✅ 【Superior Strength & Durability】
Heavy-duty steel with 1100 lbs break strength, outperforming PP and PET strapping. Roll specs: 12" coil diameter.
✅ 【Rust-Resistant for Outdoor Use】
Special blue-black surface treatment enhances rust resistance and durability, ensuring reliable performance even in outdoor environments.
✅ 【Heavy-Duty Applications】
Engineered for pallets, pipes, lumber, bricks, and other industrial loads—perfect for warehouses, logistics, and construction sites.
✅ 【Safe & Smooth-Edge Design】
Manufactured with rounded edges to reduce the risk of cuts and injuries; protective gloves recommended for safe handling.
✅ 【Tool Compatibility + US Support】
Works with popular tensioners and sealers, including A333 and Rockcub RCV5, and backed by reliable US-based service and support.
This steel strap works with our RCV4 and RCV5 manual strapping tools — not the RCV2, RCV3, or RCV9, which are built for PP/PET strap only.
These steel strapping rolls have an established sales history on Amazon (sold in several width/length combinations). See verified buyer reviews and ratings for the 5/8" x 330ft version on Amazon.
Free shipping to every address in the contiguous United States.
Smaller items — parts, accessories, strap and film — ship by UPS or FedEx with tracking. Large machines ship by freight on a pallet, and liftgate service is included at no extra charge: the driver lowers the shipment to ground level, so no loading dock or forklift is needed on your end.
Someone needs to be available to receive and sign for a freight delivery. Inspect the shipment for visible damage and note it on the delivery receipt before signing.
Alaska, Hawaii, U.S. territories and international addresses are quoted separately — email support@rockcub.com before ordering.
Rockcub machines carry a 1-year warranty, handled by our U.S. team rather than an overseas queue.
Returns are accepted within 30 days of delivery. If an item arrives defective, damaged or not as described, we arrange a free return and a full refund — no return shipping, no restocking fee. Other returns need the item unused and in its original packaging; return shipping and a 15% restocking fee apply.
Email support@rockcub.com with your order number to start either.
