R-Panel metal roofs are the long-lasting and Beautiful stunning metal roofing option.They are easy to install and this course cuts down on labor,time,and disposal costs.These R panel roofs are available in many different colors.R-Panel/PBR-Panels are very popular for both local and commercial roofing systems.

R-Panel Metal Roof is built with 36-inch-wide interconnected metal panels.These metal roof types feature overlapping seams which limit water infiltration,but the exposed fasteners can be a point of weakness.  Cangzhou Zhongtuo Cold roll forming machine company is one of the leading R panel metal machine manufacturers in the R-Panel metal roof,and specialized in the design,manufacture the roll forming machines,and PRB panel roll forming machine.

Differences between R-Panels and PBR-Panels

Rib type roll forming machine PBR”Panel stands or Purlin Bearing Rib Panel is far better to the “R”panel for most roof and siding wall applications.These PBR-Panels include a larger overlap section (purlin bearing leg)between panels that give the metal roofing sheets more strength. R-Panels PBR Panels design for commercial,industrial,and steel frame building applications. The primary difference between the R-Panel and PBR-Panel is the Purlin-Bearing Leg on the PBR-Panel.This leg provides better support for roof applications.

PBR panel roll forming machine forming machine, mainly component as belows:

1. Hydraulic uncoiler

most customers choose 5 tons hydraulic decoiler, because hydraulic decoiler machine adopts hydraulic control core shaft expansion and shrinking, convenient, working fast and stable.

Driven control by electrical motor, high precision, good degree of automation, frequency converter control, the speed can be adjusted.

Decoiler	Work type	Passive
	Inner diameter	450-550 mm
	Loading capacity	5 tons
	Max coil width	1450 mm

• Feed device

Responsible for feeding metal coil into the forming machine

One set guiding roller, Steel plate welded platform to carry the sheet and feed into roll

forming system; Feeding width is adjustable with the handle wheels

• Main roll forming machine:

According to the design specifications of the roof panels, the molding mold will have different shapes and sizes, also different rollers station.

Rollers material normally use 45# steel and GCR15 steel, quenched.

Roll forming machine	Feeding device	the platform width is adjustable by hand wheel, have the bearing inside to protect the edge of the steel sheet.
	Rolling shaft	Shaft Material: 45# STEEL
		Shaft diameter: 80 mm
		Tampering treatment, prevent deformed and improve the hardness
	Roller	Roller material: 45# steel
		Chromed treatment (Cr thickness:0.05 mm), anti-corrosion,Increase hardness, ensure the precision and good abrasion performance
	Rolling station	18 stations
	Work speed	0-15 m/min
	Machine structure	Middle plate welded structure
	Machine basic frame	Hot rolled H-beam
		After the whole welding, vibration is used to weld the stress. After large-scale planer machining, the horizontality and rigidity of the frame are ensured.
