The serrated steel grating is welded by flat steel with one side serrated. In addition to the characteristics and uses of ordinary steel gratings, it also has strong anti-slip ability, especially suitable for wet and slippery places, offshore oil production platforms, etc. The anti-slip serrated steel grating adopts hot-dip galvanized surface treatment, which has strong rust resistance. The non slip serrated steel grating can be used as a hinged connection between the gutter cover and the frame, which is anti-theft, safe and easy to open.
Features & Benefits
* The anti slip serrated steel bar grating is made of high-strength carbon steel, which makes the steel grating have high strength: the strength and toughness are much higher than those of cast iron, and can be used in large-span and heavy-load environments such as docks and airports.
* Has a large mesh for optimal drainage: The leakage area is 83.3%, which is more than twice that of cast iron.
* Has a beautiful appearance: Simple lines, silver appearance, modern ideas.
* Saving materials and investment: When the large span and heavy load are used, the price is lower than that of cast iron; and the cost of replacing the cast iron cover due to theft or crushing can be saved.
Serrated Steel Grating Series
Series 1 (spacing 30mm) serrated steel grating is the most commonly used type and is used in various industrial fields. The center distance of the loaded flat steel of this series of steel gratings is 30mm, which conforms to the American standard. In the whole series of steel gratings , has the strongest resistance to surface impact. It is widely used in power plants, refineries, sewage treatment plants, granaries, chemical plants, highways, airports and wharves and other platforms, walkways and gutter covers, stair treads, etc. Among them, the toothed steel grating can be used in wet and greasy places, especially for offshore oil production platforms;
Series 2 (spacing 40mm) serrated steel grating is the most economical and lightest type. It meets the specifications of fixed platforms, walkways and stairs stipulated by British standards. It is the most ideal product for occasions with small spans, even when transporting equipment aisles. That kind of load is no exception, and can also be used as warehouse shelves, pavilion panels, trestle bridges, protective fences, sun curtains, etc.;
Series 3 (spacing 60mm) serrated steel grating is specially developed for mining industry applications, it solves the problem of mineral splashing on the board. This series of steel gratings has a nominal size of 50*60mm, which allows most of the splashing material to pass through, thus ensuring the cleanness and safety of the board surface. This product is often specified for the board surface in the crushing system. , the aisle on the conveyor line and the ball mill, the processing plant and the operation station, etc.
Raw Material Composition
(1) Ordinary Flat Steel: The general material is Q235. The common models are generally 253 255 303 305 323 325 403 404 405 503 505 605 705 and other specifications. We mainly use longitudinal shear flat steel, and steel plate cutting.
(2) Serrated Flat Steel: The model is the same as that of ordinary flat steel, the difference is that one side of the flat steel has uneven tooth marks. Mainly because of slip resistance.
(3) I-type Flat Steel: The flat steel is thicker on both sides and thin in the middle.
(4) Twist Steel: Also called twisted square steel, generally 5x5 6x6 8x8 square steel, twisted steel bars.
