The weight of steel strips can vary widely depending on their dimensions (thickness, width, and length) and the type of steel used (e.g., carbon steel, stainless steel). Generally, the weight of steel strips is calculated based on their volume (area × thickness × density of steel). Here are approximate weight ranges for typical steel strips:

• Thin Steel Strips (0.1-1.5 mm thick): About 1.2-18 kg/m²
• Medium Steel Strips (1.5-3 mm thick): About 18-36 kg/m²
• Thicker Steel Strips (3-6 mm thick): About 36-72 kg/m²

These weights are approximate and can vary based on specific dimensions and steel grade. For precise weight calculations, it’s essential to consider the exact dimensions and density of the specific steel material being used.

Steel strips are typically produced from coils of steel through a process that involves cutting and slitting the coil into strips. Here’s how steel strips are made from coils:

Coil Production:

Steel Melting: Raw materials such as iron ore and recycled scrap metal are melted in a furnace to produce molten steel.
Continuous Casting: The molten steel is cast into large slabs, which are then rolled into coils of various thicknesses and widths.

Coil Slitting:

Uncoiling: The steel coils are uncoiled, often using a decoiling machine, to feed into the slitting line.
Slitting: In the slitting line, the coil passes through rotary knives that slit it into strips of the desired width.
Recoiling: Each slit strip is then recoiled into individual coils or wound onto spools.

Surface Treatment:

Depending on the application, the steel strips may undergo surface treatments such as pickling (acid treatment) or coating (e.g., galvanization) to enhance corrosion resistance or improve surface finish.

Quality Control:

Throughout the slitting process, quality control measures ensure that the steel strips meet precise dimensional tolerances and surface quality standards.

Packaging and Distribution:

After inspection and quality assurance checks, the steel strips are packaged for shipment to customers or further processing facilities.

This coil slitting process enables metal manufacturers to efficiently produce steel strip in different widths and thicknesses to meet the needs of a variety of industrial applications such as automotive parts, building materials and packaging solutions.

1. Oscillate Winding Packaging

Applicable Materials: stainless steel strips, carbon steel metal strips, aluminum metal strips, etc.

Features: The metal strips are wound layer by layer by oscillating back and forth, and the winding is tighter, which reduces the coils’ slippage or displacement during transportation. This can effectively save space and improve transportation efficiency, especially suitable for long-distance transportation and export.

Advantages:

• Tighter winding, reducing space occupation.
• Improve coil stability and prevent edge damage.
• Applicable to strip materials that require long roll lengths.

2. Wooden Pallet Packaging

Applicable Materials: stainless steel strips, carbon steel strips, aluminum metal strips, etc.

Features: The steel strip rolls are placed on wooden pallets and wrapped with plastic film or cardboard for easy transportation and stacking. Wooden pallets provide basic physical support and are often used for standard transportation.

3. Steel Pallet Packaging

Applicable materials: heavier materials such as stainless steel strips, carbon steel strips, and aluminum metal strips.

Features: Steel pallets are stronger than wooden pallets and suitable for heavier or high-strength steel strips. They can provide better support and pressure resistance, suitable for heavy materials.

4. Plastic Film or Waterproof Film Packaging

Applicable Materials: all types of steel strips.

Features: The outer layer is wrapped with waterproof plastic film to prevent the steel strip from getting damp and contaminated during transportation and storage. Waterproof film is a common protective material, especially suitable for export transportation.

5. Cardboard or Plastic Edge Guard

Applicable Materials: stainless steel metal strips, carbon steel strips, aluminum metal strips, etc.

Features: Add cardboard or plastic edge guards to the edges of the steel strips to prevent the edges from being damaged during handling. Especially suitable for thin materials such as stainless steel and aluminum metal strip.

6. Metal Straps and Locks Fixed

Applicable Materials: all steel strip materials.

Features: Metal straps and locks fix the metal strips to the pallet or bracket to prevent loosening or displacement during transportation. This system is suitable for long-distance transportation or coils that require high stability.

7. Rust-Proof Packaging

Applicable Materials: carbon steel strips.

Features: Carbon steel is prone to rust, so anti-rust paper or anti-rust oil film is used during packaging to prevent the material from being oxidized during transportation or storage. Suitable for carbon steel materials that need to be stored for a long time.

The type of metal strip edge usually varies according to the production process, material properties, and application requirements, mainly including the following common edge types:

1. Mill Edge

Definition: Mill edge refers to the untreated edge of the steel strip, which comes directly from the hot rolling or cold rolling production line without any trimming.

Features:

• The edge is uneven and may have tiny burrs.
• The cost is low because the edge-trimming process is omitted.
• It is suitable for applications where edge accuracy is not required.

Applicable materials: carbon steel strip, stainless steel strip, aluminum metal strip, etc.

2. Slit Edge

Definition: Slit edge refers to the edge of the steel strip that has been sheared or trimmed, and the edge is relatively neat and smooth.

Features:

• The edge is precisely sheared and has no burrs.
• It is suitable for applications with high-edge quality requirements, such as products that need further processing during the manufacturing process.
• The edge shape is regular and the dimensional accuracy is high.

Applicable materials: all strip materials, especially stainless steel, and aluminum metal strips.

3. Round Edge

Definition: Round edge refers to the process of processing the edge of a metal strip into a smooth rounded shape.

Features:

• The edge is curved or rounded, without sharp edges, and is safer.
• Round edge processing can prevent scratches or damage to the edge during use.
• Commonly used in occasions requiring high safety and durability, such as automotive, aviation, or home appliance manufacturing.

Applicable materials: stainless steel strips, aluminum metal strips, copper strips, etc.

4. Beveled Edge

Definition: Beveled edge refers to processing the edge of a metal strip into an inclined angle, which is usually used in specific industrial applications.

Features:

• Chamfering can reduce stress concentration on the edge of the metal strip and avoid edge breakage or damage during use.
• Commonly used in applications requiring precision installation or welding.

Applicable materials: carbon steel, stainless steel, copper, etc.

5. Deburred Edge

Definition: Deburred edge refers to the edge of a metal strip that has been specially treated to remove edge burrs and make the edge smooth.

Features: No burrs, suitable for occasions with high safety requirements. The deburring process can prevent the edge from causing damage to other materials or personnel in subsequent operations.

Applicable materials: stainless steel strips, aluminum metal strips, carbon steel strips, etc.

6. Precision Edge

Definition: Precision edge trimming is an edge that has been processed with high precision and has extremely high dimensional accuracy and smoothness.

Features:

• The edge is very smooth and the dimensional tolerance is extremely small.
• Applicable to high-precision manufacturing industries such as electronic equipment, precision instruments, etc.

Applicable materials: Usually used in high-requirement materials such as stainless steel strips and copper strips.

Summary The types of metal strip edges mainly include burrs, trimming, rounded edges, chamfered edges, deburred edges, and precision trimming. Different edge types are suitable for different applications, from low-cost burrs to high-safety rounded edges and high-precision precision trimming. Each type has its unique advantages and applicable scenarios.
