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.

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.
