The main documents of the project are shown in the following table:
After the holiday, concrete shipments bottomed out, and the capacity utilization rate increased by 133% month-on-month (data source: Centennial Construction Network)
The weekly shipments of concrete surveyed this week were 364,400 square meters, an increase of 208,000 square meters from the previous month, and the concrete shipments rebounded significantly. Sub-regional point of view: the seven major regions in the largest increase in shipments for the South China region, after the holiday downstream projects gradually resumed work, to a certain extent to promote the improvement of concrete market demand, so the concrete shipments rose significantly; followed by the southwest region, the inter-holiday suspension of concrete enterprises have opened their doors, shipments began to rise; in addition, the downstream procurement demand in central China has been restored, the concrete market has picked up, shipments increased by 271%; East China and North China shipments increased by 54% and 34% respectively, Mixing plant supply of key projects, inventory tight and capital pressure under the pressure of concrete shipments slowly rebounded; the northeast and northwest regions this week capacity utilization rate of 0.03% and 0%, affected by cold weather, downstream project construction is blocked, demand is still in a stagnant stage, after the holiday concrete shipments are difficult to improve in the short term.
This week, the number of rainy days in 145 cities in China increased, and the average number of rainy days affecting concrete shipments in the week was 0.5 days, a decrease of 0.5 days from the previous month. Among them, the rainfall in East China and Central China was greatly reduced by 1 day, and the southwest and South China regions were reduced by 0.7 and 0.06 days respectively, and the recent rainy weather in various regions was less affected, the weather improved and the temperature rebounded, and the concrete market gradually recovered after the holiday, and shipments began to increase steadily.
This week's survey of concrete enterprises more feedback problems have the following five points: 46% of the concrete enterprises feedback that the market demand is weak, the current downstream projects have not resumed work in a large area, most of the mixing station shipments have improved, but only a small amount of supply to key projects in a short period of time; 29% of the concrete enterprises feedback that the capital pressure still exists, the payment collection rate declines year-on-year, and now the enterprise still takes the collection as the main work, selectively guaranteeing high-quality projects; 13% of the concrete enterprises feedback that the material preparation situation is not good, and the raw material inventory is low. At present, the procurement pressure is not reduced, and the growth rate of shipments in a short period of time is limited; 8% and 4% of concrete companies feedback that due to external factors such as slow construction progress and the Holding of the Winter Olympics, there is little room for concrete shipments to temporarily recover.
The feedback from concrete enterprises in key areas is as follows:
East China region
Fujian concrete enterprise feedback: only one of the projects received has resumed work, the daily shipment volume is about 80 parties, the mixing station is not positive about the recovery of market demand this week, and it is believed that short-term market demand will slowly pick up.
Zhejiang concrete enterprise feedback: at present, normal production has resumed, but due to the small number of downstream construction projects to resume, it has not yet returned to normal levels, and the current average daily shipment is about 2,000 square meters, and it is expected to return to normal levels from the end of February to the middle of March.
Feedback from Anhui concrete enterprises: At present, it has not opened its doors for business, and there is no shipment. Tomorrow will start business, but the shipment volume in a short period of time is not large, only sporadic projects are being done in the downstream construction, on the other hand, the financial pressure still exists, and the lack of start-up funds.
Feedback from Shandong concrete enterprises: On the 16th, the company started construction, and the downstream market project started earlier, but the construction site operation was less, and it is expected that the order volume this week will not be much. In terms of payment collection, it is basically flat compared with previous years, and if the payment collection in the first quarter is less than expected, it will actively reduce the supply.
Central China region
Henan concrete enterprise feedback: in recent days, the average daily shipment of about 200 square meters, the surrounding construction sites do not start much, the current supply of prepayment customers, for the years before the poor payment of customers, temporarily do not intend to supply.
Hunan concrete enterprise feedback: at present, the mixing station has begun to operate, but the downstream project has not yet started, the mixing station has not yet shipped, it is expected that the project will start after the fifteenth of the first month, and the mixing station will immediately begin to supply.
Feedback from Hubei concrete enterprises: After the first ten years, the mixing station resumed business, and the shipment volume in recent days has been increasing, and the weekly shipment volume has not exceeded 2,000 square meters.
South China region
Guangdong concrete enterprise feedback: twelve started, has been normal shipments, the daily average of five hundred square, is expected to fully resume work around the twentieth of the first month, the poor return of funds compared to other mixing stations is acceptable, not due to financial problems should be shipped.
Feedback from Guangdong concrete enterprises: workers have basically arrived, a small number of shipments will begin tomorrow, and this week will gradually resume work, and projects with an impact on funds may not be actively supplied after years.
North China region
Feedback from Beijing concrete enterprises: At present, it has not yet opened and produced, and it is planned to resume production after the end of the Winter Olympics on the 21st. The attendance rate of concrete employees is less than 20%, and it is expected to return to work around the 20th.
Feedback from Tianjin concrete enterprises: At present, it has been operating normally, with an average daily shipment of about 200 square meters and a weekly rate of about 1200 square meters. At present, demand has not yet rebounded, and shipments are expected to increase significantly at the end of February.
Feedback from Shanxi concrete enterprises: planned to open tomorrow, no shipments this week. In the short term, the demand for concrete market is difficult, and the focus of work after the holiday is still the payment collection, and it is expected that shipments will increase significantly in mid-March.
Southwest region
Sichuan concrete enterprise feedback: In February, the downstream demand is less, the mixing station has been opened, the office staff have arrived, the downstream demand is less, the average daily shipment is only 100-200 square meters, due to the poor payment situation, the current hoarding is not much and is also stepping up the payment collection.
Yunnan concrete enterprise feedback: last week there was no order, there is no volume, this week began a small amount of goods, the daily average is expected to be 400-500 parties, market demand has not risen.
Northwest Region
Shaanxi concrete enterprise feedback: the enterprise has not started construction, is expected to resume work on February 8, but in view of the surrounding market site has not yet started, it is expected that the full production will be extended to around February 15.
Shaanxi concrete enterprise feedback: is currently in the raw material storage stage, sand plants have started, but the procurement pressure is still very large, raw material inventory is at a low level, this week sporadic project supply, the daily average of 800 square meters.
The average capacity utilization rate of concrete this week was 1.82%, which was higher than expected. Shipments increased 133% sequentially. This week, except for the northwest, shipments in other regions have rebounded, of which South China and Southwest China have the most obvious increases. The fifteenth day of the first month has passed, the construction projects have begun one after another, and it is expected that the utilization rate of concrete capacity will rebound to about 4% next week. The North China Winter Olympics have not yet ended, and it is expected that shipments in North China will have a large room for recovery.
Sample description: The current round of research time is 2.10-2.16 days, the total sample volume is 506 concrete mixing stations, the regional proportion: East China 23.28%, Central China 16.43%, South China 17.12%, North China 21.23%, Southwest 15.1%, Northwest 2.7%, Northeast 4.14%; Capacity Utilization Rate = Weekly Output / Weekly Design Capacity; The Normal Average Capacity Utilization Rate of Concrete Enterprises Remains At About 30%.
