Glazed Roof Tile Roll Forming Lines: Overview and Profile Families

1. Definition

A glazed roof tile roll forming line (琉璃瓦成型线) produces stepped / glazed-look metal roof tiles from color-coated or galvanized coil. The finished sheet mimics traditional clay-tile rhythm while remaining a cold-formed metal product.

Unlike plain corrugated or trapezoidal roof sheets, glazed-tile lines combine progressive roll forming with a hydraulic step-press that stamps the tile pattern along the length, then cut the panel to ordered length. Each marketed formed-width code — 828, 950, 1100, and related families — is a separate machine configuration with its own feed width, pitch, peak, stand count, and power package.

2. Process route

1. Uncoiling
2. Guide feeding (and leveling where fitted)
3. Roll forming of longitudinal ribs / outline
4. Hydraulic pressing / embossing of tile steps
5. Hydraulic cut-to-length
6. Exit table or stacking

Industry technology guides describe the same three core blocks — forming, intermittent stamping, and post-cut — which is why glazed-tile output is usually slower than continuous single-skin roofing lines.

3. Forming speed vs working speed

Across many glazed-tile configurations, two speed figures appear:

• Forming speed — about 8–12 m/min for the roller table on many mid-size profiles
• Working speed — about 3–5.5 m/min, reflecting stop-and-press embossing plus cut

Public catalogs often advertise working / production rates in a similar low-single-digit to mid-single-digit m/min class for embossed tile. Always ask which number a seller is quoting.

4. Profile families

Other marketed codes (780, 840, 1000, and so on) follow the same rule: one code ≠ one universal BOM. See also the dedicated entry on feed width vs formed width.

5. Shared thickness and speed bands

Many glazed-tile profile documents share these orientation bands — useful for planning, not for copying one machine’s kW onto another:

Shaft diameter and stand count still change by code (for example φ70 with ~11 stands on one 828 main file vs φ80 with ~11 stands on 1100 guide-post). Never cross-fill those details.

6. Cutter styles

Two cutter packages appear frequently on glazed-tile lines:

• Guide-post (four-post) cutter — aligned post-cut for formed tile profiles
• Mid-plate cutter — alternate packaging; on the 1100 family, main-motor class can differ from the guide-post sibling

Name the cutter style on the inquiry. Do not assume every “1100” quote uses the same power sheet.

7. Ridge and accessories

Ridge caps, hips, and matching flashings for glazed roofs are normally produced on ridge / accessory equipment, not assumed inside every tile-former proposal. Plan accessory tooling separately when the roof package needs them.

8. How to select

1. Start from the roof tile drawing and target formed covering width.
2. Match the machine code (828 / 950 / 1100 / …) and any variant (arc, bamboo, trap, B).
3. Confirm feed width for coil purchasing.
4. Confirm cutter style, speed definitions, and ridge needs.
5. Refuse “one glazed-tile machine fits all codes” answers.

9. Buyer FAQ

Is a glazed-tile line the same as a corrugated roof line?

No. Glazed-tile lines add intermittent step pressing and usually run at lower working speeds.

Can I copy 828 power onto a 1100 machine?

No. Each code has its own shaft, stand count, and power package.

What thickness is typical?

About 0.3–0.8 mm on many profile documents; confirm grade and coating for the project climate.

Where do ridge caps come from?

From ridge / accessory equipment proposals — not automatically from the tile former rating sheet.
