Galvanised metal can be used for different purposes. For example, duct systems are often made of galvanised metal that is actually glued together. Additionally, you can use galvanised sheet metal for a number of different types of home improvement projects. If your project involves attaching any other type of materials to the galvanised metal, you will need to choose an appropriate method for the attachment. One method involves using a certain type of adhesive that is strong enough to bond the material to the galvanised metal.
Purchase the correct type of glue for gluing materials to galvanised metal. When attaching material to metal without other reinforcement, structural adhesive is the type of glue that will hold.
Load the structural adhesive into a construction-grade glue gun. It will come in cartridges that fit easily on the top of the gun. Refer to the manufacturer's instructions for additional details.
Check to be sure that the galvanised metal surface and the material you're bonding to it are completely dry.
Apply a bead of structural adhesive directly to the edge of the material that you plan to glue to the galvanised metal by applying consistent pressure to the trigger of the glue gun.
Pick up the material by its edges and place it firmly against the galvanised-metal surface. Continue pushing it in place for several seconds to ensure the adhesive bonds the two materials together.
