European EN 10204:2004 ensures channel traceability, mirroring GB/T 247 (Steel Products-Inspection Documents):
Certificate Types: EN 10204 Type 3.1B (most common for channels) includes:
Heat number (unique batch identifier, matching GB/T 247's "heat number").
Chemical composition (C, Mn, Si, P, S) and mechanical properties (yield/tensile strength, elongation, impact energy).
Dimensional inspection results (depth, flange width, web thickness).
Manufacturer accreditation (e.g., ISO 9001).
Marking Requirements: Each UPE/UPN channel is marked with heat number, grade (S355JR), size (UPE 200), and manufacturer ID-identical to GB/T 247's marking rules. This allows full traceability from raw material to final installation, critical for defect recalls.
Chinese Regulatory Compliance: EN 10204 Type 3.1B certificates are accepted by Chinese authorities (e.g., Ministry of Housing) as equivalent to GB/T 247 Level 2, simplifying import procedures for European channels.
EN 10204 ensures European channels meet GB's transparency standards, building confidence in quality and safety.
