Hardness & Density + Why is it Strong?

Despite its natural hollowness, bamboo is surprisingly durable and dense, making it a valuable material for construction purposes in comparison to more traditional options.

Its impressive hardness is reflected on the Janka scale, which rates bamboo at 1,200 to 1,400, varying based on the age and species of the bamboo plant.

Bamboo Fibers

Bamboo consists of fibers that possess exceptional strength and high silica content. It can be made even stronger by treating it with a process called carbonization, which also makes it more resistant to bugs and water damage.

Carbonized bamboo is an exceptional choice for outdoor furniture and decks, surpassing other materials in terms of suitability and performance. 

Moreover, it can withstand the elements, including exposure to sunlight, rain, and temperature fluctuations, without warping, cracking, or deteriorating. 

Tensile Strength & Compressive Strength and Resistance

Bamboo is incredibly strong because of its long parallel fibers, which resist stretching, making it great for construction materials like scaffolding, bridges, and roofs.

How About Structural Beams and Panels?

Bamboo can also be used as a building material for structural beams and panels. The durability, lightweight, and strength of bamboo make it a suitable alternative to traditional and common building materials such as wood, steel, and concrete.

Bamboo has a higher strength-to-weight ratio than most other materials, and its natural resilience against bending and compression makes it ideal for structural applications.

However, proper engineering and design are necessary to ensure the bamboo has great structural integrity and withstands the required loads and stresses.

Bamboo Compared to Other Building Materials

Steel

This material can be compared to steel and can even replace steel as a building material because of how strong bamboo is.

In fact, the tensile strength of bamboo makes it even stronger than steel, which means how much it can resist being pulled apart. This is why some people tend to call bamboo “Green Steel.”

It is lighter, more flexible, and more fatigue-resistant than steel. Bamboo can withstand compression better than concrete and steel and has a protective outer layer that makes it resistant to moisture and rot.

The strength of bamboo does not lose when exposed to moisture and can even gain strength. Additionally, when processed properly, bamboo can become even stronger and more durable. So its often recommend bamboo for building things like houses or furniture.

Wood

The strength of bamboo is generally stronger than wood, but the strength can depend on the specific types of bamboo and wood being compared. 

bamboo compare to other wood

Bamboo is also more flexible than timber and can withstand many impacts, making it useful in construction, especially in windy and earthquake-prone regions. 

In contrast, the high tensile strength of most woods varies in different directions, and cutting and splitting affect their strength. Even the strongest and densest wood, such as maple, does not match bamboo’s strength.

Oak Wood

Oak wood and bamboo are both popular sustainable materials used in construction and manufacturing, but bamboo is generally stronger than Oak lumber.

Bamboo has significantly higher compressive strength and tensile strength compared to oak wood. The tensile strength of bamboo is particularly much higher than oak wood.

3.79 Mpa -20.9 Mpa

5.50 Mpa

Bamboo

19.96 Mpa – 23.80 Mpa

142 Mpa – 265 Mpa

Concrete

The tensile strength of bamboo is higher than concrete, which means it is better at withstanding forces that try to pull it apart. Many mixtures of concrete, however, are stronger in terms of compressive strength, meaning they can withstand forces that try to crush them.

The strength of bamboo comes from its fibrous structure, which allows it to bend and flex without breaking. Additionally, the natural glue-like substance in bamboo, called lignin, gives it added strength and durability.

However, concrete has advantages, such as its ability to withstand high compressive strength and forces and its durability in harsh weather conditions.

Titanium

While titanium products can be comparable to bamboo, products made of bamboo are ultimately stronger. Bamboo bicycle frames and chopsticks, for example, are stronger than their titanium counterparts due to the epoxy sealant and interlocking fibers.

But how strong is bamboo fiber [1] compared to the fibers of titanium?  When comparing the durability of titanium and bamboo fiber, bamboo fiber is the stronger option because titanium is homogeneous and lacks a structured arrangement of weaving metals or fibers. 

Additionally, bamboo provides flexibility and stiffness for riders.

Bone

Bamboo and bone can be compared by measuring their tensile and compression strength, but this can vary depending on the bamboo species or type of bone.

bamboo and bone

But generally, is bamboo stronger than bone? Bamboo has a higher yield strength of 142 Mpa compared to the 104-121 Mpa range of yield strength for limb bones. 

Comparing a strong bone to a bamboo cable, bamboo is generally stronger than cortical bone and significantly stronger than cancellous bone.

Iron

Is bamboo stronger than Iron? Bamboo is a construction material that is stronger and stiffer than many others, including iron. However, it is not a direct replacement for iron rods because iron has higher tensile strength.

Nevertheless, bamboo can serve as a substitute for iron rods in several applications, especially as reinforcement in concrete structures.

Bamboo has a high strength-to-weight ratio, making it easy to apply and cost-effective.
Manufacturers can use bamboo composite materials to create shapes and rods that perform as well as solid iron rods.

Drawbacks of Using Bamboo

Availability & Cost

I’ve explored the remarkable versatility of bamboo when it comes to crafting furniture and constructing various items. Nevertheless, sourcing bamboo may pose challenges, particularly in regions where it isn’t readily available.

Even though China and India grow a lot of it in big farms, it can still be expensive to buy. This is because lots of people want it. For budget options, you may want to check out the cheapest hardwoods for furniture.  

Limited Places of Growth

Another drawback is the limited growth places for bamboo. For bamboo to thrive, it requires particular circumstances, such as having deep, well-drained soil with a slightly acidic pH similar to the conditions found in tropical forests.

These conditions cannot be met everywhere, resulting in bamboo only being grown in mass in certain parts of the world.

Lack of Quality Control & Standardization

Lastly, there is a lack of standardization and quality control in the bamboo industry. Since bamboo is not regulated like other building materials, the quality of products made of bamboo can vary greatly.
