We build and shipped some custom size shoji doors made in “sugi” pine wood. sizes are 1238mm x H 2200 for one door and 950mm x H 2200 for another opening. (normal shojis are in the range of 900mm for the width and 1800-2000mm for the height.)
We also provided overhead rail floor rails and jambs made in hinoki gluelam (it is safer than solid wood as it does not warp or bend)
We supplied the shoji paper and glue/spackle separately as paper is easily damaged by humidity during the ocean freight. Inside the container the temperature tends to be very high, and paper will stretch and wrinkle if it is already attached on the shoji frame.
