On 3/10/2026 Caleb Ritter (Critter) had this to say:
I have been running my own small welding Business (FutureRustic Fab LLC) out of Pagosa springs for almost a year now. Cal Steel has been one of my main suppliers of everything metal this whole time. They are very responsive, respectful, and professional. I have directly delt with Mitch more than anyone else and he is such a stand up dude and more of a friend now. Everyone else has always been so kind and helpful. I would highly recommend them for the welding, metal and delivery prices, great people, overall great business, and professionalism. I will say that nobody is perfect but when there has been mistakes they went out of there way to help remedy what ever the problem is and come to a professional collusion. I love you guys and thank you for the upstanding service and working together to make our costumers lives better.
