Galvanized vs. Stainless Steel Bolts

Galvanized vs. Stainless Steel Bolts

When choosing hardware for specific applications or projects, understanding the common features and differences between stainless steel and galvanized bolts is important. We'll discuss their properties to ensure you're using the most suitable equipment, save time and money, and avoid trouble down the line.

Properties of Galvanized Bolts

Galvanized bolts are made of steel that undergo a special process called galvanization. This procedure involves coating the bolts with a protective layer of zinc to protect them from rust and corrosion. The galvanizing process will increase their longevity, making them an excellent choice for outdoor settings.

The zinc layer is used as a barrier, so even if the surface gets scratched, the underlying steel remains protected. A galvanized bolt will look grey in color and have a rougher texture to it. The key qualities of galvanized bolts include durability, excellent corrosion resistance, and comparatively lower cost. However, the zinc coating may wear off over time or under intense conditions and expose the underlying metal to corrosive elements.

Galvanized bolts are found in bridge construction, automotive uses, and home and commercial construction. They can also be used in decking, roofing, and marine applications.

Properties of Stainless Steel Bolts

In contrast, stainless steel bolts are made of chromium and nickel alloy materials in addition to other elements. Stainless steel has a higher luster than steel and is resistant to corrosion, thanks to the presence of chromium. It is used in countless applications and products. Stainless steel can be made into bars, wire, sheets, and tubing. It is a highly versatile metal found in cookware, autos, appliances, and surgical instruments.

Stainless steel in bolts has high durability, high tensile strength, excellent heat resistance, and remarkable corrosion resistance. Stainless steel bolts will maintain their integrity even under extreme temperatures, making them ideal for high-stress conditions and harsh environments.

Stainless steel bolts are costlier than galvanized bolts, but their greater resistance to corrosion makes them a worthy investment for applications exposed to corrosive chemicals or high temperatures. Stainless steel bolts are used in machinery, appliances, automobiles, aircraft, and medical equipment.

Galvanized Bolts vs. Stainless Steel Bolts

While both galvanized, and stainless steel bolts offer corrosion resistance, the difference lies in their level of durability and the environments in which they perform best.

Galvanized bolts are budget-friendly and provide solid corrosion resistance, making them ideal for outdoor construction projects and marine environments. However, the protective zinc layer may eventually wear off, particularly in harsher conditions.

On the other hand, stainless steel bolts provide superior corrosion resistance and can withstand high temperatures and corrosive chemicals. They're best suited for applications that require strength, durability, and long-term corrosion resistance. However, their superior qualities come with a higher price tag.

The best way to choose between the two should be based on the requirements of your project. In short: stainless steel bolts are a good choice for projects where corrosion resistance is of great importance. Galvanized bolts are good for when you need strength.
