What Is A Magnetic Chamfer?
Magnetic Chamfer strips are used to create chamfers during the precast concrete process. When using side forms without chamfers, if chamfers are required, chamfer magnetic strips can be used flexibly. The chamfering strip has high strength, does not slip, and is not easily deformed. It is embedded with strong magnets such as ammonium iron boron, and can be accurately positioned at any position of the bottom mold or side mold. The chamfering strip can be reused, saving costs, and is extremely effective in actual production and use. Great convenience.
According To The Material Of The Product, Magnetic Chamfer Can Be Divided Into Three Types:
1) Rubber Magnetic Chamfer (Most Flexible)

4) PVC Chamfer (smooth; the formwork removal is convenient)
Besides Magnetic Chamfers, We Also Supply Plastic PVC Concrete Chamfer Material for Precast Concrete Elements Production.
90-durometer plastic PVC concrete chamfer material is excellent in long lines and straight uses and can also be used in a majority of large radius curved and round applications.

The main function of the PVC round concrete chamfer is to turn the concrete right angle into an arc angle. Before the concrete pouring, the corner line can be fixed at the internal corner of the formwork, which can be fixed by the special row nails for decoration. PVC circular arc chamfering line, R25 is a circular arc radius 25mm angle line, used for the main transformer foundation and other large foundations;
PVC circular arc chamfer line R20 is a 20 mm circular arc radius corner line, which is used for the general foundation. The concrete arc angle line is mainly used for concrete products. When the mirror concrete is used for a fillet, the outer part is fixed with wood formwork. Beams, columns, and the upper side of the cable trench are widely applied in thermal power plants or high-pressure power stations in infrastructure construction.
PVC Concrete Chamfer Product Advantages
1. Stable quality, excellent physical performance, can be used repeatedly.
2. Bright color, high gloss.
3. It is easy to process the finished products with a high yield.
4. The surface of the product is smooth, the formwork removal is convenient, and the fillet is beautiful and generous.
5. After composition, it can save cost compared with metal material and has the advantage of high quality and low price.

According to the cross-sectional shape of the Product, the magnetic chamfer can also be divided into three types:
● Triangle magnetic chamfer
Please see the below cross-section picture, you will find that the strong neodymium magnets can be inserted at three different positions: two sides and the bottom.
● Trapezoid Magnetic Chamfer
● Special shape magnetic chamfer (according to the customer's request)

The magnetic chamfer is one of the most useful and frequent accessories in the Precast Concrete industry.
Magnetic Chamfer is widely used for the attachment to steel shuttering surfaces and steel tables, for:
● Quick and clean formation of chamfers, beveled edges, drip molds, dummy joints, notches, and reveal on the corners and faces of concrete wall panels and some formwork's corners.
● Prevent the concrete overflow from the gap between the precast concrete casting table and side-formwork.
● And avoid the screwing or welding on the table or the formwork.
● And it finally improves the precast concrete element's production times and labor costs.

Magnetic Chamfer Features
①High Quality, Reusable, durable for more than 3 years with a service life, ensuring a nice payback on the original investment. Save money.
②Powerful magnets are embedded at the surface of the chamfer to provide maximum adhesion to any steel surface. For example, single-side magnetic steel chamfer offers more than 100 kg per meter strength. It won't be pulled out under normal use.
③Rubber magnetic chamfer, both sides magnetized, and Steel Magnetic chamfer available in single-side magnetized (50% magnet) or both-side magnetized (100% magnet).
④Easy to operate, quick to position, remove, and clean, quick and accurate positioning of exact beveled chamfers on the construction steel formwork table, and shortening the production timeline.
⑤ No open grooves to fill with the concrete. Securely, no screws, bolts, or welding are necessary, therefore preserving the surface finish to increase the lifetime
Both magnetic trapezoidal and triangular chamfer strips are available for clean chamfers and joints
Magnetic Chamfer Application
Magnetic chamfers are often used in the manufacture of concrete products, working with steel beds or steel faceplates and bulkheads that can be mounted to most types of precast rail-frame systems on the market.
The magnetic chamfer is required for the formation of the chamfered corner on the product to create an accurate aesthetic appearance of the corners of concrete products, and also eliminates bevel angles of concrete products from chipping. Can be easy to use the chamfered edges on concrete

How to Choose Single-Sided and Double-Sided?
Choose the single-sided magnetized option if attaching to one steel surface at a time, such as a steel table or steel faceplate. The double-sided magnetized option provides an extremely secure corner attachment when you're working with two adjoining sections of steel.
