Flexible tube magnet strip is a magnetic assembly made by sealing multiple magnets inside a soft protective tube. Compared with rigid magnets, it offers better flexibility, safer surface contact and easier handling for applications that require bending, repeated positioning or contact with irregular surfaces.

The outer tube can be made from PVC, rubber or silicone, with standard colors such as black, red, blue and yellow. Custom Pantone colors are also available. The internal magnets can be adjusted according to required holding force, tube length and working environment.

This product is suitable for industrial holding, tool organization, display fixtures, DIY magnetic products, packaging accessories, warehouse labels and custom magnetic assemblies.

Manufacturer’s Suggestions

For this type of neodymium magnet assembly, the final performance depends on more than magnet grade. The tube thickness, distance between magnets, contact surface, installation depth and magnetic direction all affect the actual holding force.

For accurate quotation and sample development, we suggest providing the following information:

• Product drawing or sample photos

• Required tube length and diameter

• Magnet size or target magnetic force

• Magnet quantity per piece

• Required magnet spacing

• Polarity direction or attraction method

• Final installation position

• Order quantity and packing requirement

If you are not sure which magnet size is suitable, we can help evaluate based on your product structure.

Our cylindrical neodymium magnets are manufactured under a strict quality management system to ensure consistent performance and reliable quality. Our factory is certified with ISO 9001 Quality Management System, ensuring standardized production processes and strict quality control from raw materials to finished products.

FAQ

Q1: Can the tube color be customized?

Yes. Standard colors include black, red, blue and yellow. We can also produce custom colors according to Pantone code or physical samples.

Q2: Can you adjust the magnetic force?

Yes. Magnetic force depends on the internal magnet size, grade, quantity and spacing. We can adjust the structure according to your application.

Q3: Is it suitable for outdoor use?

It depends on the tube material and magnet protection. For long-term outdoor use, we recommend confirming the temperature, humidity and exposure conditions first.

Q4: Can the length be customized?

Yes. We can produce different lengths according to customer drawings, samples or application requirements.

Q5: What is the difference between this product and magnetic tape?

Magnetic tape is usually flatter and weaker. This product uses magnets inside a protective tube, so it can offer stronger holding force and better surface protection.
