The material of the sandwich panel directly affects the later use. Sandwich panels are the main building materials for Prefabricated House and Steel Structure Warehouse. If you want to choose high-quality panels, you must have an understanding of their basic quality. There are many types of boards on the market, and their core materials, steel plates, adhesives, etc. are different, and the quality will also be affected. So how to judge its pros and cons?
check edge
Because the sandwich panel has several layers, it is difficult to judge its internal quality from the surface. Therefore, it is still necessary to observe its exposed edges first, and it is necessary to pay attention to whether its cross-section is clean and ensure that it is tight. If there are problems such as graying and impurities, then there must be problems in quality, so it is still necessary to do a good job of cross-sectional inspection.
Tap to hear the sound
If it is a relatively good board, you can simply tap it with your fingers. If the sound is a crisp metallic sound, then it is a relatively good board. The fire rating of the Rock Wool Sandwich Panel is Class A, and the fire rating of the polyurethane sandwich panel and Eps Sandwich Panel is B1.
Note the thickness
The thickness of the sandwich panel directly affects the long-term use in the later period. It is necessary to observe the substrate, peritoneum, etc., especially the thickness and quality of the coating, which we cannot ignore. It is necessary to choose a plate with a relatively thick coating and guaranteed quality. Generally, the thickness of the substrate should be about 0.4-0.8MM. If you see the real thing, you should also measure it. The thickness of the finished product is 50mm, 75mm, 100mm, 150mm. The bulk density of the core material is also an important link that affects the quality.
certificate
In fact, as long as it can cooperate with regular manufacturers, the plates sold by the manufacturers need to go through various inspections, and the quality must meet the regulations. Therefore, when purchasing, you can directly check whether it has a certificate of conformity. If you choose a plate from a regular manufacturer, you can not only enjoy a preferential price for direct sales from the manufacturer, but also enjoy good after-sales service.
Now there are many manufacturers supplying plates, and the market quotations and quality of each manufacturer are also different, so it is still necessary to do a good job of quality comparison and price measurement. It is suggested that when purchasing sandwich panels, one must pay attention to its specific quality, and compare the quality of the actual products in order to select high-quality panels.
African rose pear resource shortage prices continue to rise, companies find their way out
As Africa's timber resources have started to show signs of depletion, the rising cost of imported timber has become a common trend across the continent. However, the price of African rosewood has recently surged by at least 20%, directly impacting the pricing of our African rosewood products. Based on the current supply and demand dynamics for African rosewood panels this year, it is expected that prices could spike significantly next year due to continued shortages.
African rosewood, a rare species, is rapidly declining in availability, which has led to increased prices for furniture and flooring made from this material. Countries like Benin in West Africa are also reducing their export volumes of African rosewood panels, contributing further to the price hikes. Traditionally, March and April are peak months for customs clearance for African rosewood, but as we approach the end of the year, there remains uncertainty about when shipments will be cleared. African rosewood is primarily sourced from Africa and is considered a mid-to-low grade material in the premium wood category, with one ton priced below ten thousand yuan. It is widely used in the production of high-end furniture.
Due to limited wood supplies, the domestic market has seen a shortage of hedgehog rosewood, causing its price to increase by approximately 20%. Despite the sharp rise in wood prices, many domestic timber merchants who have been waiting for shipments for extended periods are not pleased at all.
One merchant from Xiamen, specializing in mahogany furniture, mentioned that several cabinets were still piled up at the Gambia port. This situation ties up significant capital, and because no new shipments have arrived, some orders cannot be completed successfully.
The pressure from rising prices has prompted some domestic companies to consider increasing their product prices. Following an initial price hike at the start of the year, a major furniture brand manufacturer is now planning to raise prices again next year. The timing and extent of the increase are still under discussion. Additionally, other manufacturers producing African rosewood products have begun to follow suit. According to officials from the China Wood and Wood Products Distribution Association, the cumulative price increase for African rosewood over the past three weeks has exceeded 60%, with a 20% to 30% rise in the last two weeks alone. Importers are feeling considerable pressure, and the upward trend is expected to continue, with predictions of a 60% to 70% increase next year.
The rising costs have placed immense financial strain on domestic companies. Some African rosewood products have already seen a 10% price increase, and these adjustments continue to reflect the growing cost of raw materials. Reports indicate that panic buying of African rosewood products has already begun in first-tier cities such as Beijing and Shanghai. Clearly, enthusiasts are rushing to purchase before prices climb even higher.
Faced with the pressure of rising African rosewood prices, companies are actively seeking alternative solutions. A Guangdong furniture producer revealed that African rosewood imports from Africa have risen by at least 30% in the past week. In addition to accepting the price increases, many companies are exploring other wood sources to mitigate the impact.
Beyond seeking alternative materials, securing upstream resources has become a key strategy for some businesses. With African rosewood becoming increasingly scarce, price hikes are inevitable. However, these pressures can be eased by improving wood utilization rates and expanding supply chains.
The ongoing resource shortages and difficulties in exporting are likely to drive further price increases, which could lead to higher production costs for African rosewood products. Industry experts believe this will raise the survival threshold for companies, pushing many small and medium-sized enterprises to either adapt or close down.
