Laminated bamboo, also known as engineered bamboo, is a process where thin layers of bamboo are bonded together to create a stronger and more durable material. Here’s an overview of the typical steps involved in manufacturing laminated bamboo
Bamboo Selection
High-quality bamboo poles are selected for the process. The species chosen may vary depending on the intended application and desired properties of the final product.
Harvesting and Preparation:
Mature bamboo poles are harvested, typically between 3 to 5 years of age, when they have reached their maximum strength and density. The poles are then cleaned, stripped of their outer skin and nodes, and cut into desired lengths.
Boiling and Drying
To remove starches and sugars and prevent insect infestation, the bamboo strips are boiled in water or a chemical solution. After boiling, the strips are dried to reduce moisture content and stabilize the material.

Treatment and Conditioning
The dried bamboo strips may undergo additional treatment processes, such as heat treatment or preservative treatments, to improve durability, resistance to decay, and dimensional stability. Conditioning the bamboo to achieve a consistent moisture content is also important before the lamination process.
Lamination
The prepared bamboo strips are then glued together using an adhesive. The strips are typically arranged parallel to each other using our patented fingerjoint to maximize strength and stability. The adhesive is applied evenly between the strips, and pressure is applied to bond them together.
About the glue
The ideal situation would be to have an adhesive that is as environmentally friendly as the contribution our bamboo provides. Unfortunately, our suppliers are not yet able to manufacture an adhesive that is 100% environmentally friendly and meets our requirements. However, they are making progress in product development in this area. In the meantime, we strive to use an adhesive that complies with all the regulations set by reputable institutions. It's good to know that the adhesive used accounts for only a small percentage of the final product, so any potential environmental impact is minimal.
Pressing and Curing:
The glued bamboo strips are placed in a hydraulic or mechanical press, where pressure and heat are applied. This helps to ensure proper bonding and create a solid material. The curing process allows the adhesive to fully harden and bond the layers of bamboo together.
Finishing
After the lamination process, the laminated bamboo panels or beams are trimmed to the desired dimensions and sanded to achieve a smooth surface. Additional treatments, such as applying coatings or sealants, may be done to enhance the appearance and protect the material from moisture or UV damage.

The advantages of laminated Bamboo for versatile applications
The resulting laminated bamboo product exhibits improved strength, stability, and resistance to warping compared to solid bamboo. It can be used for various applications, including flooring, furniture, structural elements, and more.
It’s worth noting that the specific manufacturing process may vary depending on the manufacturer and the intended use of the laminated bamboo.
