• the post according to the invention can also be used for erecting reindeer fences, sheep and cattle fences and so on.
• game fences for motor ways and high speed train lines and reindeer fences, sheep and cattle fences are suitable purposes as the post can be manufactured at the place there the fence shall be erected or can in a small scale be manufactured at several places close to the place or places where the fence shall be erected.
• the post according to the invention has triangular cross section but also posts of other sections, for example square section can be manufactured according to the invention.
• the side elements of the post according to the invention are at their side edges provided with edge sections and that the side elements are connected with each other by connection of the edge sections with each other.
• the edge sections are directed outwardly from the post. If the post is of triangular shape the edge sections form, seen from the outside of the post, an angle of 150° with the plane of the central section of the side element in question.
• the edge sections are connected with each other by means of riveting, especially punch riveting.
• the post can at its lower end form a point which for example is constituted by substantially triangular side elements having their side edges connected with each other, the sheet metal strips forming the side elements of the post merging into the triangular side elements forming the point.

• edge sections 8 provided by bending have a width of about 10 mm.
• the side elements 4 are connected with each other to constitute the post according to the invention by connecting the edge sections 8 with each other.
• This can be provided by means of the method shown in Fig. 3 wherein the edge sections 8 have been connected with each other by means of so called punch riveting.
• a punch riveting is a cold forming operation conducted by means of a die and a punch. Subsequent to the punch riveting operation the edge sections connected with each other have the appearance shown in section in
• Fig. 3 in the area of each rivet.
• the edge sections 8 Prior to the connection by punch riveting the edge sections 8 can be connected as shown in Fig. 4, i.e. by the fact that one of the edge sections 8 has a portion which is bent back and into which the other edge section 8 is introduced.

• the post 10 has three side elements 12, each having a central section 14, portions 16 angularly bent inwards therefrom and edge sections 18 connected with the portions 16 and extending outwardly at a right angle therefrom.
• This design provides that the section of the post is inscribable in a triangle with the central sections 14 coinsiding with the sides of the triangle and the points of the edge sections 18 positioned in the corners of the triangle.
• This design of the post makes it possible to anchor the post in the ground by positioning the lower end portion of the post in an upwardly open space of an anchorage element positioned in the ground, the space having a triangular cross section.
• the embodiment of the post according to the invention shown in section in Fig. 6 is at its central section of its side elements provided with a profile in the form of longitudinaly extending ridges and grooves 20 providing the side elements with a better bending resistance.
• the profiling of the side elements in order to provide the side elements with the bent edge sections and with the profiled central portion can easily be conducted by a light mobile rolling mill which can at a desired place form sheet metal strips to a desired profile.
• This is advantageous especial ⁇ ly when erecting game fences, cattle fences and so on where the erection of the fences take place over long distances and often far-_ away from built-up areas. This reduces the costs for transportations to a substantial degree.
• the sheet metal strips forming the side elements of the posts can, if desired, be formed with openings, lugs and so on before or after the profiling of the sheet metal strips, i.e. are provided with their bent up edge sections or profile at the central section, if any.
• Such holes, lugs and so on can be used for the connection of fence net, pivots for gates and so on.
