3. For enquiries and orders:
Queries can be avoided if you provide the following data (no. 1 – 10) or provide a
drawing or sketch, as shown in the example below (fig. 1): In the event of missing
data, we will select the best alternative for production.
1. Quantity
2. Material type, in acc. with DIN and/or material no.
3. Sheet external dimensions: thickness · width · length (mm)
( s · a1 · b1 )
4. Tolerances:
a) In acc. with DIN 24041
b) Acc. to fixed dimension in acc. with DIN 24041
c) Acc. to customer tolerances, which must be expressly confirmed by us,
otherwise according to b)
5. Specification of perforation acc. to DIN....
4. Calculating the weight of perforated sheets
a) For sheets with the least unperforated edges (see 4.):
b) For normal perforated sheets with larger edge widths:
c) For relatively small perforated areas:
Examples: 1.) Perforated plate 1.5 · 1370 · 3000 Rv 5 - 8 DIN 24041 St 1203 least unperforated edge on all sides according to formula a)
2.) The same sheet but with the following edges: long edge, left e₁ = 100 · front edge, top f₁ = 40 long edge, right e₂ = 80 · front edge, bottom f₂ = 119
according to formula b)
100 -A₀ G ≈ · s · a₁ · b₁ · γ [kg] 100 [mm] [m] [m] [kg/dm³]
100 -35.4 G = · 1.5 · 1.37 · 3 · 7.85 = 31.26 kg 100
100-A₀ a₁ · b₁G ≈ + - 1 · s · a₁ · b₁ · γ [kg] 100 a₂ · b₂
100-35.4 1.37·3G = + -1·1.5·1.19·2.841·7.85=34.30 kg 100 1.19·2.841

Specification or description of perforated sheets1. The following standards are used as a base:
DIN 4185 T2: Terms and symbols for perforated bottom plates, perforated sheets
DIN 24041: Perforated sheets, dimensions
2. Abbreviated specification of a perforated sheet
with perforation Rv in acc. with DIN 24041 e.g. :
sheet thickness (s)
sheet width (a1)
external length (b1)
round holes
staggered
hole width (w)
spacing (t) material
2 x 8 7 5 x 176 0 R v 5 - 8 D I N 2 4 0 41 - D C 01
6. For staggered perforation Rv, the “direction of feed”
or “direction of perforation”.
7. Width of the unperforated edges acc. to diagram below
(e₁, e₂, f₁,f₂). Please note: perforation field dimensions a₂ and b₂
must correspond to the master gauge for holes; therefore always
check whether x and y are whole numbers. See figs. 2, 3, 4 and 5.
Only then determine the edges. The edge width is always given
as a measurement between the edge of the sheet and the
external edges of the perforations in the rows of perforations
on the outer edge of the field of perforations.
(Never relate dimensions e and f to the centre of the perforation!)
8. Raw edge (always at the bottom if not given). For unusual sheet
shapes it is absolutely essential to indicate the raw edge.
9. Surface (low-grease, oiled, coated, etc.)
10. Delivery details (date, method of dispatch, etc.)
Note:Formula c) provides the theoreti-cally exact value, as opposed toformula b) where the deviation isless than 0.1 %, however. Easier to handle, formula b) therefore provides suffi ciently precise values, especially since the sheet thickness tolerances lead to substantially higher deviations. Formula a) leads to even greater discrepancies because it does not take the unper-forated edges into consideration. In the example shown opposite the deviation is 3.02 kg = 8.8 %, if example 2) is calculated according to formula a).
0.0052 ·π G = 1.37 · 3- · 355 · 172 · 1.5 · 7.85 = 34.28 kg 4
G = weight in kgs = sheet thickness in mma₁ = sheet width in mb₁ = sheet length in ma₂ = width of perforation field in mb₂ = length of field of perforation in mγ = gross density of material in kg/dm³ for steel γ = 7.85 for stainless steel γ = 7.85 for aluminium γ = 2.7

cut through the
perforation
Glossary “Narrowest unperforated edge” (least unperforated edge)
This depends on the type of perforation, the thickness of the sheet, the
tolerances of the external dimensions of the sheet and the manufacturing
tolerances in perforation. It is kept as narrow as technically tenable.
“Cut through the perforation”
means that the trimming cut is directed through the field of perforation,
thus creating an outer edge of the sheet which is not smooth but
interrupted by perforation cuts, thus presenting no unperforated edge
(see diagramm right).
Beginning and end of field of perforations
If no specific agreement has been made, the field of perforations
may begin and also end with incomplete rows of perforations for
technical reasons (see diagramm right).
Perforation profile
The perforations on the top of the sheet become slightly rounded in the
process and on the bottom a small ridge on the edges of the holes is un-
avoidable. The hole extends downwards slightly and the narrowest part
of the perforation profile is counted as hole width w.
“Direction of feed” of perforation; “direction of perforation”
For perforations in staggered rows (Rv) the position of the master gauge
for holes in relation to the sheet dimensions must be determined by the
“direction of feed”. Direction of feed means the direction of a perforation
whose rows of holes are obviously straight and where the distances
between the holes are always equal to the spacing. The direction of
perforation is at an angle to the direction of feed (see diagramm 1).
“Relative open area A₀”, also called "freespace sectional area”
“free clearance” or “open screen surface” is defi ned by DIN as
“proportion of perforation in %, related to a hole with half margin
widths”. This means that this theoretical value does not represent
the proportion of the open perforation surfaces related to the whole
sheet area including unperforated edges and zones. This must be
borne in mind when calculating sheet weights, air permeability, etc..

Whether a subtle backdrop or glaring eye-catcher,
modern architecture is difficult to imagine without
perforated metal sheets. Increasing numbers of
property owners and architects trust in this extra-
ordinarily versatile and exciting design element.

used almost universally, whether as façade cladding,
sun protection and screens, ceiling and wall panelling,
in trade fair stands or shop fittings or in furniture
design.
Are you looking for a fast and reliable partner who can
provide customized perforated metal design exactly
to your specifications? Then take the benefits from our
longstanding project experience and take advantage
of our own development department and in-house
machine tool construction!

The interplay of design-orientated transparency and
strength is what has increasingly made perforated sheets
from SCHÄFER a major stylistic element in modern
architecture.
Through their own particular aesthetic, perforated sheets
attract attention and can represent either the dominant
feature or, at the same time, a more discreet expression
of form and shape. The formability and great processing
potential of aluminium and steel opens up an almost
unlimited range of application possibilities.

Sun protection
Perforated metal sheets can cover an incredibly wide
range of functions, such as providing rooms with air-
conditioning and shade. As innovative sun protection
screens or translucent panelling, they are an ideal
solution for uniting function and design.

Noise reduction
The sound absorbing effect they provide, make perfo-
rated sheets the ideal material for noise reduction.
Adjustable lamellas enable sound protection to be
adapted to any given conditions. Noise protection walls
are highly effective in reducing traffic noise and tailor-
made roof systems can prevent unwanted acoustic
interference.

Ceiling and wall panelling
Perforated sheets lend themselves to a modern, timeless
kind of design, which highlights objects by giving them
a clear, linear definition.
We supply perforated metal sheets in various materials
and with individual perforation patterns designed to
match each specific application.
These different perforation patterns can then create an
aesthetic effect that is subtle and reserved or blatant and
direct.

Functional interior design
Room climate, acoustics and ambience – designing
rooms combining a pleasant atmosphere with func-
tional optimization is a real challenge.
Perforated sheets provide room designers and interior
architects with a creative and stylistic medium that
can adapt to spatial and design structures and,
through their countless perforation patterns, can also
create impressive design highlights.
On top of this, perforated sheets are perfectly suited
to a range of technical roles in the fields of ventilation,
lighting, or sound absorption.

Climate control and ventilation systems
Because perforated metal sheets are, by their very
nature, permeable, they are ideal for use in rooms
requiring climate control and ventilation. The great
advantage is that they perform this function almost
invisibly, as the perforated sheets are primarily
perceived as a design element.
This enhances the room’s appearance, giving it a
distinct peace and clarity of design. The variable size
and positioning of the perforations as well as the
shaping of the sheets themselves allow the perfect
implementation of functional, aesthetic solutions.

Displays and retail fittings
An impressive appearance combined with the robust-
ness to withstand the strains of intensive daily use are
the outstanding hallmarks of perforated metal sheets,
especially in the construction of exhibition displays and
shop fittings.
The materiality and surface quality guarantees a particu-
larly high-class appearance, while elements such as
perforated metal display tables or shelving units are
extremely robust and easy to keep clean.
The variety of the sheets‘ perforation patterns and
shaping possibilities give rise to a vast potential of
individual styling and design.
