When we think of wood, we usually think of its color, grain, or natural patterns. However, behind its appearance, each type of wood has its own class. This class is not just a label, but a determinant of how strong, durable, and suitable the wood is for various needs. Some woods can last for decades despite being exposed to rain and heat, while others are only suitable for decoration.
This system of classifying wood based on grade is key for those of you who want to make furniture, build structures, or simply beautify a room with wooden elements. By knowing the grade, you can more easily determine which wood is suitable, avoid making the wrong choice, and of course, achieve maximum results. So, are you curious about the different grades of wood and how they differ? Let’s discuss them one by one!
What is Wood Classification Based on Grade?
Wood classification based on grade is a classification system that groups wood according to its strength, durability against the environment, resistance to pests such as termites, and suitability for use (indoor/outdoor). Grades typically include grades I, II, III, IV, and V. The higher the grade, the stronger and more durable the wood generally is.
Characteristics of Each Class
| CLASS | Main Character | Suitable For |
|---|---|---|
| Class I | Wood is very strong, durable, resistant to termites and extreme weather | Main structures, pillars, outdoor flooring, luxury furniture |
| Class II | Slightly lower than Class I but still quite strong and durable | Lightweight outdoor furniture, frames, and structures that are not too heavy |
| Class III | Average durability and strength, may require extra care | Indoor furniture, wall panels, light applications |
| Class IV | Low strength and durability, more susceptible to damage when exposed to moisture/pests | Temporary ornamentation, suitable for casting and formwork |
| Class V | Very soft, lowest durability | Handicrafts, decorative items, short-term use |
Examples of Wood Based on Class
For clarity, here are some examples of wood types based on class:
- Class I: Teak (high grade), Ulin, high-quality Bengkirai.
- Class II: Merbau (medium quality), Sonokeling (less than prime), Acacia wood.
- Classes III-V: Wood such as Sengon, Albasia, Jabon is suitable for low classes.
Why is Classification Based on Class Important?
Knowing the class of wood is important so that you don’t make the wrong choice. If indoor decorations use class I wood, it will certainly be a waste of money. In fact, medium class wood is sufficient for light needs.
In addition, the class of wood also determines its durability. High-grade wood is usually more resistant to extreme weather and pest attacks, so your project can last longer without frequent maintenance. Plus, in terms of appearance, high-grade wood has more stable and attractive grains and colors, making the final result of the project look more elegant and classy.
Tips for Choosing Wood Based on Grade
To avoid confusion when determining the type of wood, here are some simple guidelines to follow:
- Identify its function, whether it is for heavy structures, decoration, outdoor or indoor use.
- Pay attention to specific gravity and durability. Wood with high specific gravity is usually strong.
- Make sure the wood has undergone the proper process, from proper drying to neat finishing.
- Don’t forget to check the grade and origin of the wood, because even if the type is the same, the quality of the wood can vary depending on its grade.
Now that you understand the classification of wood based on grade, choosing the right one for your needs is much easier, isn’t it? The point is, each type of wood has its own characteristics and uses, so don’t make the wrong choice. By knowing the grade, you can adjust your needs, whether for a strong structure, durable furniture, or simply decorations to beautify a room.
