Product Options

Material:

- Standard fabric:

The standard door-leaf fabric is a single sheet of heavy duty vinyl-coated polyester. The fabric is resistant to mechanical abrasion and sparks generated from mechanical processes such as welding. The standard fabric is available in nine standard colours, however other colours are available on request.

- Arctic fabric:

The arctic fabric replaces the standard fabric in environments where the temperature can be as low as -45ºC. It is only available in blue (RAL 5010).

- Sound-reduction fabric:

The sound-reduction fabric is for use in environments where the transmission of sound through the door must be reduced. It is installed on both sides of the door leaf.

- Heat-resistant fabric:

The heat-resistant fabric replaces the standard fabric on the inside of the door leaf when there is a requirement to contain heat and/ or chemical hazards. It is available with three different coatings dependant on the environment where it is going to be used.

- Security fabric:

The security fabric is for use in environments where security is important. It is similar to the standard fabric with the addition of galvanized steel wires inside the fabric. It is installed on both sides of the door leaf behind the standard fabric.

For further details regarding specific fabric properties, consult manufacturer's literature.
