CL Aluminum's flashing products are built to do one thing exceptionally well: keep water out and structures protected, whether you're installing it, manufacturing with it, or stocking it for resale.. Step flashing seals roof-to-wall joints, and Z-bar flashing shields horizontal seams on sheds, so contractors and shed manufacturers get code-compliant, leak-preventing protection at every critical joint, not just the roof edge.

Each piece is precision-bent for a consistent fit, so it goes on fast and seals tight without field-adjusting. Whether the job is a home, a shed, or a commercial build, the flashing line gives your crew professional-grade protection and one less thing to worry about on inspection day.

Why Contractors and Shed Manufacturers Choose CL Aluminum

  • American-made, at our own facility. Every piece is manufactured in-house, so you're getting consistent bends and dependable lead times instead of guessing what shows up on the truck.
  • Multiple sizes and gauges for any project. Step flashing comes in 3"x3"x8" and 4"x4"x8" sizes, in both 0.015 and 0.019 gauge, so you can match the joint you're sealing without over- or under-building it. Step flashing ships 500 pieces to a box, ready for high-volume jobs and production runs.
  • Color options that match the job. Step flashing comes in white, black, and brown to work with common shingle and siding colors, and Z-bar is available in 2 color options for a clean match on shed and building exteriors.
  • Factory-direct pricing, no middleman markup. Buying straight from the manufacturer means better pricing whether you're ordering for contractor jobs, production runs, or wholesale resale. Bulk orders can save up to 20%.
  • Code-compliant and precision-bent for a perfect fit. Every piece is bent to a consistent profile, so it fits right the first time and holds up to inspection.
  • Dedicated service from order to shipment. You get the same attention whether you're a small contractor placing a first order or a shed manufacturer with a standing account.
