Tianjin KunRay International Trading Co., Ltd. is a professional supplier focusing on industrial nails, staples, and pneumatic gun nails, including coil nails, flooring nails, and various customized types widely used in construction, furniture, and packaging industries.

KunRay operates under BOST (Tianjin) Machinery Equipment Co., Ltd., serving as its dedicated global sales branch.
Although BOST was officially founded in 2019, our industrial foundation dates back over 20 years to our factory operations in Guangzhou, where we built one of the most advanced nail-making production lines in China at that time.
With decades of practical experience in nail production and machinery, we have gained a deep understanding of the fastener industry and its evolving technology.

In recent years, BOST Group has upgraded from equipment manufacturing to a more comprehensive industrial model, expanding its expertise to include high-quality nail products, especially new-generation L-shaped nails, while continuing to develop nail-making machines, wire drawing lines, and automatic nail packaging systems.
This enables us to offer customers complete, integrated solutions—from production to packaging.

Located in Tianjin, a key industrial and port city in northern China, we benefit from efficient logistics and high-quality raw materials, ensuring stable product quality and timely delivery.

With modern facilities, experienced engineers, and a strict quality control system, our products meet international standards and are widely exported to Europe, North America, and Southeast Asia.

We also provide OEM and ODM services to support our partners’ brand development.

At KunRay, we believe that trust and professionalism build lasting partnerships.
