How to categorize the characteristics of various storage shelves
Super shelves because of the thousands of types, categories are more than a hundred kinds of it, this can not talk to you in detail, but also can not write. Can say, but also only storage shelves, and ordinary storage shelves, high-end automated three-dimensional library, that the standard is to write a book are not enough.
Storage shelves quality standards are also many, from the load-bearing, design, specifications, technology, materials and so on.
Load-bearing aspect: depends on your needs, because according to the different load-bearing, shelves are divided into light shelves, medium-sized shelves, heavy-duty shelves. Different specifications have different designs, specifications. This load-bearing refers to the standard four shelves can withstand the weight of each layer. Light shelves generally load-bearing 100-180 kilograms or so, medium-sized shelves generally load-bearing 200-350 kilograms or so, heavy-duty shelves generally load-bearing 500 kilograms or more. The higher the weight, the higher the quality requirements, of course, the better the quality, but you put some light things, buy 500 kilograms of shelves that are a bit of a waste. If the pursuit of quality, the highest selection to medium-sized shelves on the line, after all, now the light shelf market is too chaotic, too heterogeneous, especially on the Internet, dare to mark, but the quality is estimated to put thirty kilograms up will collapse. The big factory brand shelves in their own standard load-bearing there is a safety factor, some are 1.2, some are 1.3, individual brands are 1.6 higher, that is, the load-bearing more than the nominal weight of 1.6 times the short term will not be a security risk. Long-term may cause some deformation but to ensure that it does not collapse and cause accidents. At present, I know of only Hercules brand in the north can reach this standard, the south has three or four to reach this standard.
Design: the current domestic market design standards are particularly chaotic, many manufacturers of light shelves of C-beam butterfly hole shelves square a big one into a medium-sized shelves and even heavy-duty shelves, do not look at the safety factor. Of course, there are individual large factories, big brands, the traditional heavy-duty and even ultra-heavy-duty (load capacity of one ton) shelves to the design standards for heavy-duty shelves and medium-sized shelves, the most typical example is the medium-sized shelves of the Hercules, with the U-beam columns and hawksbill card, increase the thickening of the safety pins. Put it this way, U-beam and C-beam, the same thickness of the height of the case, U-beam column steel is almost 1.3 times the amount of C-beam column to 1.5 times the amount of structural safety is more than two times. In addition to the column, in the cross brace diagonal brace, Hercules medium-sized shelves are also used with the same ultra-heavy-duty shelves on the 10 thick and thin to strengthen the stainless steel screws, rather than the majority of manufacturers with the welding method, the degree of solidity of more than three or four times as strong as the individual manufacturers of horizontal and diagonal brace welded to the side of the point of one point, the two small weld fiddling with the matter of the hand can be made off by breaking a hard hand.
Specifications: mainly look at the various parts of the material thickness (not before the paint on the pure steel material, many manufacturers use the thickness of the paint to fool people), good quality columns are generally 0.4 from the light shelves, 0.6 from the medium-sized shelves, which are the lowest minimum standard, in fact, theoretically, the light shelves should be 0.6 from the medium-sized shelves is 0.8 from. Other parts of the material thickness should also be noted. Of course, the column is the most critical part of the shelf load-bearing, the main consideration, the thickness should be considered together with the design structure, U-beam structure, general 0.8 mm thickness specifications, than the C-shaped steel 1.0 or even 1.2 of the actual load-bearing are high, of course, the weight is also more heavy, so many shelf manufacturers are using C-shaped steel columns, save just now, good processing, but also appears to be a large thickness, the cost of the rest of one-third more. Another, the thickness of the paint should also pay attention to, 0.8 mm thickness of the plate after painting thickness of about 1.2, many manufacturers paint the thickness of the fool, after painting is 0.8 millimeters, in fact, 0.5 is not bad, and also certainly not a good spray paint.
Craftsmanship:In this regard, in fact, can say not much, the big manufacturers of good craftsmanship, quality control strict some. Can say is two, one is degreasing rust, one is a molding. Large manufacturers, or strict quality manufacturers, degreasing and descaling is operated with a special pool, a row of pools, degreasing pools, descaling pools, acid and alkali pools, phosphate pools and so on several steps, each step is a strict immersion for forty minutes to see the effect of the effect is satisfactory on the near water pools rinsing, 40 minutes to enter the next step, if the effect is unsatisfactory but also in the 40 minutes. Each step is done to clear water rinsing 40 minutes. So a set down almost need a day or more. Small factories, including some large factories now use the method is the production line spray, a set of half an hour down to get it done, the effect of it, I guess only one-third of the immersion, the appearance of the look is okay, but a lot of corners, parts of the interior simply can not be dealt with, so the life of the imaginable. I know, I saw more than a hundred factories in the north, only Hebei Walker Metal's Hercules brand is still operating in the way of soaking, hundreds of factories in the south, only three, dozens of southern are soaking, but now they are changed to spray, after all, the time to save a dozen or so, the cost of one-tenth of a percent reduction. A molding is mainly a test of machinery, large factories can buy high-grade machinery, shelves, seven or eight different angles of the direction of the bend in a molding to do out, to ensure that the best state to retain the material, small factories can only use ordinary machinery, a processing of a bend, seven or eight bends processed seven or eight times, resulting in too much fatigue of the metal, but also seriously affects the quality.
Last material: large factories are used in high-quality cold-rolled steel, small factories with miscellaneous steel, and even do not use steel. This is currently also peers, especially online publicity counterfeiting the most places, I remember last week with a large factory in Nanjing, the boss of the online chat, he said, a lot of peers open and shut with the Baosteel steel, but the price of his set of shelves are not worth the Baosteel steel money, and even some of the price is less than half the price of the steel, do not want to make money peers are doing a public service with the raw material cost of half of the price of finished products, that half of the price of steel, the price of steel, the price of steel, the price of steel. Finished product prices, that half of the cost of steel prices, staff costs, plant costs and other costs are the boss of their own pockets for nothing? I have dinner with the manager of the Hebei Walker metal also talked about this matter, he said, they definitely use good cold-rolled steel, but they have the same load-bearing medium-sized shelves, the cost of many counterparts more than double, and some even double, resulting in their online sales performance is very dismal. I was also curious to search online, Hercules medium-sized shelves then a specification of more than 600 yuan a set of counterparts with the standard 299, their manager said that now they sell online in order to go, do not profit is compressed in more than 500, which is the cost price, but also can not be more competitive counterparts, this phenomenon in the shelving industry is indeed a big problem, it is worth thinking about the problem, our country has a lot of insist on Our country has a lot of manufacturers adhere to the quality of manufacturers, including the Nanjing and Hebei I said this, but they are now survival has become a problem, in order to survive, they mainly rely on exports, because foreigners to buy things is to look at the quality of the first look at the price. These two are currently doing very well in foreign trade, especially Hebei Walker, Europe, the U.S. market to do a lot of large projects, high-end. I look at which medium-sized shelves, domestic sales and foreign sales of the same standard the same warehouse the same batch of goods sold abroad than at home, and much better. I remember that the manager was very depressed, he is now considering whether to meet the needs of domestic customers, to produce a number of low-quality, low-priced goods to meet domestic demand. And Nanjing which old boss also said similar words, although now there is export support, these two just have the idea, have not really go to the production of the so-called domestic quality products they are not willing to do to reduce costs, but later?
