Corrosion resistant screws

Corrosion is what ends the service life of a fixing long before the load does. TGR protects its fasteners with four distinct systems, and the right one depends on the exposure: a warehouse roof inland, a coastal facade and a swimming pool enclosure are three different problems.

Below, the range is grouped by protection system rather than by product family, so you can specify by the environment the fixing has to survive. Certified classes are stated where the manufacturer declares them.
