PRODUCTS OF OUR USED SAWN TIMBER – RECYCLE – USES :-
BELIAN
Family Luaraceae
Scientific Names
Eusideroxylon Zwageri
Source
Southeast Asia
Wood Appearance
Belian heartwood is
light to light yellow when freshly cut and darkens on exposure to light to a
deep red brown similar to kwila. Grain is straight and texture is moderately
fine to fine, and even. Belian is very durable.
Working Properties
In spite of its high density the wood can be sawn
without difficulty, blunting of cutters is only moderate, machines cleanly.
Difficult to glue with the synthetic resins.
Mechanical Properties:
Hard, heavy, strong and very dense timber
Uses
Heavy construction, bridge and wharf construction,
railway sleepers and decking.
Grading:
Select and better.
Heavy construction, marine construction,
boat construction, wharf construction, fence posts, heavy duty industrial
flooring, fender supports, telegraphic and power transmission posts and cross
arms, mallets, shingles, columns (heavy duty) and other works where high
strength and durability are required
SELANGAN BATU (Shorea sp.)provided by our company is an average hardwood, which is easy to
use and carve wood pieces. The normal color of Selangan Batu Logs can be yellow
brown and also have fine texture with wavy and interlocked grain.
Heavy
construction work, particularly when exposed to wet conditions and in contact
with the ground. Bridges, railway sleepers, power line poles, flooring,
etc,.
Heavy Construction, marine
construction, piling, beams, columns (heavy duty), posts, joists, rafters,
power line poles, mallets, fender supports, railway sleepers, vehicle bodies
(framework and floor boards), plywood (structural purposes), joinery, cabinet
making, heavy traffic flooring, cooling tower (structural member), heavy duty
furniture, laboratory benches, door and window frames, staircase (carriages,
newels and stringer), pallets (heavy and permanent type), tool handles (heavy

ALAN BATU
Family
Dipterocarpaceae
Other Names
Alan Bunga, Alan
Meraka, Alan Paya, Selangan Merah, Meraka, Red Selangan
*Alan Batu is the commercial name of heavy Shorea albida. Alan Bunga is the
commercial name of lighter Shorea albida.
Scientific Names
Shorea albida
Source
Southeast Asia
Wood Appearance
The wood is red brown
with clearly demarcated sapwood. Possible brittleheart and sometimes presence
of white streaks (resin canals). The grain is straight or interlocked and the
texture is medium. Density at 12 % moisture content: 0.80 g/cm3.
Working Properties
The blunting effect
is fairly high and peeling and slicing is not recommended or without interest.
Nailing is good but pre-boring is necessary. Risk of splitting in nailing.
Gluing is correct. Resin may clog the tools and may have a blunting effect.
Filling is recommended to obtain a good finish. Drying rate is normal and thin
stocks must be dried with care to prevent distortions.
Durability
Alan Batu is
moderately durable to fungi and it is durable to dry wood borers; sapwood
demarcated (risk limited to sapwood).
Uses
This exclusive species is
used for several purposes:
• interior: e.g. flooring, furniture, panelling and joinery , industrial or
heavy flooring
• exterior: e.g. flooring, ship building, joinery, panelling, vehicle or
container flooring
KERUING
Family
Dipterocarpaceae
Other Names
Gurjun, Dau,
Keroeing, Mai Nhang, Mai sat, Keruing bajak, Keruing beras, Kanyin, Yang,
Apitong, Hora
Scientific Names
Dipterocarpus spp.
Source
Southeast Asia
Wood Appearance
The heartwood is
light red to red brown or purplish red brown. Presence of resin. Possible wind
shakes. It has clearly demarcated sapwood. The grain is straight or interlocked
and the texture is coarse. Density at 12 % moisture content: 0.79 g/cm3.
Working Properties
The blunting effect
is high; peeling is reported to be good and slicing is not recommended or
without interest. Variable silica content. Some species are very resinous and
tend to clog tools. Occasional tearing on quartersawn. Nailing is good but
pre-boring is necessary. Gluing is correct but must be done with care due to
the presence of resin. It dries slowly. Moisture content is very variable
especially for the most resinous species. Careful stacking and end coating are
recommended.
Durability
Keruing is moderately
durable to fungi and is durable to dry wood borers; sapwood demarcated (risk
limited to sapwood). Several species are regrouped under the name Keruing of
the genus Dipterocarpus and the natural durability is variable from one species
to another. It is thus recommended to restrict the use without preservative
treatment for end-uses under biological hazard class 2.
Uses
Keruing can be used for several applications:
• interior: e.g. flooring, stairs, panelling, veneer, boxes and crates,
joinery
• exterior: e.g. exterior joinery, panelling, ship building, bridges, wood
frame house, vehicle or container flooring, heavy carpentry
Plywood for light woods. Resin and shakes may restrict end-uses. In Asia, this
species is used for sleepers and poles with a treatment.

kayatan, Kapur singkel, Kapur sintuk, Kapur tanduk, Petanang, Borneo
camphorwood, Paigie, Swamp kapur, Kapur kejatan, Keladan
Scientific Names

Source
Southeast Asia
Wood Appearance
The wood varies from
red brown to pink brown. Camphor smell. Presence of thin resin veins. It has
clearly demarcated sapwood. The grain is straight or interlocked and the texture
is medium. Density at 12 % moisture content: 0.74 g/cm3.
Working Properties
The blunting effect
is normal to fairly high; peeling is reported to be good and slicing is not
recommended or without interest. Nailing is good but pre-boring is necessary.
Gluing is correct. Possible oxidation in contact with iron. Resin exudation
sometimes troublesome in gluing. It dries slowly. Possible resin exudation
during kiln drying.
Durability
Kapur is very durable
to durable to fungi and is durable to dry wood borers; sapwood demarcated (risk
limited to sapwood).
Uses
Kapur can be used for several applications:
• interior: e.g. furniture, veneer, flooring, stairs, boxes and crates,
formwork, joinery, tool handles
• exterior: e.g. wood frame house, paneling, bridges, heavy carpentry,
joinery, vehicle or container flooring
