Stretch Metal
Hook-OnSafety LoopExterior
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 Safety Loop Exterior
APLANKSThe Stretch Metal Hook-On Safety Loopsystem is designed for bigger surfaces
without concessions to accessibility.
The system executed in aluminium andwith exterior grade powder coating issuitable for use in exterior applications.
The locking plates prevent unauthorised
removal of the panels and at the sametime lock the panels in place to provide
wind load resistance.

WIND LOADS AND ENVIRONMENT*The wind load on an exterior ceilingdepends on factors like:- location of the building- surrounding environment- height- situation on the building- type of ceiling.
In addition, there may be other factorsthat influence the performance like(industrial) pollution, salinity (coastalareas) or humidity (nearby
watery environments).

DEMOUNTABILITY AND ACCESS
Each panel is individually demountable
by unscrewing the locking plate withan hexagonal Allen key through the
15 mm joint between the panels.
Once the panels are free they can beeasily lifted from the hook-on profile.

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.

Material
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 are
ISO 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.

HunterDouglas ® Ceilings - Stretch MetalMesh Types Tiles & Planks
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 2MESH TYPESStandardThe 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
