The metal panel systems distributed by 3R Tiles inc. are available with or without stiffening ribs reinforcement. In both cases, some oil canning may occur on the surface. This is primarily related to the physical constraints inherent to the raw material, steel or aluminum. Oil canning can also be aggravated by thermal expansion, poor installation and uneven leveling of the supporting surface.

During factory manufacturing of metal panels distributed by 3R Tiles inc., the material is systematically rectified by in-line leveling equipment right before the profile forming process. Subsequent oil canning of the metal surface is essentially an aesthetic consideration and does not result from a flaw in the panel manufacturing process.

To reduce the risk of oil canning in metal panels, 3R Tiles inc. recommends the following precautions:

• Transport, handle and store the panels in accordance with the regulations set out in the 3R Tiles inc. Job Site Handling Manual
• Level the metal panels supporting surface
• Avoid applying too much pressure to the joint between panels during installation
• Provide expansion space for panels where the trim systems are connected
• Limit the length of metal panels to 20 feet as much as possible (for some panel models, connecting plates are available)
• Fasten the screws perpendicular to the panel surface and avoid excessive screw insertion
• Promote the use of ribs and panel patterns with uneven surfaces
