Strapping/Banding Tools/Trollies
13mm Steel Sealer — a dedicated hand tool used in steel strapping/banding operations to crimp and close a metal seal around tensioned steel strap. Designed for use with 13mm steel strapping systems, this sealer is a core part of a traditional three-piece steel strapping setup (strap + seal + tools), helping you create a secure, repeatable closure for bundling, palletising and load restraint tasks.
Because Sapphire product pages can cover multiple configurations, this guide focuses on what the tool does, how to choose compatible consumables, and best-practice use—without assuming a specific strap thickness, seal type, or load rating.
Key Features
Purpose-built for 13mm steel strapping
Engineered to crimp seals used with 13mm steel banding, helping you form a consistent closure when the strap has been tensioned.
Manual, workshop- and site-friendly operation
A hand-operated sealer is ideal where you need portability, quick setup, and dependable performance without power or air lines.
Supports repeatable seal closures
Using the correct seal and technique, a sealer helps produce uniform crimps across multiple packs—important for process consistency and operator confidence.
Integrates into standard steel strapping workflows
Pairs with a compatible steel strapping tensioner (or combination tool system) and the correct metal seals to complete the strapping cycle.
Simple tool maintenance
With routine inspection and cleaning, manual sealers are straightforward to keep in service—especially in dusty warehouse or yard environments.
- For 13mm steel strap systems (confirm strap width and seal style before ordering)
- Hand-operated for flexible use around the warehouse, workshop, or loading bay
- Designed to crimp metal seals after tensioning the strap
- Works as part of a tool set (typically used with a tensioner)
- Ideal for heavy-duty bundling where steel strapping is preferred
Typical Uses
- Securing pallet loads for storage or dispatch where steel strapping is specified
- Bundling timber, metal stock, pipes, profiles, or building materials
- Unitising heavy cartons, crates, or awkward loads that benefit from steel strap rigidity
- Strapping items for yard handling and transport preparation
- General industrial banding tasks in manufacturing and distribution
13mm Steel Sealer — Full Product Guide
A steel sealer is the closing tool in a steel strapping system. After the strap is wrapped around the load and tensioned, a metal seal is positioned over the overlapping strap ends. The sealer then crimps the seal so it grips the strap and holds the tension in place. Choosing the right sealer is mainly about compatibility: strap width, seal type, and the tensioning method you use.
How It Works
While exact mechanisms vary by tool design, the workflow is typically:
- Wrap the steel strap around the load and overlap the strap ends.
- Place a metal seal over the overlapped strap ends (seal style must match your system).
- Tension the strap using a compatible tensioner (or a combination tool if your system uses one).
- Crimp the seal using the 13mm steel sealer to lock the seal onto the strap.
- Finish by cutting the strap (often done by the tensioner or a separate cutter, depending on your setup).
The sealer’s job is not to tension the strap—it is to secure the seal closure so the tension you applied is retained.
Materials and Construction
Steel strapping tools are built for demanding environments. A manual sealer is typically manufactured from robust metal components to withstand repeated crimping cycles and the forces involved in closing steel seals. In day-to-day use, durability is influenced by:
- Correct matching of tool to seal and strap width
- Operator technique (square alignment and full stroke)
- Routine inspection for wear at crimping jaws and pivot points
Compatibility: Strap Width, Seal Type and System
Strap width: This tool is intended for 13mm steel strapping systems. Always confirm the strap width you use matches the tool specification.
Seal type: Steel strapping commonly uses metal seals that are crimped (for example, open seals). Sealers are designed to work with specific seal styles and crimp patterns. If you are replacing an existing tool, match the new sealer to the seal type you already stock.
Tool system: Many operations use a separate tensioner plus a sealer. Others use a combination tool that tensions and seals. This product is a sealer, so ensure you have (or plan to purchase) the appropriate tensioning method for your strap and application.
Floor Type Compatibility
This is a hand tool and is not floor-dependent, but your working environment affects usability and safety:
- Warehouse floors: Ideal for bench or pallet-side strapping where you can keep the tool square to the seal.
- Yard or outdoor areas: Keep the tool clean and dry where possible; grit can accelerate wear at moving joints.
- Vehicle loading bays: Ensure stable footing and adequate clearance to complete the crimp stroke safely.
Health and Safety
Steel strapping stores energy when tensioned and can cause injury if mishandled. Good practice includes:
- Wear PPE such as gloves and eye protection when tensioning, sealing, and cutting steel strap.
- Keep hands clear of the seal area during crimping; maintain a firm grip on the tool handles.
- Use the correct seal for your strap width and system—incorrect seals can slip or fail.
- Inspect strap edges; steel strap can be sharp, especially at cut ends.
- Do not exceed your system limits; ensure your strap, seals, and tools are appropriate for the load and handling method.
Ideal Applications and Use Cases
A 13mm steel sealer is commonly chosen where steel strapping is preferred for its rigidity and performance in tougher conditions. Typical scenarios include:
- Industrial bundling: securing long or heavy items that benefit from steel strap stiffness.
- Export and transit preparation: unitising loads where robust strapping is part of the packing specification.
- Manufacturing and fabrication: strapping finished goods, components, or raw materials for internal movement.
- Distribution: reinforcing pallet loads that may be handled multiple times.
Maintenance, Cleaning and Care
To keep your sealer working smoothly:
- Clean regularly: wipe down after use, especially if used outdoors or around metal dust.
- Inspect crimping surfaces: look for rounding, chipping, or uneven wear that could affect seal closure.
- Check pivots and fasteners: ensure joints move freely and hardware remains secure.
- Store properly: keep in a dry place to reduce corrosion risk.
- Test closures: periodically verify seal quality as part of your packing QA process.
Case Study (Typical Workflow Example)
Scenario: A warehouse team needs to secure mixed heavy items on pallets for dispatch. The loads are awkward and may be handled by forklift multiple times.
- The operator wraps 13mm steel strap around the palletised load.
- A compatible metal seal is placed over the overlapped strap ends.
- The strap is tensioned using a steel strapping tensioner to remove slack and stabilise the load.
- The 13mm steel sealer is applied squarely over the seal and fully actuated to crimp the seal.
- The strap is cut and the closure is visually checked for a consistent crimp.
Result: A repeatable, secure closure that supports handling and transport requirements where steel strapping is specified.
Who Is It For?
- Warehouses and distribution centres using steel strapping for heavy or rigid loads
- Manufacturing sites bundling metal stock, timber, or building materials
- Packaging teams that already use 13mm steel strap and need a compatible sealer
- Maintenance departments and yards that require a portable, manual sealing tool
Colours / Features Available
Tool appearance and finish can vary by batch and manufacturer. Focus on functional compatibility (strap width and seal style) when selecting.
Sizes Available
This listing covers a 13mm steel sealer. If you use other strap widths, Sapphire may offer alternative sealers and matching tools for different steel strapping systems. If you require guidance on selecting the correct tool for your strap width and seal type, contact Sapphire with your current strap and seal details.
