2. WOOD PRODUCTS IN ABE:
LUMBER
TIMBER
ENGINEERED WOOD PRODUCTS
Plywood
Oriented strand board
Fibreboard
Particle board
Laminated veneer & etc.

3. LUMBER
 Processed wood that has
been sawn or shaped into
uniform and useful size like
beams, planks, or boards.

4. TIMBER
Wood that has been
processed and prepared
for structural use, typically
larger in dimension than
lumber.

5. ENGINEERED WOOD PRODUCTS
 Engineered woods are generally made from the same hardwoods
and softwoods used to manufacture lumber, but mixed with
additives like adhesives. This type of wood often utilizes waste
wood from sawmills, and are treated through chemical or heat
processes to produce wood that meets size requirements that are
hard to find in nature.
 Ex:plywood, oriented strandboard,particle board, laminated
veneer, fireboard and etc.

11. Harvesting: Trees
are selected based on
species, size, and
quality.
Sustainable forestry
practices are often
employed to ensure a
healthy ecosystem.
Transportation: Harvested
logs are transported to a
sawmill.
 Sawing of Trunks:
trunks are cut and logs
are cut down into sizes

12. Transportation:
Harvested logs are
transported to a
sawmill.
Log Scaling: Logs are measured
and recorded for volume and
quality assessment.
 Debarking: Bark is removed
from the logs using mechanical
debarkers.
Sawing: Logs are cut into rough
planks or boards using various
sawing techniques. Common
methods include plain sawing,
quarter sawing, and rift sawing.
Edging and Trimming: Planks
are trimmed and edged to meet
desired dimensions and remove
defects.
Drying: Moisture is
removed from the lumber
through air-drying or kiln-
drying processes.

13.  Grading:Lumber is graded based on quality, appearance, and
structural characteristics.
 Planing: The surfaced lumber is planed to create a smooth,
uniform finish.
 Quality Control: Inspection for defects, knots, and other
imperfections.

15. ENGINEERED WOOD PRODUCTION PROCESS
 Log Preparation: Logs are peeled or sliced into thin veneer sheets.
 Veneer Drying: Veneer sheets are dried to the appropriate moisture
content.
 Gluing: Veneer sheets are glued together with adhesives, typically in
a cross-grain orientation.
 Pressing: The assembled veneer stack is pressed to form a strong
bond.
 Trimming and Sanding: Excess material is trimmed, and the surface
is sanded for a smooth finish.
 Quality Control: Plywood sheets are inspected for defects,
thickness, and overall quality.

16. ENGINEERED WOOD PRODUCTION PROCESS
 Grading: Grading is done based on appearance and structural
properties.
 Cutting: Plywood sheets are cut into standard sizes or customer-
specific dimensions.

18. Log Scaling: Logs are measured
and recorded for volume and
quality assessment.
 Debarking: Bark is removed
from the logs using mechanical
debarkers.
Sawing: Logs are cut into rough
planks or boards using various
sawing techniques. Common
methods include plain sawing,
quarter sawing, and rift sawing.
Edging and Trimming: Planks
are trimmed and edged to meet
desired dimensions and remove
defects.
