TECHNICAL SPECIFICATIONS

By using the available equipment we perform the following operations of profile optimisation.

 

1. BENDING CUT

This operation allows the profiles to be connected directly or through-hole interconnections.

 

2. DEEPENING

This operation is also called a pre-punched hole. Deepening is used when connecting frame profiles by closing and tightening with self-drilling bolts.

 

3. CUTTING OF PROFILE ENDS AT AN ANGLE

Cutting profile ends at a 45° angle ensures the possibility to place one profile into another at any angle.

 

4. MARKING

According to the designations provided in the design documentation, each frame element is numbered with non-washable paint by using a buil-in printer in the equipment. As a result, the frame is assembled as simply and easily as LEGO blocks.

 

5. SCREW HOLE

A machine tool knocks out a hole of a 13mm diameter, through which the plates/supporting elements (trusses) are connected with bolts, washers, and nuts.

 

 

6. TRIPLE HOLE

Used to interconnect, calibrate and/or align plates.

 

7. MOUNTING HOLE

It is also known as a technological hole. It is used at the beginning of construction works to insert electrical cables, water pipes, and other wiring installations and hide them in the walls or supporting elements of the building.

 

8. CRIMPING

During this operation, profiles of the same cross-section are inserted into each other; therefore, the perfect plane of the plates is preserved.

 

9. WALL CUTTING

In parallel with the crimping operation, a through-hole interconnection may be carried out.

 

All above-described operations are performed by punching, which protects the rolled surface cuts from damage. The steel used in the manufacturing process is covered with a dense protective layer of zinc (Z275 g/m2). At the contact points of a punching tool, an effect of enveloping the cut edges with zinc (diffusion) is formed. This cutting method, different from the thermal cutting of metal with grinding tools or electric saws, protects from corrosion.

This is the way how frame elements, i.e. y. vertical stands with bent profile ends, are manufactured. This bending makes it possible to make a solid perpendicular connection with the upper and lower straps of the plate. When shaping a strap, radial curvatures appear in the rolling points of fastening edges. Figure 1.3 shows how structural elements are inclined. This deflection is a technological advantage compared to traditional construction methods, which use profiling structures.

We manufacture products in accordance with Standards EN 1090-1, EN 1090-4, EN 10143, EN 10346, and EN 10162.
