The Angels of Iron's Chapter colours are silver with blue shoulder guards marked out with gold trim. The Aquila or Imperialis on the chest is also golden. The Angels of Iron are known to display their loyalty and dedication to the Imperium of Man by decorating their Power Armour with numerous Purity Seals and intricate scroll-work carefully inscribed upon the Ceramite surface of their blessed battle plate. The white squad specialty symbol (Tactical, Assault, Devastator or Veteran) is indicated on the right shoulder guard. The black Roman numeral stenciled on the center of the squad specialty symbol indicates company number.
The Angels of Iron's Chapter badge consists of two golden keys saltire (crossed) on a field of light blue. The crossed keys of gold symbolise the keys to the Eternal Kingdom where mortals serve the Emperor beyond death, and the Emperor's authority to bind and loose souls to enter this realm.
