Product Info

We cater to global power utilities, telecom operators, and EPC contractors by strictly adhering to international raw material standards:

StandardSteel Grade Key Applications & Advantages
ASTM A572Grade 50 / Grade 65Ideal for high-load transmission lines and tall monopoles with high wind resistance requirements.
EN 10025S355J2 / S275JRStandard structural steel grade for European utility projects, offering excellent toughness and weldability.
GB/T 1591Q355B / Q420B / Q460 High-strength structural steel providing exceptional cost-efficiency without compromising load capacity. 
JIS G3106SM490A / SM490BPremium 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.
