Material Basics
Galvanized steel and stainless steel are popular materials for hardware. Each type has unique features and uses. Understanding their basics helps choose the right one.
Both materials resist rust but in different ways. Their composition affects strength, durability, and cost.
Galvanized Steel Composition
Galvanized steel is regular steel coated with zinc. The zinc layer protects steel from rust. This coating forms a barrier against moisture and air.
The base steel is usually carbon steel. The zinc is applied by dipping the steel in molten zinc or by electroplating. This process adds corrosion resistance.
- Core material: Carbon steel
- Coating: Zinc layer
- Protection: Prevents rust by blocking moisture
- Common methods: Hot-dip galvanizing, electroplating
Stainless Steel Grades
Stainless steel contains iron, chromium, and other metals. Chromium adds rust resistance by creating a thin, invisible layer on the surface.
There are many grades of stainless steel. Each grade has different amounts of metals, which change its strength and resistance to corrosion.
- Type 304: Most common, good corrosion resistance
- Type 316: Better for salty or harsh environments
- Type 430: Less expensive, magnetic, lower corrosion resistance
Corrosion Resistance
Corrosion resistance is key for hardware durability. It helps metal parts last longer outdoors.
Galvanized steel and stainless steel resist corrosion differently. Understanding these methods helps you choose the right hardware.
Galvanized Steel Protection
Galvanized steel has a zinc coating. This layer blocks moisture and air from reaching the steel.
If the surface gets scratched, zinc still protects the steel by corroding first. This is called sacrificial protection.
- Zinc coating prevents rust on steel
- Protects even if scratched
- Best for outdoor use in mild environments
Stainless Steel Rust Prevention
Stainless steel contains chromium. This metal forms a thin, invisible layer that stops rust.
This layer repairs itself if damaged. Stainless steel works well in harsh or wet conditions.
