ERW TUBE
Many industries rely on Electric Resistance Welded (ERW) tubes for their precision, strength, and versatility. These tubes are essential in construction, engineering, and manufacturing, providing durability and consistent performance across various applications.
At South West Steel Supplies, we offer high-quality ERW tubes designed to meet diverse project requirements. With a focus on reliability and precision, our tubes deliver superior performance, making them the ideal choice for professionals seeking long-lasting solutions.
What are ERW Tubes?
Electric Resistance Welded (ERW) tubes are produced by cold-forming flat steel plates into cylindrical forms and then longitudinal welding through electric resistance. Unlike extruded seamless tubes, ERW tubes use high-frequency electrical currents to join the edges, forming a solid and uniform weld.
The ERW process leaves the tubes with a smooth surface finish and an equal wall thickness, perfect for applications demanding accuracy and strength. Because of their dependability, affordability, and adaptability, ERW tubes are widely used in the construction, automotive, furniture manufacturing, and fluid transportation industries. Their high dimensional precision makes them perfectly compatible with other fittings and assemblies.
Key Specifications
Material Grades
Our ERW tubes are manufactured in a range of grades to suit various mechanical and structural applications, ensuring strength, durability, and precision for different industries.
ASTM A513 Type 1 (Hot Rolled)
Known for its high strength and resilience, this grade is commonly used in industrial frameworks, furniture manufacturing, and structural applications. Its durability makes it ideal for load-bearing structures and heavy-duty projects.
ASTM A513 Type 2 (Cold Rolled)
With a refined surface finish and tighter dimensional tolerances, this grade is perfect for applications requiring precision. It is widely used in automotive parts, decorative elements, and components where smoothness and accuracy are essential.
Dimensions & Common Applications
To meet a wide range of industrial and structural needs, we offer ERW tubes in various sizes and shapes, ensuring strength, durability, and precision for different applications. Our extensive selection provides solutions for industries such as construction, manufacturing, and automotive engineering.
Round Tubes
Commonly used in handrails, mechanical supports, automobile roll cages, and construction projects, round tubes offer excellent structural integrity and versatility. They are available in outer diameters (OD) ranging from 0.375″ to 16″, with wall thicknesses between 0.035″ and 0.250″, making them suitable for both light and heavy-duty applications.
Square Tubes
Widely used in gates, frameworks, and general structural applications, square tubes provide stability and strength. Their uniform shape makes them ideal for load-bearing structures, fencing, and fabrication projects. They are available in OD sizes from 0.500″ to 6″, with wall thicknesses between 0.049″ and 0.120″.
Rectangular Tubes
Designed for load-bearing structures, trailer frames, and equipment supports, rectangular tubes offer high strength and resistance to bending. Their elongated shape provides added stability in structural applications. These tubes come in OD sizes from 0.500″ to 8″, with wall thicknesses between 0.049″ and 0.120″.
No matter the scale or complexity of your project, our ERW tubes are designed to deliver long-lasting performance, ensuring you find the right fit for your specific requirements.
Why Use ERW Tubes?
Cost-Effectiveness
Their efficient manufacturing process saves material and production time making it a better and cheaper option for quality tubes. This is why ERW tubes are an economical choice for massive projects in construction, automotive, and infrastructure without compromising on durability and performance.
Precision and Uniformity
The electric resistance welding process guarantees close dimensional tolerances. This is why ERW tubes are the best for applications needing precision and consistency. Their smooth surface finish minimises extra machining, making them particularly suitable for aerospace, furniture production, and mechanical engineering industries.
Strength and Durability
Despite being cheap, ERW tubes maintain good mechanical strength and wear resistance. ERW tubes are a good option for load-bearing structures, pipelines, and heavy machinery because of their strength and resistance to wear under high stress and pressure.
Versatility
Their versatility makes them useful in many industries. If you look around, you’ll find them in scaffolds, fences, fluid conveyance systems, structural skeletons, and even car chassis. Their flexible size and shape make them perfect for more specific functions.
Eco-Friendly Manufacturing
Compared to other tube manufacturing methods, ERW tubes are more environmentally friendly because they use less energy and materials. Most ERW tubes are produced from recycled steel making industrial processes greener.
ERW tubes offer an extensive solution for varied applications by combining affordability, accuracy, strength, and sustainability.
