First of all, the requirements of the purchase and the identification of stainless steel sampling, the origin requirements of stainless steel, standard requirements and the differentiation of cold and hot rolling on the surface. Stainless steel surface acceptance includes processing requirements (such as: 8K mirror, wire drawing, film coating, oil grinding wire drawing, polishing, anti-fingerprint, embossing, color, titanium, etc.); Acceptance of stainless steel surface: whether it is scratched, rusted and processed surface grade. Stainless steel cutting processing acceptance includes opening, edge, slitting, slitting, plasma, water knife, laser cutting, punching, embossing, punching, head, cutting, semi-finished products, etc.

The procurement categories of stainless steel profiles are divided into pipe (square pipe, round pipe, industrial pipe (seam, seamless), decorative pipe, anti-fingerprint, health grade, food grade), round steel (light element, black rod), flat steel, Angle steel, square steel, hexagonal bar, channel steel (cold drawn, pickling), stainless steel microwire, coil wire, stainless steel flange, etc. Non-standard customization of stainless steel materials is divided into private steel mill rolling (hot rolling), rolling (cold rolling), cold rolled stainless steel strip customization.

Inspecting the quality of the goods is not only the right of the buyer, but also the obligation. If the buyer fails to exercise his right to inspect the quality of the goods, it may make it difficult for the seller to be held liable in part or in whole. If the quantity of the goods is large and the inspection takes a long time, the parties may choose to seal the samples for proper storage through negotiation, and agree in writing to infer the quality of the goods based on the quality of the samples. Acceptance of stainless steel tolerance is the inspection of the actual thickness of stainless steel, the difference between the diagonal of the plate and the thickness of the edge and the middle of the plate. Acceptance of the width of stainless steel plate and the width requirements after longitudinal cutting and cutting, acceptance of stainless steel length (contrast between the length obtained by opening or cutting and the actual requirements); The acceptance of the actual weighing weight error is the pound difference, the loss after processing, the sandwich paper between the sheet material, the roll, etc., the theoretical calculation pays attention to the specific gravity of stainless steel and the calculation method. The acceptance of packaging methods includes wooden frame, packing belt, paper, fumigated wood or iron frame (export packaging), etc., cold rolling requirements are strict, and the basic requirements of hot rolling are not too high.

Freight is generally paid on arrival freight method, freight one-ticket system settlement method (because the quantity of goods required by the demander and the arrival place have not been determined, the general telephone quotation does not include freight), if you need to issue an invoice, you need to give billing information in advance, whether tax is included, tax point negotiation; The mode of transport can be arranged by itself or transported by the shipper, and a transport contract is signed.

The data identification of the contract form, identification of the supplier's three certificates, identity information, alternate contact information, etc., can be photographed and kept as a record. In a long-term transaction, both parties may agree in a written contract on the electronic contact methods that can be used for the change of this transaction or subsequent transactions, such as mobile phone number, wechat signal, email address, etc.
