Metal strapping with holes, also known as perforated steel strapping or wavy strapping, refers to thin metal tape or banding that contains a series of punched holes or perforations along its length. This versatile product has become a staple across various industries due to its strength, durability, and flexibility in binding, bundling, and securing all kinds of items.

From construction sites to farms, metal strapping with holes provides an easy and effective way to stabilize loads, affix structures, organize wires and cables, and much more. But where exactly is wavy strapping used and how is it produced? This article will explore the varied applications and manufacturing process behind this indispensable product.

Applications of Perforated Metal Strapping

Perforated steel strapping truly shines in its broad usefulness across many settings. Here are some of the top uses of metal strapping with holes:

Construction and Building

In the construction industry, wavy strapping securely binds lumber, pipes, beams, ventilation ducts, rebars, and other structural components on building sites. Strapping is also used to attach roofing materials like tiles, shingles, and sheets to the underlying frames. The combination of strength and flexibility makes metal strapping ideal for providing additional structural support exactly where needed during construction.

Plumbing, HVAC and Mechanical Services

In plumbing, HVAC and mechanical services, perforated strapping neatly organizes and fastens together piping runs, ductwork joints, cable trays and ventilation layouts. The ability to tighten and seal strapping at variable points allows for secure fastening regardless of twists and turns in the system. This application takes advantage of both the stability and adjustability offered by the strapping.

Electrical and Cable Management

For organizing electrical systems and communication cables, whether in construction or industrial settings, metal strapping with holes provides a tidy and reliable wiring solution. Cables and wires can be spaced and grouped however necessary and then firmly affixed along their lengths. This offers protection, prevents sagging, and enables accessible yet secure cable runs.

Agriculture and Farming

On farms and agricultural settings, perforated strapping has become a jack-of-all-trades tool. It is extremely useful for staking and training crops, securely attaching irrigation lines, stabilizing fencing, and protecting plants with netting or other covers. The strapping holds up well against sun, moisture, soil and other elements common in outdoor farming environments.

Material Handling and Transportation

In warehouses, shipping centers, storage facilities and beyond, strapping is essential for stabilizing pallets of goods, bundling awkward loads, and securing crates or containers. Perforated steel strapping can firmly contain even heavy and irregularly shaped loads thanks to customizable fastening and immense tensile strength. This makes it ideal for handling all kinds of cargo and materials during storage and transport.

General Industrial Use

Finally, perforated strapping sees ubiquitous use across general manufacturing, maintenance, and repair jobs. It provides a quick and adaptable way to manage hoses, tools, parts, temporary structures, and any other components that need organization or securing in industrial settings. The diversity of applications within metalworking, auto repair, manufacturing, and similar fields is nearly endless.

Manufacturing Process of Perforated Metal Strapping

To create perforated strapping that can handle such varied demands, a specialized manufacturing process is used:

Raw Material Selection

It all starts with choosing an appropriate metal material for the demands of the job. Strapping is commonly produced from steel, aluminum, copper, or alloys and composites. Steel provides immense tensile strength. Aluminum offers increased corrosion resistance and lighter weight. Copper and brass provide aesthetic qualities in addition to strength. Material thickness and hole size/pattern are also determined based on intended usage.

Metal Shaping

Next the raw metal must be shaped into long, thin, flat strips that will form the strapping bands. This is done by machine rollers that gradually flatten and elongate the metal into the proper thickness and width. The metal is annealed and treated to impart additional strength and flexibility without becoming too brittle.


Once shaped, the most iconic stage begins: punching the pattern of holes into the strips. This is done by an industrial punch press which punctures the programmed hole shapes in a sequential manner as the strip moves through. The holes allow for secure fastening and adjustable tensioning along the full length of the strapping.

Coiling and Packaging

After perforating, the long strips are machine-coiled for compact storage and transport. The coils are packaged in quantities suitable for shipping and sale. At this stage the raw product is complete and ready for distribution to end users in construction, agriculture, factories, warehouses and more.

Fastening and Tensioning

The final steps come when a user uncoils the perforated strapping and applies it for an intended use. They determine the necessary length and use metal shears to cut. The strapping is wrapped and inserted through itself at the desired points to bind objects. Lastly, specialized tools like sealers and tensioners are used to firmly crimp the strapping and create durable tension at fixed points. This completes the journey from raw steel to versatile fastening solution.


Metal strapping with holes has proven its immense versatility through ubiquitous use in construction, utilities, farming, manufacturing, shipping, and countless other sectors. Its unique qualities offer the strength of steel combined with adjustable fastening ability thanks to the punched perforations. With knowledge of how wavy strapping is made, it’s easy to see why it can adapt to so many applications across industries where binding, bundling, securing and stability are required. Perforated metal strapping will continue to be a staple product for meeting fastening needs both common and unique.
