Strategic development

Star Good Steel Co., Ltd. The main products have?

In line with the mission of "to provide you with high quality steel service", to "high quality results achievement future" business philosophy, and "make high quality steel become world famous iron and steel company" vision. High-quality steel is mainly composed of steel, building materials, steel plate, steel coil, cold-rolled plate, hot-rolled steel plate, galvanized steel, seamless steel pipe, high-frequency welded pipe, precision steel tubes, color coating (plate) composition, special steel, stainless steel series, as well as the production of ferrous and non-ferrous metals.

Second, how to identify high quality industrial steel profile?

Generally there are several aspects:

1, the thickness of the steel plate

2, the surface of steel quality appearance

3, the rust on the surface of the steel

4, steel weight

5, conditional sampling inspection

The simplest method is to guarantee of quality. Look at the factory with the test indexes.

Construction steel to identify

New to a group of building rebar; Check whether and the demand of diameter, length, quantity, weight and other relevant information.

Delivery of information and purchasing information is consistent, packaging and the quantity of purchasing a quantity to whether consistent; In conformity with the weighing measuring whether or not.

Strapping label in conformity with the demand of commodity attribute; Macroscopic observation information in conformity with the commodity attribute.

The physical inspection report

1, to qualify for purchasing information consistent attributes of goods. Shougang products cannot be hangang inspection report.

2, physical standard must be clearly qualified words or other form of determining words and chapters have sealed by the inspection report and inspection report.

3, test time and corresponding factory aging; Corresponding to the production enterprises and report.

Photographic experience check

Use the method of spark identification.

The required equipment: grinder

With alumina grinding wheel

Methods: 1. To start the grinder, will be inspected workpiece with standard samples are sharpening respectively, contrast can be quickly separate spark.

2. If there is no material samples. The workpiece in the grinding wheel in sharpening, manganese steel feel hard, streamline white or yellow-bright infusion. Popcorn and orderliness, thin white mans line, much pollen when carbon content is high.

Industrial pure iron feel is soft, fire flower long and almost entirely to flow, don't burst day flower. Wheat yellow.

The spark of cast iron, cast iron is very short, the color is dark yellow, dark red, spark and finely is very small, much pollen.
