Steatherm is a company located in Spain, working on the manufacture inertia radiators with steatite ( a type of metamorphic rock ) core, they export these radiators to several companies in France and Belgium licensed for sale and installation of all construction products.
One of the most important characteristics of this radiator is that it contains steatite rock so it can maintain the temperature for a long time after its disconnection from electricity, therefore it is economical and preserves energy, for that reason, when I was working for this brand logo, I took in consideration the importance of the rock and made it the focal point of my design to highlight this component to clarify the vision and the way this product works.
As shown below I based the drawing of this brandmark on two perspective points, to give it a three-dimensional vision.
