Anodized Aluminum Expanded Metal Mesh – Requirements of Mesh Design
for Roof Mesh Panels and Wall Panels Cladding, with Detailed
Anodizing Technical Requirements Applied for this special Expanded
Metal Cladding Panel.
3 mm natural anodized Aluminum expanded metal mesh
Aluminum alloy standard material is 1050.
Specified anodizing film thickness 25 micron (warranted for 25
General Requirements follow:
Ø Roof mesh with approximate panel sizes 1250mmX3110mm in two pcs,
and panels are shaped. The Shaped panels mean the panels not
rectangular, some of them are triangles and others are almost
rectangular but corners degree are 88 to 92 not 90 to 90.
Specified mesh pattern design for Roof Mesh Panels:
§ LWD= 120 mm
§ Strand Width= 15 mm
§ Inclination degree= 67°
Mesh pattern For Wall Mesh Panels:
§ LWD= 60 mm
§ Strand Width= 5 mm
§ Inclination degree= 67°
Physical test for roof panels of size 1250X1500mm is required to
check the performance loading.
General: Specifications for mesh, frame, anodizing and as per the
approximate quantities for standard and nonstandard panels.

ANODISING of Aluminum Expanded Metal Mesh:
Aluminum anodizing shall comply with BS 3987, unless specified
The color anodising process for the aluminum sheet metals:
Coloring of the anodic film shall be achieved by use of a two-stage
electrolytic process utilizing cobalt or nickel as the coloring
metal or by use of a single stage integral process. On no account.
shall anodic films coloured by the use of tin electrolytes be used.
Any proposal by the
Contractor for the use of an alternative coloring technique can
only be considered if the
anodiser confirms in writing that the alternative process will meet
all of the visual, physical
and documentary requirements detailed within the Specification.
evidence and samples will be required to prove that an alternative
colouring process will
provide an equal or superior standard of performance and life
Colour control limits shall be submitted as samples.
All aluminium alloys used for anoidizing or expanding of the metal mesh shall be selected to ensure that the finished
visual appearance of all components is identical.
expanded metal mesh facade Details as following:
i) The aluminum alloy for extrusions shall be grade 6063, or
acceptable equivalent, and for sheet material grade J57S, or
acceptable equivalent, and a certificate shall be obtained from
the material supplier stating the grade of material supplied.
ii) For expanded metal lath grade shall be 151EX, or acceptable
equivalent, and a certificate shall be obtained from the material
supplier stating the grade of material supplied.
e) Base metal batching shall be controlled in order that areas
match. Critical visible areas shall
be from a single batch. Agree base metal batching with the Client’s
Representative in advance of production.
f) Sample of base metal shall be submitted to the Client’s
Representative for acceptance prior
