Magnet-based formwork solutions offer quick and easy handling during shuttering and demoulding, which has a positive effect on production speed. The magnets hold the formwork securely in place. Adhesive or welded joints be-come unnecessary, which means that work can be carried out in a way that is gentler on the material. More than 20 years ago, Ratec launched the Standard Pro Magnet Box, or SPB for short (in the USA: KPB Klacker Power Box), and with it introduced the switchable magnets into the precast plant. Today, the SPB is used for formwork fastening in numerous precast concrete plants worldwide.
Reliable adhesive force
According to the manufacturer, the design with magnetic suspension, spring mechanism for activation and powerful built-in magnet ensures that no air gap can occur between the magnet and the pallet when activated, which would impair the adhesive force. The reliably strong magnetic force holds the formwork securely in place and prevents it from being moved unintentionally. At the same time, the magnetic suspension inside the box ensures that the integrated magnet floats when not activated, allowing the SPB to be moved easily and positioned precisely.
Patented built-in magnet as a basis
Standard magnets from the Pro-Magnet series are used in all RATEC magnet boxes and formwork systems. The company's own in-house magnet production in Germany allows it to tailor the magnets to the exacting requirements of its customers and thus realise numerous special solutions. In addition to the tried and-tested standard variants of the built-in magnets with adhesive forces of 450, 900, 1,350, 1,800 or 2,100 kg, Ratec can also implement other designs and magnet strengths as required, or adapt the installation components structurally without losing adhesive force, for example for particularly narrow shutters. High performance neodymium magnets are used for the Pro-Magnet series. Stainless steel bandages and various coating steps and processes make the magnetic core extremely corrosion-resistant. Ratec's extensive know-how in the field of magnet design and application enables it to perfectly meet every customer-specific requirement with precision.
Low workload
The Pro-Magnet is activated by a foot click or rubber mallet, thus fixing the magnet box firmly to the steel formwork surface. Even if a tool is required to release the magnets, time and effort is saved because the integrated adhesive force is reliable and thus the number of magnets required can be minimised over the formwork length.
Flexibility
The standardised hole spacing of the screw connections for attachments and adapters on the magnet box ensures that the magnet boxes can be used flexibly in the long term. Among other things, the SPB is also the basis for the form-work systems Easy Form, MST (Modular Formwork Beam) and PSV (Pro System Vario), which, in addition to the magnet box, provide a modular system of standardised components that offers a flexible formwork solution for most applications.
Wide range of accessories
Another useful addition is a set of attachment brackets, which are available in different heights. With 2- or 3-sided combination angles, recesses in particular can be formed very well. Another category consists of adapters for holding down the formwork skin, either with a fixed height or as a variant with a hold-down bar to which a profile hold-down can be securely clamped in a height-adjustable manner.
Special solutions for radius formwork, for stairs or for welding on a steel formwork skin are also part of the company's extensive repertoire.
The SPB magnet box can also be used with repetitive element geometries to avoid re-adjustment. The HT stop adapter as an accessory for the SPB 900 (900 kg adhesive force) consists of a foldable stop bracket that is folded approx. 80 mm away from the formwork when stripping the formwork. When shuttering again, the same geometry can be produced with the adapter folded forward again without having to re-adjust.

Continuity for maximum customer benefit
The SPB can be used to form a wide range of elements, from planar solid elements with or without recesses, for both longitudinal and transverse shuttering, to stairs, columns and trusses (in combination with Easy Form and vertical supports), to volumetric elements such as cellar shafts (with Easy Form and vertical supports). In battery and module production, the SPB is also used to fasten Ratec's shrink window solution. Since its introduction, the SPB has proven itself in almost all areas of application. This makes it one of the most versatile solutions for forming precast concrete elements and a solid basis for formwork tasks.
