Radius shaping

The FMK profile can easily be radially shaped rendering a good result down to a radius of 0.5 meter. We recommend pre-curving of the profiles for a radius within the interval 0,5 – 200 meters. With this the rail is easier to mount and aesthetically the result is always better. By pre-curving is meant that the tubes are rolled before galvanization and can be made in two different ways.

Radius shaping in the interval 0,5 - 12 meters is made by means of induction heating of the tubes.
Radius shaping in the interval 13-200 meters is made in a workshop in a machine.
An adjustment of the radius can also be made after galvanization. Our mechanics are equipped with specific curving tools (see picture) that are adapted to our profiles. With this tool the ultimate finish of the rail is done.

Repair

The tubular profile railing is built up by tubular profiles in different lengths. They are jointed to internal jointed sleeves. When changing damaged tubular profiles, a specific repair spare extension is used having a massive u-shaped protrusion provided with a number of smaller holes (see illustration 1). The small holes make it possible to feed the jointed sleeve into the closed profile.
When the damage to the rail is extensive and where tubes must be replaced, do the following: Cut off a damaged tube and demount the tubes and poles which are damaged. Thereafter, mount the rail again in the usual manner until one tube remains. Then follow the series of illustrations above.

1. The last tubular profile shall joint the rail again and for this a specific spare extension is necessary. 2. Check that the spare extension is running smoothly inside the profiles which are to be joined. If the spare extension is jammed, place a wedge in the U-shaped protrusion to widen the profile 3. Insert the repair spare extension into the profile next to the one that is to be affixed thereto.

4. Thereafter place the new profile into position next to the one with the spare extension. 5. Place the repair jointed sleeve so that half of the sleeve falls into a correct position in the new profile. The feeding is made through the holes that are meant for the bolts. 6. Finally, the bolts are pulled through the profile and the jointed sleeve, ending the repair work.
