How to Glue Materials Onto Galvanized Metal


Galvanized metal is a combination of steel and zinc that has gone through a chemical process in order to help keep the steel from corroding. The process involves alloying the steel with another metal where it normally uses zinc material. Once the steel is submerged with melted zinc, the chemical reaction from the process will permanently bond the zinc onto the steel through galvanizing method. This process helps protect the metal from rust attack because the layers of zinc not only coat the steel, but it also permanently becomes a part of the metal. Galvanized metal can be used for various purposes that include for duct system, outdoor, marine, or industrial applications, plus also can be a vital component for fabrication. In addition, it can also be used for home improvement projects. As for projects that involve the galvanized metal to be attached to another type of materials, you need to use an appropriate approach in attaching the materials together. Through this piece, you will learn about the method used to glue other materials onto your galvanized metal.

To glue materials onto galvanized metal, you need:

  • Structural adhesive
  • Glue gun

Glue Materials onto Galvanized Metal

How To Glue Materials onto Galvanized Metal

  • The first thing that you need to do is to purchase a suitable type of glue that will help you glue the materials onto the galvanized metal.
    • The glue is available at your local hardware store or home improvement center.
    • One of the recommended glues that has the strength to hold both of the materials together is the structural adhesive. This type of adhesive is the most suitable glue to be used for the project due to its capability of attaching material onto metal without the need of other reinforcement.
  • Next step that you need to do is to load your structural adhesive right into a construction-grade glue gun
    • Always be careful with your hand or skin when you are using a construction-grade glue gun because when it is in operation, it will be quite hot.
    • The structural adhesive normally comes in cartridges that can easily fits on top of the glue gun.

Always ensure that you follow the manufacturer’s instruction provided on the label of the products for further details whenever you are using structural adhesive and also the usage of your construction-grade glue gun.

  • Before you start to glue anything, you must make sure to check that the galvanized metal surface and also the material that you want to attach to the metal are thoroughly dry. You can use a dry cloth to wipe the materials first before you start to glue the materials together.
  • After that, you need to apply a bead of the structural adhesive directly onto the edge of the material that you have chosen to glue onto the galvanized metal
    • Make sure that you always apply a consistent pressure on the trigger of the glue gun in order not to waste any of the structural adhesive.
  • Once you have finished applying the structural adhesive,
    • Then, you need to pick up the material right by its edges and securely set it against your galvanized metal surface.
    • You should continue pushing the material in place for several seconds in order to see the material holds onto the galvanized metal.
    • This is to ensure that the structural adhesive would be able to bond both of the materials together.

Always remember that galvanized metal normally use coated material made of all zinc.

  • However, the most successive layers in protecting metal against corrosion are the combination of mixture that includes zinc and iron.
  • The coated zinc used on galvanized metal acts as a protective layer against rust. If the surface of the galvanized metal were attacked by rust, the zinc will be the first layer that will get corroded first thus preventing rust from penetrating to the surface of the steel beneath the coats of zinc.
  • If you used multiple layers in galvanizing metal, it would be able to provide better protection and even having the ability to withstand any kind of corrosion-inducing conditions like saltwater as well as moisture.
