Each wallboard comprises a frame (1) formed of an upper metal section bar, a lower metal section bar, a left metal section bar, and a right metal section bar.

The invention relates to a complex section (1) consisting of a metal section (2) covered with a metal foil (3).

Each door panel comprises an extruded metal section (18), and the part (14) is also an extruded metal section.

The sheath consists of a cut down size of metal section and the guide is formed in one piece with said metal section.

The resulting metal beam can be an I-section beam or a box section beam.

The invention relates to a method for the production of a new type of metal section.

This device consists of a metal section piece that acts as a prop (6).

The protective skirting (2) is made from extruded metal profile.

The invention relates to a metal profile having an elongated base section (2).

The standard length of the metal profile - 3 meters.

Furthermore, a thermocouple (35) is mounted in a cavity in the metal section (30).

The first part (3) is a metal profile (5), extrusion-coated on at least one side with a plastic layer (6) which increases the section modulus and is thus multi-layered.

The metal profile is then secured to the inner wall of the reactor container.

In one embodiment the metal section is formed from two components which engage with a friction fit to provide width-adjustment of the section to suit walls of different widths.

The support component may, for example, be a metal component.
