Packaging Characteristics
Roll Protection: The inner core of the roll material is made of steel or paper tubing, with corner guards or angle irons added to the edges; the surface is covered with moisture-proof paper or PE film, and rust-preventive oil can be applied as needed.
Securation Method: High-strength steel strapping is used for binding; wooden pallets or trays can be used if necessary.
Bundling (Optional): Thin rolls can be bundled into multiple rolls, separated by separator paper to prevent scratches, and covered with a plastic film for protection.
Transportation Methods
Sea Freight: Use 20-foot/40-foot containers, securely secured with wooden wedges.
Rail Transport: Flatbed truck or rail transport, secured with chains or brackets.
Handling and Storage
Use coil hooks, lifting devices, or C-frames to prevent dragging.
Roll materials should be stored upright to prevent deformation and rust.
Store in a dry, well-ventilated place, and do not place them too high.
Stable cooperation with shipping companies such as MSK, MSC, COSCO efficiently logistics service chain, logistics service chain are we to your satisfaction.
We follow the standards of quality management system ISO9001 in all procedure, and have strict control from packaging material purchase to transport vehicle scheduling.
1. What is non-oriented electrical steel coil?
Non-oriented electrical steel coil is a type of silicon steel with good magnetic permeability and low iron loss. It conducts magnetically uniformly in all directions and is widely used in electrical equipment such as transformers, motors, and generators.
2. What are the common thicknesses and widths?
Thickness: Typically 0.27 mm, 0.30 mm, 0.35 mm, etc. (customization available upon request)
Width: 600 mm ~ 1250 mm (customization available)
3. What are the surface treatment options?
Insulating varnish treatment (surface coating): Used to reduce eddy current losses.
Rust-preventing oil coating: Prevents oxidation during transportation and storage.
VCI protective paper or PE film packaging: Moisture-proof and corrosion-proof.
4. What are the packaging methods?
The inner core of each coil is made of steel or paper tubing.
The rolled edges are secured with corner protectors and steel strips.
The outer layer is wrapped with moisture-proof paper or plastic film. Small coils can be bundled into sets.
5. Is customization possible?
Yes, thickness, width, coil weight, surface treatment, and packaging can be customized according to customer requirements.
