Pickled Carbon Steel Coils

Pickled Carbon Steel Coils exhibits stable and controllable performance, high shape precision, and cold formability approaching that of cold-rolled sheets. Compared to cold-rolled sheets, costs can be reduced by 20%-30%, eliminating the on-site pickling process for hot-rolled sheets and reducing environmental and labor costs. China manufacturers utilize centralized pickling processes, which are more environmentally friendly, comply with green manufacturing standards, and are widely applicable in various fields such as automotive parts, appliance housings, construction machinery, and building steel structures.

China Factory Processing, Customization, and After-Sales Service System

2. Objection Handling:

24-hour response, case closed within 7 days, providing replacement/return/compensation solutions;

3. Technical Support:

One-on-one engineer service from the pickled carbon steel coil manufacturer, providing material selection, processing technology optimization, and coating scheme suggestions;

4. Logistics and Distribution:

Own fleet + third-party logistics, free delivery nationwide, overseas orders provide one-stop service for customs declaration, sea freight, and insurance;

5. Value-Added Services:

Material preparation according to customer's FORECAST, regular inventory warnings, and material performance training and application guidance;

6. After-Sales Commitment:

Free replacement for non-human-caused rust within 3 months for oiled products, unconditional return and exchange for dimensional deviations exceeding standards.

Case Study (Bangladesh National Grid Project)

Project Overview:

Product Specifications: 1200 tons of high-quality pickled carbon steel coils, SAE1006 material, thickness 1.2-2.0mm, width 1250mm

Technical Challenges: Yield strength ≤230MPa, precise control of oil coating amount, meeting the deep drawing requirements of compressor housings

Execution Highlights:

Narrow Composition Control: C≤0.08%, Mn 0.20-0.35%, S≤0.025%, P≤0.025%;

Process Optimization: Hot rolling coiling temperature controlled at 600-650℃, pickling speed 80-100m/min, ensuring surface quality;

Quality Control: 100% tensile testing per coil, yield strength deviation controlled within ±10MPa;

Delivery Cycle: Production completed within 15 days after order confirmation, customs clearance and loading completed within 7 days.

Project Results:

Helped the client increase annual production to 500,000 air conditioner outdoor units and 300,000 compressors, with a product qualification rate of 99.5%;

The client's production costs decreased by 25%, and delivery time was shortened by 10 days;
