TikZ - Clipping the squares ring

Very quick eyeballing solution

\documentclass[tikz]{standalone}
\usetikzlibrary{shapes.geometric}
\begin{document}
\begin{tikzpicture}
\clip[postaction=fill] (0,-2) rectangle (8,2);
\foreach\x in{1.5,0,-1.5}{\foreach\y in{-4,...,4}{\draw[white,thick](0,\x+ 0.1*\y)--++(8,0);}}
\foreach \x in {0,...,8}{
  \node[diamond,minimum size=1.5cm] (n-\x) at (\x, 0) {};
  \draw[draw=white,double=black, double distance between line centers=2mm,line width=1mm] 
  ([shift={(-135:3mm)}]n-\x.east)--(n-\x.east)--(n-\x.north)--([shift={(45:5mm)}]n-\x.west)
  ([shift={(-135:5mm)}]n-\x.east)--(n-\x.south)--(n-\x.west)--([shift={(45:2.2mm)}]n-\x.west);
  \draw[thick] ([yshift=0.21cm]n-\x.north) -- ([yshift=-0.21cm]n-\x.south);
}
\draw[thick](0,0)--++(8,0);
\end{tikzpicture}
\end{document}

Maybe more complete option but with some tricky elements, and some patterns issues like diferent rendering in some pdf viewers..., but you can modify to obtain some good result in your document.

RESULT: TikzEdt viewer

RESULT: Firefox viewer ...{tikzpicture}[scale=1.5]
