RAL Rivet

The RAL blind rivet is named after the certified RAL colour palette. The product consists of a sleeve (shell) and a steel pin. The sleeve’s head is painted in one of the palette’s colours. The sleeve is usually made of a softer material than the pin, typically aluminium. The pin is made of zinc-plated steel. Combined rivets made of zinc-plated steel and stainless steel are also common.

Applications

RAL rivets serve a decorative function through the painted head and a utilitarian one — fastening two or more roofing or other structural elements together. The rivet can be used as a reliable fastener even without access to both sides of the joint: due to its expanded head, it fixes firmly in the material. The rivet is not suitable for sealed joints. Installation is performed with a special rivet tool.

Features

The rivet’s coloured coating, together with the zinc layer on the pin, protects against temperature and humidity fluctuations as well as direct sunlight. The rivet colour is selected from the RAL palette to match the specific roofing material.
