How Magnetic Chamfer Strips Work

Magnetic chamfer strips use powerful neodymium magnets to quickly and securely attach to steel or aluminum formwork, creating clean, precise chamfered edges in precast concrete.

Key Components

  • Steel profile: Provides the strong, durable frame
  • Rubber or steel body: Ensures a smooth concrete finish and protects the magnet
  • Embedded neodymium magnets: Deliver high magnetic force for a secure hold

Magnetic Force and Neodymium Technology

Neodymium magnets are known for their exceptional strength and durability. They generate a consistent pull force along the chamfer strip, allowing quick attachment and easy removal without damaging the formwork.

Magnetic vs. Traditional Chamfer Strips

Functie Magnetic Chamfer Strip Traditional Glued/Nailed Chamfer
Installatiesnelheid Fast (seconds per strip) Slow (requires adhesive or nails)
Herbruikbaarheid High (hundreds to thousands of uses) Low (often single-use)
Precision & Finish Excellent, no visible fixing marks Risk of damage or irregular edges
Formwork Damage None Possible damage from nails/glue

Magnetic chamfer strips save significant labor time, boost precision, and reduce material waste—making them the smarter choice for efficient, high-quality precast concrete projects.

Types of Magnetic Chamfer Strips Available

Magnetic chamfer strips come in various types to suit different precast concrete needs. The standard steel magnetic chamfer is the most popular choice, known for its durability and strong magnetic hold on steel formwork. For projects requiring more flexibility and lighter weight, the rubber magnetic chamfer offers excellent adaptability while maintaining a solid grip.

When it comes to profiles, you’ll find triangle en trapezoid chamfer profiles, each designed to create specific concrete edge shapes with precision. This variety lets you pick the right chamfer shape for your project’s aesthetic and structural requirements.

Step-by-Step Installation Guide for Magnetic Chamfer Strips

Installing magnetic chamfer strips on your concrete formwork is quick and straightforward, helping you save time and improve chamfer accuracy. Here’s how to do it right:

1. Preparation of Formwork

  • Clean the steel or aluminum formwork surface to remove dust, grease, or debris.
  • Make sure the formwork edges are smooth and ready for chamfering.
  • Choose the right magnetic chamfer bar size and profile for your project.

2. Positioning and Alignment

  • Place the magnetic chamfer strip along the formwork edge where the chamfer is needed.
  • Align carefully according to the desired angle (triangle or trapezoid profiles).
  • Check that the chamfer strip sits flush against the formwork for a perfect concrete edge profile.

3. Securing and Double-Checking Magnetic Hold

  • The embedded neodymium magnets in the chamfer strip will hold it firmly in place.
  • Gently test the magnetic force by trying to move the strip manually—if it slides, realign and press firmly.
  • This magnetic hold eliminates the need for glue or nails, speeding up installation.
  • For critical applications, confirm the pull force matches your project needs by referencing the magnetic strength specifications.

4. Removal After Concrete Curing

  • Once the concrete has cured properly, simply detach the magnetic chamfer strip by pulling it away from the formwork.
  • Because there’s no adhesive or mechanical fixings, removal is quick without damaging the chamfer or formwork.
  • Clean the strip before the next use to maintain consistent magnetic performance.

Concrete Type Dense or fast-setting concrete needs durable strips that withstand longer curing times and higher abrasion.
Profile & Size Triangle or trapezoid shapes should match your desired edge profile (e.g., magnetic triangle chamfer), and sizes must correspond to project specs like 15×15 mm or 20×20 mm.
Budget vs. Performance Balance cost with how often you plan to reuse the chamfer strips. Durable, reusable strips save money long term versus cheaper, single-use options.
