What Is a Ridge Cap and a Ridge Making Machine?
A ridge cap (also called ridge roll, hip cap, or ridge tile) is a metal profile used to cover the peak (ridge) of a sloped roof where two roof planes meet. It provides a weather‑tight seal and a finished appearance. Ridge caps are essential for any metal roofing system.
A ridge making machine is a roll forming machine specifically designed to produce ridge caps, hip tiles, and related roof flashing profiles. It works by forming a flat steel coil into an angled or curved shape that fits over the roof ridge.
Why is the ridge cap important?
- Prevents water infiltration at the highest point of the roof
- Provides a professional, finished look
- Protects the ridge from wind and debris
- Completes the roofing system (ridge cap is sold alongside roof sheets)
Common ridge cap shapes:
- V‑shape (angled) – simple folded angle, most common
- Curved / half‑round – decorative, for traditional or glazed tile roofs
- Trapezoidal – matches trapezoidal roof sheet profiles
- Corrugated – matches corrugated roof sheets
Typical sizes:
- Width (flat before forming): 200mm – 600mm (unfolded)
- Finished coverage: 150mm – 500mm per side (depending on roof pitch)
- Length: cut to customer order (usually 1.8m – 3m)

Production Line Flow
Small Decoiler → Feeding → Roll Forming (8–14 stations) → Length Setting → Hydraulic Cutting → Output Table
Step‑by‑step description:
- Decoiler – A small coil (or slit strip) of steel is loaded and unwinds.
- Feeding – The strip enters the roll forming stations.
- Roll forming – The strip passes through 8–14 roller pairs that gradually bend the flat strip into the ridge cap shape (V‑angle or curve).
- Length setting – Operator sets desired length on PLC or simple counter.
- Cutting – Hydraulic shear cuts the formed ridge cap to exact length.
- Output – Finished ridge caps are collected on the output table.
Key Machine Components
| Component | Function |
|---|---|
| Decoiler (Uncoiler) | Holds and unwinds the steel coil (manual or hydraulic type, typically 3–5 ton capacity). Feeds the strip into the production line. |
| Feeding & Guiding Device | Aligns the strip to prevent sidetracking; ensures straight entry into the forming section. |
| Main Roll Forming System | The core forming section where the flat strip passes through 10–18 progressive roller stations. Each station gradually bends the metal into the final ridge cap profile. |
| Pressing Device (Optional) | Hydraulic pressing unit for embossing decorative patterns, notching, or adding reinforcement beads. |
| Hydraulic Cutting Device | Guillotine-type hydraulic shear cuts the continuous profile to preset length. Burr-free cutting with Cr12Mov blades. |
| Hydraulic Pump Station | Provides hydraulic power for the cutting system (and optional pressing unit). |
| PLC Control Cabinet | Central control unit with touch screen HMI. Stores recipes, monitors production, and displays fault diagnosis. |
| Run‑out Table | Supports finished ridge caps after cutting; standard length 3–6 meters |
Applications – Where Ridge Caps Are Used
Why ridge caps are essential:
- 它们覆盖了在屋顶顶部相遇的两个屋顶板之间的间隙
- 它们提供防水密封，防止雨、雪和碎片
- 它们为屋顶的接缝和角度增添了美学价值
- 它们通过防止脆弱接缝处进水来保护屋顶系统的结构完整性
Frequently Asked Questions (FAQ)
What is the difference between a ridge cap machine and a roof sheet machine?
A roof sheet roll forming machine produces large panels for the main roof surface (corrugated, trapezoidal, IBR, etc.). A ridge cap roll forming machine produces small finishing components (ridge caps, flashing) used to cover the joints at the roof peak. The two are complementary—ridge caps complete and seal the roofing system where roof sheets meet at the apex.
What ridge cap shapes can the machine produce?
Standard V‑shaped and W‑shaped ridge caps for general residential/commercial use; curved/arched ridge caps with a semicircular dome for high-end residential and architectural applications; hip and valley ridge caps for complex roof geometries where two roof planes meet; custom ridge cap profiles based on your drawings and sample
What raw materials does the machine accept?
The machine processes PPGI (pre-painted galvanized steel), GI (galvanized steel), aluminum, and standard color steel coils.
What material thickness can it process?
Standard processing range is 0.3–0.8 mm. Custom configurations are available for thickness up to 1.2 mm for heavy-duty applications.
