Product Options

Type:

- BN-G:

  • Has closed, punched dimple indentations, pressed upwards in the top surface. Offers high anti-slip resistance.
  • Perforation type: Closed and raised punched dimples.
  • Open area: 0%.
  • Size: Widths of 150 mm, 200 mm and 250 mm; lengths of up to 10 000 mm; heights of 30–150 mm.

- BN-GA:

  • Includes a mixture of closed punched holes facing upwards, and conical drain holes facing downwards. Grating has no sharp edges on the top surface, and can be walked on easily without the need for footwear. Water drains easily through the holes, so that no hydroplaning can occur.
  • Perforation type: 8 mm punched holes, 10 mm ball proof.
  • Open area: 2.4%.
  • Size: Widths of 150 mm, 200 mm and 250 mm; lengths of up to 10 000 mm; heights of 30 mm, 50 mm, 75 mm, 100 mm, 125 mm and 150 mm.

- BN-O:

  • Similar to BN-OP, with punched holes, which are pressed downwards. Provides increased drainage performance, and light and air permeability.
  • Perforation type: 8 mm punched holes, 10 mm ball proof.
  • Open area: 5%.
  • Size: Widths of 150 mm, 200 mm and 250 mm; lengths of up to 10 000 mm; heights of 30 mm, 50 mm, 75 mm, 100 mm, 125 mm and 150 mm.

- BN-OD:

  • Plank with two different hole sizes; the holes punched upwards have a diameter of 14 mm (to allow quicker drainage), while those punched downwards have a diameter of 7 mm.
  • Perforation type: 8 mm punched holes, 10 mm ball proof.
  • Open area: 27%.
  • Size: Widths of 150 mm, 200 mm and 250 mm; lengths of up to 10 000 mm; heights of 30 mm, 50 mm, 75 mm, 100 mm, 125 mm and 150 mm.

- BN-OF:

  • Fire retarding, provides an alternative to conventional coverings. The planks have an outward edge to one underside edge, achieving an approximate support area of 20 mm, and both the short edges come with closed sides.
  • Perforation type: 8 mm punched slots, 10 mm ball proof.
  • Open area: 5%.
  • Size: Widths of 150 mm, 200 mm and 250 mm; lengths of up to 10 000 mm; heights of 40 mm, 50 mm, 75 mm or 100 mm.

- BN-OP:

  • Similar to BN-O, with double the amount of drainage holes. Provides increased drainage performance, and light and air permeability.
  • Perforation type: 7 mm punched holes, 10 mm ball proof.
  • Open area: 7.5%.
  • Size: Widths of 150 mm, 200 mm and 250 mm; lengths of up to 10 000 mm; heights of 30 mm, 50 mm, 75 mm, 100 mm, 125 mm and 150 mm.

  • Perforation type: 19 mm punched holes, 20 mm ball proof.
  • Open area: 32%.
  • Size: Widths of 150–400 mm; lengths of up to 10 000 mm; heights of 30–150 mm.
