  • PRODUCT DETAIL

The Flat Pot Magnet Without Hole presents a completely smooth, uninterrupted working face on both the top and bottom surfaces. There is no centre hole, no threaded bore, no countersunk hole, no boss, and no external stud of any kind – both faces of the magnet are solid, flat, and continuous across their entire diameter. Compared to pot magnets of the same outer diameter that feature a centre hole, this solid-face version delivers significantly higher holding force per unit area. When maximum magnetic adhesion is your top priority, this flat pot magnet is the ideal choice. Need a non-standard size or a different pull force?

Note: The pull force is the test value under ideal conditions (direct attraction to a clean, flat 5mm thick low-carbon steel plate). In actual applications, factors such as paint, rust, air gaps, and thin steel plates will reduce the breakwaway force.

Key Features

  1. Maximum Magnetic Flux Utilization:Because the magnetic surface has no holes, the entire surface is an effective adsorption area. The steel outer shell concentrates all the magnetic force on one surface, maximizing the attraction. Compared to perforated pot magnets of the same size, its adsorption force is significantly stronger.
  2. Durable structure: The permanent magnets are completely encased in a robust steel shell, effectively protecting the internal magnets from impacts and scratches, making them resistant to breakage or cracking. This design also allows them to withstand frequent attraction and separation operations.
  3. Ultimate installation flexibility: It does not need to be aligned with any holes during use and can be directly attached or slid on any position and in any direction on a ferromagnetic surface. This “place and use” feature makes it ideal for scenarios that require rapid deployment and adjustment.

Applications:

1. Temporary Outdoor Signage, Event Banners & Construction Site Notices 

Outdoor temporary signage on steel structures – construction hoarding steel panels, scaffold tube rosettes, steel container walls, and steel-framed temporary buildings – presents a surface that cannot be permanently drilled for conventional sign fixing. Regulatory signage, safety notices, directional signs, and promotional banners must be attached securely enough to resist wind load, rain, and incidental contact, but removed cleanly at the end of the project without leaving holes or residue.

2.Industrial Welding and Assembly

When welding or assembling steel components, fixtures are needed to hold the workpiece in place. Flat pot magnet can serve as magnetic fixtures, directly adhering to the steel workbench or workpiece, utilizing their strong magnetic force for fixation and positioning. Operators can place and adjust them “by hand,” without the need for wrenches or other tools. This “place and use” characteristic greatly improves production efficiency, especially in scenarios requiring frequent workpiece changes or welding at complex angles.

3.LED Ceiling Lights

When replacing or installing LED ceiling lights, flat, holeless neodymium pot magnets offer the absolute advantages of “zero-cost installation” and “non-destructive” installation. They attach directly to the iron base without any tools or drilling. Simply fix the magnet to the back of the light panel, and it will snap firmly onto the ceiling with a “click.” This not only greatly simplifies the installation process but also provides significant convenience for future inspection and maintenance.
