1. Clean the wall to ensure that the wall is smooth, dry, and free of oil. 2. Calculate the plan for setting the square wood, layout the lines, and then fix the stainless steel plate on the wall with stainless steel expansion bolts, and then connect the 90cm long 50X40 galvanized steel pipe to the stainless steel plate by welding. 3. Cut one end of the 90cm-long 100X50 square wood at an oblique angle of 45 degrees and put it in the galvanized steel pipe, then plug the wooden square into the vertical square wood (bevel at 45 degrees at both ends), and plated with a cross flat head. Zinc self-tapping screws fix the dark side of the two pieces of square wood. 4. Take the same method to seal the other port. 5. Clean the surface stains after the square wood paving is completed.
