At Kaleliler, our state-of-the-art production facility is at the forefront of fastener manufacturing, specializing in the production of bolts, stud bolts, anchor bolts, nuts, and custom fasteners. Utilizing both hot forging and cold forming techniques, we work with a diverse range of steel and materials to meet the stringent demands of various industries. Our in-house heat treatment capabilities further ensure the durability and performance of our products.

Our production process is fully integrated, encompassing in-house electro-galvanizing and hot-dip galvanizing facilities. Additionally, we offer Geomet and Zn-Nickel coating solutions through our network of approved suppliers, providing comprehensive surface treatment options that meet the highest industry standards.

The hot forging process at Kaleliler is a key differentiator, particularly in the production of large-scale bolts and specialized fasteners. This method allows us to deliver superior strength and reliability, catering to the needs of critical applications. In our precision machining section, we produce custom components tailored to the unique requirements of diverse sectors.

Kaleliler’s production facility is equipped with an extensive range of advanced machinery and equipment, enabling us to achieve rapid and high-quality production. Our capabilities include an automatic cutting unit, hot forging unit, machining unit, thread rolling unit, heat treatment unit, surface treatment unit, and a fully equipped quality control laboratory.

Our product range is extensive, featuring KLR-marked bolts and screws with diameters ranging from M12 to M72 and lengths up to 900 mm, threaded rods and studs from M8 to M220, nuts from M20 to M72, anchorage bolts, and custom-bent items like U-Bolts and J-Bolts. Alongside our production capabilities, we maintain a comprehensive inventory of stock items to meet immediate needs across all fastener types.

Recent investments at Kaleliler have significantly enhanced our production capacity and quality standards. Notably, the commissioning of our fully automated hot-dip galvanizing facility, with a daily capacity of 40 tons, represents a major leap forward. This facility is fully managed by robotic systems, ensuring precision and consistency across all processes. The integration of environmentally friendly ultrasonic and mechanical surface treatment methods also minimizes the risk of hydrogen embrittlement, a critical concern in high-strength fasteners.

Further strengthening our capabilities, a new hot forging line has been commissioned, doubling our production capacity in this area. Equipped with an automatic feeding system and advanced robotics, this line ensures stable and controlled forging processes, enhancing both efficiency and product quality. Our commitment to digitalization is reflected in the integration of an automation system with our existing ERP infrastructure, facilitating more accurate data analysis and driving overall productivity.

In line with our continuous improvement philosophy, Kaleliler has also invested in cutting-edge quality control technologies, including a torque testing device capable of testing bolts up to M72—a first in our industry. These advancements reinforce our position as a trusted supplier, particularly in the steel construction and wind energy sectors, where reliability and precision are paramount.

Kaleliler remains dedicated to innovation and excellence, setting new benchmarks in fastener production through our comprehensive and technologically advanced manufacturing processes.
