QYM-Chain Link fence

Chain link fence, also called Cyclone fences or diamond mesh fence, is made from steel wire fabrics. With variety of wire gauges and mesh size, chain link fence can be designed according to different applications. Moreover, it has the features of low cost, transparency, and easy installation. Chain link mesh rolls normally come with line wire and knuckled edges. Barbed edges are more popular and with higher security.

 

 

 

 

Note : Normally single branch crack or V type crack will be installed at top of the post, barbed wire and razor wire will be fixed at top of the fence to enhance secure class.

 

 

HK9 Glass Dome Lens

Dome lenses are hemispheres. The two optical surfaces are an equal thickness apart, creating a naturally strong shape that gets tougher under pressure. This makes dome windows ideal for underwater environments and in applications such as camera dome ports and submersible windows.
BK7 or K9L domes are used primarily in meteorology applications. BK7 offers excellent transmission from 300nm up to 2µm. BK7 is a relatively hard material, with excellent chemical durability.
UV fused silica domes ( JGS1 ): For applications operating in the deeper UV range, we offers a range of UV fused silica domes. Fused silica domes are commonly used in underwater applications at extremely high pressures.

Sapphire domes: For infrared applications we can provide sapphire domes. Sapphire is an extremely hard material with transmission of over 80% in the 2-5µm wavelength range. As with fused silica, sapphire is able to withstand extreme pressures, making it the perfect material for underwater camera and missile fairing applications.
