1.5-3.0mm 304L Stainless Steel Coil with 2B Finish for Corrosion Resistant

The 304L stainless steel coil is a versatile low-carbon stainless steel material designed for manufacturers requiring corrosion resistance, weldability, formability, and consistent surface quality.

This product is supplied in a 1.5-3.0mm thickness range, with standard widths including 1000mm, 1219mm and 1500mm. The primary finish is 2B, providing a smooth, clean, and uniform surface suitable for industrial fabrication and further finishing.

304L belongs to the 300 series stainless steel family and is particularly well-suited to components requiring extensive welding or forming. Compared with conventional 304 stainless steel, its lower carbon content makes it a preferred option for many welded fabrications.

The material can be supplied as a full coil or processed into customized sizes. Available services include decoiling, cutting, bending, punching and welding, helping customers reduce secondary processing requirements.

Stainless steel used in fabrication must satisfy more than basic corrosion-resistance requirements. Manufacturers may need a material that can be:

• Formed without excessive difficulty
• Welded with reliable results
• Processed into accurate dimensions
• Maintained with a consistent surface appearance
• Used in humid or mildly corrosive environments
• Adapted to different fabrication processes

Using an unsuitable grade can increase production costs and create problems during welding, forming, or subsequent surface treatment. For this reason, 304L stainless steel is frequently considered when both material performance and fabrication efficiency are important.

The cold rolled manufacturing route is also advantageous where customers require more uniform surface and tighter dimensional control than normally associated with hot rolled material.

Our 304L stainless steel coil provides a practical material solution for manufacturers, fabricators, and construction suppliers. The product combines the properties of 304L stainless steel with cold rolled processing and a 2B surface, making it suitable for a broad range of downstream applications.

• Reliable corrosion resistance - Offers good resistance to atmospheric corrosion and many common industrial environments
• Excellent welding characteristics - Low-carbon composition makes it suitable for welded assemblies and fabricated structures
• Good forming performance - Can be processed through bending and other forming operations with correct tooling and parameters
• Consistent surface quality - 2B finish provides smooth and uniform surface for general industrial and decorative applications
• Flexible processing options - Customers can request cutting, decoiling, bending, punching or welding according to production needs
• Suitable for customized orders - Thickness, width, coil dimensions and processing requirements can be discussed per project

Our stainless steel processing facilities are equipped for large-volume production and customized processing.

• Production capacity: More than 100,000 tons per year
• Rolling equipment: 20-high reversible rolling mills
• Annealing: 5 continuous annealing lines
• Slitting: 15 slitting lines

Quality control focuses on dimensional accuracy, surface condition, material identification and traceability. For qualified orders, customers can also request samples and technical support before bulk production.

304L stainless steel coil can be fabricated into structural components, architectural panels, frames, trim, roofing elements and interior building products. Its clean appearance and corrosion resistance make it suitable for many architectural environments.

The 1.5-3.0mm gauge range is suitable for manufacturers producing metal enclosures, brackets, frames, covers, cabinets and fabricated components. The material can be cut, bent, punched and welded according to design requirements.

304L can be used for selected worktables, sinks, food-processing equipment, storage units and commercial kitchen components, provided the final application meets applicable sanitary and food-contact requirements.

Depending on service conditions, the material can be used for equipment housings, tanks, machinery parts, processing equipment and general industrial components.

For projects requiring decorative appearance, 304L can be further processed into brushed, hairline or polished surfaces. The standard 2B finish can also serve as the starting surface for additional finishing operations.

The performance of 304L stainless steel is mainly related to its alloy composition. The chromium contained in stainless steel reacts with oxygen and creates a very thin protective film on the metal surface. This passive film helps limit further oxidation and gives stainless steel its characteristic corrosion resistance.

Nickel in the alloy contributes to ductility, toughness and corrosion resistance, while the low carbon level of 304L provides an important advantage during welding.

During welding, stainless steel can be exposed to elevated temperatures. In conventional stainless steel grades, excessive carbon can contribute to chromium carbide formation in certain conditions. 304L contains a lower level of carbon, reducing this tendency and making it well suited to many welded stainless steel fabrications.

Cold rolling is performed after the hot rolling stage to reduce material thickness and improve dimensional characteristics. The process can provide:

• More accurate thickness
• Better width consistency
• A smoother surface
• Improved flatness
• A suitable base for subsequent surface treatment

After appropriate annealing and finishing, the material can be supplied with the specified 2B surface.

Before purchasing a stainless steel coil, buyers should evaluate several factors rather than selecting the grade based solely on price.

For ordinary construction and general fabrication, 304L can be an effective choice. For environments containing higher levels of chlorides or aggressive chemicals, 316L or other higher-alloy grades may be more appropriate.

For this product, the recommended range is: 1.5mm / 2.0mm / 2.5mm / 3.0mm. A thicker gauge may be preferable where greater rigidity or structural strength is needed, while thinner material can reduce weight and material consumption.

Standard widths include: 1000mm, 1219mm and 1500mm. Customized widths can be considered when the customer's production line requires specific dimensions.

2B is a practical choice for general manufacturing. Choose BA when a brighter appearance is required. Choose NO.4 or HL for brushed decorative applications. Choose 8K when a highly reflective mirror appearance is required.

If the material will go directly into production, customers should specify whether they require: Coil → Decoiling → Cutting → Bending → Punching → Welding. Providing these requirements before production can help optimize final material dimensions and reduce processing waste.
