Indonesia Furniture Manufacturer Lumber Grade

Before purchasing wooden furniture straight from the manufacturer, the timber grade must be mentioned. Wooden furniture manufacturers all over the world, including Indonesia furniture manufacturers, must completely comprehend the grades of timber they employ in order to explain them to their clients and business partners. Lumber, also known as timber, is a sawed and prepared log of harvested trees used for a variety of purposes such as woodworking, construction, flooring, and furniture manufacture. Because the trees are growing organically, the properties of the generated timber vary greatly. This is why lumber grading is critical for quality assurance purposes.

There are several methods or criteria for determining lumber grades. This page will describe timber grades, specifically the grades for teak wood, which is the most frequent and best material used by Indonesian furniture manufacturers.

Explained: Wood Types and Lumber Grade

There are two types of wood: softwood and hardwood. Softwood refers to the wood of a coniferous or cone-bearing tree, whereas hardwood refers to the wood of broad-leaved trees. Hardwood is the most commonly utilized for furniture production because it is more durable and stronger than softwood owing to its higher density.

Meanwhile, the strength of hardwood timber varies depending on the tree; for example, teak wood is significantly stronger and more durable than sungkai wood. This explains why teak wood furniture is far more expensive than sungkai wood furniture, despite the fact that both will make excellent interior furniture if properly treated and finished.

Understanding timber grade is critical for both woodworkers and furniture producers, as well as their customers. Knowing the grade of the timber is critical for determining the quality of final furniture goods created from that material. Lumber grading is not subjective; you cannot select on your own criteria and rate the grade based on your personal preferences.

Several characteristics are commonly used to determine the grade of timber. These factors may include the harvested tree's species or type, surface and size measures, cuts, surface look, the portion of wood cut, and many more.

Purchasing Wooden Furniture from an Indonesian Manufacturer

Indonesia furniture producers often employ a variety of materials to create their furniture goods. They include solid woods like teak, mahogany, and sungkai wood, as well as bamboo, natural rattan, pandan rattan, and paper-cord rattan. Each of the aforementioned materials has unique specializations and traits that set it apart from the others. Even timber made from the same type of harvested tree (for example, teak wood) might vary in quality.

As a buyer or consumer, it is essential to understand the materials used by your Indonesia furniture manufacturer in order to ensure the quality of your acquired products. This covers the quality and treatments of each timber used in the creation of furniture. In order to gain greater durability, solid wood is usually kiln-dried. This procedure reduces the quantity of water in the wood, resulting in dry wood that is a great furniture material. This is especially important for wood or items destined for export.

Teak Wood Excellence and Teak Wood Lumber Grade Explained

Teak wood furniture is the finest option if you want furniture that will last for a long time. Teak wood is a sturdy wood with exceptional properties. It is sturdy, long-lasting, and termite- and weather-resistant. This is why teak wood furniture is frequently much more expensive than other types of furniture. But don't be concerned! If you buy teak wood furniture, you will wind up saving a lot more money since you can use it for years without having to go to great lengths to care for it.

Teak wood is a star in Indonesian furniture due to its superior quality. This wood is in high demand, but supply is restricted. It is because teak wood takes years to mature before it can be harvested. Because of the high concentration of natural oil in teak wood, its endurance is extraordinary. Natural finishing is best suited to this type of wood, not only because the oil content of teak wood does not work well with brilliant solid color finishing, but also because natural finishing will highlight its exquisite natural textures.

However, as previously said, it is extremely normal for teak wood to differ from one another. As a result, the costs of teak wood furniture vary greatly. Don't be fooled by the label that states the furniture is made of teak wood; the price may reflect the item's quality and the grade of the lumber used to make it. So you already see why it is critical for you to learn more about the lumber grade of teak wood.

In terms of lumber quality, teak wood has its own grading system that is shared and agreed upon by Indonesian furniture producers. Teak wood is typically classified into three primary classes, which are as follows:

Teak Wood of Grade A (The Best Quality)

This is the finest grade teakwood timber available. Grade A teak timber is sourced from the heartwood of mature trees, which is located in the middle of the log. Teak wood is deemed mature when it has grown for at least 20 years and the diameter of the log has reached 30cm or greater. Due to the largest quantity of natural protective oils in it, Grade A teak timber has a golden brown or dark brown hue, consistent and solid wood grains and fibers, and a glossy surface with few surface blemishes. It is also the most difficult area of the log, which is slightly greasy to the touch.

Because of the high oil content in Grade A teak timber, it is the most durable type of teak wood, with excellent resistance to termites and other insects, rot, and any adverse (or even extreme) weather conditions such as rain, sun, snow, and frost. Grade A teak timber accounts for just a fifth to a quarter of the total volume of a single tree. This, along with the exceptional characteristics of Grade A teak timber, makes Grade A teakwood not only the most costly, but also the finest for furniture manufacturing.

This variety of teak is planted, grown, and harvested directly by Perum Perhutani, an Indonesian state-owned corporation whose mission and power are tied to the administration and conservation of Indonesian forests. As a result, there is no reason to mistrust the quality of this lumber, because Perhutani has strict criteria for ready-to-harvest trees.

Teak Wood Grade B (Good to Standard Quality)

Grade B teak timber refers to the outer portion of the heartwood, which accounts for around 25-30% of the whole log. It is a lighter brown hue than the Grade A version, which has a deeper brown tone. It has irregular grains and fibers, and its density is lower than that of Grade A teak timber. In terms of natural oil content, Grade B has just traces of it, making it less lustrous and greasy to the touch. Furthermore, it is not as long-lasting as Grade A teak timber. Despite its ordinary grade, this sort of teak wood is nevertheless suitable for furniture construction, particularly for indoor furniture.

Teak Wood Grade C (Lowest Quality)

When compared to the other two grades of teak wood listed above, Grade C is the worst in quality. As a result, its pricing is also the lowest among all types of teak wood timber. Grade C teak lumber can come from juvenile trees or the sapwood, which is the outermost section of older trees. This section consumes around 40% of the total teak log. It is the softest section of the log, with a very irregular and less dense wood fiber that ranges in color from dazzling white to yellowish.

Although it is taken, sawed, and prepared from the same teak log, it lacks the natural oils found in the rest of the wood. As a result, Grade C teak timber is quite fragile; it is not as termite- and weather-resistant, and it is readily destroyed even when stored indoors. Even after being covered in protective finishing and oiled, the durability of Grade C teak lumber is less than that of the other two.

Teak wood lumber grading is mostly determined by the portion of the wood picked, as stated in the description of each grade. Furthermore, additional factors like as the lumber's provenance or origin, as well as its maturity, determine its grade. Even the heartwood of a 10-year-old Kampong Teak wood (which grows on property owned by village people) will remain in Grade C.

We now know that there are numerous types of timber and grades of lumber. The grade of lumber indicates its quality. This is reflected in the cost of the lumber's boards or goods. You may always select the greatest furniture for your needs based on your budget and preferences. Before purchasing your furniture, speak with a reputable Indonesia furniture maker about the grade of the lumber used in its creation to ensure that your money is properly spent.
