80 Mil Magnetic Sheet with 3M Adhesive Tape STTMGN 8.5×11 2 Pack

Description

Product Overview

The 80 mil magnetic sheet from STTMGN is engineered for high‑energy magnetic performance while remaining easy to handle. Constructed from anisotropic flexible rubber, the sheet delivers a strong, consistent magnetic pull that can be reliably used on metal surfaces of varying thicknesses. Each sheet measures 8.5 × 11 inches, a standard letter size that fits easily into common workspaces, filing cabinets, and display frames. The 0.08‑inch (80 mil) thickness provides a balance between flexibility and durability, allowing users to cut, trim, or shape the material without compromising magnetic strength.

What sets this product apart is the integrated 3M adhesive tape backing. The high‑quality adhesive ensures a secure, long‑lasting bond to smooth surfaces such as walls, doors, and panels, while still allowing clean removal when needed. This dual‑function design eliminates the need for separate mounting hardware, reducing setup time and overall project cost. The sheet is supplied in a convenient two‑pack, giving users ample material for multiple projects or for creating larger magnetic assemblies.

Technical specifications include a weight of 9.6 ounces per sheet, a black color that blends discreetly with most industrial environments, and a composition that resists corrosion and wear. The product is certified under the STTMGN brand and carries the manufacturer part number Sttmgn‑80mil‑8511. With a customer rating of 4.7 out of 5 stars from 25 reviews, the magnetic sheet has proven its reliability across a range of applications, from DIY crafts to professional safety signage.

Usage

Designed for versatility, the 80 mil magnetic sheet excels in both creative and industrial settings. In a home workshop, hobbyists can cut the sheet to create custom fridge magnets, magnetic tool holders, or decorative wall art. The strong magnetic force holds lightweight objects securely, while the adhesive backing simplifies installation on any metal surface without drilling or screws.

In commercial and industrial environments, the sheet is ideal for producing safety signs, warning labels, and instructional displays. Facility managers can quickly affix magnetic warning signs to metal doors, equipment housings, or safety gates, ensuring compliance with occupational health and safety regulations. Because the sheet can be trimmed to exact dimensions, users can tailor each sign to fit specific mounting locations, improving visibility and readability.

Educational institutions also benefit from the sheet’s easy‑to‑use nature. Teachers can create interactive magnetic boards for classroom activities, allowing students to attach and rearrange magnetic pieces during lessons. The sheet’s durability ensures it withstands frequent handling, while the adhesive backing keeps the board stable on metal cabinets or lockers.

FAQ

Can the magnetic sheet be removed and repositioned?

Yes. The 3M adhesive backing is designed for strong initial adhesion while still allowing clean removal without leaving residue. For best results, allow the adhesive to set for at least 24 hours before repositioning. If you need to move the sheet multiple times, a light cleaning of the surface with isopropyl alcohol will help maintain adhesion.

What types of metal surfaces are compatible with this magnetic sheet?

The sheet works on most ferrous metals, including steel, iron, and certain alloys. It will not adhere to non‑magnetic materials such as aluminum, copper, or plastic unless a magnetic layer is added. For optimal performance, ensure the surface is clean, dry, and free of dust or oil before applying the sheet.

How thick can I cut the sheet before the magnetic strength is affected?

Because the sheet is 80 mil thick, you can safely cut it down to about 50 mil without a noticeable loss in magnetic pull. Cutting thinner than this may reduce the overall magnetic force, especially when used on heavier objects. Use a sharp utility knife or scissors for clean cuts, and always wear protective gloves to avoid injury.

Is the magnetic sheet suitable for outdoor use?

The sheet is resistant to corrosion and can tolerate moderate humidity, making it suitable for indoor‑outdoor applications such as garage organization or patio signage. However, prolonged exposure to extreme weather conditions, direct sunlight, or high temperatures may degrade the adhesive over time. For long‑term outdoor use, consider applying a protective coating over the adhesive side.

Can I combine multiple sheets to create a larger magnetic surface?

Absolutely. The sheets can be placed edge‑to‑edge to form a larger magnetic panel. The adhesive backing ensures a seamless bond between sheets, and the magnetic field remains continuous across the combined area. This is useful for creating large magnetic boards, vehicle signage, or custom display panels.
