2205 stainless steel and 316 stainless steel are both common stainless steel alloys, they have some differences when making Glass railings and handrails, mainly in the following aspects:
-
Corrosion resistance:
316 Stainless Steel: 316 stainless steel has good corrosion resistance, especially suitable for general corrosive environments, such as seawater, chemicals and so on. It has high resistance to chloride corrosion, but corrosion may occur under certain extreme corrosive conditions.
Stainless Steel 2205: 2205 Duplex Stainless Steel is a duplex stainless steel with excellent corrosion resistance and is particularly suitable for wet, salt water and marine environments, as well as high chloride concentrations. It has a higher resistance to corrosion and is therefore more durable in corrosive environments.
-
Strength and durability:
316 Stainless Steel: 316 stainless steel has a high level of durability, but it is less strong compared to 2205 stainless steel. This means that railings made with 316 stainless steel may require more bracing and crossbars to meet structural requirements.
2205 Stainless Steel: 2205 Duplex Stainless Steel has higher strength and durability relative to 316 Stainless Steel, so stronger railings can be made to support larger loads.
-
Appearance and Design:
316 Stainless Steel: There is not much difference in appearance between 316 stainless steel and 2205 stainless steel. They can both be used to create modern, clean and stylish Glass handrails and railings that provide a clear view.
2205 Stainless Steel: Due to its superior corrosion resistance, 2205 stainless steel is often better suited for use in corrosive environments and is therefore preferred in these environments.
-
Cost:
Generally speaking, 316 stainless steel is more economical compared to 2205 stainless steel because of the latter's higher alloy composition and properties.
In summary, the choice of 316 stainless steel or 2205 duplex stainless steel for Glass handrails and railings should depend on the specific application, structural requirements and budget. If the balustrade will be placed in a corrosive environment or requires higher strength and durability, then 2205 stainless steel may be a better choice. However, if budget is limited and corrosion is not an issue, then 316 stainless steel is also a viable option.
