Punched Slotted Tube

Slotted metal tubes are fabricated from perforated sheets with slot holes/openings punched with the pre-made dies or models. Then the sheets are welded to form a cylinder or pipe. The pattern of the opening is determined by the shape of the die. In perforating and slotting, die making accounts greatly. Hengda has first-class digital controlled CNC punching press and an extensive range of dies to provide stainless steel and aluminum slotted perforated tubing with high opening precisions.

Punching Dies:
The die for punching slotted pipe can vary in the width, length, patterns to meet customers’ requirements. The ends of the slot can be round or square or custom made.
Metal Materials:
The materials most frequently used to production these metal pipes and tubes are stainless steel AISI 304-316, stainless steel, aluminium alloy and any other material suitable for perforation and slotting.

About the Slotted Hole Patterns:
Slotted Holes are elongated holes with round or square ends. They are available from stock in either a side staggered or a straight line pattern in plain steel. Others gauges, hole sizes, patterns and materials are available by special order.

Punched sheets and pipes offer more flexibility and rigidity to arrange store display, giving a fresh and elegant look with flexibility in quality.
