Who knows about gates with some sealer material at the main sections/ beams and whats used; ?  For decor or ? but its all of needing painting again  but these seams are not metal but a decor filler ???  No idea.  Anyone in Pattaya may know ? 

Are you looking for a shop/workplace that might be able to do maintenance, or are you asking what materials are used in your gate without posting a picture or anything so you can do it yourself?

 

Your post is very confusing to me.
