Specifications
Products can be supplied in pre-cut manner, cut into stick (Sandwich slat), fiber is vertical usedSandwich Panel Rock-wool Core Material
Product Introduction
BST sandwich panel rock-wool core material is designed specifically for sandwich board of metal surface, and the fiber direction of the rock wool should be perpendicular metal board when using, to make a strong compressive, tensile and shear strength. Rock wool fiber is composite with the metal surface by bonding. This vertical fiber structure makes the sandwich board has a high compressive strength, high shear and tensile strength characteristics, which can be widely used as sandwich core material in mental surface, such as large span or high-level applications of building facades, walls, roofs, partitions, ceilings and high loads sandwich board, and the fire door industries etc.
Products can be supplied in pre-cut manner, cut into stick (Sandwich slat), fiber is vertical used, to increase fiber peel strength. Besides, for the users who have cutting device, supplied with the entire board, self-cutting, and then overturned used (rock wool board).
