Hot-Dip Galvanizing
In order to better serve our customers, Valley Nut and Bolt offers in house own hot-dip galvanizing service. Located between Seattle and Portland, our 12,000 square foot facility provides high-quality, fast, reliable and local hot dip galvanizing service. We support our galvanizing customers by providing full pick-up and delivery service.
Two Galvanizing Standards
ASTM A123
ASTM A123 is the standard specification for hot-dip galvanizing on iron and steel products, ensuring a uniform, corrosion-resistant zinc coating applied after fabrication. This process involves immersing steel components into a bath of molten zinc, which metallurgically bonds to the base metal, forming a protective layer that resists rust and extends product lifespan even in harsh environments. ASTM A123 covers coating thickness, appearance, finish, and adherence for a wide range of structural shapes and assemblies. It is commonly used in construction, transportation, utilities, and industrial applications where long-term corrosion protection and low maintenance are critical.
ASTM A153
ASTM A153 is the standard specification for zinc coating (hot-dip) on iron and steel hardware, typically applied to fasteners, castings, and small components after fabrication. Unlike ASTM A123, which covers larger structural elements, A153 is tailored for smaller parts that require individual handling or are processed in batches using baskets or racks. The hot-dip galvanizing process forms a metallurgically bonded zinc coating that provides durable, long-lasting corrosion protection. ASTM A153 is widely used for hardware in construction, utilities, and infrastructure projects where reliable, maintenance-free performance in outdoor or corrosive environments is essential.

Our Hot Dip Galvanizing Process
At our facility in Olympia, WA, we follow a meticulous process to ensure high-quality results. We start with thorough preparation, cleaning the steel to remove impurities for optimal adhesion.
During the galvanizing stage, steel is immersed in molten zinc, creating a robust protective coating. Our state-of-the-art technology ensures consistency and quality.
Quality control is paramount, with rigorous testing and inspections to meet the highest standards. Safety is also a priority, with strict measures in place to protect our team and your products.
Benefits of Hot Dip Galvanizing
- Corrosion Resistance:
Hot dip galvanizing provides a robust zinc coating that shields steel from rust and environmental damage. This protection is crucial in areas with high moisture levels, ensuring longevity and reliability. - Longevity and Durability:
Galvanized steel is designed to endure for decades, resisting wear and tear. This durability reduces the need for frequent repairs or replacements, making it an ideal choice for long-term applications. - Cost-Effectiveness:
While the initial investment may be higher, the reduced maintenance and extended lifespan of galvanized steel result in significant cost savings over time. This makes it a smart investment for businesses looking to optimize their resources. - Sustainability:
As an environmentally friendly process, hot-dip galvanizing contributes to sustainability. Galvanized steel is fully recyclable, reducing waste and supporting eco-friendly practices in construction and manufacturing.
Industries and Applications
- Construction:
In the construction industry, galvanized steel is essential for creating resilient buildings, bridges, and infrastructure. Its strength and corrosion resistance ensure that structures remain safe and stable over time, even in challenging environments. - Automotive:
The automotive sector benefits from galvanized steel through the production of corrosion-resistant parts. This enhances the longevity and performance of vehicles, providing consumers with reliable and durable options. - Agriculture:
Galvanized steel is used extensively in agriculture for machinery, fencing, and storage structures. Its ability to withstand harsh weather conditions ensures that agricultural operations run smoothly and efficiently. - Energy:
In the energy sector, especially in power and renewable energy projects, galvanized components offer durability and sustainability. This reliability is crucial for maintaining infrastructure that supports energy production and distribution.
What is the lifespan of galvanized steel?
Galvanized steel can last for decades, even in the moist climates typical of the Pacific Northwest.
How does galvanizing compare to other coatings?
It offers a more durable and long-lasting protective layer than paint or powder coating.
Can galvanized steel be painted?
Yes, with proper surface preparation, paint can adhere effectively.
Is hot dip galvanizing environmentally friendly?
Yes, the process is eco-friendly, and the steel is fully recyclable.
