Mourões: a cada 2-2,5 m. Travessas: 2-3 por seção. Tábuas: conforme largura. Para 30 m em eucalipto: ~13 mourões + ~210 tábuas + 10%. No Brasil, eucalipto autoclavado é o padrão econômico.

Custos

Eucalipto: R$100-200/m linear instalada. DIY materiais: R$50-100/m. 30 m: R$1.500-3.000 DIY.

⚡ CalcWolf Insight

The most common fence failure: inadequate post depth. Posts should be 1/3 below ground (minimum 24 inches for a 6-foot fence) and set in concrete. Gravel-only posts lean within 2-3 years. Concrete costs $3-5 per post and adds decades to fence lifespan. This is not the place to cut corners.
