What is B-Grade?
Same quality.
Minor cosmetic differences.
B-Grade surfaces are structurally identical to A-Grade. The only differences are minor cosmetic imperfections that are typically invisible once installed — saving you 30–40% on material costs.
These surfaces undergo the same quality control, carry the same certifications, and perform identically in every technical test. The "B" simply means less-than-perfect appearance.
