Everything you need to know about the properties and cracks of bamboo sticks and bamboo poles.
Bamboo is a beautiful, versatile, and sustainable natural product that's increasingly being used for fences, garden projects, decorative elements, and even structures. But because bamboo is a natural material, it has unique properties that can influence its use. A common question from customers is why bamboo poles and canes sometimes crack. In this blog post, we explain all about the properties of bamboo, why cracks occur, and why this isn't a cause for concern.
Bamboo: A unique natural product
No two bamboo poles or sticks are identical. This is because bamboo grows naturally and therefore exhibits natural variations in color, thickness, and shape. This is precisely what makes bamboo so authentic and unique. When using bamboo poles in a project, you may encounter slight color variations or variations in diameter, but this actually contributes to the natural look.
Thickness and color differences in bamboo poles
Bamboo poles are naturally thicker at the base than at the top. The stated size is always measured at the thickest end of the pole, so slight variations in dimensions may occur. Bamboo poles may also discolor slightly over time due to exposure to weather conditions. This is a normal process that enhances the charm of bamboo.
Why do bamboo poles and bamboo sticks crack?
A common characteristic of bamboo is the formation of vertical cracks. This occurs especially during hot and dry periods. The reason for this lies in bamboo's structure: the material contains moisture, and when the moisture content decreases rapidly due to heat and dryness, the outer surface shrinks faster than the inner surface. This tension difference leads to cracks.
Does a crack affect the strength of bamboo?
No, cracks in bamboo don't affect the structural strength or durability of the post. Even with larger cracks, bamboo remains strong and usable. During wet and colder periods, the cracks may narrow, but they won't disappear completely. This natural process is a characteristic of bamboo that you should consider when using it in your garden or construction.
Bamboo and fences: Cracks in bamboo mats and rolls
Bamboo fence posts and bamboo mats can also crack. This is completely normal and a natural characteristic of the material. Although the cracks are initially noticeable, they gradually become more normal over time and do not negatively impact the lifespan or strength of the bamboo fence.
Bamboo remains a living natural product
Because bamboo is a natural material, it continues to behave as such. Small variations in color, thickness, and texture give bamboo its unique appearance. This means no two bamboo structures will be exactly the same – and that's precisely the beauty of this sustainable material.
Conclusion
Bamboo canes and poles are a strong, durable, and environmentally friendly material with unique properties. While cracks, color variations, and thickness variations may occur, these do not affect the quality or strength of the material. By understanding why bamboo cracks and how to manage them, you can maximize the benefits of bamboo's natural beauty and versatility in your garden or building projects!
