Grainy Details. The raw sheet has a natural micrograin direction that runs parallel to the 144-in. sheet length. This micrograin impacts the design in terms of strength and appearance. Bends that run perpendicular to the material's natural grain require slightly more pressure than those running parallel to the grain.
