Operating from the heart of Addis Ababa, Desta Steel has built a strong reputation for supplying essential components that drive progress across Ethiopia. Our carbon steel screws are a perfect example of this commitment, manufactured with precision to provide reliable, strong, and cost-effective fastening solutions for a huge range of projects. We understand that quality materials are the foundation of durable work, which is why our screws are trusted by professionals in construction, manufacturing, and maintenance to deliver consistent performance and unwavering strength.
The composition of our carbon steel screws is straightforward yet effective, primarily consisting of iron and carbon, which gives them their fundamental strength and durability. Through a controlled manufacturing process, we ensure these screws achieve excellent mechanical properties, including high tensile strength to resist pulling apart and good hardness to prevent bending or shearing under load. This reliable combination makes them tough enough to handle significant stress in various demanding environments.
