With this project, the question was whether A2 stainless steel would be sufficient for the brackets or whether A4 was required. However, as the Atlantic Ocean is quite a distance from the house and the salt content in the air was therefore not as high as initially assumed, the decision was made to use the sturdy but more economical “Classic” cable brackets, which are made of A2 stainless steel. In fact, there were no problems with rust or corrosion.
