Rack-type grating plates are a special type of steel grating with a serrated surface, offering excellent anti-slip, corrosion-resistant, and high-load-bearing properties. They are widely used in industries, transportation, construction, and marine fields.Below is a detailed introduction to the toothed grate plate:
I. Features
1. Excellent anti-slip performanceThe serrated design of the toothed grille effectively prevents slippage, particularly in moist or greasy environments such as offshore oil drilling platforms, chemical factories, and food processing plants, significantly reducing the risk of falls.
2. High corrosion resistanceThe toothed grating plates are commonly treated with hot-dip galvanizing, forming a dense zinc layer that effectively blocks air and moisture, preventing rust on the steel, and are suitable for long-term use in various harsh environments.
3. High-bearing capacityThe toothed grating plates are made of high-strength carbon steel, offering exceptional strength and toughness, far exceeding cast iron. They are suitable for environments with large spans and heavy loads, such as docks and airports.
4. Excellent ventilation and drainage performanceThe perforated design of the toothed grille panels allows for a larger water leakage area, reaching up to 83.3%, which is more than double that of cast iron, benefiting ventilation and drainage.
5. Economical and efficientThe toothed grating plate boasts high strength and rigidity while also being relatively lightweight, which aids in reducing overall weight and pressure on the supporting structure. Additionally, galvanizing is an economically efficient surface treatment method that effectively extends the service life of the grating plate.
6. Easy to clean and maintainThe hot-dip galvanized surface of the toothed grille plate is less prone to dirt, making it relatively easy to clean and has a lower maintenance cost.
Section II: Application Fields
1. Industrial SectorThe toothed grating plates are widely used in platforms, walkways, drain covers, and stair treads of factories, warehouses, refineries, and wastewater treatment plants, ensuring the safety and efficiency of workers.
2. Transportation FacilitiesRack and pinion grating panels are suitable for constructing pedestrian overpasses, crosswalks, and other traffic facilities. The toothed design ensures anti-slip safety for pedestrians.
3. Petroleum and chemical industryThe corrosion-resistant properties of the toothed grille plates make them suitable for use on oil and chemical equipment, capable of withstanding corrosion from harmful substances.
4. Marine EnvironmentIn damp environments such as ocean docks and ports, our toothed grating plates can withstand saltwater corrosion, maintaining long-term stable performance.
5. Architectural DecorativesThe design of the toothed grating panels adds a unique element to the building's exterior, suitable for decorating stairs, railings, and the like, while also meeting anti-slip requirements.
Section 3: Categories and Specifications
1. CategoriesThe toothed grating panels can be categorized according to different standards such as flat steel shape, application, and welding method. For instance, they can be classified into flat type, toothed type, and "I" type based on the flat steel shape; and into general-purpose steel grating panels and specialized steel grating panels for specific uses like manhole covers and step plates.
2. SpecsThe flat steel height of the toothed grille plates typically ranges from 20mm to 50mm, including 25mm, 30mm, 32mm, 35mm, 40mm, 45mm, and 50mm; the flat steel thickness options are 3mm, 4mm, 5mm, 6mm, and 8mm. Custom design is available according to specific requirements.
