Soldiers are an important component in heavy-duty concrete wall forming. These 2.5-meter-long structures are made using strong materials like 50x50x6 mm M S slotted angles and 3 mm M S sheet. The soldiers are tied together to form parallel faces, which are then joined using wedge sets inserted through slots in the punched flat that forms the edge of the panel. This system provides stability and support to ensure the concrete wall is constructed with precision and strength.
