Product Description

Overview of International Cold-Rolled Steel Coils/Sheets Products

Core Definition: Cold-rolled steel sheets/coils are products made by rolling and hardening hot-rolled steel coils at room temperature after pickling to remove the scale. Their core features include excellent surface quality, precise dimensional tolerances, and superior mechanical properties.
Main Characteristics:

Surface Quality: The surface is smooth and clean, available in various finishes such as matte and bright. It is an ideal base material for subsequent processes like painting and electroplating.

Dimensional Accuracy: It has excellent thickness uniformity, an extremely narrow tolerance range, and superior flatness of the sheet shape.

Mechanical Properties: It has higher strength, hardness, and certain work hardening capacity. Its soft state (for deep drawing) or high-strength state can be controlled through annealing.

Midwest Steel Supply Services

Ultra - thin and High Precision

Ultra - thin Limit

Guigang cold - rolled steel strip coils can achieve a thickness of only 0.05mm, with the tolerance controlled within ±0.01mm, meeting the precision requirements of micro - sensors and other devices.

Surface Treatment Technology

We offer mirror - like or matte surface treatments with a roughness of Ra ≤ 0.1μm, which are suitable for optical devices and high - end decorative materials.

High - strength and thinning synergy

With a tensile strength of 270 - 800MPa, even when thinned by 30%, the same rigidity can be maintained, thus meeting the strength requirements while reducing energy consumption.

Nanometer - level slitting precision

Steel strips with a width ranging from 10mm to 1500mm can be slit with nanometer - level precision. Burrs are controlled to be ≤ 0.01mm, making it suitable for micro - electronic precision stamping.

Environmental Protection and Sustainability

Application of Environment - friendly Processes

Chromium - free passivation and water - based oiling technologies are adopted to ensure that products comply with RoHS/REACH environmental protection standards.

Zero - waste Intelligent Manufacturing System

Through AI - optimized production scheduling, the material utilization rate can reach up to 99.2%, reducing waste generation during the production process.

Green Supply Chain Management

Implement green procurement and logistics strategies to reduce the environmental impact of the entire supply chain and support sustainable development.

Our Service Advantages

Nanometer - level Slitting Technology

Steel strips with widths ranging from 5mm to 1500mm can be slit with nanometer - level precision. Burrs are controlled within 0.03mm, meeting the requirements of micro - electronic precision stamping.

Online Matching of Material Database

Guigang provides an online material database, which can quickly match the required material parameters and optimize customers' process routes.

One - stop Forming Service

We offer one - stop forming solutions including laser cutting, high - speed stamping, and continuous roll forming. The precision can reach up to ±0.1mm.。
