Our perforated profiles cover galvanized punched steel series and HDPE perforated drainage pipe. Pre‑punched standard holes allow fast assembly without on‑site drilling. Steel versions adopt hot‑dip galvanized anti‑corrosion treatment for long‑term outdoor service. Custom hole shape, hole pitch, thickness, cutting length are available for different engineering requirements, widely used for solar mounting brackets, equipment frames, warehouse racking, building support, landfill drainage and civil engineering projects.

Main Features

• Pre‑fabricated punching holes, quick bolt‑on installation, save site labor cost

• Steel material: hot‑dip galvanized finish, excellent rust‑proof for outdoor environment

• Multiple hole options: round hole, square hole, slotted oblong hole

• Flexible custom: material grade, wall thickness, hole spacing, cutting length
