How to distinguish the quality of Weifang iron packing belt

The quality of Weifang packaging steel belt is related to many factors, including its thickness, toughness, appearance and color. The quality of Weifang packaging steel belt can be judged by the following criteria. Let me introduce it to you. , The appearance, color and surface quality of the Weifang iron packing belt, put the monitored part of the Weifang iron packing belt on the platform, and use a one-meter ruler against the concave side of the Weifang iron packing belt, and measure the meter ruler to the concave side Great distance to the side.　　, the coating film thickness and galvanized thickness of the Weifang iron strapping belt are measured with corresponding precision measuring instruments. The measuring position should be no less than millimeters from the edge of the Weifang iron strapping belt, and the length should be no less than millimeters. Measure three points on each side, and the average value of each test value is the thickness of the coating film or the thickness of the galvanized layer.　　. The test items, sampling quantity, sampling method and test method of each batch of Weifang iron sheet strapping shall comply with national regulations.　　, the sample of the tensile test of the Weifang iron strapping strap should meet the requirements of GB/T. The sample of the Weifang iron strapping strap adopts a full rectangular cross-sectional shape without machining, and the original cross-sectional area is calculated according to the actual measured size. The above are the four ways to distinguish the quality of steel straps from the manufacturers of Weifang iron strapping straps. The manufacturers of Weifang iron strapping straps remind users to keep their eyes open and don't just buy inferior strapping steel straps for cheap.
