Stretch Metal
Hook-On A(Type 1)
Stretch Metal from Hunter Douglas
is a highly versatile designer material
giving extra visual effects to ceilings.
It is very easy to customise ceilings
by varying the types of mesh, theirarrangement, the lighting andthe colour.

Hook-On A (Type 1)

AB1

PLANKS
Stretch Metal planks designed to
be installed on hook-on profiles.
This system is designed for corridor
applications without visible wall angle
profiles, creating a free-floating
impression. All individual panels areeasily demounted by lifting them fromthe hook-on profiles. The Type 1panels are made from finer mesh andbended over the edges. The edges are
re-inforced with spot welded angle
profiles on the long and short sides.
Stretch Metal planks are ideal forsolutions where either a high level of
acoustic absorption is required or wherevisual and physical transparency of theceiling is requested. The systems arealso ideal for solutions where regularaccess into the plenum is required.

ACOUSTIC PERFORMANCE
Using acoustic pads on top of theStretch Metal panels offers exceptional
acoustic performance. The thickness ofthe pads can be chosen depending on
the required acoustical values.
The acoustic absorption value can reach
αw 1 with an acoustical pad of 85 mm.

TRANSPARENCY
The tiles can be made from various
mesh types. This results in different
optical effects if the natural or artificial
light comes from the plenum. It is
important to realise that stretch metal
meshes do have a direction. Dependingon viewing direction the mesh appears
more or less open. This influences lightcoming through the material but also thevisiblity of installations in the plenum.
The physical transparency can also be
used for smoke extraction and sprinkler
operation in case of fire.

COATING
Stretch Metal tiles are all powder coated materials. Durable powder coatings forexterior use are optionally available.
COLOUR RANGE
The standard colour range consists of RAL and NCS colours, including chrome.
Other special colours are available on request.
­QUALITY
Our focus on quality ensures the highest standard of production process, material,machinery and finished product. The superior durability of Hunter Douglas products
translates into lower costs during the life cycle of the product due to longer life
expectancy and lower maintenance costs. Our company processes areISO 9001 certified.

FIRE BEHAVIOUR
HunterDouglas ® metal ceilings areclassified incombustible, and will
therefore not contribute to fires. Whenceilings need to protect the structural
integrity of a building, HunterDouglas ®
ceilings offer a wide range of practicalsolutions with regards to fire resistanceand fire stability. Further information isavailable on request.

INSTALLATION
It is necessary for all versions that qualitative suspension systems are used. The systems must be stable, aligned and leveledso that they comply with the requirements of the panels. For information on installation, refer to the applicable assembly
instruction leaflets.

Stretch Metal consists of metal sheet with diamond or square shaped
holes. The stretch metal material is made with a tool that simultaneously
cuts and stretches the sheets. As a result the mesh is created without
any waste of material.

STANDARD MESH TYPES:

LD6 (Fe) open area 40%, thickness 1.7 mm
dimensions: 6 x 3.5 - 1.1 x 0.8 - 1.6 kg/m 2

LS6 (Fe) open area 36%, thickness 1.7 mm
dimensions: 6 x 4.5 - 1.2 x 1.0 - 1.3 kg/m 2

MESH TYPES
Standard
The standard mesh types are a square mesh (LS) or a diamond shaped
mesh (LD) with a variation in openness of the mesh. The range starts
with the smallest LS6/LD6 up to LS16. All mesh types are available insteel, with types LS8 and LS12 also available in aluminium.

LS8 (Fe+Al) open area 54%, thickness 1.9 mm
dimensions: 8 x 6.0 - 1.2 x 1.0 - 1.7 kg/m 2

KeyLS10 (Fe) open area 57%, thickness 2.0 mm
dimensions: 10 x 7.0 - 1.5 x 1.0 - 1.3 kg/m 2

SpecialSeveral other mesh types are available on request, depending ontechnical requirements and availability. Hexagonal mesh, Round mesh andOrnamental meshes are examples of the possibilities.­
