Ι What Is Shuttering Magnet?
A shuttering magnet, also known as a magnetic box or box magnet, is a type of precast concrete magnet designed to secure formwork, side rails, or blockouts onto steel casting beds during the production of precast concrete elements.
Terms like “magnetic box” or “box magnet” come from the device’s rectangular steel casing, which houses a powerful magnetic array. This naming convention is common in the precast concrete industry, where products are often described based on their function and appearance rather than technical magnetic terms.
The device uses this magnetic array inside a durable metal housing to provide a strong, temporary hold without the need for drilling, welding, or mechanical clamping. This makes the shuttering magnet a damage-free alternative to traditional fixing methods.
