What steel do you use for the crane structure?

<p>Our crane structures use high-strength Q235B and Q355B steel, sourced from certified Chinese mills, ensuring compliance with GB/T 700 and GB/T 1591 standards. For metallurgical cranes (YZ series), we apply heat-resistant and anti-spalling treatments to withstand high-temperature environments. All welding follows ISO 3834 procedures, and load-bearing components undergo 100% ultrasonic testing.</p><p>This material selection supports capacities from 0.5T to 150T across our 81 standard models, with certifications including CE and CCC. For specific project requirements, we can adjust steel grades to meet local standards (e.g., ASTM or EN).</p><p>Contact us on WhatsApp +86 19392777259 for a detailed material specification sheet tailored to your application.</p>
