Typical Process Flow of a Glazed Roof Tile Line

1. Purpose

A glazed roof-tile line turns color-coated or galvanized coil into stepped / glazed-look metal tiles. Unlike plain corrugated or trapezoid lines, it combines progressive roll forming with a hydraulic embossing press that stamps the tile steps, then cuts panels to ordered length.

2. Process sequence

1. Uncoiling — coil sized to the profile’s feed width
2. Guide feeding (leveling where fitted)
3. Multi-pass roll forming — creates the cross-section / ribs
4. Hydraulic step embossing — stamps the glazed tile pattern
5. Hydraulic cut-to-length
6. Exit / stacking

Many glazed-tile technical notes summarize the host path as uncoil → feed → form → hydraulic cut → exit; industry technology guides make the embossing station explicit as the step that separates glazed tile from plain roof sheet.

3. Three process phases

4. Forming speed vs working speed

Across many glazed-tile configurations:

• Forming speed (roller table): about 8–12 m/min
• Working speed (with emboss + cut cadence): about 3–5.5 m/min

Working speed is what usually limits plant output. Ask which figure a seller is quoting.

5. Cutter styles

After embossing, length cutting is commonly:

• Guide-post (four-post) cutter — aligned post-cut for formed tile
• Mid-plate / center-plate cutter — alternate packaging; power class can differ on the same formed-width family

Name the cutter style when comparing 1100-class or other codes.

6. Profile changeover

• Each formed-width code (828, 950, 1100, …) needs its own roll set
• Variants under the same number (828 main vs 828B, arc, trap) are not interchangeable without tooling change
• Match feed width, formed width, pitch, and peak to the drawing before freezing the line

7. Inquiry checklist

• Tile drawing (formed width, pitch, peak, step length)
• Feed / coil width
• Embossing + cutter style
• Both speed definitions
• Stacking and voltage preferences

8. Buyer FAQ

Why is a glazed-tile line slower than a trapezoid line?

Because of intermittent hydraulic embossing and stop-cut cycles — working speed reflects that cadence.

Can I skip embossing and still call it glazed tile?

The embossing press is what creates the stepped tile look. Without it, the product is a different roof-panel class.

Do cutter and roll set always travel together?

They should be matched to the same configuration. Changing only one can leave cut quality or geometry wrong.
