While plasma cutters and oxy-acetylene torches are commonly used to cut metal sheets, if you don't have access to those tools and still need to cut some steel, there are alternative methods you can try.
Abrasive cutoff wheels can be used with an angle grinder to cut metal, but they aren't ideal for cutting flat sheets of metal. A circular saw that fits a 7" cutoff wheel can be an alternative, but be prepared for a shorter lifespan as the saw won't last long due to metal debris.
While not recommended, the individual in the video above claims to use a 10" cutoff wheel with his table saw for more precise cuts. He advises using a less expensive saw for this method, as sparks will fly everywhere due to the blade's high speed. This can be a fire hazard, so it's best to avoid this technique.
Finally, a reciprocating saw with a short cutoff blade can be set vertically over the metal sheet and used like a jigsaw. A jigsaw's blade is too flimsy for cutting sheet metal, making the reciprocating saw a better choice.
Always make sure to wear safety goggles and gloves when using a cutoff wheel.
