Round Hole Perforated Tube

Round opening perforated sheet metal is the most widely used for making of
perforated pipes/tubes. The sheet metal is punched by a die to get its round
opening. The shape of the hole is determined by the shape of the die. For
perforating a round hole pattern, the die is pre-made into circular shape. Then
the sheets or plates are welded together to form a cylinder or tube.

Round hole opening has two patterns of staggered centers. 60°Degree Staggered
Centers round hole are the most popular of all pattern types because of their
inherent strength, their multitude of varied open areas ,and their attractive
appearance, An alternate to the standard patterns is 45°degree staggered
centers .Straight center round hole patterns are available in various sizes and
open areas, but they are the weakest of the round hole pattern.

The die’s diameter can vary from approximately twice the thickness of the
material being punched to over two inches.

Specifications:
The thickness of metal sheet:0.1-12mm
Hole types : round
Tube types: round, or square

Uses: Round hole perforated tubes are used for decorating, cage ventilation,
