Our Story

Zhangzhou Changtai Shiyuan Metal Products Co., Ltd. (Kingston) is a premier manufacturer rooted in the Gangyuan Industrial Zone, Fujian, China. With nearly two decades of expertise, we have evolved from a traditional workshop into a global powerhouse in metal craftsmanship.

A Legacy of Evolution:
Since 2006, we began our journey exporting wrought iron products, building a solid foundation in international trade. In 2013, anticipating the market's need for durability, we strategically transitioned to Aluminum Systems—lighter, rust-proof, and maintenance-free. By 2015, we expanded our portfolio to include high-end Aluminum Entry Doors, integrating security, aesthetics, and smart technology for luxury villas and commercial projects worldwide.

Today, we combine 20 years of export experience with advanced manufacturing to deliver factory-direct precision. We are not just making doors; we are crafting the face of your home.

Our Vision
"To leverage two decades of metalworking mastery, providing global clients with rust-proof, high-performance aluminum solutions that stand the test of time."
