Mesh to micron conversion
Soft nylon mesh from Switzerland
Micron sizes: 1, 5, 11, 15, 20, 25, 45, 50, 60, 73, 75, 90, 100, 120, 125, 150, 220, 225, 250, 308, 310, 350, 425, 500, 670, 700, 750, 1000, 1600
All these rolls are 10 metres x 1.02 metres
Base Material Variations
Basically there are four suitable synthetic fiber forming materials or polymers high density polyethylene (HDPE), polypropylene, nylon and polyester.
HDPE plastic net (hexagon mesh)
HDPE (high density polyethylene) mesh is used in various screening applications such as during water changes. Rolls are either 30 metres x 0.9 or 30m x 1.2, depending on the mesh size required.
Mesh sizes in millimetres: 2, 3.8, 10, 13, 20, 24, 27, 40, 47, 50. All plus/minus 0.5 mm.
For the manual grading of fish fry, we supply bowl shaped stainless steel graders, 39 cm diameter and 18.5 cm deep. 19 different mesh sizes for fish sizes from 0.9 cm to 15.1 cm
This is suitable for species such as grouper and designed to prevent damage to fish.
Stainless grading sieve - line design
This design prevents fry getting stuck in the mesh during grading. Stainless steel construction is resistant to seawater corrosion. These meshes come in 17 mesh sizes for fish of between 2.4 and 18 cm. These have been used on species like bass and milk fish.
