Galvanized Steel Strapping: Hot-Dip Zinc Coated & Waxed for Outdoor and Sea Freight Loads
JUHONG makes galvanized steel strapping in Changzhou, China, and has made steel strap since 1997. We slit it from hot-dip galvanized steel and then wax it, and every size and grade on our spec sheet can be supplied this way, from regular duty to high tensile. Choose it when the strapped load will stand outdoors or near the coast, or spend weeks at sea. Distributors, importers and manufacturers buy it by the container, together with the seals and tools that fit it.

What Is Galvanized Steel Strapping (Zinc Coated Steel Banding)?
Galvanized steel strapping is cold rolled steel strap with a zinc coating. We start from hot-dip galvanized steel coil, where a molten zinc bath has bonded a zinc layer to the steel, slit it to strap width, smooth the edges and add a coat of wax. Buyers also call it zinc coated steel strapping, galvanized steel strap or galvanized steel banding, and in the UK it is spelled galvanised. It is packaging strap for bundling and unitizing loads, a different product from the punched galvanized hanger strap sold for plumbing and building work.
How the Zinc Coating Protects the Strap
Zinc protects steel in two ways. The coating keeps moisture and air off the steel, and because zinc is more reactive than steel, it corrodes first. Where the strap gets a small scratch in a tool or seal, the zinc around it keeps protecting the exposed steel, so galvanized strap lasts far longer outdoors than painted or blue strap. Our hot-dip galvanized strap is slit from galvanized coil, so the zinc covers both faces and the slit edges are protected by the wax. The wax also lubricates the strap, so it slides and tensions smoothly in friction-type tensioners, and it gives the zinc a little extra protection in storage.
Product Finish Compared: Galvanized vs Black Painted vs Blue Tempered Steel Strapping
Our steel strapping products come in three finishes that cover most export and domestic orders. They differ in durability and cost, so choose by storage time, climate and shipping route.
Galvanized (hot-dip zinc coated) & waxed
Hot-Dip vs Cold Galvanized (Zinc Coated) Steel Strapping
Galvanized strap is made in two ways, and suppliers use the names loosely. Hot-dip galvanized strap is slit from steel coil that has run through a molten zinc bath, so the zinc is a metal layer bonded to the steel. It shows zinc spangle, the crystal pattern that forms as the zinc cools, and covers both faces, while the slit edges are protected by wax. This is ASTM D3953 Finish B and our standard galvanized steel strapping.
Cold galvanizing is a general name for zinc applied without a molten bath, such as electro-galvanizing or a zinc-rich coating. Our cold galvanized strap is slit first and then coated with zinc and waxed on our coating line, the same way we paint black strap, so all four sides are covered and the surface is smooth, with no spangle. Much of the strap sold as “zinc coated” in North America is this kind, a zinc-enriched coating that ASTM D3953 calls Finish C. When you compare prices between suppliers, ask which one you are being quoted. We make cold galvanized strap on request: contact us with your size and quantity.
| Hot-dip galvanized | Cold galvanized | |
|---|---|---|
| How it is made | Slit from hot-dip galvanized coil, then waxed | Slit first, then coated with zinc and waxed |
| Zinc on | Both faces | All four sides: both faces and both edges |
| Edges | Protected by wax | Zinc coated |
| Surface | Zinc spangle | Smooth gray, no spangle |

| Choose it for | Long outdoor storage, coastal yards and sea freight (our standard) | Zinc on the edges too, or matching a zinc coated strap you already buy (on request, contact us) |
When Galvanized Strap Is Worth the Higher Cost
Galvanized strap has the highest price of our three finishes, so use it where the extra corrosion resistance pays for itself:
- Loads stored outdoors for months, such as lumber, bricks, pavers and steel pipe in open yards.
- Coastal ports and humid climates, where salt air attacks painted strap.
- Long sea voyages and open-top railcars or flatbed trucks, where the strap is exposed in transit.
- Products where you need to prevent rust stains from the strap, such as galvanized pipe, galvanized coils, lumber and finished building materials.
For loads that stay in a container and then go indoors, black painted steel strapping is usually enough and costs less.
Galvanized or Stainless Steel Strapping?
Stainless steel strapping resists corrosion better still, but it costs much more and is used where chemicals, constant salt spray or hygiene requirements make zinc unsuitable. For bundling and palletizing heavy loads that are stored outdoors, galvanized steel strapping gives most buyers the protection they need at a far lower price.
Galvanized Steel Strapping Sizes: Width, Thickness, Tensile Grade & Break Strength
Every size and grade below can be hot-dip galvanized and waxed, from 1/2 in to 2 in wide and 0.015 in to 0.047 in thick, including common sizes such as 3/4 in x 0.031 in and 1-1/4 in x 0.035 in or 0.044 in zinc coated steel banding. Break strength depends on width, thickness and tensile class.

Average break strength of one strap. Width tolerance ±0.10 mm. Length / Weight shows how much strap you get per pound or kilogram, so you can work out the footage per coil from the coil weight. Coil winding: M = mini, R = ribbon wound, O = oscillated wound, J = jumbo. A dash means the size is not made in that grade.
ASTM D3953 Finish B and Zinc Coating Grades
Under ASTM D3953, galvanized strap is Finish B, and the zinc coating comes in three grades: Grade 1 (heavy coating), Grade 2 (moderate coating) and Grade 3 (commercial coating). Grades 1 and 2 are often called government-grade galvanized. If your specification names a coating grade, for example “1-1/4 x 0.035 Grade 1 zinc coated steel banding”, send it with your inquiry and we will confirm whether we can meet it before we quote.
Tensile Strength Grades in Galvanized: Regular Duty to High Tensile
Every grade can be supplied galvanized: Terra 650, Ridge 750 and Pivot 830 N/mm² for regular duty steel strapping, Duro 930 and Nexa 980 N/mm² for high tensile steel strapping, and our UltiMax high tensile, high elongation strap at 900 or 1,000 N/mm². All our strap is made from low-carbon steel.
Coil Formats: Ribbon, Oscillated, Jumbo & Mini
Galvanized steel strapping comes in the same four coil formats as the rest of our range. Match the format to your tool and dispenser.
Ribbon Wound (RW) Coils
25 to 50 kg per coil, inside diameters of 200, 300 or 406 mm, for manual tools and semi-automatic tools. About 1,000 kg per pallet.
Oscillated Wound (OW) Coils
40 to 50 kg on a 406 mm inside diameter, for pneumatic tools, long shifts and automatic strapping. Needs an oscillated-coil dispenser. 12 to 18 coils per pallet.
Jumbo Coils
170 to 1,000 kg on 406 or 610 mm inside diameters, for automatic strapping lines. Most jumbo coils are 32 mm wide. Heavy coils reduce coil changes and make packing faster.
Mini Coils
Under 25 kg and easy to handle, for small orders, field work and trials.
Manufacturing: How We Slit and Wax Hot-Dip Galvanized Strapping
On our line in Changzhou, hot-dip galvanized steel coil is slit to strap width and the edges are smoothed to remove burrs. The strap is then waxed, dried, air-cooled and rewound, and packed for shipping.

Tensile and Elongation Tests
Break strength and elongation set one grade apart from the next. SGS has tested our steel strapping to GB/T 25820 and EN 13246, and the reports are on our Downloads page. For orders bound for North America, we can test to ASTM D3953 on request.
In-Line Checks Every Two Hours
Every two hours, inspectors take 10 coils from the line and check width, thickness, tensile strength and bend performance. A failed bend or tensile result stops the line.
Galvanized Steel Strapping Applications by Industry: Lumber, Steel Pipe & Wire Coils
Buyers across the steel, metals and building materials industries use galvanized steel strapping wherever a strapped bundle will be exposed to weather. Steel mills and pipe makers use it on galvanized coils, structural steel, rebar, square tubes and ductile iron pipe stored in open yards or shipped through humid ports, and on galvanized products, where rust stains from the strap would mark the product. Non-ferrous metal plants use it on copper cathodes, metal ingots and wire rod coils.
Lumber yards, brick and paver plants and building supply yards use it on loads that wait outdoors before sale, and it is also used on open-top railcars, flatbed trucks and export cargo that crosses the sea. For more strapping applications, see our steel strapping page.
How We Pack Galvanized Steel Strapping Coils for Export
Galvanized strap still needs careful packing for shipping. Zinc that stays wet with no air flow, such as coils sweating inside a container, can form white rust, a white powder on the surface. Every coil is wrapped in anti-rust paper as standard, and every sea-freight order gets VCI anti-rust film. Each pallet also gets a rust-preventive desiccant and an outer layer of moisture-resistant wax paper, held with four straps on a sturdy fumigation-free wooden pallet or a steel pallet. Tell us how you want your coils labeled, and we will confirm what we can supply under your brand. Ask for a container loading plan with your quotation.
Coils on the Pallet
Coils are stacked on a fumigation-free wooden pallet or a steel pallet.
Individual Packing
Each coil is wrapped on its own in anti-rust paper.
Desiccant
A metal rust-preventive desiccant goes inside each pallet.
VCI Plastic Film
The coils are enveloped in VCI anti-rust film, standard for sea freight.
Humidity-Proof Wax Paper
Moisture-resistant wax paper covers the outside, with four straps for reinforcement.
Delivery
Packed pallets are loaded into the container by forklift.

Strapping Seals and Tools for Galvanized Steel Strap
Seal width matches the width of the strapping band, and the seal style follows your tool: push type, snap-on, thread-on or open seals for manual sealers, and magazine seals for machines. We make seals in two finishes, galvanized and plain cold-rolled. For loads that stand outdoors, use galvanized seals with galvanized strap, so the joint does not rust before the strap does. We can ship strapping seals in the same container as the strap. Send us your tool model and we will confirm the strap and seals that fit, and we can also supply manual and pneumatic tensioners and sealers to match.
Cutting tensioned strap is the main risk to safe handling. The strap can spring back when cut and its edges are sharp. To cut it safely, use a proper strap cutter, stand to one side, and wear protective gloves and safety glasses when you handle steel strap.
Switching Suppliers? Match the Galvanized Strap You Use Now
Whether you resell strap or run it on your own packing line, send a photo of your current coil label or spec sheet. We will match width, thickness, grade, finish and coil format, and send samples to test in your own tools and equipment. Distributors and importers can combine galvanized strap with the rest of our full line of strapping products, including seals, PET strapping and stretch film, in one container. Minimum quantities and lead time depend on size, grade and volume, so we confirm them with your quote.
Galvanized Steel Strapping FAQ
Short answers to the questions buyers ask us about galvanized strap.
Is zinc coated steel strapping the same as galvanized steel strapping?
Often, but not always. Galvanized strap has a metal zinc layer applied by hot dipping or electro-galvanizing. Some strap sold as “zinc coated” has a zinc-rich coating instead. We make both: hot-dip galvanized and waxed strap as standard, and cold galvanized (zinc coated) strap on request.
Is your galvanized steel strapping hot-dip or cold galvanized?
Hot-dip as standard. We slit it from hot-dip galvanized steel coil, so the zinc is a metal layer bonded to the steel, and then we wax it. Cold galvanized strap, coated with zinc and waxed after slitting, is made on request: contact us if you need it.
How can I tell hot-dip galvanized strap from cold galvanized strap?
Look at the surface and the edges. Hot-dip galvanized strap shows zinc spangle, the crystal pattern that forms as molten zinc cools, and its slit edges are waxed rather than zinc coated. Cold galvanized strap has a smooth gray finish with no spangle, and the zinc covers the edges too.
Does galvanized steel strapping rust?
It resists rust far longer than painted or blue strap, even outdoors and near the coast, because the zinc corrodes first and protects the steel. Kept wet with no air flow, zinc can form white rust, so store coils dry before use.
Does your galvanized strap meet ASTM D3953 Finish B Grade 1?
Galvanized strap falls under ASTM D3953 Finish B. Send us your size and the coating grade your spec calls for, and we will confirm whether we can meet it before we quote. We can also test to ASTM D3953 on request.
Galvanized or black painted steel strapping: which should I choose?
Choose black painted strap for container shipments that go into a warehouse on arrival. Choose galvanized strap when the load will stand outdoors, in a coastal yard or on an open vehicle for weeks or months. Both come in the same sizes and grades.
Why is galvanized strap also waxed?
The wax lubricates the strap so it slides and tensions smoothly in friction-type tensioners, and it adds a little protection to the zinc in storage.
Do you make 3/4″ and 1-1/4″ x 0.044″ zinc coated steel banding?
Yes. Every size from 1/2 in to 2 in wide comes galvanized, including 3/4 in x 0.031 in and 1-1/4 in x 0.035 in or 0.044 in, from regular duty to high tensile and UltiMax.
Which seals should I use with galvanized strap?
Galvanized seals of the same width. For outdoor loads they maintain the same rust resistance at the joint as on the strap. Tell us your tool and we will match the seal style.
How should I store galvanized steel strapping?
In a dry, ventilated warehouse, in the original wrapping and off the floor. To avoid white rust, do not leave wet coils packed tightly together.
