This guide is for professionals and DIY enthusiasts looking to protect and finish their 71mm square fence gate posts. The key benefit is the robust, hot-galvanized zinc coating that offers superior rust protection, especially in damp garden environments. A potential consideration is that the black finish is a coating applied over the galvanization and may require specific paint for further decoration.

The primary purpose is to protect the top of a 71mm square fence gate post from water ingress, which helps prevent rot and decay, while also providing a decorative finish.
The hot-dip galvanization process coats the steel with a thick layer of zinc. This zinc acts as a barrier and a sacrificial anode, protecting the steel from corrosion, especially in damp outdoor conditions.
Yes, you can paint over the black finish, but it is recommended to use a primer specifically designed for galvanized metal surfaces first to ensure good adhesion and durability.
This cap is designed to fit 71mm square posts.
While the hot-dip galvanization offers excellent protection, the specific environmental conditions in coastal areas can be harsh. Regular inspection and maintenance may be required.
The obtained thickness of the zinc coating amounts to 80-90 micrometers (um), with a minimum requirement of 60 um.
The post cap is made from S235 steel with a silver galvanization layer, finished with a black coating.
Ensure you are using a 71mm square post. If the fit is slightly loose, consider using a small amount of exterior-grade adhesive or shims before securing with screws.
This may indicate damage to the galvanized coating. Clean the area, ensure it is dry, and apply a touch-up paint suitable for galvanized metal or a cold galvanizing compound.
Ensure the surface is clean, dry, and free from any grease or oil. Use a primer specifically formulated for galvanized steel before applying your topcoat.
Setup:
This post cap is designed to fit snugly onto a 71mm square fence gate post. It can typically be secured using appropriate exterior-grade screws or nails, depending on the desired permanence and the material of the post. Ensure the post top is clean and dry before fitting.
