Borders of standard perforated patterns

Edges of coils:

Unperforated borders along the edge of the coil can be specified to avoid broken longitudinal edges. This is generally recommended, especially for material installed with free edges at low levels, within reach of the public. These borders are available on request and the closest possible match to the requested border is determined considering the pattern of the perforation and the width of the coil. The right hand side border can be made equal to the left hand side border, or set differently.

Edges of coils:

Unperforated borders at the end of a sheet can be requested to avoid broken transversal edges.

The borders are calculated in the same way as above, by fitting the pattern within the length of the sheet and choosing the best match to the requested border. The top border can be set the same as the bottom, or differently.

Delivery formats

The standard round perforated elZinc® is available in the following standard formats:

Finishes
The full range of elZinc® finishes is available in all of the patterns.

Other information
The material is supplied with protective foil on one side.
Due to the self-protective qualities of zinc, the surface treatment is performed before perforation. This allows the use of more efficient coil coating methods during processing. On the edge of the holes a gray patina will form will form over time.
