Wooden grilles: Precision in spacing and cross-section

A high-precision wooden slat screen. Each slat has a cross-section of three by four centimeters of solid wood, with all four surfaces treated identically; the spacing is precisely four centimeters, with minimal error from top to bottom; the top and bottom ends are embedded into recessed grooves in the ceiling and floor, with no visible fixing hardware. Light passes through from behind, casting a row of equally spaced parallel shadows on the floor. The wood is knot-free straight grain. Avoid: uneven spacing of slats, using thin wood strips and hollow materials, exposing screws and battens at the top and bottom ends, using slats of inconsistent thickness.

一片高精度的木格柵屏風。每一根櫃條的斷面是三公分乘四公分的實木,表面四個面都經過相同的處理;間距是精準的四公分,從頭到尾誤差極小;上下的收頭嵌進天花與地面的凹槽裡,看不到固定的五金。光從後方透過來,在地面投下一排等距的平行影子。木材是無節的直紋。避免:讓櫃條的間距不均勻、使用薄的木片與空心材、讓上下收頭外露螺絲與角料、使用粗細不一的櫃條。
