update possible to glue a2in x 1in Thin piece of stainless steel as thin as a name tag to a piece of Alumawood if yes what glue would i use?

this is a update question cuz photo it give a batter idea. 

OK so I know the Alumawood has built-in texture to it. but I was hoping that the glue could overcome the texture and handle the heat as well in summer time. again this is to hung a shop light in the ceiling of the Alumawood ceiling.and no hole can be made this is a flat pan roof so if i can glue the stainless steel plate sheet witch be thick like a name tag you were at work like a market or clothing store and so on then to hold the shop light would be 2 brackets flat one. and 2 magnets that has a 95 lbs Pull Capacity. put 2 on  Each sides ( o )==( o )   ( o )==( o ) then a hook that will bolt to the bracket in the middle of it photo show it 99% of it built in photo not in real life yet and attach to the stainless steel piece and the plate glue to the Alumawood to show u so u see what i mean if i can not glue a plate then i have other idea but this idea would cost way less to do. & cuz the Alumawood has texture i thought maybe tracing the plat where it will goes then put some epoxy glue in the square area let it dry & then sand it to make it flat & then score it like ### & then glue the plate in. epoxy glue works better when it has grooves to get intoother idea that would cost way more would be attach 2 wood beams across like this ║      ║ then install the light to the beams. the beams will attach to wall only & not ceiling but be flush to the ceiling across to other side to the beam that is Alumawood cross beam
