drill through galvanized pipe
Steel pipes can be galvanized for added protection. This process involves applying a layer of zinc to the surface of the pipe, creating a barrier that prevents rust and corrosion. Galvanizing the pipes also makes them easier to join through solder, thus making them great options for plumbing and electrical jobs.

A sharp drill bit is essential, and must be used with caution for an unhindered process. Drilling should only take place at a slow speed, to prevent breaking the bit. In addition, it is highly recommended to wear gloves and a face mask when drilling - the zinc fumes should not be taken in.
To join two pieces of pipe together, you will need to solder them. Begin by drilling a hole into one of the pieces. Use some sandpaper to rough up the area around the hole, and then apply flux to ensure the solder sticks. Using your soldering iron, heat the area until the pipe is just warm enough for you to add some lead-free solder. Touch the solder to the hole and let it melt onto the pipe's surface - applying a second layer if needed - before allowing it to cool.
