Our Main Products
Carbon Steel
01
Square Hollow Tubes
Carbon steel square tube is used for most general purpose applications. Relatively good mechanical properties with low carbon content and high quality weldability make it a common choice in manufacturing and structural applications. Easy to drill, weld and bolt.
02
Round Hollow Tubes/ Pipes
Al-Jadee offers a wide variety of carbon steel welded pipes / tubes specifications and sizes ranges for your specific application based on the fabrication method in which the steel will be used. The properties of carbon steel are high hardness and strength.
03
Rectangular Hollow Tubes
Rectangular Tube is made and formed from a coil and ran through a series of welding from its inside to form a (rectangular) shape. When it comes to its angles, its box-shape structure is used for better strength and rigidity of construction, railings, or truck frame projects. In measuring a rectangular tube, you need to measure its outside dimensions as well as its wall thickness.
Applications
These Steel Products are widely used in petroleum, chemical, pharmaceutical, food, energy, power, electronics, construction engineering and other industries. These Square & Rectangular are specifically made to add strength to a project while also concealing pipes, wires, and other types of moving parts. These two are both lightweight compared to other type of steel products since they are formed, welded, punched, and drilled already before being available to the market.
These are the applications that utilize both rectangular and square tubings:
Frequently Asked Questions
What is Carbon Steel ERW Pipe?
Electric Resistance Weld (ERW) Carbon Steel Pipe is manufactured by cold forming carbon steel into pipe. The pipe is formed by rolling carbon steel plate and then welding the seam with an electric current.
How is a welded tube made?
A welded tube is made from a flat steel strip, usually slit from a coil. This strip is pushed through a series of rollers, bending the strip into a round tube shape. Finally the ends of the strip are welded together, often by ERW technology (Electric Resistance Welding). This is a form of pressure welding which utilizes heat generated by electrical resistance of the material. No extra welding material is added. Welded pipes are cut to fix lengths, usually 6 or 12 m.
What is the difference between hot and cold formed hollow sections?
The different production methods of hot and cold formed hollow sections cause different product properties. They cannot simply be exchanged. The main differences are:
- Cold formed hollow sections have a larger corner radius, causing lower static values. Also, more welding material is needed when welding them together.
- Due to the cold forming procedure, the stress values in the corner areas are higher compared to hot formed hollow sections. This means a lower buckling curve according to Eurocode should be applied.
- For the same application, when welding in the corners is required, you need a higher steel grade of cold formed hollow sections compared to hot formed hollow sections.
How is a square or rectangular hollow section made?
Square and rectangular hollow sections can be made in two different ways. Either by using a flat steel strip that is shaped into its square or rectangular form by a number of rolling processes, and finally welded together. There is no heating of the steel involved, therefore these hollow sections are referred to as “cold formed”.
The other way is by starting with a round tube, shaping it into a square or rectangular shape by rolling. This often requires heating of the tube (there are exceptions) so they are referred to as “hot formed”. The round tube that is used as pre-material often is seamless, but it can also be a welded tube.
