Features
- Precision Thickness
3 mm with ±1% tolerance ensures consistency in fabrication, ensuring perfect fit and minimal material waste for your fabrication projects.
- Hot Rolled Technique
Heating metal above its recrystallization temperature (around 1100°C for steel) and passing it through a series of rollers to deform, reduce thickness, or change its cross-sectional shape, providing a stable structure suitable for mechanical and construction applications.
- Corrosion Resistance
Stainless steel and galvanized options for humid, coastal, or semi-outdoor environments.

Customization Options
- Material Grade Selection
Choose from carbon steel (Q235, Q3455), stainless steel (304/316), or galvanized steel based on your environment and application needs, from indoor non-corrosive settings to humid or coastal areas.
- Surface Treatment Options
Select bare, oiled, galvanized, checkered surfaces, etc.
- Custom Thickness and Dimensions
Thickness (3 mm standard) and dimensions (width 1.5 m, length 6 m standard) can be adjusted to meet your specific project requirements.
- Precision Cutting Services
We offer laser cutting, plasma cutting, and shearing.
FAQ

Q: What should be considered when transporting steel sheets?
A: Proper bundling, protective padding, and container loading are important to prevent movement, scratches, or deformation during transportation.
Q: How are steel sheets protected from surface damage during shipping?
A: Protective measures such as steel strapping, wooden or rubber padding, and moisture-proof wrapping for sensitive surfaces help reduce the risk of damage during transit.
Q: What container types are typically used for exporting steel plates?
A: Steel plates are commonly shipped using 20GP or 40HQ containers, which provide sufficient capacity and protection for international transport.
Q: How should steel sheets be stored after delivery?
A: They should be stored in a dry, well-ventilated area and kept off the ground using supports or pallets to avoid moisture exposure and surface damage.
Q: What industries commonly use 3 mm steel sheets?
A: 3 mm steel sheets are widely used in construction, machinery manufacturing, building decoration, transportation equipment, and general industrial fabrication where moderate strength and easy processing are required.
