Our primary focus is on high-pressure gas cylinders, which face tough challenges in their lifespan. What sets us apart is our innovative approach. We've developed composite fully wrapped cylinders using high-strength, high-modulus carbon fibre materials, resulting in exceptional durability. Safety is paramount, and our unique "pre-leakage against explosion" mechanism significantly reduces the risk associated with cylinder failure compared to traditional steel cylinders. Plus, they're more than 50% lighter, making them a practical and efficient choice.

Zhejiang Kaibo can currently produce both Type3 and Type 4 cylinders. You might wonder about the difference between our Type 3 and Type 4 cylinders. Type 3 cylinders have an aluminium liner with a carbon fibre wrap, while Type 4 cylinders use a polymer liner with a carbon fibre wrap, making them even lighter. Our cutting-edge Carbon fibre Type 4 Cylinders, available in various capacities, excel in safety, with robust construction and flame-retardant design. They are over 30% lighter than Type 3 cylinders.
