Tempinis

INTRODUCTION

The Standard Malaysian Name as well as the ASEAN Standard Name for the timber of Streblus elongatus (Moraceae). Vernacular name applied appears to be very uniform in that only tempinis is used throughout the country. Only one species attains tree size, viz. S. elongatus. The sapwood is light yellow-brown and is sharply differentiated from the heartwood, which is red-brown when fresh, darkening to a deep shade of brown or dark chocolate-brown on exposure.

Also known as Tempinis (Indonesia) and Khoi (Thailand).


DENSITY

The timber is very hard and very heavy with a density of 915-1,025 kg/m3 air dry.


NATURAL DURABILITY

The timber is very durable. Graveyard test carried out on the wood of S. elongatus gave an average service life of 11.3 years.


TEXTURE

Texture is fine and even with interlocked grain.


STRENGTH PROPERTIES

The timber falls into Strength Group A (Burgess, 1958).


MACHINING PROPERTIES

It is moderately easy to difficult to resaw and is slightly difficult to difficult to cross-cut. Planing is difficult but the planed surface is smooth.


NAILING PROPERTY

The nailing property is rated as very poor.


AIR DRYING

The timber seasons fairly rapidly with no defects at all. 13 mm thick boards take approximately 2.5 months to air dry, while 38 mm thick boards take 3.5 months.


SHRINKAGE

Shrinkage is very low, with radial shrinkage averaging 0.8% and tangential shrinkage averaging 1%.


USES

The timber is suitable for all forms of heavy construction like bridges, wharves, etc. Other uses include flooring (heavy traffic), railway sleepers, power transmission poles, beams, joists, rafters, columns (light to heavy duty), tool handles (impact), staircase (carriage, newel, riser, stringer, tread, bullnose, round end and winder), door and window frames and sills.
