The Bluetooth parking system in the Bluetooth parking lot gate in Anhui can simultaneously satisfy the two-way IC reader and the two-way ID reader. The IC/ID is compatible with a motherboard. One board controls the entrance and exit at the same time, achieving two requirements; IC card Write sector operation, the unique IC card offline charging, reducing the dependence on the computer or the network; at the same time to achieve ID card can be run offline; can plug in the voice module, external Chinese LED display, and achieve offline control.

The charging mode with multiple embedded zones can be set freely; the operation modes of large parking lots, semi-nesting or other parking lots can be freely set; the car reading card can be set freely, and the car can be taken out; it can be perfectly controlled. The card machine automatically recovers the "invalid card", and the barrier-free Bluetooth parking system ensures that each card issued is a valid card; in the no-computer mode, the card can be authorized, reported loss, and inquiries can be carried out without computer mode. Time setting management; can be run offline without reliance on computers and networks; it can also be connected with software to realize real-time monitoring, charging, reporting and other comprehensive management. Anhui Lin Bo professional installation of Anhui Bluetooth parking barrier parking barriers / swipe barrier automatic barriers.

Duplex Stainless Steel Overview 

Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.

Today, modern duplex stainless steels can be divided into three groups:

Lean Duplex such as LDX2101

Standard Duplex such as 2205, the work-horse grade accounting for more than 80% of duplex uغير مجاز مي باشدe

Super Duplex such as Ferralium 255 and  Zeron 100 and LDX2507

Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications.  Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
