This item ships rolled up in a box with the "diamond" side on the outside of the coil. Once the coil is removed from the box, it will naturally uncoil itself. However some residual curve may remain – this is normal and will naturally flatten out when installed.

I want to congratulate the entire team at diamondLife Gear on running a great business. I found the website easy to navigate with accurate information regarding the product (description, dimensions, etc.) and honest timelines concerning manufacturing and shipment of the product. There was excellent communication from the service department throughout the entire process. Emails were sent with confirmation of the order, receipt of purchase, shipping confirmation, and final follow up. When the product arrived it was packaged in a way to minimize the possibility of any shipping damage. My piece arrived in excellent condition and was the exact specs that were listed on the website when I ordered. Great product. The piece I ordered was used to complete a handicap ramp that I built for my grandmother. It made an excellent transition piece from the end of the ramp to the ground. She is easily able to navigate her way on and off the ramp in both her wheelchair and using her walker. Your product has exceeded my expectations! Thank you for selling a great product and providing excellent customer service!

What metal thickness should I use?
Determining the appropriate material thickness for a given loading condition is an engineering question that we cannot answer. Every material, no matter how thick, will have some deflection when loaded, whether that deflection amount is imperceptible or not. The amount of deflection is dependent on the material thickness, material’s physical properties and the largest unsupported span. There may be some online calculator tools which attempt to predict this amount of deflection. Generally speaking, 0.045" and 0.063" are used as "veneers" and 0.125" and 0.250" are used in structural applications.
