ERW tubes, or Electric Resistance Welded tubes, are a type of steel tubing produced through a high-frequency welding process. These tubes are widely used in various industries due to their strength, durability, and cost-effectiveness. The manufacturing process involves passing a steel strip through a series of rollers, where it is formed into a cylindrical shape, and then welded longitudinally using electric resistance. This welding process ensures that the tube has a strong, uniform seam, making it suitable for a wide range of applications.
Key Features:
Material Composition: ERW tubes are typically made from mild steel, stainless steel, or galvanized steel, offering various grades to meet different strength and corrosion resistance requirements.
Manufacturing Process: The process of electric resistance welding uses heat generated by electrical resistance to bond the edges of the steel strip, creating a continuous tube. This process results in a smooth, clean weld seam that is often stronger than the base material itself.
Variety of Sizes: ERW tubes are available in a wide range of diameters and wall thicknesses. They can be customized to meet the specific requirements of industries like automotive, construction, and oil & gas.
Surface Finish: ERW tubes come with various surface finishes, such as mill finish, galvanized, or powder-coated, providing options for aesthetic appeal and enhanced corrosion resistance.
Strength and Durability: The ERW process ensures uniformity in strength and structural integrity, making the tubes ideal for high-pressure applications. The welded seam is highly resistant to cracking and fatigue.
Cost-Effectiveness: Compared to other types of welded or seamless tubes, ERW tubes are more affordable due to the efficient manufacturing process.
Applications:
Automotive Industry: Used in exhaust systems, chassis, and structural components.
Construction: Employed in structural frameworks, scaffolding, and fencing.
Oil & Gas: Ideal for pipelines, drill pipes, and other high-pressure applications.
Furniture Manufacturing: Used in the production of furniture frames and other industrial products.
Mechanical Engineering: Applied in various mechanical and hydraulic systems.
Benefits:
Precision and Consistency: The ERW process ensures that each tube is uniform in size and quality, minimizing defects.
Flexibility: Customization options for length, diameter, and wall thickness to suit specific needs.
Environmental Benefits: ERW tubes are recyclable, contributing to sustainability efforts in manufacturing.
Conclusion:
ERW tubes are a versatile and reliable choice for a variety of applications across different industries. Their high strength, cost-effectiveness, and customization options make them an excellent solution for projects requiring durable and high-quality steel tubing.
Reinforcement bars, or rebar, are crucial in the construction industry, providing strength and durability to concrete structures. Concrete is strong in compression but weak in tension, and rebar enhances its tensile strength. This ensures the longevity and stability of buildings, bridges, roads, and other infrastructure.
Key Features:
High Strength and Durability: Made from high-quality steel, rebar is designed to withstand heavy stresses and loads, preventing cracks and structural failure over time.
Corrosion Resistance: Some rebar is coated with anti-corrosion materials, protecting it from rust, moisture, and harsh environments, thus prolonging the concrete structureâ??s lifespan.
Variety of Sizes and Grades: Available in various diameters, lengths, and grades, rebar provides flexibility for diverse construction projects. Common grades include Grade 40, Grade 60, and higher, suitable for both residential and industrial applications.
Bendable and Malleable: Rebar can be bent and shaped to meet specific design requirements without compromising strength, making it ideal for complex architectural designs.
Easy to Install: Standardized lengths and diameters make rebar easy to transport, handle, and install. It can be welded, tied, or mechanically spliced for construction needs.
Cost-Effective: Rebar is a long-term solution for reinforcing concrete, ensuring structural integrity while minimizing the need for frequent repairs or replacements.
Applications:
Residential and Commercial Buildings: Used in foundations, columns, beams, and slabs to provide support and prevent cracking.
Bridges and Overpasses: Rebar ensures the safety and stability of high-stress structures.
Roadways and Pavements: Strengthens roads, sidewalks, and other paved surfaces, allowing them to withstand heavy traffic loads.
Industrial Structures: Reinforces heavy-duty industrial buildings, including factories, warehouses, and power plants.
Specifications:
Material: High-quality steel (carbon or alloy steel)
Length: Available in standard lengths or custom-cut for specific projects
Diameter: Ranges from 6 mm to 40 mm
Grade: Available in various grades, including Grade 40, Grade 60, and higher
Finish: Can be plain or deformed (with ridges for better bonding with concrete)

The material is loose steel scrap processed through an incinerating plant for domestic waste followed by magnetic separation, fragmentized into pieces and consisting partly of tin coated steel cans.
At a visual inspection, the material is fragmentized, with iron and steel parts, resulting partly cut or in shredded form.
The stock appears heterogeneous and contains all kind of cut or dismantled steel parts such as sheets, bars, frames, wires, bolts and other iron/steel household residues.
The incinerated scrap is eventually oxidized, due to the thermal and cooling treatments, that the material has been submitted to. The burnt scrap also contains minor slag parts, ash and iron oxide, due to the recovery process.
Such components are inherent and adhere to the scrap surface. The total impurities, can be sorted, but not fully removed.
The consignment does not contain any type of arms, ammunition, mines, shells, cartridges, radioactive contaminated, or any other explosive material in any form either used or otherwise.
The collected stock, is stored in open air, on cemented flooring.
Due to the scrap dimensions and the material conditions, this particular scrap, should be carefully evaluated first, by the end users, to confirm its adequate recovery ratio and its suitability to be re-melted in the electric arc furnace.

The Tire derived Steel or Tire Wire Scrap is a light melting scrap obtained during the shredding and granulation process of used tires.
Generally 10% - 20% of the weight of an old passenger car tyre usually consists of steel. An average shredding plant produces about 100-200 MT of steel tyre wire and its quality can vary according to technology, storing and management systems adopted by the producing plants.
We can provide tire wire scrap that still contains up to 20% rubber/fiber. This percentage is detected by manual separation test.
The material can be loaded loose in 40 HC container.

COR-TEN/CORTEN STEELS
Weather resistant structural steel. The anticorrosive properties of weather resistant steel are better than those of other structural steels in many applications. The steel is self-protecting: the rust layer on the surface becomes a tight oxide layer that slows down the progress of corrosion. The steel is an economical, long-lasting and fully recyclable material.
TYPICAL APPLICATIONS: The steel is used for various types of welded, bolted and riveted constructions e.g. steel frame structures, building cladding, metal sculptures (Angel of the North), agricultural vans, railway wagons, chimneys, bridges, water pipes, fans, boilers, tanks and containers, exhaust systems, vehicles and equipment constructions.
