Material Tensile Strength	Max 500MPa
Material Yield Strength	Max 235MPa
Coil OD	1000mm to 1800mm
Coil ID	508mm&610mm (customer order)
Coil Weight	Max 3000 kg
Strip Width	Min 40mm, Max120mm
Strip Thickness	Min0.5 Max 2.0 mm

▪ Production Range

Type of production	▪Round Tubes ▪Square and Rectangular Hollow Sections
Round Tube OD	Min 12mm, Max 32mm
Round Tube Thickness	Min 0.5mm, Max 2.0mm
Square Hollow Section	Min 10x10mm, Max 30x30mm
Rectangular Hollow Section	Min10x20mm, Max 20x40mm
Square and rectangle Tube Thickness	Min 0.5mm, Max 2.0mm
Tube Cut Length	Min 5 meter, Max 7 meter

▪ Line Specification

Line speed	Max 90m/min Min 30m/min
