Application of ERW Steel Pipe
Automotive industry - Essential for manufacturing exhaust systems and other critical components.
Infrastructure projects - Used for constructing bridges, scaffolding, and structural supports.
Oil and gas - Used for pipelines and drilling rigs due to high pressure.
Water and sewage systems - Pipes are used for conveying water and waste materials.
Agricultural applications - Utilized in irrigation systems and greenhouse structures.
Hvac systems - Utilized in the construction of ducts and ventilation systems.
General engineering - Perfect for various engineering applications needing precision.
Fencing and signage - Suitable for outdoor signage frames and security barriers.
Various forms of ERW Pipes
Rhs (rectangular hollow sections)
Rectangular hollow sections (rhs) are a popular choice for mechanical, structural, and construction applications. This is due to the flat surface resulting in a structural solution that is more economical for joining and various other types of fabrication work.
Shs (square hollow sections)
Square hollow sections (shs) are a popular structural steel tube. They combine the attributes and structural behaviour of rhs and chs. Shs features a flat surface that's also economical for joining and welding, with clean lines and minimal edge preparation required.
Chs (circular hollow sections)
Circular hollow sections (chs) were the first form of hollow section and are commonly used in a wide range of structural, mechanical, and construction areas. Chs are favoured for their uniform strength, smooth appearance, and versatility.

Main Materials Used in Erw Pipe Production

Steel: The first choice
Carbon steel: The most common raw material for erw pipe manufacturing is carbon steel. Known for its economic value, availability, and balanced strength and ductility, carbon steel pipes are used in a wide range of applications. They can be used for gas and water transportation, structural purposes, and even furniture manufacturing.
Alloy steel: Alloy steel is the first choice for applications that require higher strength, corrosion resistance, and heat resistance. Alloy steel pipes contain elements such as chromium, nickel, and molybdenum, making them an indispensable material in industries such as oil and gas, chemical processing, and power generation.
Beyond steel: Other materials
Stainless steel: Stainless steel stands out in situations where corrosion resistance and aesthetics are crucial. Its uses range from architectural design to the food processing industry.
Copper and aluminum: These materials are chosen because they have unique properties, such as electrical conductivity and ductility, which make them well suited for specific applications.

Services we offer
Water cutting
Water jet technology, also known as water jet and water cutting technology, is a real cold cutting. Speed jet water cutting.
Beveling
We can apply any type of bevel to any degree desired. Beveling can be applied to the surface of pipes of any size or diameter.
Threaded
Pipe thread is a thread located on the pipe wall for connection, mainly used for the sealing connection of water, gas, oil and other pipelines. We offer npt and bspt pipe threads.
