Best Way to Cut Corrugated Iron
Corrugated iron is a versatile and durable material often used for roofing, siding, and other construction projects. However, cutting it can be a challenging task due to its wavy surface and sharp edges. To ensure a clean and safe cut, it’s essential to use the appropriate tools and techniques.
The most efficient tool for cutting corrugated iron is an electric shear. These shears are designed with a powerful motor and heavy-duty blades that can easily cut through the material without causing any distortion or burring. For smaller projects, hand shears can also be used, but it will require more effort and may not provide as clean a cut.
When cutting corrugated iron with electric shears, it’s important to use a cutting oil or lubricant to reduce friction and prolong the life of the blades. The lubricant also helps prevent the material from overheating, which can cause it to warp or burn.
When cutting with hand shears, place the material on a flat, stable surface and secure it with clamps to prevent it from moving. Start by making a small pilot hole at the desired cutting line using a drill bit that is slightly smaller than the diameter of the shear blades. Then, insert the shear blades into the pilot hole and slowly cut along the line, applying even pressure throughout the cut.
