Products M400 For small curvature radii The M400 is made for the lowest curvature radii, and usually the lowest load per sq m. Typically used for internal facades, boat hulls, and wind turbine blades. M800 For medium curvature radii The M800 is the mid-level adaptive mould, used as an all-round solution with the ability to obtain high square meterage (>10 sq m) and relatively low curvatures of 800 mm or less. Typically used for exterior cladding panels and moulding the sides for large casting. M1200 For large curvature radii The M1200 was developed to support heavier loads, and higher curvature radii. It can handle up to 16 cms thick layer of wet concrete. Typically used for large building exteriors such as airports, museums and stadiums.
