Yes, most garden hardware fittings are made from galvanised or powder-coated steel, which resists rust and withstands rain, frost and UV exposure outdoors. Galvanised coatings protect the metal for years of ground and above-ground use. This makes them suitable for permanent fencing, decking and garden installations.

Choose garden hardware by matching the fitting to the post, timber or panel size and the load it must carry. For fence posts, measure the post cross-section (typically 70×70, 90×90 or 100×100 mm) and select caps, spikes or holders to fit. For decking and structures, pick connectors and anchors rated for the weight and the fixing method you plan to use.

Garden post supports and anchors are installed by driving them into firm ground, setting them in concrete, or bolting them to a solid base, depending on the model. Drive-in spikes suit stable soil, while concrete-in and bolt-down bases give greater stability for heavier posts. Position the fitting level and plumb before fixing the post in place.

Whether screws or fixings are included depends on the specific product, so check the item description before ordering. Many brackets and connectors have pre-punched holes designed for galvanised or stainless steel screws and bolts, which are sometimes supplied and sometimes bought separately. Using corrosion-resistant fixings is recommended for all outdoor garden hardware.
