Long Steel Products…indispensable elements for Construction projectsAll Steel Products are classified into two major types, long products which are made of steel billets, and flat products which are made of steel slabs.In the Steel world, long products terminology refers to a wide range of steel products, that have long shapes includes beams, bars, and tubes. These products are also called structural elements since it plays a key role in any construction or architecture project as supportive and strong infrastructure.
What are Long products made of?Long products are made of steel “Blooms” or “Billets”,which are semi-finished products produced by the continuous casting of steel in order to reduce the cross-sectional area of steel ingots. Hot rolling is applied after that on steel to give it various shapes and qualities.This process eliminates the defects of casting and achieves a good quality surface to produce prime steel products and second-choice steel products.
Applications of Long Steel Products:The majority of long products are used in the construction industry.Beams and Bars are used as reinforcements in structures in buildings and towers.The wide range of long product applications include:
- Hardware manufacturing
- Machine industry
- Automotive industry
- oil, gas, and mining sectors.
- Bridges building
- Windows and door frames
- Metal furniture (tables, beds, etc.)
We can say that long steel products in all their forms are irreplaceable products enter in all aspects of our life.
Types of long products:
1. Beams and channelsAlso known as structural steel and used primarily in buildings and civil engineering.The cross-section of beams and channels consists of a middle wide part and two flanges at the top and bottom of the middle part.
- Channels: the two flanges in channels are in the same direction and It is distinguished between two basic forms:
- C-Channels: where the flanges are parallel and have inside right angles give it the shape of the letter “U”.
- U-Channels: where the flanges are tempered and have inside obtuse angles give it the shape of the capital letter “C”.
- Beams: consist of two horizontal planes, connected by a vertical component.
This means that the two flanges in beams are in two directions vertically to the wide part and it is distinguished between two forms:
- I-Beams: look like the capital letter “I” and the height of the middle part is greater than the width of its flange. I-Beams have better tensile-resistant and bearing of direct pressure.
- H-Beams: look like the capital letter “H” and has wider flanges than I-beams, then it is heavier and stronger than I-beams. H-beams have better mechanical properties per unit weight, which can save a lot of material and construction time.
2. Merchant BarsUsed by steel fabricators to produce a number of different products.They are mainly used in applications that require welding, punching and forming.Merchant bars offer a wide variety of multi-use products includes:
- Equal Angles: consist of two flanges that have the same length come together at a right angle of 90 degrees.
- These bars used in many structural projects like Power transmission and telecommunication towers.
- Unequal Angles: resemble the equal bars but the flanges have different lengths and used generally in the mechanical industry.
- Flat Bars or Rectangular Bars: a solid block of steel with a rectangular sectional-area that has variable lengths of height and width.
- Flat bars have many applications like frame and agricultural industry.
- Square Bars: a solid block of steel with a square sectional-area that has variable side lengths.
- These bars are used in road and railway building and many other industries.
- Round Bars: a solid block of steel with a circular sectional-area that has a variable diameter.
- These bars are used in the machinery and equipment industry, and in metal structures like bridges.
- IPE Bars: a type of I beams that designed according to the European Standard Universal Beam Profile with a straight internal surface of the flanges, that is the flanges are parallel.
- IPN Bars: a type of I beams that designed according to the European Standard Universal Beam Profile with an inclined internal surface of the flanges.
3. Welded Tubes
- a. Square Welded Tubes: have the shape of a long hollow square, and come in different sizes and wall thicknesses. Square tubes are frequently used in the automotive, solar, appliance, and agriculture industries and for sure in construction and towers building.
- b. Rectangular Welded Tubes: have the shape of a long hollow rectangle and come in different lengths of sides and different wall thicknesses. Rectangular tubes are used in the transportation and construction industries as well as in many other types of machinery.
- c. Rounded Welded Tubes: have the shape of a long hollow circle, and come in different diameters and wall thicknesses. Rounded tubes are used in constructions and buildings and also in trailers and structural fabrications.
