Round Flat Rebars

What is Round Flat Rebars?

Also called shaftround flat rebars, hot rollingIt is produced and offered for sale.hot rollingafter the procedurecold moldsbecome a rod by pulling fromis brought. In this way, it gains its durable and long-lasting state. Its durable chemical structures, corrosion resistance and smooth surface make it suitable for use in construction and industrial areas. Especiallyconcrete structuresIt provides a strong grip inside and a suitable working environment for other installations. These products, which are mostly in the concrete structure, preserve their form and chemical structure for many years without the need for maintenance and repair. In this way, it ensures that concrete structures, where people spend a great deal of time in their daily life, cultural, business and educational life, become stronger, balanced and durable.

All sizes of iron produced are extremely resistant to tensile breaking. coup andcorrosionThese products, which have extremely high resistance, become preferred with their shrinkage and expansion properties.

Usage Areas

foundation beam, column, beamWhile forming reinforced concrete elements such as slab, curtain and raft, concrete compressive stressesrebarmeets the tensile stresses.rebars tensile strengthsNotches are made on the edges to increase it. made this waynotched irons ribbed rebaris called. In our countryrebar 8 to 60 mmbetween diameter and12 m boyavailable on the market. Iron traders generally2000 -2500in kg.

round flat rebarIt has high strength, it is used in high important reinforced concrete structures with its welding and folding properties. Ribbed rebar is definitely used in structures that require special design such as skyscrapers, dams, subways and highways. Due to its low price and high strength contributions, ribbed rebar is one of the largest components of structures.
