Gully gratings are metal or plastic grates that are used to cover and protect gully openings in the ground. These openings are typically found along roadsides, sidewalks, or other areas where water runoff needs to be collected and directed to a drainage system.
Gully gratings come in various shapes and sizes to accommodate different gully openings and flow rates. They can be square, rectangular, or circular in shape, and may have different patterns or designs on their surface for aesthetic purposes.
Overall, gully gratings play a crucial role in managing surface water runoff and preventing drainage system blockages. They provide both functional and safety benefits, making them an essential component of urban infrastructure.

Due to the country's domestic demand and strong exports, the inventory of diammonium in the United States remained low in May, only 251,000 short tons, a decrease of 27% from the previous month and a decrease of 51% year-on-year. In May, diammonium production increased 6% from the previous month to 617,000 short tons, but consumption was 709,000 short tons, and the export volume decreased by 25% from the previous month to 443,000 short tons, but it was still normal. It is worth mentioning that the number of U.S. export destination countries has increased, of which exports to India are only 57,000 short tons; exports to Brazil are the largest, 133,000 short tons; exports to Mexico are very impressive, reaching 35,000 short tons . The export volume to Argentina was 54,000 short tons, the export volume to Peru was 27,000 short tons, and the export volume to Guatemala was 26,000 short tons.
In the United States, the amount of monoammonium inventories fell by 23% to 334,000 short tons in May. One of the reasons was that output fell by 12% to 378,000 short tons. Consumption fell by 8% qoq to 479,000 short tons. Exports to Canada increased by 195,000 short tons to 43,000 short tons, exports to Argentina were 48,000 short tons, exports to Brazil were 70,000 short tons, and exports to Colombia were 11,000 short tons.
Gully gratings are designed to allow water to flow through while preventing larger debris, such as leaves, trash, or rocks, from entering the drainage system. They are usually made from durable materials like cast iron or galvanized steel to withstand heavy loads and resist corrosion.
In addition to their functional purpose, ductile gartings, cast iron gratings are also provide a safety measure by preventing pedestrians or vehicles from accidentally falling into the gully. They are often designed with anti-slip surfaces or raised edges to enhance traction and prevent accidents.
Regular maintenance of gully gratings is important to ensure they remain clear of debris and allow for proper water flow. This may involve periodic cleaning or removal of any obstructions that may accumulate over time.
Ammonium Phosphate Stocks Drop Sharply
According to the latest data provided by the American Fertilizer Institute, the stocks of ammonium phosphate in the United States declined in May. According to industry insiders, the sharp decline in the inventory of this traditional phosphorus fertilizer exporting country may lead to panicked advance purchases by importing countries, thus driving up the price of ammonium phosphate in the international market.
