In addition to domestic production, the demand for structural steel is very high , comprising of domestic production and imports 2005-2010.
Structural steel is a steel made construction material, profile formed with specific shape and cross section. Structural steel is the backbone of multi-story structures. They are used in construction for bridges, industrial sheds, structures, buildings and transmission line towers etc. The product range includes open sections such as channels, beams, LTZs and angles and closed hollow sections such as LTZ profiles, circular, rectangular and square hollow sections.
Hollow structural steels (HSS) are high strength longitudinally welded or bolted structural elements with circular or Rectangular/square cross sections. HSS has high strength-to weight ratios, excellent compression support characteristics and excellent torsional resistance. The I-beam is abeamwith anI- or H-shapedcross-section.The horizontal elements of the "I" areflanges which resist most of the bending moment experienced by the beam, while the vertical element known as theweb resists shear forces.
Market study
Rectangular hollow section (RHS) , Square hollow section (SHS) AND Circular hollow section s( CHS) are one of the most important construction materials for the development of construction, industrial and agricultural facilities in Ethiopia.
According to the information obtained from Ethiopian investment agency, a total of 16 companies had obtained permits in the production of steel profiles and other products. Out of the companies only five companies are in the operation phase currently.
On the other hand most of the remaining licensed companies are under pre investment stages. From the past experience and trend evaluation of previously licensed companies by the Ethiopian investment agency, it is very doubtful that all the licensed projects will be realized and become operational
In addition to domestic production, the demand for hollow section products is mainly met through import. Ethiopia imports a variety of hollow section products from the world market. All the products had been imported from five countries mainly from Asia, Europe, and Middle East.
The apparent consumption data of rectangular hollow section (RHS), Square hollow section (SHS) and Circular hollow section (CHS), Comprising of domestic production and imports (2005- 2010) is shown below.
