Metallics
Metallics is a Fabric and NeoForge decoration mod that adds metal-style building blocks for copper, along with framed glass, mesh blocks, buttons and pressure plates.
What it does
Metallics starts with a base copper set and extends it to a broad range of metal-themed building blocks. Decor blocks are made for each metal type, and the author plans to extend the same treatment to other vanilla metals and to modded ones later. Framed glass, mesh blocks, doors and fences sit alongside the solid metal blocks, and additional flame colors and a blue iron set with a darker tone are included to match the vanilla lantern look.
Addon content covers industrial, steampunk and magic themes. Metallics works with Integration Addons, Create, Tech Reborn and Mythic Metals. Architectury API is required on both loaders, so it must be installed next to the mod. Servers that run it need every player to install it too. The code is released under the MIT License and is open source, with a public source code repository and issue tracker. Files are published for Fabric and NeoForge, for game versions 1.21.10 – 1.21.11.

What the author says
Adds a large range of metallic building blocks for every vanilla metal type(modded ones planned). I love copper building blocks and wanted to give every metal in the game that treatment. As well as adding to the base copper set.
