Is bamboo stronger than steel
Short answer: The claim is based on tensile strength relative to weight, where bamboo does remarkably well. As a building material, however, bamboo cannot simply replace steel, and the strength of the culm says nothing about the strength of a garment.
What the claim is based on
The comparison is about tensile strength relative to weight, not absolute strength. Bamboo is light, and the fibres in the culm wall can take a large pull along their length. If you work out strength per kilo of material, bamboo does well. That is where the claim comes from.
Why it is not the whole picture
Steel is uniform and predictable. Bamboo varies with species, age and moisture, and two culms from the same plant can behave differently. Bamboo is also stronger lengthwise than across, and it can split. Steel handles pressure, bending and pulling in a way that is easy to calculate.
In practice
Bamboo is used as a load bearing material and for scaffolding in parts of Asia, but on different principles from steel. Joints, lashings and the shape of the structure are adapted to the material. It takes experience to build with, and it needs treatment to last. See bamboo as a building material.
Not relevant for textiles
The strength of a bamboo culm says nothing about the strength of a piece of bamboo viscose. When the cellulose is dissolved and spun again, the structure of the plant disappears completely. The finished fibre is soft and smooth, with its own properties. See is bamboo hard wearing for how the fabric holds up.
The fibre in clothing
Bamboo viscose is a regenerated cellulose fibre. It is chosen for clothing for its softness and drape, not for its strength. The fabric is more fragile when wet and should be washed gently. More about the fibre in what is bamboo viscose.
Myths
There are several persistent claims about bamboo, and some of them mix up the plant and the finished fabric. It is worth asking whether a claim is about the culm or the fabric. The answer is often different. See more examples in bamboo myths.
What you can take from it
The claim is interesting as a fact about the plant, but it says nothing about how long a t-shirt will last. Yarn, knit, weight and washing decide that. If you want to know what to expect from your clothes every day, read how hard wearing bamboo fabric is in practice.
How to make clothes last
Wash at a low temperature with a mild detergent, and avoid the tumble dryer. Turn clothes inside out, and wash them with similar items so they do not rub against zips and buttons. Let them dry hanging. These are the steps that do most for the life of the fabric.

If you want to see what the fibre becomes, take a look at the textiles in the shop. For women, there are basics, nightwear and underwear made to sit close to the skin every day. Choose by fit and use. See the range in bamboo clothing for women.
In short
Bamboo is a strong plant for its weight, and that is interesting. But the strength belongs to the culm and not to the fabric. When you choose clothing, softness, fit and care are what matter, not how strong the plant is.
Frequently asked questions
Is bamboo stronger than steel?
In tensile strength relative to weight, bamboo does well. In absolute strength and uniformity it cannot replace steel, and it varies with species, age and moisture.
Does that make bamboo clothing extra strong?
No. When the cellulose is dissolved and spun again, the structure of the plant disappears. The fabric is chosen for softness and should be washed gently to last.
Is bamboo used in building?
Yes, as a load bearing material and for scaffolding in parts of Asia. It is built on different principles from steel, and the culms must be treated to last.
