As you know the thickness, density and light transmission rate are critical quality factors of bullet-resistant glass. Without limit to thickness of bullet-resistant glass, it will be easy for everyone to make bullet-resistant glass by stacking glass layers as many as possible. However, The quality of bullet-resistant glass will decline with the increase of the thickness. We guarantee to provide you best quality products. For Example, G17 bullet-resistant glass can resist multiple shoots from submachine gun at distance of 10 meters; the protection-side is 1mm thin-layer glass which minimizes the spall;the light transmission rate is above 80%. All these advantages allow us to take the gobal leadership in the market of transparent armoring materials. It is wise to let our products serve you as safety guarder. We are looking forward to hearing from yo
