Unfortunately, crystalline structures are, as you have experienced, not the easiest thing to simulate using gromac's system building tools. Typically, people working on MOFs, clays, general polymers, and other non-biological systems use something like LAMMPS (or DL_Poly like you have already noted). That being said, it isn't impossible to use gromacs for these types of systems, it just takes a bit of time.
One tool that can be useful for these types of systems with gromacs, however, is the x2top tool. It is far from perfect, but it can get you started in the right direction.

Subject: [gmx-users] Usage of GROMACS
is GROMACS meant to be used for simulations of crystaline structures
(Metal Organic Frameworks, porous materials, minerals, ...)? Almost
every paper working on MD simulations with said structures use DL_Poly
or other software. So my question would be is there a community that
uses GROMACS to simulate crystaline structures? Porting .cif files to
pdb and then trying to run pdb2gmx with writing a .rtp file is very time
