- Q:Aluminum alloy rolling doors and color steel shutter door that good
- The material and structure design Aluminum Alloy rolling shutter door out of the ordinary, can effectively prevent glare and ultraviolet radiation, sunlight greenhouse effect on indoor has completely solved, applicable to all kinds of changes in climate and weather, has a long-term protective effect on indoor environment, tests show that the shutter doors and windows to keep out sunshine rate to 100%, the the rate can reach more than 95% block temperature.
- Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
- In order to prevent rusting in the process of storage or transportation of steel roll, steel mills generally take the following packing: inner gas antirust paper wrapped with tape wrapped in plastic film sealing, intermediate, involute cardboard seal lining, cardboard corner, with iron and steel outer package corner protector, strapping fixed. If the inner package seal, so the steel coil is sank into the water, will not rust out.
- Q:Why cold rolled stainless steel sheet is lower than cold rolled stainless steel coil?
- 304 stainless steel coil 2.0*1219*C spot price 18 thousand and 100 / ton, general tolerance at about 1.8mm.Coil price * actual thickness / reference thickness = flat price1.81*1.8/2=16.29
- Q:The difference between aluminized color steel roll and ordinary color steel roll
- Substrate selection: AZ150 (aluminum zinc content 150g/m2); G345A high strength galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon) corrosion resistance data: 5%NaCL 35 DEG C, 1000Hrs, Field good, Scribe, No, Blister, 2mm belowQ.U.V: 2000hrs, MAX.2 color, light to keep the rate above 90%, the above data show that aluminum zinc coated board (AZ150, G345A, PVDF) is very suitable for the extreme environment of buildings or other facilities, highly corrosion resistance and weather resistance, and the major steel plate can ensure the service life of 20 years. In addition, high strength steel has been widely used abroad, and it has good economic performance, and it is also the domestic development trend.
- Q:Several reading methods of steel tape measure
- Precise steel tape factory and after a period of time must go through the verification and indicate the verification of temperature, tension and feet. Feet marked on the length of its nominal length, and the difference between the actual length is called length correction delta l ruler by different tension will make feet long. To avoid this change requires the use of steel tape according to the scale mark force of steel tape. At different temperature the foot will change with the temperature so it is necessary to use t as variable function to represent the feet long, this is the ruler length equation, its general form:
- Q:How can the outer diameter and weight of steel coil be converted?
- When it comes to this question, in fact, a lot of them are irrelevant. The weight of the steel rolls means that there is a unit weight called the weight of each mm in the width of the steel coil
- Q:What is the accuracy of steel tape inspection
- In addition, the project is through the detection of steel tape, steel tape each batch have the error him different, so do projects each into a batch of steel tape has to go through the inspection department, let this batch of steel tape has reached the same error range. All the measuring tools in this project are unified into these steel tape measures, so that the measurement error is guaranteed
- Q:Why can hot rolled coils be placed outside?
- Because hot-rolled steel coils are generally used as raw material for semi-finished products, they have to be further used for pickling and cold rolling to make more use. The rust and dust can be removed after pickling
- Q:What's the best material for color coated steel coil?
- Galvanized steel sheet with hot-dip galvanized or zinc plated surface.
- Q:A roll of 1 meters wide color steel roll about how many tons?
- Generally speaking, it will be about 4 tons, the export may be larger, but 10 tons of papers have not yet seen
