Raw Material-The Manufacturing of Steel Tubular Poles
High-performance power transmission and telecom infrastructure require exceptional structural durability. At our manufacturing facility, every steel pole, steel tubular pole, steel monopole, and tubular steel tower is built using high-yield-strength hot-rolled steel plates and seamless/welded steel pipes.
Product Info
We cater to global power utilities, telecom operators, and EPC contractors by strictly adhering to international raw material standards:
| Standard | Steel Grade | Key Applications & Advantages |
| ASTM A572 | Grade 50 / Grade 65 | Ideal for high-load transmission lines and tall monopoles with high wind resistance requirements. |
| EN 10025 | S355J2 / S275JR | Standard structural steel grade for European utility projects, offering excellent toughness and weldability. |
| GB/T 1591 | Q355B / Q420B / Q460 | High-strength structural steel providing exceptional cost-efficiency without compromising load capacity. |
| JIS G3106 | SM490A / SM490B | Premium rolled steel engineered specifically for welded structural applications. |
Uncompromising Quality Control at Raw Material Stage
To ensure zero-defect manufacturing, our raw material inspection process covers:
1. Chemical & Mechanical Verification: Re-testing yield strength, tensile strength, and elongation against mill test reports.
2. Thickness & Dimension Tolerance Check: Ensuring precise plate thickness for stable CNC plasma cutting and bending.
3. Surface & Flaw Inspection:Ultrasonic non-destructive testing (NDT) to prevent hidden internal defects prior to pole forming.
