What kinds of shuttering magnet?

Types of Shuttering Magnets in Construction
Shuttering magnets are categorized based on their design, application, and magnetic activation method. Below are the main types used in formwork systems:

1. Standard Toggle-Type Shuttering Magnets
Design: Equipped with a manual lever or toggle switch to engage/disengage the magnetic force.
Function: Used for general formwork applications where steel-backed panels need quick clamping.

Common Uses:
Holding vertical wall forms in place.
Securing column formwork during concrete pouring.

Advantages:
Simple operation (flip the lever to activate).
Durable and reusable.

2. Push-Button Release Shuttering Magnets
Design: Features a push-button mechanism for instant magnetic engagement.
Function: Faster to operate than toggle-type magnets, allowing one-handed use.

Common Uses:
High-speed formwork assembly.
Situations requiring frequent adjustments.

Advantages:
Quick activation/deactivation.
Reduced worker fatigue.

3. Heavy-Duty Shuttering Magnets
Design: Built with reinforced steel casing and stronger magnetic cores.
Function: Used for large or heavily loaded formwork systems.

Common Uses:
Securing thick concrete walls or deep foundations.
Supporting heavy-duty steel forms in bridge construction.

Advantages:
Higher holding power for demanding applications.
Resistant to deformation under stress.

4. Low-Profile Shuttering Magnets
Design: Compact and slim for tight spaces.
Function: Used where standard magnets are too bulky.

Common Uses:
Narrow column forms.
Thin-wall concrete structures.

Advantages:
Fits in confined areas.
Lightweight yet strong.

5. Electromagnetic Shuttering Magnets
Design: Uses electrical current to generate a magnetic field (instead of permanent magnets).
Function: Provides adjustable magnetic strength and remote control capability.

Common Uses:
Automated or robotic formwork systems.
High-precision concrete molding.

Advantages:
Magnetic force can be fine-tuned.
Can be turned off completely without residual magnetism.

6. Modular Shuttering Magnets (Multi-Pole Design)
Design: Contains multiple magnetic zones for better load distribution.
Function: Prevents formwork distortion by evenly spreading clamping force.

Common Uses:
Large-panel formwork systems.
Curved or irregular concrete structures.

Advantages:
Reduces risk of formwork bulging.
More stable than single-point magnets.

7. Waterproof/Corrosion-Resistant Shuttering Magnets
Design: Sealed housing to prevent moisture or concrete ingress.
Function: Used in wet or corrosive environments.

Common Uses:
Marine construction (piers, seawalls).
Underground or water-retaining structures.

Advantages:
Longer lifespan in harsh conditions.
Resistant to rust and chemical exposure.

8. Custom-Designed Shuttering Magnets
Design: Tailored for specialized formwork needs (e.g., angled, curved, or extra-large forms).
Function: Used in unique construction scenarios where standard magnets don't fit.

Common Uses:
Architectural concrete (complex shapes).
Tunnel lining or precast segment molds.

Advantages:
Solves unconventional formwork challenges.
Can integrate with proprietary form systems.
