ZAM Coated Round Steel Pipe

ZAM Coated Round Steel Pipe is manufactured from Zinc-Aluminum-Magnesium coated steel strip through ERW welding process. The Zn-Al-Mg alloy coating forms a stable protective layer, providing excellent corrosion resistance and longer service life.

Superior Corrosion Resistance: Zinc, aluminum, and magnesium form a dense protective layer, effectively isolating moisture, oxygen, and salt spray corrosion, thus improving the steel pipe's corrosion resistance.

Self-Healing Protection: The magnesium and aluminum elements in the ZAM coating promote the formation of a protective film, maintaining edge corrosion resistance even after cutting, punching, and other processing.

Excellent Processing Performance: The coating has strong adhesion, supporting cutting, welding, bending, stamping, and other processing methods to meet the needs of various structural component production and on-site construction.

Solar Mounting Systems: Used for outdoor structures such as ground-mounted photovoltaic brackets and tracking systems, meeting long-term weather resistance requirements.

Greenhouse Structures: Suitable for greenhouse frames in high-humidity environments, improving structural corrosion resistance.

Construction Structures: Used for steel structure frames, supports, and guardrail systems, balancing strength and corrosion resistance.

Infrastructure Projects: Used in road guardrails, municipal facilities, and public works projects.

Steel Coil Inspection: Inspects the chemical composition, mechanical properties, and surface quality of steel coils.

ERW Forming & Welding: Produces round steel pipes using ERW high-frequency welding technology, ensuring weld stability.

Sizing & Straightening: Controls outer diameter, wall thickness, and straightness to ensure dimensional accuracy.

Cutting & Inspection: Cuts steel to length according to order requirements, and performs dimensional, surface, and coating inspections.

Packing & Delivery: After quality confirmation, performs export packaging and shipping.

Raw Material Inspection: Confirms the steel grade, chemical composition, and mechanical properties to ensure material reliability. Weld Quality Inspection: Utilizes online and non-destructive testing to ensure consistent weld quality.

Coating Thickness Test: Inspects the weight and uniformity of the ZAM coating to ensure corrosion resistance.

Mechanical Testing: Tests tensile strength, yield strength, and elongation.

Quality Documents: Provides MTC material certificates and test reports, and supports third-party inspections by SGS/BV/Intertek.

Size Customization: Supports customization of outer diameter, wall thickness, length, and material grade.

Processing Service: Supports processing needs such as cutting, beveling, threading, and drilling.

OEM Packaging: Supports customer logos, specification markings, export packaging, and customized container loading solutions.
