The surface material determines the board's lifespan and erasability. For heavy-duty use, Porcelain (Ceramic) surfaces are the gold standard as they are scratch-resistant and ghost-free, often coming with a 25-year warranty. For standard office use, Painted Steel offers a balance of cost and performance with magnetic properties. For budget-friendly or short-term needs, Melamine is an option, though it is prone to 'ghosting' over time. For a premium aesthetic, Tempered Glass boards provide a modern look, are extremely durable, and compatible with high-end interior designs.
