Some precautions for the safe use of pesticides
Perforated Metal Mesh, (also named Perforated Sheet, Perforated Metal) refers to the metal sheet products with various
different holes on the surface. There are many kinds of punching wire mesh products.
Different shapes, different sizes of holes, can adapt to different needs.
Material: Stainless steel, low carbon steel plate, galvanized, PVC, cold rolled
coil, etc.
The types: pattern perforated sheet,
forming perforated plate, extra thick punching net, ultra thin punching mesh, micro
porous perforated sheet metal, wire cutting punching net, Laser punching net, etc.
Shape of Hole: Rectangular
hole, square hole, diamond hole, round hole, hexagonal hole, cross hole,
triangle hole, long round hole, long waist hole, plum blossom hole, fish scale
hole, pattern hole, five pointed hole, irregular hole, bulge hole, etc.
Use: Sound-absorbing
materials for ceilings and wall of buildings; Exquisite decorative board for
building staircase, balcony, environmental protection desk and chair; Machinery
and equipment protection cover, grille gorgeous, food, feed, mine mill sieve,
sieve screen, I-beam, stainless steel kitchen equipment, food cover, blue fruit
and other kitchen utensils, and shopping malls with shelves, exhibition
decoration, ventilation network for grain depot, football turf seepage water
filter and so on.
Size: 1.Thickness of coil: 0.2mm-1mm; Length:
20m
2. Diameter of hole: 1.5mm-10mm
3. Thickness of plate:
0.2mm-20mm;Width*Length≤1.5m*5m
4. Diameter of hole: 0.5mm-200mm
Hole
diameter:
Generally speaking, the aperture
size is approximately greater than or equal to the thickness of the plate,
which is in accordance with the principle of minimum pore diameter. The closer
the diameter of the hole to the thickness of the sheet, the greater the
difficulty of processing and the higher the processing fee.. In some raw
materials, the hole size can be less than the thickness of the plate.
Pitch
The pitch is
the distance between the middle of a hole and the other one, the nearest hole
in it. The middle distance is a way to represent the interval between holes,
and the other is the rate of opening. The essential meaning of the two
representations is the same. So you just need to identify one of them.
(1) 60 degree staggered row
Compared
with the former, the 45 degree plum blossom provides another choice for people.
Another
kind of round hole placement is straight row, straight row can also have a
variety of holes and opening rate, but it is the hole in the series of the
worst compressive strength.

2. When opening the pesticide packaging and weighing preparation, the operator should wear the necessary protective equipment.

Arrangement of holes:
(detailed picture explanation)
We can make all kinds of difficult passes and
patterns. Although special requirements for pass and pattern require a
specified processing fee, the quotation for the usual pass is quite reasonable.
60 degree staggered row is one of the most popular choices with its natural high strength and wide
aperture ratio and attractive appearance
(2) 45 degree staggered row
(3) Straight Row
