Stainless Steel Coil Surface Finish

The surface treatment of stainless steel coils is very important, which directly affects the appearance, corrosion resistance and applicable fields of stainless steel coils. Common stainless steel coil surface treatments include 2B, BA, NO.4, etc.

2B surface treatment is the most common one, with better brightness and smoothness, and is suitable for most applications with general requirements, such as construction, furniture, etc.

BA surface treatment is obtained by electrolytic polishing, and the surface finish is higher. It is suitable for occasions with high surface finish requirements, such as kitchenware, electrical appliances, etc.

The surface treatment of stainless steel coils is critical to its final application and performance. Common stainless steel coil surface treatments include 2B, BA, NO.4, etc.

2B surface treatment is the most common one, with better brightness and smoothness, and is suitable for most applications with general requirements, such as construction, furniture, etc. This treatment method uses surface pickling after cold rolling to make the surface smoother, but it does not have a mirror effect.

BA surface treatment is obtained through electrolytic polishing. The surface finish is higher and shows a mirror effect. It is suitable for occasions that require high surface finish, such as kitchenware, electrical appliances, etc. This treatment provides excellent appearance and corrosion resistance.

The NO.4 surface treatment is obtained by belt polishing, and the surface shows a frosted texture. It is suitable for occasions that require decoration and anti-scratch, such as decorative panels, elevator interiors, etc. This treatment method can increase the decorativeness and beauty of the stainless steel coil, while improving its wear resistance.

In addition to the above common surface treatment methods, stainless steel coils can also be customized according to customer needs, such as mirror polishing, wire drawing, etc., to meet the special needs of different fields. Therefore, choosing the appropriate surface treatment method for stainless steel coils is of great significance to the final performance and application of the product.

Process of Production

The production process of stainless steel coil is: raw material preparation - annealing and pickling - (intermediate grinding) - rolling - intermediate annealing - pickling - rolling - annealing - pickling - leveling (finished product grinding and polishing) - cutting, packaging and storage .

Packing and Transportation

The crating and packaging of stainless steel coils are important links to ensure product transportation safety and protect product quality. Typically, the cartoning and packaging of stainless steel coils follows the following steps:

First of all, stainless steel coils need to undergo strict quality inspections before being packed into boxes to ensure that the surface is free of scratches and contamination, and meets customer requirements and standards.

Secondly, select appropriate packaging materials according to the specifications and quantity of stainless steel rolls. Common packaging materials include wooden pallets, cartons, plastic films, etc. For large stainless steel rolls, they are usually packed in wooden pallets to ensure that the products are not squeezed and deformed during transportation.

Then, stack the stainless steel rolls neatly on the packaging materials, and take appropriate protective measures, such as reinforcing wooden pallets, wrapping with plastic film, etc., to prevent collision and damage during transportation.

Finally, the packaged stainless steel coils are marked and recorded, including product specifications, quantity, production date and other information, and clear identification labels are attached to the packaging for easy identification and management.

During the entire crating and packaging process, it is necessary to operate in strict accordance with relevant standards and requirements to ensure that the stainless steel coils are not damaged during transportation and to ensure that the quality and integrity of the product reaches the customer.
