JUHONG manufactures push type seals in multiple widths, lengths, and surface finishes. Our push type seals are available in cold-rolled and zinc-coated options, with custom sizes, OEM packaging, and factory-direct supply for industrial steel strapping applications.
What Is a Push Type Seal for Steel Strapping?
Push type seals are steel seals designed for manual steel strapping applications where a strong and stable joint is needed on round, irregular, or difficult package shapes. Their sealing method makes them especially suitable for loads where the strap must form a loop around the product before tensioning.
Also Known as Closed Seal or Overlap Seal
Closed seal and overlap seal are commonly used alternative names for push type seals. These names refer to the seal structure and sealing method rather than a different product category. In practical use, they are all used for manual steel strapping applications where the strap ends are pre-threaded through the seal before tensioning.
Designed for Manual Steel Strapping Applications
Push type seals are mainly used with manual steel strapping tools rather than automatic seal-feed systems. They are suitable for operations where packaging speed is lower but strong joint holding and adaptability to difficult load shapes are important.
Why Push Type Seals Are Used for Round and Irregular Loads
Push type seals are widely used on packages that are not easy to secure with standard flat sealing methods. Their structure makes them especially suitable for round, coiled, or irregular shaped products.
Suitable for Coils, Pipes, and Rod Bundles
Push type seals are commonly used for steel coils, coiled wire, rods, pipes, and other round bundles where the strap must be formed into a loop around the product. In these situations, the seal must remain stable while the strap is tensioned around the load.
A Secure Choice for Irregular Package Shapes
For irregular shaped packages, push type seals help provide a more practical sealing solution than some other seal types. They are often selected when package geometry makes standard sealing methods less convenient.
Pre-Threaded Sealing for Stable Joint Positioning
Because the strap ends are threaded through the seal before tensioning, the seal stays in place during tightening. This helps make push type seals suitable for loads where controlled seal positioning is important.
How Push Type Seals Work with Manual Steel Strapping Tools
Push type seals are used in a different way from some other steel seal types. Their application method is one of the main reasons buyers search specifically for this product
Used with Push-Type Tensioners
Push type seals are typically used with push-type tensioners in manual steel strapping applications. The seal is positioned first, and tension is then applied while the tool works against the seal structure.
Why Pre-Threading Matters
Unlike open-flange seals, push type seals require the strap ends to be manually pre-threaded through the seal before tensioning. This pre-threading method helps keep the seal aligned and is especially useful on round or irregular products.
How the Strap Forms a Slip Loop Around the Load
In many applications, the steel strap is used directly from the coil and formed into a slip loop or lasso around the package. The strap ends are threaded through the push type seal, then pulled and tensioned to secure the load.
Push Type Seal Specifications and Available Sizes
The correct push type seal specification depends on strap width, load shape, and the manual tensioning method used. Our standard push type seal sizes cover 13 mm, 16 mm, 19 mm, 25 mm, and 32 mm steel strapping, with seal lengths from 22 mm to 75 mm for different application needs.

Available Widths and Lengths
Our standard push type seal range includes common steel strapping widths such as 13 mm, 16 mm, 19 mm, 25 mm, and 32 mm. Different seal lengths are available to match different strap sizes and application requirements.
How to Choose the Right Push Type Seal Size
A push type seal should be selected not only by strap width, but also by the shape of the load, the sealing method, and the tensioning tool used. Proper matching helps improve sealing performance and joint reliability.
Custom Push Type Seal Sizes Available
If your application requires non-standard dimensions, special packaging, or a specific finish, JUHONG can support custom push type seal solutions for industrial customers and distributors.
Cold-Rolled and Zinc-Coated Push Type Seals
![Closed seals with custom logo for steel strapping applications]( "Custom Logo Closed Seals for Steel Strapping")
JUHONG supplies push type seals in different finishes to meet different storage and packaging environments.
Cold-Rolled Push Type Seals for Standard Industrial Use
Cold-rolled push type seals are suitable for many general regular duty steel strapping applications where stable mechanical performance and cost efficiency are important.
Zinc-Coated Push Type Seals for Corrosion Resistance
Zinc-coated push type seals provide improved corrosion resistance and are suitable for export packaging, warehouse storage, or working environments where surface protection is important. In these conditions, they may be matched with black painted and waxed steel strapping or other corrosion-resistant steel strapping products depending on the packaging system.
Applications of Push Type Seals in Steel Packaging
Push type seals are suitable for manual steel strapping applications where round, irregular, or heavy bundles require a reliable seal structure.
Steel Coil and Coiled Product Packaging
Push type seals are often used on coiled products where the strap forms a loop around the load and the seal must remain stable during tensioning. In heavier-duty applications, they may be paired with high tensile steel strapping for stronger holding performance.
Pipe, Rod, and Round Bundle Strapping
For pipes, rods, and other round bundles, push type seals help provide a practical sealing method in manual steel strapping work.
Heavy-Duty Steel Strapping for Irregular Loads
In demanding packaging conditions, push type seals may also be used with blue and waxed steel strapping depending on load requirements, working environment, and corrosion resistance needs.
