High Tensile 25mm PET Strapping Band 11760N For Brick Aluminum Ingot Bundling

I am the engineer responsible for our 2512 high-tensile line, and this is the band I developed for two of the hardest jobs in heavy industry: brick bundles and aluminum ingot stacks. The 2512 is built 25 mm wide and 1.2 mm thick, which lifts the breaking strength to 11760 N, the highest figure we produce. That extra figure matters on metal: a dense aluminum ingot has sharp, unforgiving edges, and a thinner strap will cut or creep long before it ever reaches its rated load. I run every coil from 100% virgin PET polyester on our own imported production lines, and I verify the tensile, weld and dimensional results on each batch before it is released.

This is a 2512 coil from my line. The 25 mm ultra-wide, 1.2 mm heavy-gauge body is exactly what lets it survive the sharp edges of brick and aluminum ingot bundles without cutting through.

• 11760 N Breaking Strength: the highest rating we build, matched to dense metal and mill products where steel belt was previously the only option.
• 25 mm × 1.2 mm Heavy-Gauge Body: a wide face and an upgraded gauge together resist edge cut-through far better than a standard strap.
• Superior Edge Cut-Through Resistance: I spec this grade specifically for the sharp, abrasive edges of ingots, billet and stone.
• Excellent Tension Retention: the strap re-tensions as a load settles or compresses, so it stays tight through long transit cycles.
• Non-Sparking and Burr-Free: safe in mill and foundry environments, with no sharp edges to injure your crew.
• Rust-Free: no corrosion or staining of goods, which is the reason so many steel users switch to PET.
• Recyclable: a clean, eco-friendly replacement for steel belt.

For dense metal and mill products, steel belt is the traditional answer, but it brings rust, sharp edges and heavy handling. The 2512 was built to match the holding jobs steel was used for, with 11760 N of break strength across a 25 mm face, and to do it without the corrosion that ruins finished goods. In my experience the switch usually pays for itself twice: once on the packing line, where operators handle a light, non-sparking, burr-free band instead of sharp steel, and once at the customer, where no one has to reject a shipment for rust marks. If your load is dense and its edges are unforgiving, this is the grade I would put in your hands.

Every 2512 coil is extruded from virgin PET polyester on our imported lines and drawn to align its molecular structure. Running one recipe at volume is what keeps the 11760 N tensile strength identical batch after batch.

On the heaviest loads, buyers often assume steel is the only safe option. Here is the comparison I give them:

What I tell every buyer is simple: with the 2512 you keep steel-class holding power and lose the rust, the sharp edges and the metal weight that comes with it.

I built the 2512 for dense, edge-hazard loads: bricks, aluminum ingots, glass products, lumber, stone material and heavy pallet cargo packing. It is what I recommend as a direct replacement for steel belt where rust, sharp edges and metal weight are constant problems, and it performs reliably across long-distance ocean freight, rail and road transport.

This is the 2512 doing the job I designed it for: holding a dense brick or aluminum ingot bundle tight and square, with the wide, thick body keeping the bundle intact even when the load shifts.

Every batch passes the checks I insist on before it can ship, because at 11760 N I do not sign off on assumptions:

• Tensile testing: I pull a sample from each batch to confirm the rated 11760 N breaking strength and the 11%–14% elongation range.
• Dimension inspection: width and thickness are measured to hold the 25 mm and 1.2 mm specification, together with core diameter and coil length.
• Surface inspection: every coil is inspected for a clean, uniform finish and burr-free edges before packing.
• Weld strength check: heat-sealed joints are tested to confirm a weld efficiency of ≥85% of breaking strength.

Everything above is backed by a real, auditable company. We are Xiangyang Suhai Machinery Equipment Co., Ltd., founded in February 2011 in Hubei, China, with a registered capital of RMB 19 million and an annual output capacity of 36,000 tons of PET strapping. We are recognised as a National High-Tech Enterprise (Certificate No. GR202442006492, issued 26 December 2024, valid for three years) and were selected for Hubei Province's 7th batch of Specialised, Refined, Differentiated and Innovative SMEs — official confirmation of our R&D capability rather than a self-declared claim. Our manufacturing is certified under quality, environmental and occupational health & safety management systems, and our products are supported by SGS test reports. Full certificate copies and test reports are available on request for your compliance file.

Each roll is wrapped in a plastic protective film and stacked on standard wooden pallets for container or full-truck shipment. Production starts after we receive your deposit, and goods are delivered upon full balance payment, with a lead time of 5–10 working days. We welcome third-party inspection and factory audits on any order.

Finished coils are consolidated onto export pallets and unitised for stable container loading — the clearest proof of the band's holding power under real shipping conditions.

Each coil is wound on a rigid 250 mm core and precision-cut to a consistent 25 mm width, so the strap feeds cleanly through both manual tools and automatic strapping machines.

• Q: Is this strap suitable for heavy aluminum ingots? Yes. As the engineer who designed it, I recommend the 2512 for heavy aluminum ingot bundling — the 11760 N break strength and thick 1.2 mm body resist the sharp, dense edges that cut thinner straps.
• Q: Can PET strap replace steel belt on brick and ingot bundles? Yes. The 2512 matches the holding jobs steel was used for, and adds rust-free, non-sparking, burr-free handling without staining your goods.
• Q: Do you supply manual-use strap as well? Yes. Green and black hand-use PET strapping can be customised, alongside automatic-machine rolls.
• Q: Can you customize width, thickness and color? Yes. We support logo printing and special thickness requirements, and offer models such as 1608, 1609, 1910 and 2510, in 20 kg or 25 kg coils.
