Detailed Specification of Cold Rolled Steel Coil
Executive Standard: GB/T 11253-2019, GB/T 5213-2019; European Standard EN 10130, Japanese Standard JIS G3141Production Base: Liaocheng, Shandong (in stock warehouse); Direct shipment from Tianjin Port & Qingdao Port, delivery within 5-7 working daysPackaging: Standard moisture-proof and rust-proof packaging with reinforced coil core, complete with Mill Test Certificate
1. Product Overview
Cold rolled steel coil is manufactured by taking hot rolled steel coil as raw material, removing oxide scale via pickling, then continuous rolling at room temperature below recrystallization temperature. It can be further processed by annealing and temper leveling. Featuring smooth surface, precise dimension and stable mechanical property, it is a fundamental industrial metal material.Core features: Free of oxide scale, low surface roughness, tight dimensional tolerance, excellent stamping and bending performance.Product status: Hard rolled coil (non-annealed), soft annealed coil (mainstream), temper leveled coil.
2. Production Process
Hot rolled steel coil → Pickling → Cold continuous rolling → Annealing → Temper leveling → Slitting & recoiling → Inspection & packaging → Warehousing & delivery
