Every industry has its own little secrets. There are many pits hidden inside.

1.Passing off inferior materials as good ones: Common materials for stainless steel include201and304The prices of the two differ by nearly double. A kind of stainless steel detection solution can be bought.10-15It costs one yuan per bottle. This way, the materials used can be tested. Multiple parts need to be inspected; otherwise, the outer frame might be used304Internally, it's still201Materials.

There are various testing solutions on the market, and one of them is...

2.Insufficient material thickness: The requirement is1.0mmThick. It's possible that it uses0.85mmThe requirement is3.0mmThick, it might be used2.5mm.So the actual thickness needs to be indicated. Usually, the error of two threads is within the normal range. As required1.0mmThick, practical0.98mmThick. It belongs to the normal error of the material.

3.There are many brands of stainless steel raw materials, and there are also material differences among different brands. Contain18%The above chromium,8%The materials with the above nickel content are excellent. The low quality is due to insufficient content of important components, which affects the corrosion resistance and strength performance. For those with high quality requirements, the brand of materials can be specified.

4.Surface treatment process. Surface treatment processes include sandblasting, polishing, sandblasting, color plating, and etching patterns, etc.

Nowadays, the industrial chain is segmented, and each process is completed by one factory. If all the above processes are needed, several factories need to cooperate together. No company in the industry can independently complete all the above processes. The cost of industrial chain segmentation is lower.

The key point is how merchants control the quality details. For example, in the case of sandblasting, it can be brushed twice, as this will make the luster of the silk texture stronger. Mirror polishing, divided6kor8kBrightness (The surface of the usually purchased glossy tubes is.6KGlossiness. The higher the glossiness, the higher the cost. The stainless steel plate is machine-polished to achieve this8ＫThe cost is not high either. The products are hand-polished. The higher the glossiness, the greater the cost will be.

When checking the quotations from merchants, it is necessary to see if they match the quality requirements.

5.Welding process

It is usually divided into spot welding and full welding. Full welding means that all the connection positions on the front are welded and ground. Spot welding is side welding, while the connection line is retained on the front. Both welding techniques are aesthetically pleasing, but the labor cost of full welding is much higher. If the grinding of full welding is not smooth, the effect will be inferior to that of spot welding. Full welding, some of the welding points may deform. It belongs to unqualified welding and grinding.

The left picture shows full welding, while the right picture shows spot welding with the front gap line retained.

Spot welding or full welding, as long as the craftsmanship is good, both look good.

5.The exaggeration of quotations and the trap of low prices

If the quotation is inflated, in fact, you can compare the quotations from several more companies. However, some factories offer relatively low quotations in order to obtain orders. This may cause the price you quote to Party A to be insufficient. After the order is placed, if the factory finds that it cannot be produced, it will ask for a price increase. Otherwise, it will refuse to accept the order. This way, for you who have already received the order, it will be rather passive.

6.The delay of the construction period

This is a common problem in the industry. In the production process, different procedures require the cooperation of multiple factories. When one factory is busy, it will be delayed, resulting in an extension of the entire order time. The originally agreed time may not be accurate, so placing an order in advance is the best way to avoid it.

7.The electroplated color on the surface of the product

Problems are prone to occur in the electroplating process of products. The larger the size, the more likely there are problems.

The color is different from the color palette and there are also color differences. There are problems such as discoloration and easy color fading at the corners. The degree of this difference depends on the level of different electroplating factories. The photos don't look good or bad. You must look at the real thing. Placing the color palette on the product and taking photos together can also be used for comparison. Common colors in the attached picture:

Some textures of stainless steel materials:

Dispute resolution

Customized stainless steel projects are prone to various problems, such as dimensional errors, misunderstandings in communication, unreasonable deepening structures, and mismatches between stainless steel and the site. In disputes, people often stand on their own side. It should be agreed in advance that the factory is responsible for any communication misunderstandings. Any unauthorized modification of the plan without prior notice shall be the responsibility of the factory.

Contract issue

The simpler the contract is, the more often disputes arise where there are no agreements. It is necessary to supplement the previously mentioned construction period, color, structure and size. The more detailed, the better.

Inspection issues

Most factories require payment before shipment. It is best to inspect the goods on site before making the payment.

It's best to inspect the goods at the electroplating factory. You can go there right after electroplating and before packaging, and then conduct a full inspection. After packaging, random inspection is the only option. Some customers don't want to come and inspect the goods because it's far away. In fact, even if you fly from Beijing to Foshan and pre-order in advance, it only costs a few hundred yuan per trip. A single order can easily cost tens of thousands of yuan. It's still worth making a trip.

Common stainless steel customized products for hotel decoration include screens, coffee tables, columns, handles, lines, flower POTS, guardrails, doors, etc.

The stainless steel market is now mainly concentrated in the two trading markets of Chen Village, Li Yuan and Jin 锠.

The stainless steel hardware accessories market is still located in the area of the International Metal Market in Chancheng District

The accessories are mainly sold in the stores on both sides of the road. In the picture, the purple line on Liming Road, the yellow line on Jinlan South Road, and the green line on Lanshi 2nd Road all sell and wholesale stainless steel accessories.
