In our latest soundout episode our fixings/anchor expert Steve Grkinic discusses the role the environment plays when selecting an anchor/fixing.
When considering the environment we need to answer the following questions;
- Will the anchor be installed internally?
- Will the anchor be installed in humid conditions?
- Will the anchor be installed outside/external?
- Will the anchor be installed near the coast?
- Are there any special conditions which need considering?
Most internal applications will be zinc plated. For certain applications, for example, in a multi-story car park once we remove the walls the environment is altered. Certain applications such as swimming pools need very careful consideration as the chlorinated environment can induce stress corrosion cracking in some grades of stainless steel.
Below you can see a table that outlines a typical application and the average amount of time it would take for an anchor/fixings finish to damage*
*Please be aware in each of these cases we are presuming the application condition is normal before installation.
Overall, the environment is a very important factor to consider when selecting an anchor.
