Technical-grade Sheet Glass

High quality flat glass and plate glass

Technical grade sheet-glass, flat glass and plate glass materials are fabricated by using the float-glass process or they are drawn as glass-sheets. They are usually clear and transparent and feature smooth and transparent, fire polished surfaces. All our transparent sheet-glass materials are available with different standard thicknesses and at a low nominal sheet thickness tolerance. In order to use it for an optical application, in most instances our high quality technical grade sheet-glass doesn't even need an additional polishing process. Most of these transparent glasses can be CNC-cut very precisely, which is resulting in considerable cost savings to the customer and lower cost of the end product. Almost all of the listed technical quality flat glass types feature a very smooth surface, a good optical flatness, a display grade surface quality plus a low micro roughness. Especially the micro roughness of our flat sheet-glass materials often is better than what can be achieved by a standard mechanical polishing process. Hence, some materials shown in this category are the best choice for large production series. They offer both, a superior glass quality and the cost control required. Below, please find the links to our technical grade flat sheet-glass types that are part of our extensive glass delivery program. Please follow the links to the respective data-sheets to view the specifications and to view the typical optical transmission curves of each sheet glass below:

Why is there no shopping cart, no price and no standard size on our website?

The simple answer is: We don't need a shopping cart and standard sizes. We are as quick with the manufacturing of custom sized parts as most trading companies typically are with their few and limited standard sizes. You will find a RFQ button in each of our data-sheets to conveniently request for a quotation for the sheet-glass you need. You usually get your price quote as well as the the delivery of custom-sized sheet-glass even at large quantities within an extraordinarily short period of time. For most materials even a 48h-Express Service is available to you.
