Based in the heart of Addis Ababa, Tariku Metals has built its reputation on a foundation of reliability and deep industry knowledge. We are your trusted local source for high-grade materials, including our specialized Carbon Steel Spring Bar Rod. Understanding the demanding requirements of Ethiopian industries, we provide a product engineered for resilience and consistent performance. Our commitment is to support your projects with quality materials that meet rigorous standards, ensuring your operations run smoothly and effectively from the ground up.
This particular carbon steel is formulated with a precise balance of elements to achieve its notable characteristics. The composition grants it an excellent tensile strength, allowing it to withstand significant pulling forces without deforming. It also possesses a high yield point and remarkable elasticity, meaning it can be bent or stretched and will reliably return to its original shape. This combination of strength and flexibility is what makes it perfectly suited for applications where repeated stress and motion are a constant factor.

When selecting carbon steel spring bars, consider factors like the required strength, durability, and fatigue resistance for the specific application. Also, evaluate the environment's corrosion potential and the bar's ability to retain spring properties over time.
Carbon steel spring bars are generally not suitable for cryogenic applications due to their reduced toughness and brittleness at extremely low temperatures. Materials like stainless steel or special alloys are preferred for such conditions.
Carbon steel spring rods are available in various sizes, typically ranging from 1/4 inch to several inches in diameter, with lengths varying based on application requirements. Custom sizes can be manufactured to meet specific load, stress, or design needs.
You’ll find this spring bar rod is incredibly versatile, forming the backbone of many essential products. It’s commonly used to create durable springs for automotive suspensions, industrial machinery, and various agricultural equipment. Beyond springs, it’s also ideal for crafting clips, latches, and any component that requires a dependable ‘memory’ for its shape. From the tools that build our infrastructure to the vehicles that connect our communities, this material provides the unseen strength that ensures longevity and safety in countless applications.
