Circular hollow sections are used as columns and braces in portal frames structures. An example is a 114.3 x 5 CHS, which has a diameter of 114.3 mm and the wall is 5 mm thick.
Similarly to RHS and SHS sections, hot rolled CHSs are made at the mill as one piece, whereas cold formed CHSs are made of a flat sheet rolled at a radius and welded.
It is theirfore easy to note the difference, as the cold rolled CHSs has a weld all along its length.
ASTM A179 steel tube covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. A179 Cold drawn steel pipe shall be made by the seamless process and shall be cold drawn.
A179 black steel pipe minimum carbon content is 0.06%. The seamless steel tube minimum tensile strength of 325MPa, yield strength of 180MPa.The minimum elongation of A179 seamless pipe is 20%.

Galvanized steel coils are steel coils that have been coated with a layer of zinc to protect the steel from corrosion This process is known as galvanization These coils are widely used in various industries including construction automotive and manufacturing due to their durability resistance to rust and versatility The zinc coating provides a protective barrier that helps prevent corrosion and increases the lifespan of the steel
HS Code
The Harmonized System HS code for galvanized steel coils typically falls under the following classification
HS Code 7210 Flatrolled products of iron or nonalloy steel galvanized or plated with zinc

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)
Why Choose Our Reinforcement Bars?
Our rebar is manufactured to meet international quality standards, ensuring superior strength, reliability, and performance. Whether for residential homes or large commercial projects, our reinforcement bars provide the structural support needed for safe, durable concrete work.
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.
