Metal Box Profile Roofing Sheet Rolling Machine

Box profile roofing sheets are currently our most popular product as they offer a modern alternative to the older corrugated style at a very competitive price. In the market, each box profile roofing sheets price around 6.5USD/ meter.

What Box Profile Roofing Sheets?

Box Profile Roofing Sheets consist of six profiles and five valleys where the water runs. The profiles are 32mm deep and at 200mm centres. For extra support and stability, two extra ribs can be roll formed into every valley of the sheet.

GBR roofers manufacture Box Profile Roofing Sheets from coil of flat coated steel which are processed through a roll forming machine. The machine is able to form any length and thickness of sheets.

Box profile is a modern alternative to corrugated metal sheets, which effective cover width is 1000mm. It also has a capillary groove down one edge which eliminates the need for using sealing strips and is proof.

Metal Box Profile Roofing Sheet Rolling Machine

Automatic Hydraulic Uncoiler

Hydraulic uncoiler is for holding and driving the steel coil. The uncoiler allows for a quick change of steel coli with minimal manual labor. The uncoiler is powered with a feedback system that ensures the roll former is not required to turn the coil. And the uncoiler will turn as required to reduce the potential for over coiling.
