Delivery cycle: The normal delivery cycle is 40 days. If the selected specifications are in stock, contact the customer service staff of the mall to confirm;

Product information: original material list can be provided.

Product length: the products on the line are of indefinite length, and the length of a single piece is 5-7m;

Orders and settlement:

Product weight: the product is measured by ruler, and the calculation formula is as follows:

The weight of 304, 304L and 321 stainless steel pipes (kg) = (outer diameter mm - wall thickness mm) * wall thickness mm * 0.02491 * length m;

Weight of 316, 316L, 316H stainless steel pipe (kg) = (outer diameter mm - wall thickness mm) * wall thickness mm * 0.02507 * length m;

According to the required specifications and the corresponding length of the theoretical weight of the order, please note the required length of each specification. When the supplier delivers the goods, the whole piece shall be delivered to meet the required meters. The final settlement quantity shall be subject to the actual acceptance quantity, and the invoice shall be issued.

Settlement price = ex factory price + freight + special packing fee (optional) + fixed size specification fee (optional)

The online price of the mall is the ex factory price, and the freight (yuan) = basic transportation rate × traffic volume adjustment coefficient × transportation distance × order quantity, which is automatically calculated by the background of "njsc365.com" according to the freight logic. When placing orders, all units should try to place orders in a centralized manner on the premise of meeting the demand time.

The mode of frame packaging:

The specific requirements of the frame packaging method are to use channel steel and I-steel as frame materials, and tightly wrap stainless steel tubes with no less than 2 layers of woven cloth to prevent electrochemical corrosion caused by direct contact between dissimilar materials (stainless steel and carbon steel). The shelves and tubes are separated by hard plastic plates, so as to avoid the iron frame directly rubbing the stainless steel tubes during transportation. After the frame is installed, the outer package is bound firmly by three layers of plastic woven tape; Marking of lifting point and center of gravity; The weight of frame packaging should be controlled at about 2-3 tons.
