Products like the ones you are looking for are almost impossible to find. There are very few companies in the US that have the ability to manufacture them. Although we do not specialize in Beams we can make them for you.
We are a national, production, manufacturer of EPS (styrofoam) products. We currently catalog over 300 shapes, with 10 to 15 shapes available for immediate delivery. Products are provided in 8' lengths and are finished (layered with heavy duty netting and coated with acrylic modified cement in sand finish). Other shapes, finishes (including those for interior use), and lengths are available. Because the beams are a specialty item, we would need a couple weeks lead time to produce the product, plus time to ship it.
Please visit us online at quantuviseps.com. An online catalog is available on the brochure tab. If you are unable to download the brochure, please contact our sales department at quantuviseps.com and we will either email one to your or send you a hard copy (your choice) or you can contact via email at firstname.lastname@example.org.
Shipping is available nationwide.
If you have an idea of size and shape, etc. send an email with the info and a drawing of the shape, if available. If you are unsure, please see our catalog for shape ideas. Include your location and we will provide product pricing (including shipping).
