Product Range

D Shaped Steel Pipe

Designed with one flat side for easy mounting, welding, and assembly. Commonly used in furniture frames, machinery, handrails, and structural applications. Available in standard sizes or customized to your project requirements.

Triangular Steel Pipe

Features a strong triangular profile that provides excellent rigidity while reducing weight. Ideal for solar mounting systems, equipment frames, steel structures, and architectural projects.

Welded Special Shaped Steel Pipe

Manufactured using high-frequency welding for stable dimensions and reliable strength. Suitable for industrial equipment, machinery manufacturing, automotive components, and structural applications.

Galvanized Special Shaped Pipe

Available with galvanized finishes for enhanced corrosion resistance in outdoor environments. Widely used in solar mounting systems, greenhouses, fencing, and construction projects.

Custom Shaped Tubes

Produced according to customer drawings, CAD files, or samples. Various shapes, materials, dimensions, and processing services are available to meet specific OEM and industrial requirements.

Our Customization Workflow

Consultation & Review: Send us your technical drawings (PDF/CAD/STEP files) or physical samples. Our engineering team reviews the geometry, wall thickness distribution, structural requirements, and annual volume to determine feasibility.

Engineering Assessment & Feasibility Report: We conduct a thorough structural and manufacturing analysis, selecting the optimal material grade (e.g., Q195, Q235, Q345, or Stainless Steel) and calculating roll-forming or welding parameters to prevent distortion or stress concentration.

Tooling Design & Sample Development: We design and machine custom roller dies in-house, execute trial production runs, and perform strict dimensional inspections to verify form, fit, and function before sending physical samples for your final sign-off.

Mass Production, Precision Processing & Export Packaging: Upon sample approval, we launch high-efficiency full-scale manufacturing, perform in-line secondary processing (such as CNC laser cutting, punching, or bending), and apply export-grade waterproof and anti-rust packaging to ensure damage-free global delivery.

Frequently Asked Questions

Q: What is the typical Minimum Order Quantity (MOQ) for custom profile development?

A: The standard MOQ is 3 metric tons per size, though smaller trial batches can be negotiated for initial sample runs.

Q: What is the standard lead time for mass production and global shipping?

A: Production typically takes 15 to 25 days, depending on order volume and secondary processing requirements.

Q: What export packaging methods do you use to prevent transit damage?

A: Tubes are securely bundled with steel strips, wrapped in waterproof plastic film, and loaded into heavy-duty containers or wooden crates.

Q: Can you provide Mill Test Certificates (MTC) with each shipment?

A: Yes, EN 10204 3.1 mill test certificates detailing chemical composition and mechanical properties are provided prior to dispatch.

Q: Do you charge tooling or mold fees for brand-new custom cross-sections?

A: Tooling fees apply for custom roller development, but costs are frequently refunded or credited back once cumulative bulk order volumes are met.

Q: What international quality standards do your manufacturing processes comply with?

A: Our operations comply strictly with ISO 9001 quality management systems and relevant ASTM, EN, or GB steel tube standards.

Q: Which payment terms do you accept for international trade orders?

A: We accept T/T (Telegraphic Transfer with 30% deposit and 70% against Bill of Lading copy) and irrevocable Letter of Credit at sight.

Q: Are third-party inspections (e.g., SGS, BV) accepted before shipment?

A: Yes, we fully welcome and cooperate with third-party inspectors appointed by international buyers to audit goods prior to loading.

Q: Can you apply specific laser-printed markings or logos along the pipe length?

A: Yes, custom ink-jet or laser branding displaying your company name, batch number, or standard specification can be applied upon request.

Q: How do you handle dimensional tolerance control during cold-forming?

A: Our inline laser measuring systems and experienced technicians maintain strict length and cross-sectional tolerances within plus or minus 0.1 mm.
