Fabrication Services

We’re Here to Help
Many of our customers are buying FRP products for the first time. They have many questions about the type of grating they need, how strong it should be, and how to order it.

Call us anytime. We are happy to discuss your application and offer suggestions on how to complete your project. Often molded grating with non-slip mesh is the best option and sometimes stronger, pultruded  grating is better suited for longer spans. We will explain the pros and cons of each option and provide a competitive price quote within 24 hours.  We look forward to hearing from you.
