Material
Manufactured from galvanised steel.
Hole Size
The actual hole is slightly larger than the nominal size to fit comfortably over the spiral tube:
Actual hole diameter = nominal size + 4–6 mm.
Example: a 150 mm nominal diameter results in a hole of about 154 mm.
Plate Size
The overall plate dimensions depend on the nominal hole size:
For nominal holes up to 250 mm: plate size = nominal hole size + 100 mm.
For nominal holes 300 mm and above: plate size = nominal hole size + 150 mm.
Examples:
150 mm nominal hole → plate measures 250 × 250 mm overall.
400 mm nominal hole → plate measures 550 × 550 mm overall.
