Surface with a raised (or sunken) patterns of the plate. Reticulate pattern, also known as steel plate, is a diamond or a sudden the surface edges of the plate. Pattern can be a single diamond, or round-shaped bean-shaped lentils, but also by the pattern of two or more appropriate combination of a combination type checkered plate. Mainly from the anti-skid pattern and decoration. Combined anti-skid checkered plate capacity, flexural capacity, metal content and appearance of conservation areas such as the combined effect, are much better than a single type of checkered plate. Tread plate is widely used in shipbuilding, boilers, automobiles, tractors, railway cars and construction industries. Tread plate surface because of its sudden edge, non-slip effect, can be used as flooring, plant escalators, pedal frame work, ship deck, the car floor and so on. Tread plate for the workshop, large equipment or the ship corridors and staircases of the pedal, the surface pressure of the diamond-shaped pattern of the plate, or lentils. Ordinary carbon steel plate from steel production, 1-3 B, thickness of 2.5-8 mm, width 600-1800 mm, a length of 2000-12000 mm. The specifications of the basic pattern plate thickness (excluding the thickness of conflict edges) that are 2.5-8 mm in 10 specifications. Diamond Plate Steel with a 1-3. Diamond Plate High is not less than 0.2 times the thickness of the substrate; tread plate theory based on actual weight or the weight of delivery; Tag example: made by Q235-A, size is 4 * 1000 * 4000mm. Circle bean pattern plate, mark it as: bean-shaped pattern of circular steel Q235-A-4 * 1000 * 4000-GB / T 3277-91 diamond tread plate, which is marked as: diamond pattern steel plate B 3-4 * 1000 * 4000-GB 3277-82 to hot-rolled steel plate state of delivery; tread plate surface may not have bubbles, scarring, tensile, folding and inclusion, not a layered plate. Surface quality is divided into two levels: Normal Accuracy: steel surface with thin oxide skin allowed, rust, iron oxide skin off the rough surface formed by the ancient and the height or depth than the other local fault tolerance. Obvious pattern on the allowed maximum height of the burr and a high profile individual marks. The maximum area of a single defect does not exceed the square of a long pattern. High accuracy: steel surface with thin oxide skin allowed, rust, and height or depth of not more than half of the thickness tolerance of other local defects. Pattern intact, allowing a high degree of pattern on the thickness tolerance of not more than half of the local minor glitches. Tread plate steel grades by GB/T700 (carbon steel), GB/T712 (hull structural steel) and GB/T4171 (high weathering steel) provides supply, B ordinary carbon structural steel rolling, chemical components within the GB700 "ordinary carbon steel technology" requirements. Present, because of growing demand for domestic construction, the above three types of structural steel required an annual output of 10% -15% per year, in the Shougang Group, Anshan Iron and Steel and other large steel mills, led by some of the emerging domestic steel mills, such as Puri steel is also extremely rapid development momentum.
