The SPADE anchor is manufactured in three materials (Galvanised Steel, Aluminium, and Stainless Steel) and in ten sizes. Hi-tensile steel versions are hot-dip galvanised. All SPADE anchors of the same size, regardless of the material they are made of, will work with the same efficiency.

The manufacturer of the SPADE anchor never refers to an anchor’s weight, but rather to its effective surface area. The remarkable efficiency of a SPADE anchor is due to the size and shape of its effective surface: SPADE anchors of the same surface area will have the same holding power, no matter the material of which they are made.
