Technical Details Up and Over

The steel frame is a galvanised box section steel and prefinished in a powderocat colour - white or brown in most cases.
The dimensions below show the requirements for installation with a small tolerance allowed.
The ordering size references for ordering are shown below and refer to the inside of the sub frame NOT including the sub frame sizes.
