Womic Steel is a professional manufacturer of S275JR EN 10219 cold formed structural steel pipes. With advanced ERW production lines, in-house testing laboratories, full EN 10204 3.1 certification, and flexible processing services, we deliver reliable structural steel pipe solutions for global construction and engineering projects.
Professional Manufacturing of S275JR EN 10219 Steel Pipes: Built on Standards, Backed by Capability
As a dedicated manufacturer of structural steel pipes, Womic Steel supplies S275JR EN 10219 cold formed welded steel tubes with a clear focus on compliance, consistency, and supply reliability.
Our role goes far beyond trading finished pipes—we control the entire production chain, from raw material sourcing to forming, welding, inspection, processing, and export delivery.
Every S275JR EN 10219 steel pipe we deliver is produced to meet the structural performance requirements defined by EN standards, while also responding to real project needs such as dimensional accuracy, welding reliability, traceability, and delivery assurance.
Understanding EN 10219 and the Role of S275JR Steel Grade
EN 10219 is the European standard governing cold formed welded structural hollow sections manufactured without subsequent heat treatment. The standard focuses on geometric accuracy, weld integrity, and mechanical performance suitable for load-bearing structures.
Within this standard, S275JR represents a widely used non-alloy structural steel grade, offering a balanced combination of strength, toughness, and weldability. The “JR” designation confirms verified impact performance at room temperature, ensuring reliability for general structural applications.
At Womic Steel, S275JR EN 10219 steel pipes are produced specifically for projects where structural safety, fabrication efficiency, and cost control must coexist.
Manufacturing Process That Ensures Structural Reliability
Womic Steel manufactures S275JR EN 10219 pipes using advanced ERW (Electric Resistance Welding) production lines. High-quality hot-rolled steel coils are precisely slit, cold-formed into round, square, or rectangular profiles, and welded under tightly controlled parameters.
The cold forming process allows excellent dimensional consistency while maintaining the mechanical properties required by EN 10219. Continuous online monitoring ensures weld seam stability, while post-forming straightening and sizing guarantee accurate geometry, which is critical for steel structure assembly and on-site installation.
This process-driven manufacturing approach is what transforms a standard specification into a dependable structural component.
Production Capacity and Supply Stability
Womic Steel operates multiple automated welded pipe production lines with a stable annual output capacity supporting large-scale and repeat orders. Common sizes of S275JR EN 10219 pipes are regularly produced, while non-standard dimensions can be arranged through flexible scheduling.
This manufacturing scale allows us to support both project-based bulk supply and small-quantity orders, with no minimum order quantity. Even single-piece orders are accepted, making us a practical partner for fabrication shops, contractors, and overseas distributors.
Quality Control Driven by In-House Laboratory Capability
Quality at Womic Steel is not dependent on external testing alone. Our in-house laboratories perform full verification of chemical composition, mechanical properties, and dimensional tolerances.
Testing includes tensile testing, yield strength verification, elongation assessment, dimensional inspection, and weld seam evaluation. Each production batch is documented and supplied with EN 10204 3.1 material certificates, ensuring full traceability from raw steel coil to finished structural pipe.
This systematic quality control ensures every S275JR EN 10219 steel pipe is compliant not only on paper, but in real structural performance.
Dimensions, Tolerances, and Structural Accuracy
S275JR EN 10219 pipes supplied by Womic Steel cover a wide dimensional range, including round, square, and rectangular hollow sections. Dimensional tolerances are strictly controlled according to EN 10219 requirements, with particular attention to outer dimensions, wall thickness consistency, straightness, and corner radii for hollow sections.
Accurate dimensions reduce fabrication adjustments, speed up installation, and directly lower total project costs—an often overlooked but critical advantage.
Processing, Packaging, and Project-Oriented Delivery
Beyond pipe production, Womic Steel provides value-added processing services such as fixed-length cutting, end preparation, beveling, hole drilling, surface cleaning, and corrosion protection treatments.
Packaging is designed according to transport mode and destination. Pipes are securely bundled, protected against moisture and corrosion, clearly marked for identification, and prepared for container or bulk shipment. This approach minimizes handling damage and ensures smooth customs clearance and site delivery.
Our logistics coordination experience allows us to align production schedules with shipping windows, reducing lead time risks for overseas projects.
Application Fields of S275JR EN 10219 Steel Pipes
S275JR EN 10219 steel pipes supplied by Womic Steel are widely used in steel structures, industrial buildings, warehouses, bridges, machinery frames, equipment supports, and general construction projects where reliable load-bearing performance is required.
Their combination of structural strength, weldability, and dimensional accuracy makes them a preferred choice for both engineered structures and standardized building systems.
