1. Product specifications are special. The thickness is 8~50mm, the width is 150-625mm, the length is 5-15m, and the product specification is relatively dense, which can meet the needs of users. Instead of the middle plate, without cutting, it can be directly welded. 2. The surface of the product is smooth. The high-pressure water descaling process is used twice in the process to ensure the smooth surface of the steel. 3. The sides are vertical and the angle is clear. The two-way vertical rolling in the finish rolling ensures that the sides are perpendicular to the sides, the corners are clear, and the surface quality of the edges is good. 4. The scale of the product is accurate, three points difference, the same level difference is better than the steel plate standard; the product is straight and the plate type is good. The finishing rolling adopts the continuous rolling process, and the automatic looper automatic control ensures that the steel is not pulled without steel. The dimensional accuracy of the product is high, the tolerance range, three-point difference, the same strip, the boring curve and other parameters are superior to the middle plate, and the plate type is straight. Good. Cold shear cutting, high length precision. 5. The material of the product adopts the national standard and is the same as the steel plate. The quality technical standards are organized according to the YB/T4212-2010 standard (Q345B/Q235B refer to GB/T1591-94 and GB/T700-88 standards respectively) Aluminum Coils,Polished Aluminum Coil,Aluminum Coil for Coating Ling Feng Aluminum Co., Ltd. , http://www.nbaluminum.com
