The 4000 lbs (1800 kg) pulling force shuttering magnets, also known as 1800 kg vertical tension precast concrete magnets, are mainly used in the production of precast concrete products. These shuttering magnets can effectively hold the work pieces in place, improve the construction efficiency and ensure the stability of the formwork during the concrete pouring process due to their strong magnetic properties. Shuttering magnets are widely used in a variety of precast concrete building and construction projects, including but not limited to the production of concrete wall panels, columns, beams and other concrete elements.
