Buying Tips

Preços no Brasil

Caibro pinus 5×5 cm, 3 m: R$15-25. Viga 6×12 cm, 3 m: R$30-50. Tábua de deck cumaru 2×10 cm, 2,40 m: R$25-50. Eucalipto tratado: a opção mais econômica para estrutura. As madeiras nobres brasileiras (ipê, cumaru, jatobá) são premium mas duráveis por décadas sem tratamento.

Dicas

Planeje os cortes para usar comprimentos padrão (3,00 e 4,00 m). Compre em madeireira, não em home center — preços 20-40% menores. Eucalipto autoclavado é a melhor opção custo-benefício para exteriores no Brasil.

⚡ CalcWolf Insight

The best time to buy lumber is late fall/winter when construction demand drops. Prices typically peak in spring (building season starts) and trough in November-January. Planning ahead and buying off-season can save 10-20% on materials.
