When choosing an outdoor table material that can withstand martens, durability and resistance are key. Martens are known for their sharp claws and curious nature, often damaging softer materials like wood or plastic. The best options include:

1. Powder-Coated Metal: Resistant to scratches and chewing, powder-coated steel or aluminum tables are a top choice. The coating adds an extra layer of protection.

2. Composite Materials: High-density polyethylene (HDPE) or recycled plastic composites are tough, non-porous, and unattractive to martens.

3. Concrete or Stone: Heavy and nearly indestructible, these materials deter martens from climbing or gnawing.

4. Tempered Glass: While less common, thick tempered glass tables are smooth and unappealing to martens.

Avoid untreated wood or wicker, as martens can easily damage them. Opt for materials that combine strength with low maintenance for a long-lasting outdoor solution.
