Metal textures should be a part of any designer’s toolbox. There are various metallic textures thanks to the way metal can be manipulated in many shapes and sizes. You can get a grunge texture from a rusted metal or a sleek texture from a brushed metal stock photo.
What I like about these metal textures is that you can use them also as backgrounds on websites and they give that steampunk look which is a trend nowadays.
There are 72 metal textures in this article. They’re not tileable ones but can be done with a little effort in Photoshop. However, some of them are humungous having more than 3000px width. I’m sure you can find a good purpose for those.
Remember to check their license and use them accordingly.
