Stainless Steel Bar Surface Finish
Through different processing methods of cold rolling and surface reprocessing after rolling, the surface finish of stainless steel bars can have different types.
The surface processing of stainless steel pipes have NO.1, 2B, No. 4, No. 3, No. 6, BA, TR hard, Rerolled bright 2H, polishing bright and other surface finishes, etc.
NO.1
Processing type: hot rolling, annealing, removing oxidized skin
State characteristics: rough, dark
2D
Processing type: cold rolling, heat treatment, pickling or phosphorus removal
State characteristics: The surface is uniform, matte
2B
Processing type: cold rolling, heat treatment, pickling or phosphorus removal, bright processing
State characteristics: The surface is smooth and straight compared with 2D
BA
Processing type: cold rolling, bright annealing
State characteristics: smooth, bright, reflective
3 #
Type of processing: Brush film or matte finish on one or two sides
State characteristics: no direction texture, no reflection
4 #
Type of finishing: General finishing for single or double sides
State characteristics: no direction texture, reflective
6 #
Processing type: single or double matte satin line polishing, Tampico grinding
Condition characteristics: matte, no direction texture

Process of Production
The production process of stainless steel pipe needs to go through: stapling → calendering → annealing → slicing → pipe making → polishing
1. Tape booking: Prepare raw materials of steel tape in advance according to demand
2. Calendering: Use calendering machine to press the roll plate like rolling noodles and roll the roll plate to the required thickness.
3, annealing: due to the rolling plate after calendering, physical properties can not reach the standard, toughness is not enough, need to annealing, restore stainless steel properties.
4. Strip: According to the outer diameter of the pipe produced, strip it
5. Pipe making: Put the divided steel strip into the pipe making machine with different pipe diameter molds for production, roll it into the corresponding shape, and then weld it
6. Polishing: After the pipe is formed, the surface is polished by the polishing machine.
Packaging is generally naked, steel wire binding, very strong.
If you have special requirements, you can use rust proof packaging, and more beautiful.
Transportation: Express (Sample Delivery), Air, Rail, Land, Sea shipping (FCL or LCL or Bulk)
The first step in the delivery of stainless steel square tubes is to choose a reliable supplier. Look for suppliers with a reputation for delivering high-quality products on time and with a track record of meeting customer expectations. Check their delivery policies and make sure they offer flexible options to suit your needs.
Once you have selected a supplier, the delivery process begins. Suppliers will usually provide a delivery schedule based on your location, order size and any other relevant factors. This timeline should be clearly communicated to you so you can plan accordingly.
When stainless steel square pipes are ready to be shipped, they are usually wrapped with protective material to prevent damage during transportation. This may include plastic shrink wrap or cardboard sleeves. Some suppliers may also include additional cushioning material to ensure your product is not damaged during handling.
The shipping method for your Stainless Steel Square Tube delivery will depend on your location and the size of your order. For smaller orders, suppliers can use package delivery services such as UPS, FedEx or DHL. For larger orders, they may use a shipping company such as a trucking company or container service. The delivery company will provide a tracking number so you can monitor the progress of your order.
Once your stainless steel square pipes arrive, they must be inspected for any damage or defects. If any problems are found, the supplier should be notified immediately so they can correct the problem. It is important to remember that stainless steel is a highly durable material and any damage or defect could be the result of mishandling during shipping.
