Corrugated metal roofing may be cut in a variety of ways. A circular saw on thicker pieces of metal can make long, straight cuts. If you don't want to use a power tool and need to make curved cuts, utilize a pair of snips. With a metal cutting tool, you'll be able to make longer cuts and use any sort of sheet metal more freely. However, since you must do it, wear gloves and a welding mask to minimize the danger of injury. Also, work in an area with good ventilation since corrugated metal emissions are harmful.
Method 1: Wood Cutting with a Circular Saw (How to Cut Corrugated Metal Roofing)
1- Wearing thick gloves and a welding helmet is a must.
Wearing gloves and a welding mask at the maximum level of protection is advised, as the blade guard will protect you from most sparks. Metal cutters can produce poisonous gases if they are used in an enclosed area.
2- Place the corrugated metal on top of the work surface.
Depending on your choice, you may use a sewing table or sawhorses. Place your corrugated metal on top of your work surface so that there is nothing in the way of your saw blade and the line directly below it.
3- Replace your saw blade with one that is made of metal.
If your knife's blade won't come out, release it and replace the blade. To remove your old blade, loosen the bolt in the center of your knife with a wrench and twist it off. Remove the flange and remove your old blade by prying it out with a flat-blade screwdriver. Slide in your new blade before firmly tightening
- It's important to know whether your circular saw is designed to cut metal since the majority of our products are made of it. If you're buying a circular saw for use in a workshop, make sure it has this marking on the side.
- While a diamond blade will give the best results, they are also more expensive than regular circular saw blades.
4- With your non-dominant hand, brace the corrugated metal and begin to cut.
Place the base plate of your saw against an edge where you want to start cutting. With your non-dominant hand, brace the metal and apply pressure while maintaining at least 2 feet (0.61 meters) between it and the saw. Pulling on the trigger of your saw carefully makes a first incision in the metal.
If you're struggling to pass the saw, consider hanging something hefty from the sheet metal. Clamps won't help much because corrugated metal's ridges make maintaining tension challenges.
5- Using a saw guide, cut the metal slowly.
Because your circular saw will be moving ahead with the saw blade, it will perform most of the work. Allow the excess piece you cut to drop freely to the floor as you move the saw slowly through the metal.
- When cutting at an angle, you run the danger of damaging your circular saw. Corrugated metal has grooves that make it easy to cut a straight line, but rotating your saw might cause you to lose control of it. A circular saw is the best method for cutting long lengths of straight lines in corrugated metal because it has a wider blade
Warning: If you get a kickback from your circular saw, release the trigger and allow it to stop before resuming cutting.
Method 2: Using the Snips (how to cut corrugated metal roofing)
1- Find a pair of metal-cutting snips that are appropriate for you.
Snips for metal and other materials are known as aviation snips or tin snips. They're used to cut metal in a variety of ways. They're usually labeled depending on what you want to accomplish with them. Green snips cut to the left, red snips cut to the right, and yellow snips cut in a straight line.
Tip: Green snips are best for performing clockwise cuts, while red snips are ideal for counter-clockwise cuts. Green snips can be employed to make clockwise cuts and red snips to make counter-clockwise cuts.
2- Take off your jewelry and put your metal on a flat, firm surface.
When you cut with snips, you'll be working with the corrugated metal's edge, so you'll need a thick pair of construction gloves to ensure that you don't get harmed. After you've put your gloves on, place your metal on a flat and stable surface.
3- Lay your snips along the metal sheet's edge and grip the side.
With your non-dominant hand, grasp the metal on the opposite side. You'll be able to pull it up while you cut, and this will keep it in position. Place the two blades around the edge of the board that you'd want to cut. Hold the snips in your hand and wrap them around the line.
4- Using a fine-toothed blade, carefully cut around the individual pieces to remove any burrs or sharp edges.
- To cut through corrugated metal, squeeze the snips' handles together. After cleaning the shower or bathtub, replace and tighten the handles. Remove the levers first before pushing them ahead a bit; then repeat. Make a mental note of where your dominant hand is on the metal surface. Using your dominant hand, begin cutting at that point and lift the extra section of metal upward with your nondominant hand to allow room for your dominant hand to continue cutting. If you master this, you'll be able to cut the cords with a pair of scissors! You'll think you're using a pair of scissors if you do it correctly!
- If you leave your dominant hand on top of the region you're cutting and your non-dominant hand underneath it, you'll risk losing control of the snips or injuring yourself on the edge.
- This technique works well for cutting small strips of metal or making angled cuts.
Using a saw or snips to cut your metal may seem intimidating, but it is quite easy. When using the method of cutting with a saw, you need to make sure that there are at least 2 feet (0.61 m) between it and your saw. The first incision should be made carefully by pulling the trigger on the circular saw while making sure not to let any part of your body get close enough for injury from kickback. If you're not confident with passing the saw, consider hanging something heavy in front of the sheet metal so you can guide yourself through without doing too much work. You'll want thick gloves when using this method because if anything goes wrong while cutting with a blade, cuts will happen quickly!
