Cut To Sizes Because of our strict mounting grade requirements, all chipboard we keep in stock is flat and smooth. Some mill products have warp and can be skewed. For white-lined board, the stock used is 70# coated text. The list below shows the type and sizes of chipboard we have in stock. We can cut these to any size your job requires. To place an order for chipboard or to request a price on cut sizes, email info@graphiccraftsinc.com or call 717-464-2733, ext. 24.
