc. It is widely used in various industries, including construction, automotive, agriculture, and marine, for products such as structural beams, piping, fences, and fasteners. It is particularly valued for its ability to provide long-lasting protection in harsh environments.

How we galvanize

Watch a batch of bolts journey from plain finish to hot-dip galvanized in this video that describes the process. After that, discover how our process is tailor-made for the construction fastener industry.

Specialized for threaded fasteners

Galvanizing threaded parts requires a specially designed galvanizing line. General-purpose galvanizers will leave excess zinc in the threads, preventing a nut from threading onto the fastener. Portland Bolt’s specialized galvanizing line will:

  • Produce parts faster
  • Ensure clean threads for proper nut fit

Portland Bolt galvanizes threaded fasteners all day, every day in our 12′ long x 4′ wide x 7′ deep zinc tank. Our expertise, specialized galvanizing line, and inspection processes ensure fast delivery times, clean threads, and trouble-free nut fit.

Galvanizing offers an exceptional corrosion-resistant zinc coating for steel fasteners. The process provides durability, and long service life, and is economical when compared to other coating options. Portland Bolt’s unique system is developed specifically for threaded fasteners ensuring quality threads and a trouble-free nut fit.

  • Hot-dip galvanizing offers long-term protection for fasteners and other steel products.
  • Parts are evenly coated for complete coverage.
  • Expected service life can exceed 30 years.
  • Low life-cycle cost makes galvanizing an economical method of protecting steel.
  • Zinc bonds metallurgically to steel providing permanent protection.
