Metal Seals for Strapping/Banding
Heavy Duty Lapover Metal Seals for 13mm Steel Strapping (13mm x 25mm)
These heavy duty lapover metal seals are designed to secure steel strapping/banding where a strong, dependable joint is required. Sized to suit 13mm strapping and formed to a 25mm seal length, they are a practical choice for industrial strapping tasks such as bundling, unitising and stabilising loads for storage or transport. Used with the appropriate strapping tensioner and sealer, lapover seals help create a consistent closure that supports the performance of the strap in demanding environments.
Metal seals are a widely used method of joining steel strap because they provide a positive mechanical connection when crimped correctly. This product page may represent multiple pack quantities, so select the option that best suits your usage rate and site requirements.
Key Features

13mm x 25mm Heavy Duty Lapover Metal Seals — Full Product Guide
Choosing the right seal is essential for getting the best performance from a steel strapping system. The seal must match the strap width and be compatible with the sealing method used on site. The aim is to create a joint that holds securely under handling and transit stresses, while remaining efficient to apply in day-to-day packing.
How It Works
In a typical steel strapping setup, the strap is tensioned around the load and then joined using a metal seal. With a lapover seal, the strap ends overlap within the seal. A compatible sealer tool crimps the seal, deforming the metal around the strap layers to create a mechanical lock. When applied correctly, the seal helps maintain strap tension and supports the strap’s ability to keep the load stable.
Because tooling and strap specifications vary, always confirm that your tensioner/sealer combination is suitable for the seal style and strap you are using.
Materials and Construction
These are metal seals intended for steel strapping/banding applications. Metal seals are commonly selected for heavy duty strapping because they are designed to be crimped firmly and to resist movement once applied. The heavy duty format is intended to support demanding packing tasks where a strong closure is required.
Strap Width Compatibility
This product is specified as 13mm x 25mm:
- 13mm refers to the strap width the seal is designed to accept.
- 25mm refers to the seal length.
13mm steel strapping is widely used in industrial strapping systems and is commonly referenced as 1/2 inch in many catalogues and tooling ranges.
Tooling and System Compatibility
For best results, match the seal to:
- The strap width (13mm)
- The strap type (steel strapping/banding)
- The seal style (lapover/open style)
- Your sealer tool (must be designed for the seal style and strap width)
If you are unsure which sealer is appropriate, check your tool’s specification or contact us with your strap width and tool model so we can help confirm compatibility.
Floor Type Compatibility
These seals are used as part of a steel strapping process and are not floor-dependent. In practice, they are commonly used across warehouse, workshop and yard environments. As with any strapping operation, ensure you have a stable working area for tensioning and sealing, and keep the work zone clear of trip hazards from strap tails and offcuts.
Health and Safety
Steel strapping systems can store significant energy when tensioned. Follow safe strapping practices:
- Wear appropriate hand and eye protection when tensioning, sealing and cutting strap.
- Keep hands clear of the seal and tool jaws during crimping.
- Use the correct cutter and avoid uncontrolled strap recoil.
- Dispose of strap offcuts safely to prevent sharp-edge injuries.
Always follow your site’s safety procedures and the instructions supplied with your strapping tools.
Ideal Applications and Use Cases
Heavy duty lapover seals are typically chosen where steel strapping is used to secure heavier or more rigid loads. Common use cases include:
- Manufacturing: securing finished goods, components or assemblies for internal movement and shipment.
- Construction supply: bundling long products and building materials for delivery.
- Metal and timber trade: unitising bars, tubes, profiles, boards and packs.
- Export packing: stabilising loads where handling and transit conditions may be more demanding.
Maintenance, Cleaning and Care
Metal seals themselves require minimal maintenance, but good storage and handling helps maintain consistent application:
- Store seals in a dry area and keep them in their packaging until use.
- Keep your sealer tool clean and in good working order for consistent crimps.
- Periodically inspect sealed joints as part of your packing quality checks.
Case Study (Typical Example)
A warehouse team shipping mixed heavy goods uses 13mm steel strapping to stabilise pallet loads. By pairing a compatible tensioner and sealer with heavy duty lapover seals, they can create repeatable closures across multiple shifts. The result is a consistent strapping process that supports load stability during forklift handling and transport, while keeping packing time predictable.
Who is it for?
- Warehouses and despatch teams using 13mm steel strapping
- Manufacturers bundling or unitising heavier products
- Export packers and logistics operations needing robust strapping closures
- Sites that require a metal seal closure method rather than friction-weld or plastic buckles
Colours / Features Available
Metal seals are typically supplied in a standard metal finish. This listing focuses on the seal size and style (heavy duty lapover) rather than colour variants.
Sizes Available
This product listing is for 13mm x 25mm heavy duty lapover metal seals. Product pages like this may include multiple purchase options (for example, different pack quantities).
