Our company was founded in 1977 in Sinop by our father, the late “Sami KAYA” and started its activities initially in the glass industry. Later, it transitioned to the PVC window and door systems manufacturing industry in 1992, by revamping itself. The knowledge, the experience and high standards we have gained throughout our commercial adventure has become our general policy, and with this mentality, our company started manufacturing PVC window and door accessories in 1997. Technological and human resources investments made in this field are its R&D, Molding Room, Aluminum Casting, Zamak Metal Injection, Plastic Injection, Press Shop, Anodized Coating, Electrostatic Powder Coating Lines, Chromating Facility and Zinc Coating Facility. KAYA-PEN Company continues its production as an environmentally friendly integrated facility with more than 400 employees with an indoor area of 20.000m2 closed area 56.000m2.
