Roofing seaming pliers AWTools D331-60 — single-piece metal sheet joining tool

AWTools D331-60 roofing seaming pliers are a single-piece hand tool designed for joining and forming metal roofing sheets. The tool provides mechanical crimping and alignment of sheet edges during roof installation and repair work. Built to be used manually, it enables accurate edge shaping and seam folding for a variety of roofing profiles and thin metal sheets.

Advantages

The one-piece construction delivers stable force transmission and reduces the number of moving parts, simplifying maintenance and improving durability. Its specific jaw geometry is made to seat and fold sheet edges consistently, helping to produce tight seams and flush joints. The tool is supplied ready for immediate use and requires no additional assembly or power source, making it convenient for on-site roofing and repair tasks.

Suitable for

• Manual joining and crimping of metal roofing sheets
• Edge shaping and seam forming during roof installation
• On-site repairs of gutters, flashings and sheet overlaps
• Work by roofers, metalworkers and maintenance technicians

Key specifications

• Tool type: single-piece roofing seaming pliers for metal sheets
• Primary function: mechanical crimping and alignment of sheet edges
• Suitable materials: thin metal roofing sheets and flashings
• Operation: manual hand tool, no power required
• Use environment: outdoor roofing work and repair sites

How to use

Position the tool jaws over the sheet edge or seam that requires folding or crimping. Apply steady hand pressure to close the jaws and form the desired seam, moving along the joint in short, controlled strokes for even results. Repeat the procedure along the length of the seam until the sheets are joined securely. For repairs, work from the outer edge toward the overlap to ensure proper seating and water-shedding geometry. Inspect formed seams visually to confirm consistent folds and adjust your stroke length and pressure if necessary.

Usage recommendations

Use appropriate personal protective equipment such as gloves and eye protection when handling metal sheets and operating the pliers. Select the correct sheet thickness and seam profile for manual seaming; where material is significantly thicker than standard roofing sheets, consider mechanical or powered seaming equipment. Store the tool in a dry place to avoid corrosion and check the jaws regularly for wear that could affect seam quality.
