Deep Drawing Quality DDQ Galvanized Coil Sheet 0.6mm Appliance Auto Forming Grade

Stamping a deep, complex panel without cracks demands steel that flows smoothly. The Deep Drawing Quality Galvanized Coil Sheet is produced with high elongation and a favorable r-value so the metal stretches evenly through deep draws, radii and tight corners.

Produced by Shandong Jingwei Steel Manufacturing Co., Ltd., this DDQ grade combines excellent formability with a galvanized surface, allowing appliance and automotive manufacturers to stamp parts and skip a separate corrosion-protection step. The result is fewer rejects, less tool wear and faster production.

• High Elongation 38% Minimum: Exceptional ductility lets the sheet stretch into deep, complex shapes without tearing or necking.
• Optimized r-value: A high plastic strain ratio improves drawing performance and reduces thinning in critical areas.
• Clean Forming Surface: A controlled surface and drawing oil reduce friction, galling and tool wear during press work.
• Built-in Corrosion Protection: The galvanized coating protects formed parts from rust without a separate coating line.
• Stable Gauge and Flatness: Consistent thickness and flatness keep press feeding accurate and repeatable.
• Fewer Defects: Uniform properties lower the risk of splits, orange peel and springback on demanding parts.
• Ready to Finish: The surface accepts painting, powder coating and assembly operations downstream.

DDQ galvanized coil is used wherever a part is drawn deeply. Typical products include washing machine drums and tubs, refrigerator liners, air-conditioner outer panels, sink bowls and heater components.

Automotive suppliers use it for inner panels, brackets, oil pans and structural reinforcements where forming severity is high. Metal furniture, shelving and lighting housings also rely on DDQ material for smooth, crack-free stampings with corrosion protection built in.

Coils are oiled for drawing, wrapped in plastic film and moisture-barrier paper, steel-strapped and shipped eye to sky or eye to wall. Protective film can be added for scratch-sensitive finishes.

All material is produced under an ISO 9001:2015 quality system with a mill test certificate covering mechanical and coating properties. Shandong Jingwei Steel Manufacturing Co., Ltd. offers trial coils and technical support to help customers dial in their stamping process.
