The serrated step steel grating is welded by the serrated flat steel on one side. In addition to the features and uses of ordinary steel grating, it also has strong anti-skid ability, especially suitable for wet and greasy places, offshore oil production platforms, etc. The serrated steel grating adopts the hot-dip galvanizing surface treatment, which has strong rust resistance. The product can be used to connect the ditch cover and the frame by hinge, which is anti-theft, safe and convenient to open.
The serrated steel grating is made of high-strength carbon steel, which makes the steel grating have very high strength: the strength and toughness are much higher than that of cast iron, and it can be used in long-span and heavy load environments such as docks and airports. The product has a large mesh and the best drainage: the leakage area is 83.3%, more than twice that of cast iron. Beautiful product appearance: simple lines, silver appearance, modern ideas, material saving and investment saving: when large span and heavy load, the price is lower than that of cast iron; and the cost of replacing cast iron cover due to theft or crushing can be saved.
Raw material composition of serrated steel grating:
Ordinary flat steel: the material is generally Q235. The common model is 253 255 303 305 323 325 403 404 405 503 505 605 705 and other specifications. We mainly use flat steel and steel plate cutting. Tooth shaped flat steel: the model is the same as ordinary flat steel, the difference is that there are uneven tooth marks on one side of the flat steel, which is mainly used for anti-skid.
Type I flat steel: both sides of the flat steel are thick and the middle is thin.
Twist steel: also known as twisted square steel. Generally, there are 5x5 6x68x8 square steel and twisted steel bars.
