At Professional Grade Aluminum we take pride in our work and make sure that we supply you with only the best and top quality products and services. We work with proven and trusted vendors who provide us with top notch components that are used to assemble our products. We are proud to offer our 5 year limited warranty so that you can feel confident that you are getting a piece of mind with your purchase for many years to come. If you ever have any questions or require service, please feel free to reach out to our technical department and we will do our best to have the issue resolved right away.
While all our products are covered by our standard products warranty, sometimes a project specific warranty is needed. For that purpose we have designed a Project Specific Warranty Certificate that gets filled out and distributed to a specific project and specifies exactly what is covered on a specific project and the duration of the warranty period. This needs to be done with the help of our customer service in order to make sure that the certificate is filled out correctly and is registered in our database. Lets us know if you have any questions or need help setting this up for your project.
