From pattern shears to pelican shears - Which sheet metal shears for your project?
Working with sheet metal on roofs and façades requires maximum precision, because incorrect cuts cost materials, time, and patience. As a specialist online retailer, Roofify offers valuable insights into how roofers and sheet metal workers can choose the perfect tool for every construction requirement. Whether zinc, copper, aluminum, or stainless steel: a sheet metal project only becomes a craft success with the right tin snips.
Why the right roofing tool determines project success
Anyone working with roofing supplies and sheet metalworking supplies knows: not all tin snips are the same. Making an incorrect curved cut with aviation snips deforms the edge, while an unsuitable cutting angle can cause fraying when working with zinc and titanium-zinc sheets.
Choosing the right cutting tool depends on three factors:
- Material thickness & sheet type: Soft metals such as copper and aluminum require different blades from stainless steel.
- Cutting geometry: Long straight cuts require completely different designs from tight curves or notches.
- Leverage: Compound-action snips significantly reduce the effort required, providing relief during long workdays.
The main types of tin snips at a glance - Which tin snips are used for what?
1. The Ideal tin snips: The all-round genius
The Ideal tin snips belong in every professional tool set. They are truly versatile and combine the features of aviation snips with those of compound snips.
- Application: Long straight cuts and large-radius curves.
- Advantage: The cutting heads are designed so that the sheet metal passes beneath your hand without the sharp cut edge injuring the edges of your hand.
- Brand tip: Manufacturers such as Freund, MASC, and Stubai offer extremely durable Ideal sheet metal shears with induction-hardened blades.
2. The Pattern Shears: For Delicate Curves and Tight Radii
When radii and complicated contours are needed, ordinary sheet metal shears quickly reach their limits. That's where the pattern shears come in.
- Application: Tight curves, radii, and detail work on chimneys, dormers, and gutters.
- Advantage: The especially slim cutting head makes it easy to guide the shears precisely along fine marking lines.
- Special feature: Pattern shears come in separate versions for right- and left-hand cuts - professionals always keep both versions in their tool case.
3. The Pelican Shears: Specialists in Long, Straight Cuts
The pelican shears get their name from their distinctively shaped cutting head. They are designed for maximum efficiency when making continuous cuts.
- Application: Long, continuous straight cuts across large sheets of metal.
- Advantage: The cut sheet metal is fed under the workpiece. This prevents the material from warping and keeps your hands out of the danger zone.
- Pro tip: Ideal for installing large standing seam roofs.
4. The Round Hole Shears: Circular Cuts Without Edge Distortion
For cutouts in the middle of a sheet, such as for pipe penetrations or ventilation pipes, the round hole shears are the tool of choice.
- Application: Rounded cutouts and interior holes.
- Advantage: Curved blades prevent the edges from folding over during circular cuts.
- How to use: After pre-punching or drilling a starter hole, the shears can be guided smoothly in a circle.
5. The Notching Shears: Perfect for Corners and Edges
When bending sheet metal profiles, corners must be precisely notched so the folds fit together neatly.
- Application: Preparing standing seams, corner cutouts, and bends.
- Advantage: Sharp, well-defined V-shaped cutouts without burrs.
6. The sheet metal nibbler: Burr-free cutting without sparks
The sheet metal nibbler (also called a nibbler) works by punching.
- Applications: Profiled sheets, trapezoidal sheets, and corrugated sheets.
- Advantage: It does not distort the workpiece and leaves burr-free cut edges. Since no heat is generated, the corrosion protection (zinc coating) remains intact.
Comparing sheet metal snips
| Sheet metal snips | Primary application | Curved cut | Straight cut | Effort required |
| Aviation snip | Versatile use, curves & straight cuts | Good | Very good | Low (with leverage) |
| Curved snip | Fine contours, tight radii | Excellent | Moderate | Medium |
| Pelican snip | Long, continuous sheet metal panels | Not suitable | Perfect | Low |
| Circle snip | Pipe penetrations, round cutouts | Perfect (circles) | Not suitable | Medium |
| Notching snip | Corner cutouts for standing seam & bending | Not suitable | Specialty (V-cut) | Low |
| Sheet metal nibbler | Trapezoidal & corrugated sheets, no distortion | Good | Very good | Very low (electric/battery-powered) |
