Choose the right finish and avoid galvanic corrosion

For over three decades, our company has done its best to provide customers with high quality building materials. Steel fixings form part of the collection as well and are undoubtedly some of the most important components in the industry. Comprised of the finest materials and designed to last, ours are the products to depend on.

Steel fixtures might be small things, but mishandling them can result in some rather substantial consequences. To assist users in avoiding the mistakes people make whilst using them, we’ve put together a list of dos and don’ts.

One of the things you need to do is choose the proper surface finish. The more polished or smoother your finishes are, the greater the corrosion resistance. Certain products come with a satin, rough, or brushed finish, sometimes on downpipes, fittings, and hinges. These varieties of finishes are able to trap minuscule particles which can harm the steel’s chromium oxide layer such as salt. This causes what’s known as tea-staining and gives your metal a rusty aesthetic. This becomes worse if the steel isn’t exposed to rainwater, as it can wash the particles off.

Whatever you do, don’t cause galvanic corrosion. This is where two disparate substances encounter each other, react, and lead to rusting. This might be a possibility for certain other metals when they touch the steel and your joint is wet. Our recommendation here would be to assess scenarios where concerns about galvanic corrosion exist. A practical solution would be to isolate the metals with a nylon washer to lower the chances of them corroding.
