Shipping Details

MasterRib is Union Corrugating’s most popular metal roofing panel and is a leader in strength and durability. This versatile metal roofing panel features classic looks and is used in a wide range of roofing and sidewall applications, including residential, commercial, post-frame and agricultural. MasterRib is designed with extra wide ribs to increase strength and ease handling and installation. Another unique feature of the MasterRib panel is the extra large siphoning channel under the under-lap rib which provides extra leak resistance in extreme wind and rain conditions. MasterRib panels have our premium Siliconized Modified Polyester (SMP) paint system that provides the industry's best color stability, chalk resistance, fade resistance, gloss retention, stain resistance and scratch resistance 45 year paint warranty. The Galvalume coating on the panels provides rust resistance with a 25 year substrate rust warranty. Union's paint colors can reflect up to 70% of the sun's energy that can reduce attic temperatures and cooling costs.

Solid metal sheet

Would Recommend

Really liked this color. Could not find elsewhere. Just be aware it's not a full sheet wide. This worked fine for my application, but I imagine it might not be helpful in certain circumstances. Holds screws well and so far is corrosion resistant and easy to install.

Damaged

Would Not Recommend

Bought 3-12 foot pieces and one had a bad gash. I paid to have delivered but now I have to go back myself to replace with a good one.
