Moisture Content-- BS 1088 plywood must have a moisture content between 6% and 14% when it leaves the factory. Finishing -- Boards will be sanded on both sides equally. Length & Width -- The length or width of a board produced as a standard size shall not be less than the specified size nor more than 6.3 mm (0.25") greater than the specified size.
Plywood for flooring applications is often tongue and groove (T&G); This prevents one board from moving up or down relative to its neighbor, providing a solid-feeling floor when the joints do not lie over joists. T&G plywood is usually found in the 13-to-25-millimetre (1 ⁄ 2 to 1 in) range.
For thickness above 0.093” (2.4 mm) and up to 0.375” (9.5 mm), a discrete laminated sheet (similar in size (l x w) to plywood) was produced by the cutdown process. The cutdown sheets were racked and moved from vat to vat by overhead tracked cranes. Each vat was successively less concentrated until the desired 0.05% was reached.
Several units of measurement were historically used in Singapore to measure length, mass, and volume. During 1968–1970, the metric system was adopted in Singapore. [1] The metric system is used for most official purposes and only metric measures are permitted for trade. [2] Despite these restrictions, fabric is still commonly sold by the ...
This yields veneer that looks like sawn pieces of wood, cut across the growth rings; such veneer is referred to as "crown cut". A half-round lathe in which the log or piece of log can be turned and moved in such a way as to expose the most interesting parts of the grain, creating a more textured feel and appearance; such veneer is commonly ...
Typically they range in size from 30 by 48 inches (76 cm × 122 cm) to 36 by 60 inches (91 cm × 152 cm). They are, as one would expect, considerably heavier than the gypsum core type panels. Portland cement based panels are ideal for truly wet locations like shower surrounds and for locations where a Portland cement based thin-set material is ...
His business grew considerably following the 1973 oil crisis when he open his own plywood mill in Indonesia. [5] He diversified into palm oil in 1979. Since 1985, Tanoto’s companies have planted 30,000 acres of palm oil plantation each year, with plantations spread over three provinces in Sumatra with a total land area of 160,000 hectares. [ 5 ]
Laminate panels are used instead of plywood because of their resistance to impact, weather, moisture, shattering in cold (ductility), and chemicals. Laminate panel layers (called veneers) are glued together with adjacent plies having their grain at right angles to each other for greater strength.
