Description :
Mega Rib Industrial Profile Metal Roofing

 

 

 

Product Description

The Mega Rib is another premium profile roll formed from high-strength steel. This profile is the economic alternative to CL 660, except that it has to be installed using screws. The high ribs and wide pans of the Mega Rib ensure excellent rain water flow capacity and good spanning capability. Mega Rib comes in two different profiles; Mega Rib 30 and Mega Rib 35. Mega Rib 30 has a rib height of 30mm and an effective width of 750mm. Mega Rib 35 has a rib height of 35mm and an effective width of 723mm. Both are designed for a minimum roof pitch of 2 degrees.

 

Applications

When installed properly according to manufacturer instructions, this profile guarantees a watertight roof cover. Mega Rib is versatile and is equally suited for use as cladding and fascia.

 

Materials Available

  • Clean Colorbond® Steel
