Dear Khun Adisai,
I have reviewed the proposed material and have the following comments.
The detail referenced shows a 75 x 50 x 4 galvanised mild steel wire mesh. However the proposed material is 100 x 100 x 4 mesh and the product references are to cold drawn steel wire and with no reference to the material being galvanised as required by the detail.
Can you advise why you have adopted 100 x 100 instead of the 75 x 50 spacing and can you confirm that the mesh and its support framing will be hot dip galvanised after fabrication as required by OCS Clause 7.17 and that the galvanizing will comply with the requirements of BS 729..
Regards,
