We'd like to compare the advantages and disadvantages of different building formwork systems from different views in table.

Table 1: Advantages and Disadvantages of Formwork Systems
Items Plywood formwork Steel formwork Aluminium formwork Remarks
Material 18 mm thickness plywood 5–6 mm thickness steel plate 4 mm thickness 6061 - T6/6082 - T6 aluminium alloy light weight, high strength
