Surface Treatment: Hot-dip galvanizing (80–120 µm coating thickness)
Tensile Strength: ≥ 490 MPa
Yield Strength: ≥ 345 MPa
Hardness: 130–160 HB
Working Temperature: -40°C to +50°C
Design Standard: GB/T 1591-2018
4. What key features make this HD23 Fixing Angle reliable?
100% OEM Compatibility: Custom-built to exact Zoomlion HD23 dimensions.
CNC Machining: Guarantees perfect alignment and tight pin/bolt fitting.
Pre-Drilled Holes: Ensures fast, accurate on-site installation.
Corrosion Resistance: Hot-dip galvanized finish withstands outdoor environmental wear.
5. How is quality assured during manufacturing?
Each batch undergoes strict quality control standards:
CMM Verification: Checks dimensional accuracy.
Magnetic Particle Inspection: Detects micro surface defects.
Certified Testing: Material composition report & load capacity certification.
System Compliance: ISO 9001:2015 certified production line.
6. Where is the HD23 Fixing Angle applied?
Zoomlion HD23 series tower crane mast connections
Tower crane erection, height extension, and maintenance
Construction equipment repair and component replacement
High-rise building and major infrastructure projects
7. How do I choose between OEM and aftermarket HD23 fixing angles?
Choose factory-direct fixing angles made to exact OEM specs with high-strength Q345B steel. Ensure the product includes hot-dip galvanizing, mill test reports (MTR), and ISO certifications to maintain original safety standards while reducing procurement costs.
