Galvanized Steel Storm Collar Flashing Cone

1. Effective Waterproofing: Rain collar roof flashing is installed between the roof flange (flashing) and the pipe, creating a physical barrier that diverts rainwater and snow away from the base of the pipe, preventing leakage.

2. Weather-Resistant and Corrosion-Resistant: Rain collar roof flashing is made of high-quality galvanized steel with a zinc coating, which resists rust and extends its service life in outdoor environments. For applications requiring stronger corrosion protection, hot-dip galvanizing (thicker and more corrosion-resistant) is available; for those with high aesthetic requirements, electroplating (a more uniform surface) is also available.

3. Easy Installation: Rain collar roof flashing is typically designed with a snap-on or adjustable structure, which fits snugly within the roof's tapered flange during installation. Gaps can be sealed with silicone or a specialized sealant to ensure waterproofing.

4. Customizable: Pipe diameter, cone height, material thickness (gauge), opening type, perforation, and logo printing can all be customized according to drawings or samples.

1. Cutting/Cutting: Typically, galvanized steel sheets are first CNC-cut or laser-cut (to ensure dimensional accuracy and neat edges) to produce blanks with a cone and flat flange.

2. Forming: Depending on the design, the flat sheet is formed into the cone and appropriate flange shape using bending (press brake), rolling/forming, or die-drawing. For long, batch-produced parts, hemming or roll-forming processes may also be used.

3. Joining: The cone and flange are typically secured using spot welding/spot seam welding or rivets. Reinforcement ribs are added as necessary to prevent deformation. The weld seams are often sealed with silicone sealant.

4. Surface Treatment (Galvanizing): The base material is galvanized steel, and the zinc coating remains intact before shipment. Hot-dip galvanizing can be applied to achieve a thicker protective layer, or a combination of electrogalvanizing/galvanizing followed by spray coating can be used to balance appearance and corrosion resistance, depending on customer requirements.

1. Pipe Diameter/Inner Diameter: Customizable based on the flue or exhaust pipe outer diameter (e.g., 2", 4", 6", 8", and other standard or custom sizes);

2. Steel Plate Thickness: Commonly 0.6mm–1.5mm (adjustable based on load-bearing, strength, and cost);

3. Surface Finish: Hot-dip galvanized/electrogalvanized/galvanized and then painted;

4. Finishing: Available with pre-drilled holes, grooves, hem reinforcement, printing, or marking.

Suitable for waterproofing roof access areas, flues, exhaust pipes, vents, boiler/water heater exhaust, and other structures penetrating roofs or walls. It is a basic and essential waterproofing accessory.

1. We use certified, high-quality galvanized materials and recommend the appropriate galvanizing method based on the intended use (a thicker hot-dip galvanizing coating is preferred for exposed, coastal, or humid environments to extend life). Choose us as the manufacturer of Galvanized Steel Storm Collar Flashing Cones.

2. High Precision: We combine laser cutting with precision bending/rolling processes, with welding and sealing performed according to installation requirements, ensuring stable and reliable factory quality.

3. Supporting Samples and Customization: We offer fast proofing, custom-designed production, and batch supply. Dimensions and appearance can be adjusted to meet customer requirements.
