Tread plate 
 patterned section 

 Surface with a raised (or sunken) pattern of the steel plate. 

 Tread plate, also known as textured steel, its surface with a diamond or a sudden edge of the plate. 

 The pattern can be a single diamond, lentil-shaped or round bean-shaped, and can also be a combination type of checkered plate pattern appropriate to combine two or more. 
 The pattern is mainly from the anti-skid and decorative role. Combination checkered plate anti-slip, flexural capacity, saving the combined effect of the amount of metal and appearance, were significantly better than a single type of checkered plate. 
 The tread plate is widely used in shipbuilding, boiler, automobile, tractor, train cars and construction industries. 
 Tread plate due to its surface a sudden edge, non-slip effect can be used as flooring, plant escalator, working pedals, ship deck, car floor. 
 Tread plate for a workshop, large equipment, or ship walkways and stairs pedal, the surface pressure of the diamond or lentil-shaped pattern of steel plate. 
 Plate is the production of ordinary carbon steel 1-3 (B) steel, the thickness of 2.5-8 mm, width 600-1800 mm, length of 2000-12000 mm. 
 The specifications of the tread plate base thickness (the thickness of the sudden edge of being disregarded), 2.5-8 mm and 10 kinds of specifications. Diamond Plate Steel Plates 1-3. 
 Diamond Plate high not less than 0.2 times the substrate thickness; 
 The tread plate delivery by actual weight or theoretical weight; 
 Tag example: Q235-A made the size 4 * 1000 * 4000mm. 
 Round bean tread plate, tag it: bean-shaped circular pattern steel plate Q235-A-4 * 1000 * 4000-GB / T 3277-91 
 Diamond tread plate, tag it: diamond tread plate panels B, 3-4 * 1000 * 4000-GB of 3277-82 
 Delivery; plate to the hot rolled condition and tread plate surface without air bubbles, scarring, fracturing, folding and inclusion, shall have layered steel plate. 

 The surface quality is divided into two: 
 Ordinary accuracy: the steel surface to allow a thin layer of oxide scale, rust, rough surface due to the formation of oxide scale off and height or depth of the ancient local defects exceed the allowable deviation. The pattern allows the obvious glitches and a height of not more than a pattern of high individual traces. The maximum area of ??a single defect does not exceed the square of the length of pattern. 
 High precision: the plate surface allows thin layer of oxide scale, rust, and the height or depth of no more than half of the thickness tolerance of local defects. 
 Pattern intact pattern allows a height of not more than half of the thickness tolerance of the local minor glitches. 
 Tread plate steel grades according to GB/T700 (carbon structural steel), GB/T712 (hull structural steel) and the supply of provisions GB/T4171 (high weather resistance of structural steel), B ordinary carbon structural steel rolling, The chemical composition accords with GB700 "ordinary carbon structural steel technology conditions" requirements. Due to the growing demand of domestic construction set forth above three structural steel production rate of 10% -15% per year increase in Shougang, Angang, a number of large steel mills, led by some of the emerging domestic steel mills, such as Puri steel and other extraordinarily rapid development momentum.
