Plywood Grades

There are five main plywood grades. These grades describe the appearance and plywood strength. A lower grade can mean that the plywood does not resist punctures or hold nails very well. This can lead to an easier time cutting the plywood. The higher grades, however, are fairly strong. Each panel consists of various layers of veneer. Plywood is similar to chipboard, in that adhesives and pressure are used to form the board. Its strength can be increased if the veneers are placed opposite grained. This will not only cause it to be stronger over all, but also prevent cutting the plywood through if it is used as a work table.

The Five Main Grades

The grades run from A, which is the highest, to D. The reason there are five grades in total is because the C grade has two grades: C grade and C plugged grade.
The grades specify how many knots and patches and other imperfections the plywood can have. Most plywood is described by more than one grade.

Basic Rule: First Grade - First Side... Second Grade= Opposite Side

The first grade describes the face panel while the second describes the back panel (i.e. B-C grade means the front is B grade and the back is C grade).

Plywood Grades
A- Grade: Grade A is smooth. It can be painted and has a limited number of patches.

B- Grade: The B grade is solid, and has a few more knots and may even have very minor splits.
C- Grade: Grade C allows for limited splits and discoloration or sanding effects, provided the plywood strength is not affected. C plugged grade plywood is an improved version of C grade. The difference is that the splits and cracks are not as big as those found on C grade.
D- Grade:Grade D plywood features knotholes of up to three inches across the grain and even some cracks. This grade of plywood should never be used outdoors, as when it gets wet it will swell and break down.

Finply—A Grade Of Its Own

Finply is what manufacturers call Finnish plywood. It is generally more durable and attractive than regular plywood. While many plywood products are inexpensive, finply actually costs quite a bit. It can be combined with aluminum to make very modern looking furniture. Many woodworkers consider the high quality finply boards so special that it gets like a kind of grade on its own.

Jepara carving: the legend who became the pride of the island of Java

Jepara carving art is sculpture that has the range and patterns are very unusual. beauty and diversity of relief carving patterns that no one could have made memalihkan gaze when looking at the sculpture.  Jepara carving sculpture of a difference with other regions, but the most famous in Indonesia today is Jepara carving.

LEGEND

Narrated an expert on sculpture and painting named Prabangkara who live in the UB from the King of Majapahit kingdom, at one time the king sent Prabangkara to make king consort of painting as an expression of his love for the queen who was very beautiful and fascinating.

Wood Carving Center in Palembang Indonesia

The wood carving center in Palembang is located on Faqih Jalaluddin Street, near the Palembang Grand Mosque.  Dozens of showrooms, which are also used to give finishing touches to wood carvings, are available in this city center.  Palembang wood carvings, which are identified by dark red and golden colors, are displayed along this street.

You can also find unfinished products, those which have not been softened or painted.  Workers in each shop usually give their final touch before sale.

Gold is the most dominant color in Palembang carvings.  It distinguishes Palembang carvings from carving products from other parts of Indonesia, such as Jepara in Central Java.
Cupboards bodies, doors, or glass, as well as picture frames are usually painted in gold color.  Other parts are covered by dark red and black colors.  Pictures of flowers in black make these carvings more beautiful.

 

Bamboo Facts

Introducing you to the oldest, most remarkable resource on the planet. Both sustainable and plentiful, bamboo has been used for thousands of years to make a vast array of items. From housing and furniture to musical instruments and needles, its uses are endless.

Bamboo is strong, flexible and beautiful in both its natural and finished states. It is an abundant resource that could beneficially replace many of the less sustainable materials now commonly used in our daily lives.

Bamboo grows faster than any other plant on the planet, the record being an incredible 47.6 inches in a 24 hour period. It has been recorded at upto 180 feet tall with a diameter of over a foot and walls an inch or more thick. There are some fifteen hundred species that are native to every continent except Europe.

Bamboo is essentially a giant grass and as with your lawn, can be cut without killing the plant unlike other hardwoods such as teak and mahogany, where the whole tree dies when cut. What could be more environmentally friendly than a plant that can be harvested but just keeps on growing, with no forest destroyed in the process. It is the resource of the past, present and most definitely the future, and its popularity will only increase in time as more and more people realize its potential.

Timber Veneer

Timber veneer is from a natural and renewable resource competing with non-renewable commodities like steel,

aluminium and plastics. Its surface coverage is approximately forty times more than 25mm timber and

consequently is the most economical way of utilising precious wood.

Veneer is:

Produced by slicing or peeling selected logs. Sliced at approximately 0.6mm (this is normal thickness for the Australian market) or peeled at various thicknesses. Several methods are used to create various grain patterns. The most commonly produced patterns are as below. 

Crown or Flat Cut

 

Sliced veneer cut tangentially to the grain (i.e. parallel to the growth rings) is known as "crown cut" or "flat cut". It displays an attractive figure of bold sweeping ("cathedral") curves and ovals along the  centre of the leaf, with striped grain nearer the edges

 Quarter Cut

The timber is sliced at right angles to the growth rings and the result is a fairly straight line grain pattern.

Rotary Cut

Rotary veneer is normally produced in thickness from 0.9mm up to 3mm. The timber is peeled from the log in a continuous ribbon, against a blade in a lathe usually at high speed. The result is a bold, variegated or non-descript swirl grain pattern. Rotary veneer is predominantly used in plywood.
