What is Perforated Metal Strapping

Perforated metal strapping is made from thin steel that has been perforated with punched holes at regular intervals. The holes are precisely punched by perforating machines and can vary in size, spacing, and arrangement based on the desired strapping properties and applications.

The holes enhance the flexibility and bendability of the straps while maintaining strength and limiting stretch. Perforated strapping comes in various widths, thicknesses, strengths, and finishes to accommodate many fastening needs. Galvanized or stainless steel is often used to resist corrosion.

Compared to other strapping methods, perforated metal strapping provides an optimal balance of strength, flexibility, durability, gripping ability, and breathability. The perforations make the straps lighter than solid steel while allowing for air circulation.

What is Perforated Metal Strapping Used For

Jiangmen Masters perforated metal strapping has become a staple across industries due to its versatility, adaptability, and performance. Some of the most common applications include:

Binding and Securing Heavy Loads

Perforated strapping is extensively used for binding and securing heavy loads during transit. It is commonly used for securing cargo on trucks, trailers, railcars, and ships. The strapping firmly fastens items together and onto the transport vehicle.

The combination of strength and flexibility provided by the perforations makes perforated metal strapping ideal for securely binding loads containing heavy, awkward, or irregularly shaped items. It allows the straps to flex and bend while limiting stretch.

Bundling Awkward Loads

Perforated steel strapping is also well-suited for bundling awkward, oddly shaped loads such as pipes, cylinders, drums, coils, rods, and beams. The punched holes allow the straps to contour and conform closely to the item.

For example, perforated strapping can encircle a bundle of pipes or rods, binding them together securely thanks to the improved grip and friction provided by the holes. This helps stabilize loads containing loose or unwieldy items.

Providing Flexible Connections

In industrial settings, Jiangmen masters perforated metal strapping is used to provide flexible connections between machinery components. The perforations add the needed flexibility to accommodate vibration, movement, and frequent adjustments without breaking.

Strapping with custom hole spacing can connect parts that require slight flexing, swinging, or frequent repositioning. This helps dissipate energy and prevent damage.

Clamping Construction and Outdoor Items

Contractors often use perforated steel strapping for temporary clamping and securing of items in construction, maintenance, and outdoor applications.

The holes allow nails, screws, bolts, or ties to pass through to fasten the straps. Workers can rapidly clamp and secure pipes, rebar, forms, ducting, and more. This temporary fastening improves workplace organization and safety.

Securing Wood

Perforated metal strapping is also used by the forestry industry for bundling and securing logs, lumber, and other wood products. The strapping can be tightly wrapped around a bundle of wood and secured in place using nails, staples, or fasteners through the holes.

This method firmly binds wood bundles and is easy to undo when needed. The grip provided by the holes prevents slippage.

Benefits of Perforated vs Solid Strapping

Perforated metal strapping provides several notable benefits compared to using solid steel strapping:

Increased Flexibility

The holes punched in perforated strapping greatly improve flexibility while limiting stretch. By removing some material, the straps can flex, bend, and contour more easily compared to solid straps.

This allows perforated metal strapping to adapt to awkward, uneven, or changing loads. Flexibility is also useful when binding vibrating machinery or connecting moving parts.

Lighter Weight

Due to the perforations, Jiangment masters perforated metal strapping has less overall material than an equivalent sized solid strap. This contributes to increased lightness and ease of handling.

Workers can carry and apply more strapping, speeding up the process of binding and securing loads. The lightness also reduces shipping costs.

Customizable Hole Properties

With perforated metal strapping, the size, spacing, and arrangement of holes can be customized to suit different needs. More holes provide increased flexibility while larger holes reduce weight.

Special hole shapes and directions can improve grip and strength in certain orientations. Companies can work with manufacturers to develop optimized perforated straps.

Enhanced Grip and Friction

The punched holes in Jiangment masters perforated metal strapping provide many contact points with the underlying surface. This multi-point grip improves holding friction.

The reduced area decreases the risk of slippage, sliding, or roll out. Loads stay firmly in place regardless of vibrations, shifts, or movements.

Air Circulation

The perforations allow ventilation and airflow across the bands. This circulation prevents interior moisture accumulation or corrosion when strapping outdoor items.

Strapped items can breathe while remaining securely bound. The holes also provide drainage points for any collected liquid.

Retained Binding Strength

Despite the holes, perforated strapping maintains most of the binding strength of solid straps. The remaining material between the perforations provides ample strength, while the holes enhance grip.

Custom spacing, hole size, and strap width can achieve the desired balance of flexibility and strength retention.

Comparing Weight to Other Strapping

The weight of perforated metal strapping depends on the thickness, width, steel grade, and hole properties chosen. However, in general, it weighs noticeably less than equivalent solid steel strapping.

Some approximate weight comparisons:

  • 1/2 inch perforated steel strapping is around 25% lighter than solid 1/2 inch steel strapping.
  • 3/4 inch perforated strapping can be 20% lighter compared to 3/4 inch solid strapping.
  • For 1 inch wide strapping, perforated types may be 15% lighter.

So for a given strap width, perforated strapping provides significant weight savings over solid alternatives while retaining most of the strength.

Compared to non-steel straps:

  • Plastic and poly straps weigh less than steel strapping. They can be around 50% lighter than perforated steel.
  • However, plastic/poly straps sacrifice a lot of strength, grip, and durability compared to steel.
  • Fiber straps like PET weigh 25-50% less than perforated steel strapping. But fiber also lacks the binding strength.

So perforated metal strapping provides an optimal balance – lighter than solid steel while stronger than plastic or fiber alternatives. The perforations enhance properties beyond what each material alone can provide.

Choosing the Best Perforated Strapping

Several factors should be considered when selecting the optimal perforated metal strapping for an application:

  • Load weight and binding demands – Heavier loads require wider, thicker straps with higher strength ratings. Customize hole spacing to retain strength.
  • Flexibility needs – Applications requiring more flexing call for increased hole size and density. But balance with strength.
  • Corrosion resistance – Galvanized or stainless steel strapping improves weather and chemical resistance.
  • Cyclic loading considerations – Frequent binding/unbinding cycles may require more durable, tempered steel.
  • Sharp edge items – Larger hole size prevents cutting or abrasion damage.
  • Maximum bundle size – Longer, higher capacity strapping allows larger, bulkier loads.
  • Environment – Indoor vs outdoor usage determines metal type, coatings, and corrosion allowances.

With many possible permutations, work closely with Jiangmen masters perforated metal strapping manufacturers to develop the optimal strapping solution. Let them know your binding needs and operating conditions. Sample testing can also help choose the right perforated strapping product.


Perforated metal strapping provides unmatched performance and versatility for binding, bundling, fastening, and clamping all types of loads and items across many industries. The custom punched holes enhance flexibility and grip while retaining strength.

Compared to alternatives, perforated metal strapping offers better durability, weather resistance, gripping friction, and adjustable properties. With the ability to customize hole size and spacing, perforated strapping can be tailored to achieve the perfect balance required by the application.

Next time you need strong and dependable steel strapping, consider punching some holes in it! Perforated metal strapping takes this traditional product to the next level.
