3mm Steel Strip
Keywords:
Product Details
3mm steel strip refers to a metal strip with a thickness of 3 millimeters, commonly produced from stainless steel or carbon steel coils through slitting and cutting processes. It is widely used in structural parts, machinery components, construction reinforcement, and industrial fabrication.
Although the thickness is fixed at 3mm, steel strips are available in a wide range of widths and lengths depending on different application requirements.
Common Width Range of 3mm Steel Strip
The width of 3mm steel strip varies significantly based on industrial usage and processing needs. Narrow strips are used for precision parts, while wider strips are used for structural and heavy-duty applications.
Typical width range:
| Thickness | Common Width Range | Application Type |
|---|---|---|
| 3mm steel strip | 10 mm – 600 mm | Industrial and structural use |
Common Standard Width Sizes
In practical production and supply, 3mm steel strip is usually available in standard widths to match processing equipment and fabrication requirements.
Frequently used widths include:
10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 40 mm, 50 mm, 60 mm, 80 mm, 100 mm, 150 mm, 200 mm, 300 mm, 400 mm, 500 mm, and 600 mm
These standard sizes are widely used in mechanical processing, construction projects, and industrial manufacturing.
Common Length Forms
3mm steel strip can be supplied in different forms depending on customer requirements.
It is commonly available in coil form for continuous processing or cut-to-length strips for direct use in fabrication and assembly.
Coil form is preferred for large-scale production, while fixed-length strips are used for ready-to-install components.
Stainless Steel Grades Used for 3mm Steel Strip
3mm steel strips can be produced using different stainless steel grades depending on performance requirements.
Common materials include 304 stainless steel for general corrosion resistance, 316 stainless steel for marine and chemical environments, 430 stainless steel for cost-sensitive applications, and 201 stainless steel for decorative and indoor use.
Each grade affects corrosion resistance, strength, and application suitability.
Surface Finish Options
3mm stainless steel strips are available in different surface finishes depending on application needs.
Common finishes include 2B smooth industrial surface, brushed finish for decorative use, mirror polished surface for architectural applications, and matte finish for industrial components.
Surface selection impacts both appearance and corrosion resistance.
Applications of 3mm Steel Strip
3mm steel strip is widely used in industrial and structural applications due to its strength and durability.
Common uses include machinery components, construction reinforcement parts, structural brackets, automotive components, fastening systems, and industrial fabrication projects.
Its relatively thick structure makes it suitable for load-bearing and high-strength applications.
