Is there any standard for the number of steel packages and how many quantities are per piece? Extra

This is actually an uncertain number, a bundle of steel bars is about 2 to 2 tons, for example, the same diameter of steel bars, there are 9 meters of length and 12 meters of length of two kinds, the weight is close to the number of roots must be different, this as long as you know an approximate number. When it should be purchased for you, it will not be bought by the root. Moreover, the packaging situation provided by different manufacturers is also different, and it may be arranged according to the actual situation according to the weight and convenience of transportation.

If you have to find such an answer, it is estimated that there will not be any more accurate results on the Internet, rather than you waiting for the answer on the Internet, it is better for you to find a few manufacturers that sell such products, and it is much faster and more accurate to ask than if you wait on the Internet.

These are the requirements of each steel mill when packing under normal circumstances, and it is not a standard. In the long run, various merchants will form some habits.

It still depends on what the situation is, if the export is loaded, there must be corresponding industry norms, if it is domestic retail, then there is no norm at all!

For example, how many angles are there in each piece? How many pieces of 16A channel steel are per piece? 12 How many threads are per piece? The more complete the better, and it would be appreciated to find relevant information or details!!

Listen to the sound, appearance, color, check the diameter, check the grade; The grade of ordinary hot-rolled rebar consists of HRB and the minimum yield point of the grade. H, R, and B are the first letters of the three words "hotrolled", "ribbed" and "bars", respectively. Hot-rolled ribbed steel bars are divided into HRB335 (old grade of 20mnsi), HRB400 (old grade of 20mnsiv, 20mnsinb, 20mnti), HRB500 three grades, a total of 3 grades, the higher grade is the highest grade, Rebar origin and quality:

Shagang, Rizhao is the best (standard) and then the next grade Zhongtian Xicheng in the next grade such as Fuxin and the like to see the color, [url=77] in the use of caliper card size, the purchase of tea is not easy, in order to get good tea, you need to master a lot of knowledge, such as all kinds of tea grade standards, **and**, as well as tea evaluation, inspection methods, etc.

There are generally several aspects:

1. Thickness of steel plate.

2. The surface appearance quality of the steel.

3. Rust on the surface of the steel.

4. Steel weight.

5. Conditional sampling inspection.

The easiest way to do this is to get a quality assurance certificate. Take a look at the inspection indicators at the time of delivery.

Identification of construction steel.

a new batch of rebar for construction; Check whether it matches the required diameter, length, quantity, weight and other relevant information.

Whether the information delivered is consistent with the information purchased, and whether the amount of packaging is consistent with the quantity purchased; Whether it is consistent with the weighing measurement.

whether the bundled label is consistent with the required commodity attributes; Whether the information observed by the naked eye is consistent with the attributes of the product.

Physical inspection report.

1. It is necessary to conform to the commodity attributes of the procurement information. Shougang's products cannot be Handan Steel's inspection report.

2. The physical standard must have a clear qualified word or other form of determination word, and be stamped with the inspection report seal and the inspector's report seal.

3. The inspection timeliness corresponds to the factory timeliness; The manufacturer corresponds to the report.

Photosensitivity experience check.

Use the spark identification method.

Equipment required: Grinder.

With alumina grinding wheel.

Method:1Start the grinder, grind the workpiece to be inspected and the standard sample separately, and quickly separate the sparks.

2.If there is no material sample. The workpiece is ground on the grinding wheel, the manganese steel feels hard, and the streamline is white or yellow. The bursts are numerous and neat, the miscanthus line is white and slender, and there is a lot of pollen when the carbon content is high.

Industrial pure iron has a soft feel, long spark bouquets, almost all of them are streamlined, and there is no bursting knots. Color: Wheat yellow.

The sparks of cast iron and pig iron are very short, the color is dark yellow and dark red, the sparks are small and small, and there is a lot of pollen.

At a glance, look at the appearance, look at the size and appearance of the color, the specifications are neat, the size is standardized, according to the properties of the steel, the general good steel, the surface has no impurities, and the color is uniform.

Second, look at the hardness, the hardness of the steel is not the same, according to the hardness properties of the steel, to judge, whether it is the steel you need, whether there is any difference in quality. Three looks, look at the size, inferior steel, uneven, different sizes, size fluctuations, use a micrometer or tape measure to measure, see the size fluctuation. Fourth, look at the elasticity, the toughness and elasticity limit of steel are different, and the surface of inferior steel will have cracks and poor elasticity.

Five looks, look at the nameplate of the steel, a good steel factory, the nameplate specification, express clearly, the parameter data is evidence-based, look at the quality report of the steel, whether it is standardized, unified with the properties of the steel, and corresponding to their own requirements.

Six take a look.

Look at the appearance, look at the size of the specifications and the appearance of the color, the specifications are neat, the size is standardized, according to the properties of the steel, the general good steel, the surface has no impurities, and the color is uniform.

Look at the hardness, the hardness of the steel is not the same, according to the hardness properties of the steel, to judge, whether it is the steel you need, whether there is any difference in quality.

Look at the size, inferior steel, uneven, different sizes, size fluctuations, use a micrometer or tape measure to measure, see the size fluctuation.

Looking at the elasticity, the toughness and elastic limit of steel are different, and the surface of inferior steel will have cracks and poor elasticity.

Look at the nameplate of the steel, a good steel factory, the nameplate is standardized, the expression is clear, and the parameter data is based on evidence.

Look at the quality report of the steel, whether it is standardized, unified with the properties of the steel, and corresponding to your own requirements.

Listen, experienced, can be distinguished according to the business of steel, good steel, clear sound, no noise.

These are the specifications of section steel materials, it is recommended that you take a look at the general provisions of this specification GBT2101-2008 section steel acceptance, packaging, marking and quality certificate, you can find the qualified standards of steel in this specification. This one that will help you a little bit, look at a few more, and which one can be played.

I wish you a successful transformation soon.

For you, the most practical and simple way to judge is required.

1 See if it is a fixed length or not.

2. Conduct a sampling inspection of the steel, weigh the weight of each steel, you ask him the model of the material you use, check the theoretical weight of the national standard on the Internet, calculate it, and see how big the negative difference is.

3. When looking at the quality assurance sheet (material list) of steel, it is often impossible to see this. It is estimated that they are all profiles of our small factory in Tangshan. Material Q195-Q235 But if the negative difference is less than 10% of the national standard, it should be no problem, and these materials are still used in power towers.

Use up to 15. **Cheap.

Buy steel and consult me, I'll provide you with some information, I know too much about steel, and there is the easiest way: you ask those who provide you with steel, and ask him how much money is sold by weighing or measuring scale. As soon as you analyze it, you will understand.

The negative difference of the profile is within 10%, which is very good compared with the national standard.

There are two kinds of 12 I-beams, one is the national standard, the other is aggravated, what you say is 6m, one is to tell you, one way is to take out one and weigh it.

The theoretical weight of the I-beam 12 is aggravated.

But this is the weight of the national standard, and when you bring the scale, it will definitely be lighter than this, as long as it is not too different.

You said I-beam, channel steel, etc., collectively referred to as "section steel", the above two are mainly to see its waist high waist thickness, leg height and leg thickness, under normal circumstances, as long as its actual weight per meter is closer to the theoretical weight, it is more formal, and you can't check the material. Look for this hardware manual and you'll understand.

Chemical Bolt ??? Haven't heard of it. It's an expansion bolt.

Last time I bought a non-standard angle steel, very cheap, buy standard is very expensive, the two are very different, mainly depending on the size of the standard, in fact, if the requirements are not strict, buy non-standard cheaper.

At present, there are many brands of stainless steel pipes on the market for sale and use, and it is difficult for laymen to identify the quality of the goods, which gives some stores the opportunity to deceive users, but using some simple methods to identify the quality is actually very effective. The corrosion resistance of stainless steel is mainly determined by the content of chromium and nickel, and the higher the content, the less likely it is to rust, such as Yuehua and Jingliang. The nickel content of the SUS304 tube in the center is between 8% and 10%, and the chromium content must be between 16% and 18%, so it is not easy to rust.

At present, the nickel content of 201 sold in the market is only 1%, and the chromium content is only 12%, so it is more prone to rust. But the difference between the two is more than doubled. As long as the user uses some stainless steel solder joint pickling solution (also called washing molten steel) to coat the surface of the steel pipe, if the pipe surface does not change color, it is not easy to rust.

On the contrary, if it turns black faster, the worse the quality, and it is easy to turn black and rust. Therefore, the so-called 201 pipe can be guaranteed for decades without rust, which is all a lie of the store. To keep the surface rust-free, it is possible to keep the surface from rust by scrubbing it frequently.

Therefore, I hope that you will not only choose the best picture, but ignore the quality, and choose some products that are more well-known than teaching.

In today's society, the use of money has covered all areas, and there is money everywhere, although there are things that cannot be done with money, but with the help of money, it can be done more easily.

Money is not everything, but no money is.

Money can buy a woman, but it can't buy love.
