Abstract:
Finger joint (FJ) is sustainable, eco-friendly and economically valuable concept for furniture industry. It
ensures the sustainable utilization of small wood cut pieces which removed as waste. Wood pieces are
jointed together using glued box comb finger joint cut It is a new concept for Sri Lankan Therefore, it is
necessary to analyze the physical properties, economic parameters and customer satisfaction to ensure
the sustainable utilization of timber through FJ production. This study attempted to compare the physical
properties such as strength, appearance and economic variables such as prices, cost of production and
profit and, customers' perception on FJ products. Comparison of FJ product (Model: STC B-FJ 0019) with
the similar size normal timber products (Model: STC B- 132) was done to achieve the objective of the
study. Strength reduction for FJ products was significantly high. Strength also varied with timber species.
Timber cost for FJ product was low because of small cut pieces but finishing material, labour, machinery &
factory overheads costs were higher than common furniture. Therefore, FJ furniture significantly
increased the profitability of FJ than common furniture. Customers' awareness on FJ products was much
lower but satisfaction about FJ was very high. When purchasing FJ products, customers gave more priority
for price and attractiveness. The uniqueness of and high demand for FJ products can increase market price
of FJ products and income of producers. Therefore, FJ product can be prompted to ensure sustainable
utilization of timber.
