Flat Steel Profile

 

Flat steel bar is one of the firmest and most durable irons produced in the recent times. Generally, it is the main carrier and the foundation stone in the parts it is used, especially in steel constructions.

 

The flat steel bar, spread in many areas, is thicker in comparison with the other irons. This increases its cost and labor. It is less preferred than the other iron types. This is because its areas of usage are more limited.

 

One of the main purposes of this product, used in steel constructions and automotive constructions, is to strengthen the supports of the structures and to strengthen the connection between the two profiles or between the floor and the ceiling.

 

In the production of flat steel bars, some standards are followed. These standards are applied worldwide and they are informant about the quality of the iron.

Flat Steel Bars are produced in accordance with the certificates of DIN

17000 ST 37.2/ASTM A36 ASTM A529-GR 50 FE 3608/S235 JR (EN 10025) S275 JR R (EN 10025).

Square Profile

 

The steel industry is a sector that has constantly renewed and developed itself until it has gained its current volume. The developing technology has rapidly increased the needs and has pushed the companies to produce a new generation of steel.

 

There is always an area of usage for every kind manufactured. Years ago, the constructors were working to provide a different functionality for a profile that was produced; now, with the current technology readymade irons, fitting all point with their functionality are produced.

 

Square Steel is one of the products produced in this way. These types of steel, ready for use as moulded in constructions and other areas of application, are less labored and less expensive in terms of production. Square steel can be produced in different sizes and thicknesses according to the needs. The produced products’ lenghts can be between 6-12 m and their thickness can be between 10 mm to 40 mm.

Ribbed Rebar

 

Ribbed Rebar is a kind of steel that increases resistance. It has dents on it, so that it better bonds with the concrete. It is manufactured in different countries in different standards. It has renewed itself as the expectations became higher by the day.

 

Carbon and Manganese are present in Ribbed Rebar. With the controlled cooling using water, the quality of Ribbed Rebar is increased. The carbon ratio should not be higher than 25%. If the carbon ratio is higher than this, the probability of breaks increases in Ribbed Rebar. It is generally manufactured as 12m in length. Ribbed Rebar is used in the building of prefabricated buildings, automotive industry, ship hull building and a structural component of the buildings.

 

What are the differences between Ribbed Rebar and Round Profile?

 

While Round Profile is good to keep the building erect, Ribbed Rebar enforces it. Thanks to its stripes and dents, it absorbs the concrete and prevents it from slipping. It is more durable compared with Round Profile. The only disadvantage it has is that because it does not let the lumping of the concrete, it can disintegrate the concrete. Saving time and having more elasticity is among the advantages of Round Profile. Today, Ribbed Rebar is preferred in constructions. The reason for this is that it makes the columns and beams more durable against earthquakes.

Striped Flat Steel Profile

 

Striped Flat Steel Profile is a specially manufactured Flat Steel Profile. It is used in buildings that Flat Steel Profile cannot be used due to the shape of its surface (e.g. bridge and viaduct abutments).

 

Thanks to the dents on it, it increases the resistance in constructions and makes the buildings more durable.

 

The dents on it offer functionality in the similar principle as Ribbed Rebar
