Currently all the infantry coming from Clockwork Goblin Miniatures are metal. The figures come on a long metal strip without metal bases like Flames Of War or Forged In Battle. The figures came with lots of detail and just a little bit of flash that can easily be removed. The figures look just right for power armor troopers, towering over normal infantry.
Here are a bunch of pictures of the Clockwork Goblin Miniatures (Heavy Infantry) that give you an idea of scale.
