Stainless steel market on an upward trendThe market, especially for steel and stainless steel, is currently continuing its upward trend. Supply problems are being reported from the European, North American, and in some cases also South and Central American steel markets.Steel prices have increased significantlyPrices for steel and stainless steel have increased significantly. Some are even talking of a doubling. Delivery times for European steel producers are already six months or more. – so at least in August.Market safeguard measures pose problems for the processing industryWhat is currently bringing the review of the Safeguard measures by the EU Commission and the political events surrounding it into focus in the steel world. There are now strong calls from the processing industry for an end to Safeguard.United States with all-time highs for steelSteel prices in the United States are also reaching new all-time highs and availability is more than limited. The economy in the United States has rebounded and market sources told us that things are currently going crazy there and there is hardly any material to be had.South America also feels the rising prices,In South America, the consuming industry complains of the same suffering. Severe shortages. New material is not yet in sight. And prices are rising sharply. In between, one hears voices from time to time that want to talk down the problem. But at the moment, domestic steel producers are completely overwhelmed and cannot keep up with demand.What about stainless steel imports from Asia?“Imports from Asia would currently be an alternative for many companies. But here, too, it is currently a question of readiness to make decisions and speed. And the right knowledge about where to get material and how to import it properly.The supply chain has not yet returned to normalThe supply chain to and from Asia has not yet fully recovered. There are still not enough containers available where they are needed. The shortage of ships and containers is also reflected in the price. Ocean freight rates have increased eightfold in some cases (European mills significantly increase alloy surchargesAlloy surcharges are up significantly again for March 2021.

According to data from a research report on the access control market by Marketsandmarkets, the access control industry is expected to grow from USD 7.5 billion in 2018 to USD 12.1 billion in 2024, with a compound annual growth rate of 8.24%. The main driving factors for the growth of the access control market are the increase in the global crime rate and the increase in user adoption of access control solutions; the second is the deployment of wireless technologies in security systems and the deployment of security systems based on IoT security systems and cloud computing platforms Universal application.The report pointed out that access control system as a service (ACaaS) applications, based on the widespread use of mobile access control, coupled with the gradual increase in urbanization in emerging countries, combined these factors to provide access control vendors with a broad market. Among them, biometric card readers are expected to grow at the highest compound annual growth rate in the next five years (2019-2014), including fingerprint recognition, iris recognition, and face recognition. Due to the increasing demand for security from government facilities, factories, power stations, defense agencies, and enterprises, biometric card reader have the best development period.Researchers predict that in the vertical market, the RFID access control market for family residences will have the highest compound annual growth rate in the next five years. In the smart home system, the access control system is mainly used to improve security. The key factors that promote the growth of this market are the rising global crime rate and the continuous advancement of technology. The current user demand for fire and gas leak detection is increasing. To ensure the safety of children and the elderly at home. At the same time, the growing guide home market is also promoting the upgrade of access control solutions from another dimension.Increasing security issues will drive users' demand for door access control systems in the Asia-Pacific region, so this region is also regarded as the region with the highest compound annual growth rate in the future. Factors such as industrialization, commercialization, and increasing demand for security systems have become key factors in the development of the market. In addition, compared with other regional markets, the rising crime rate and the inconsistency of police deployment have also caused users to have more access control systems. demand.Author:Written by Ms.Anna Zhang from S4A INDUSTRIAL CO.,LIMITED

S4A New year holiday's Notificationif you have any questions or require technical support during these days, pls kindly email back to: sales@s4a-access.com Wishing you health, wealth, and happiness in the New Year ahead.Author: Written by Mr.Juan from S4A INDUSTRIAL CO.,LIMITED

With the rapid development of China's economy, people's attention to security issues has prompted the rapid development of China's security industry market. The social security situation caused by the process of economic development is also worrying. The ever-widening gap between the rich and the poor has caused the crime rate in developing countries to rise, and the demand for controlled access systems in society is also increasing.At present, the integration of entrance and exit systems with monitoring, anti-theft alarm, and intercom systems is the general trend, and the boundaries of the four security systems are becoming more and more blurred. The four security systems all rely on computer software integration platforms, including access control and parking lot management systems. The integration of the entrance and exit system and the intercom system also started.If you want to check the demo software,pls contact S4A right now!The access control system and the parking lot system are collectively called the entrance and exit control system. As the name suggests, it is a system that controls the entrance and exit passages. Where to let certain people, refuse certain people, when to sound an alarm, and remember the process of entering and exiting to achieve control Security purpose. It is developed on the basis of traditional door locks. The traditional mechanical door lock is just a simple mechanical device. No matter how reasonable the structural design and how strong the material is, people can always open it by various means. It is very troublesome to manage the keys in the passages where a large number of people enter and exit. If the key is lost or the personnel are replaced, the lock and key must be replaced together.In order to solve these problems, the emergence of electromagnetic locks and electronic code locks has improved people's management of entrances and exits to a certain extent and made the management of channels enter the electronic age. However, with the application of these two electronic locks, Their own defects are gradually exposed. The amount of information stored by the magnetic stripe is small, the contact card and the card reader are worn out, and the failure rate is high. The problem with the magnetic card lock is that the information is easy to copy and the safety factor is low.In recent years, with the development of proximity card technology and biometric technology, the access control system has developed rapidly and has entered a mature period. Induction card access control systems, fingerprint access control systems, iris access control systems, and finger vein recognition access control systems have appeared. , Face recognition access control system, out-of-order keyboard access control system, and other technical systems, have their own advantages in security, convenience, ease of management, etc., and the application fields of access control systems are becoming wider and wider. As the usage...
