Rockwool insulation board buyer acceptance criteria? Dacheng Xiangdong Insulation Refractory Material Factory 13473696600 157316144481, Appearance Quality: The surface is flat, and there must be no scratches or stains that impede practical use.
Tempered Glass is often used in applications where using standard glass could pose a potential danger. Tempered glass is stronger than standard glass and does not shatter into large shards when broken. This is important, because it can greatly minimize potential danger in the case of a break. Manufactured through a process of extreme heating and rapid cooling, tempered glass is much harder than normal glass.
In the case that tempered glass does break, it shatters into small pebbles that are void of dangerous, sharp edges. As tempered glass is considered to be much safer than normal glass, you may often here it referred to as safety glass or TOUGHENED GLASS . Tempered glass has a wide variety of uses that you'll find just about everywhere. In fact, the shower doors in your bathroom or the side glass on a motor vehicle are examples of tempered glass.
Annealed float glass mainly clear float glass, ultra clear float glass, color tinted glass, they are substrate, can be processed into tempered glass, Laminated Glass , Insulated Glass , LOW-E glass, Frosted Glass , Back Painted Glass, Printed Glass , coated glass. Tinted glass mainly brown, grey, blue, green, and also black, black is less. It can be processed into color tinted tempered glass, Colored Laminated Glass, Colored Insulated Glass and so on on customer's request., can be used for windows, doors, glass walls, fence, railing, shower room, furniture, industrial and so on.
