A3 Rewritable Magnetic Sheet

This flexible magnetic sheet measures:

• Width: 297mm
• Length: 420mm
• Thickness: 0.8mm
• Format: A3
• Surface: White Gloss
• Product Code: NF04

The full A3 format provides a relatively large writing and display area while retaining the flexibility and removability of magnetic sheeting.

It can be used as a complete A3 sheet or cut into smaller magnetic labels, strips, signs or custom shapes where required.

White Gloss Rewritable Surface

The white gloss surface is designed for applications where information needs to be written, changed and updated.

This makes the sheet particularly useful for information such as:

• Product names
• Stock information
• Locations
• Dates
• Tasks
• Staff names
• Instructions
• Schedules
• Temporary notices
• Workflow information
• Equipment identification

Rather than replacing an entire label or sign whenever information changes, the rewritable surface allows the magnetic display to be reused.

Writing and cleaning performance can vary according to the writing instrument used. Always test the intended marker and cleaning method on a small area before widespread use.

Reusable Magnetic Labels and Signs

One of the key benefits of rewritable magnetic sheeting is the ability to create temporary or frequently updated signage without permanently attaching labels to a steel surface.

The sheet can be positioned on compatible ferromagnetic surfaces and then:

• Removed
• Repositioned
• Relocated
• Updated
• Reused

This makes it particularly suitable for environments where layouts, stock, staff, schedules or information change regularly.

Warehouse and Inventory Labelling

The NF04 rewritable magnetic sheet is well suited to warehouse, logistics and inventory management applications.

It can be used to create magnetic identification for compatible steel:

• Shelving
• Racking
• Cabinets
• Storage systems
• Equipment
• Work areas
• Stock locations

Magnetic labels can be particularly useful in dynamic warehouses because they can be moved when storage locations or inventory arrangements change.

Production and Manufacturing

In manufacturing environments, rewritable magnetic sheets can provide a flexible method of displaying changing production information.

Potential uses include:

• Production status
• Work orders
• Job identification
• Equipment status
• Workflow information
• Quality-control information
• Temporary instructions
• Scheduling
• Maintenance notices

The sheet should only be positioned where it will not interfere with machinery, moving components, safety systems or required permanent signage.

Office and Planning Applications

The white gloss surface can also be used for reusable information displays in suitable office environments.

Potential applications include:

• Staff schedules
• Project planning
• Task allocation
• Meeting information
• Temporary notices
• Workflow boards
• Storage labels
• Equipment identification

Where the underlying surface is compatible ferromagnetic steel, the sheet can be moved without requiring adhesive installation.

Classroom and Educational Applications

Rewritable magnetic sheets can also be useful in classrooms and training environments.

Potential applications include:

• Lesson activities
• Reusable labels
• Classroom organisation
• Timetables
• Learning exercises
• Demonstration materials
• Magnetic signs
• Student activities

The sheet can be cut into smaller pieces for customised educational resources where appropriate.

Cut-to-Size Magnetic Sheet

The 297mm x 420mm A3 sheet can be used whole or cut into smaller pieces using suitable equipment.

Custom pieces may include:

• Magnetic strips
• Shelf labels
• Name labels
• Equipment labels
• Small signs
• Identification markers
• Custom shapes

When cutting, use suitable tools and safe cutting practices. Test the finished piece on the intended surface before producing larger quantities.

How Flexible Magnetic Sheeting Works

Flexible magnetic sheeting contains magnetic material incorporated into a flexible matrix, allowing the sheet to attract compatible ferromagnetic surfaces while remaining substantially more flexible than rigid permanent magnets.

Unlike a rigid neodymium magnet, flexible magnetic sheeting is designed primarily for applications such as:

• Labelling
• Signage
• Displays
• Identification
• Organisation
• Lightweight magnetic attachment

It should not be expected to provide the same magnetic strength relative to size as a rigid rare earth magnet.

Compatible Magnetic Surfaces

The magnetic side is designed to attach to compatible ferromagnetic iron and steel surfaces.

Suitable surfaces may include:

• Mild steel
• Magnetic steel shelving
• Steel cabinets
• Compatible warehouse racking
• Steel display surfaces
• Ferromagnetic equipment housings

It will not magnetically attach directly to non-ferromagnetic materials such as:

• Aluminium
• Copper
• Brass
• Plastic
• Timber
• Glass

Many stainless steel grades may also provide weak or negligible magnetic attraction and should be tested before use.

Magnetic Performance and Surface Contact

Flexible magnetic sheeting generally provides its best practical attraction when positioned directly against a clean, smooth and compatible ferromagnetic surface.

Performance can be reduced by:

• Paint thickness
• Protective coatings
• Dirt
• Surface irregularities
• Gaps
• Curved surfaces
• Weakly magnetic target materials

Always test the sheet on the intended surface where secure attachment is important.

Not Compatible with Glassboards

Please note, this product alongside all flexible magnetic products are not compatible with glassboards.

Glassboards create a physical gap between the flexible magnetic material and the underlying magnetic or steel component. Flexible magnetic products generally do not provide sufficient magnetic attraction across this distance.

For this reason, products specifically designed for magnetic glassboards should be selected instead.

Rewritable Magnetic Sheet vs Adhesive Labels

Unlike conventional adhesive labels, this magnetic sheet does not require adhesive to attach to a compatible ferromagnetic surface.

This provides several benefits for changing environments:

• Easier repositioning
• No adhesive residue from normal magnetic attachment
• Reusable installation
• Faster relocation
• Convenient updates to layouts and information

Adhesive labels may still be preferable where the mounting surface is non-magnetic or where permanent attachment is required.

Rewritable Magnetic Sheet vs Rigid Magnets

Flexible magnetic sheeting and rigid magnets serve different purposes.

Rewritable flexible magnetic sheets are particularly suited to:

• Signage
• Labelling
• Information displays
• Organisation
• Large surface coverage
• Cut-to-size applications

Rigid neodymium magnets generally provide:

• Much higher magnetic strength relative to size
• Concentrated magnetic holding
• Greater suitability for mechanical holding applications

The NF04 is therefore designed primarily as a flexible magnetic display and labelling material rather than a high-strength holding magnet.

Care and Use

To help maintain the magnetic sheet and writing surface:

• Keep the magnetic face clean
• Apply to clean, smooth compatible steel where possible
• Avoid sharp folds or creases
• Store flat where practical
• Test writing instruments before widespread use
• Test cleaning methods on a small area
• Avoid abrasive cleaning that could damage the gloss surface
• Remove writing regularly rather than allowing markings to remain indefinitely where staining may be a concern

Please Note

This product is a Rewritable A3 Magnetic Sheet measuring 297mm wide x 420mm long x 0.8mm thick with a white gloss surface, identified by product code NF04.

The sheet is designed primarily for reusable magnetic labelling, signage, identification and information displays on compatible ferromagnetic surfaces.

No specific pull force, magnetic flux density, magnetic material grade, marker type, cleaning chemical compatibility or temperature rating has been supplied and these specifications should not be assumed.

Actual magnetic attachment depends on the target material, surface condition, coatings, available contact area and any gap between the magnetic sheet and target.

Test the intended writing instrument, cleaning method and mounting surface before use where appearance or reliable attachment is important.

Please note, this product alongside all flexible magnetic products are not compatible with glassboards.
