Shuttering Magnet (Shuttering Magnet for Precast Formwork) Introduction
Precast concrete magnets are very popular in modern civil engineering. In the past 5 years, some conventional magnets were used to position and fasten the formwork, but considerable mechanical loads with a hammer were required, which destroy the surface of the expensive formwork tables and fragile neodymium magnet as well.
In order to facilitate the precast concrete formwork industry, GME is developing and manufacturing our own shuttering magnet to solve this problem successfully.
Our shuttering magnet also is known as button magnets and magnetic boxes. It is consists of a metal casing, a magnetic system, and an effective on/off button, which provides quick operation leading to improved efficiency when setting out and remove the formwork. Shuttering Magnet. And with customized adaptors, Shuttering Magnet provides an ideal solution for almost all kinds of precast concrete formwork structures and construction for wood, aluminum, and steel shutters.
All GME shuttering magnets have extraordinarily high magnetic power more 250 times than their dead weight. Among them, Shuttering magnet 1800KG and 2100KGS is a large size for steel precast concrete platform.
The GME shuttering magnet have an automatic system to activate and deactivate the magnetic field. By application of this precast magnet box, the working time and cost will be reduced and the same workers could produce more concrete walls in a shorter time. Under the same artificial conditions, the use of the shutter magnet system can increase the production capacity by 7 times
Key Benefits Of Shuttering Magnets:
1.Easy installation and effortless operation. Your workers could choose a fixed position at will and quickly build concrete formwork according to individual architectural design. Significantly save complexity and time and cost on the installation of magnetic formwork(up to 70%).
2.Universal use for mass production of concrete products, and piece different shape and size concrete elements of all forms on the same steel table. Excellent applicability, the same prefabricated formwork magnet can be adapted to different concrete formworks. You do not need to have a lot of different forms for different products. The same magnet can be used for different purposes and in different ways. You only need a set of magnets, adapters for different height boards, and a steel table. Your workers could contemporaneously build different concrete formworks at one time; even during the building process, your workers could adjust the concrete formwork.
3. Integrated threaded holes M12 and M16 to adapt formwork and customized adapters, to fix all kinds of side-formwork including wood, steel, and aluminum formworks, eliminates the need for welding, shuttering magnets does not damage the steel table. Avoid welding or bolting to the formwork table therefore preserving surface finish and reduce direct damage to the concrete platform in the working.

Why the magnet can create more 200 times stronger than its dead weight?
After a reasonable magnetic circuit design, multiple pieces of strong NdFeB magnet with the same magnetic pole are forcibly fixed in a relatively small space by screws. There is a Q235 magnetic permeable block between the magnets, to guide the repulsive force of the same poles in the same direction and perpendicular to the mold table. Multiple magnetic pole lines form a stable magnetic field and a very high magnetic holding force.

How to Pack a shuttering magnet, to meet with your requirement shipping by sea, by air/express, and by railway?
Your shuttering magnet will pack with a double-wall corrugated carton firstly and tight with a strong packing belt. Between cartons and shuttering magnet, between magnets, there is a high-quality foam plate to separate and protect products from scratch and damage.
1. By Sea, you have 2 packing options by sea.
1.1 Packing by Pallet
1.2 Packing by Strong Wooden Case.
This option looks more formal and beautiful. But it is more expensive 35USD per Case than option 1.
2. What should you pay attention to when shipping shuttering magnet by air?
By Air and Express such as FedEx, DHL, UPS, and TNT:
In international air/Express transportation, magnetic items are sensitive, and their magnetism will interfere with the safety of aircraft transportation. Therefore, the airline decided that all items containing magnetism need to be magnetically inspected.
So we need to magnetically shield the items so that the magnetism of the items meets airline standards. So packing needs to insert thick iron sheets or iron boxes between the foam and carton wall.
Friendly tips:
When magnetic items are shipped together with non-magnetic items, all items must be checked for magnetism.
The magnetic inspection report is a one-time report and is only used once. Next time, even if you use the same logistics channels for the same items, you still need to do a magnetic inspection and obtain the corresponding magnetic inspection report. Except for FedEx and DHL, they accept annual magnetic reports.
By Railway, we use the same packing standard to that of by air.
How to use the Shuttering Magnet:
It is very easy to use this product. Simply move the concrete magnet onto the precast concrete platform (or tray) and press the button.
Open the magnetic field:
Press the button by foot or rubber hammer.
Close the magnetic field:
Pry up the button by the lift lever (also known as the crowbar), the button can easy to be pulled up.
Tip: use 2 pcs tools together when removing more than 1000KG, in case of the lever bending
