Product
Birch plywood (Riga Ply) overlaid with a phenol film on both
the sides. The wear side has a rough wire mesh pattern (W); the
reverse side normally is smooth (F), although it can have wire
mesh pattern, too (grade W/W). Riga Tex rough wire mesh
overlay withstands hard wear and it can be used for many different
floor-panelling purposes.
Film colour
Normally dark brown (120g/m2). Other standard colours are
light brown (120g/m2), dark brown (220g/m2), green
(120g/m2), black (120g/m2). Grey (174 g/m2)
and red (220 g/m2) colours on special order.
Applications
Vehicle floors, pedestrian bridges, storage and factory floors,
storage shelves, loading platforms, ship decks, pier surfaces. In general
- applications where high wear resistance and/or good anti-slip properties
are required.
Advantage
The wire mesh surface has high wear resistance and anti-slip
properties, surface is weather and waterproof, resists to commonly used
chemicals. Environmentally friendly.
Gluing classes
Plywood is glued with waterproof phenol formaldehyde resin adhesive.
Bonding is resistant to weather and boiling water. It meets requirements
of the following standards:
EN 314 / 3 rd class;
BS 1203 / H4 (previously WBP);
DIN 68705 Part 3 / type BFU 100.
Formaldehyde emission
In accordance with the standard EN 13986 formaldehyde
emission meets the Class E1 requirements. Test method EN 717
Part 2.
Overlaying
The panels are overlaid with a phenol film and have a wire mesh
pattern imprinted during hot pressing process. The reverse side overlaid
with a similar phenol film, and normally the reverse side is smooth. The
unit weight of Riga Tex plywood film is 120g/m2 or
220g/m2. On special request, panels can be overlaid with
multi-layer phenol film and both the sides can have a wire mesh pattern.
Wire mesh pattern can be of different kinds:
Large Mesh (grade
WL) - 2.5 mesh per 1cm;
Small Mesh (grade WS) - 4.5 mesh per 1cm.
Overlaying
characteristics
The overlaying surface is highly resistant to abrasive wear and it
does not crack. It is also resistant to weather and moisture as well as
commonly used chemicals. The wire mesh patterned surface provides high
anti-slip properties. Riga Tex panels can be machined by using
normal woodworking equipment. During machining extra hard cutting tools
are recommended.
Abrasion resistance according to the Taber test (EN 438-2):
depends on applied film, surface texture*, conditions of product storage
and application, thickness of film (see below) a.o.
Small mesh resistance to
wear parameters mesh ones.
It is possible to obtain overlaid plywood above 10 000 revolutions.

product.
Edges sealing
Edges of the panels are matched with the face against absorption of
moisture by using acrylic paint. Other colours are available and the edges
may be unsealed at customers' request.
