Glazed Tile Roll Forming Machine

A glazed tile roll forming machine turns flat coated coil into steel roof tiles that read as fired clay from the street. The profile is a step tile, closed by a hydraulic die into repeating courses. The finish is a high gloss paint that imitates ceramic glaze, which is where the name comes from.

Short answer: a glazed tile roll forming machine forms 0.30 to 0.80 mm prepainted or Al-Zn coated steel into tiles with a 250 to 350 mm step and 900 to 1150 mm cover, at 4 to 8 m/min. A standard build uses 16 forming stations, a 7.5 kW main motor and a four post punch and cut unit, and makes about 2,300 m of tile per eight hour shift.

Two numbers decide the build, and neither is in the roof photo a buyer usually sends. The step length sets the die, the cover width sets the coil. This page works through both, then the coil, the coating and the site work.

What the Machine Produces

Output from a glazed tile roll forming machine looks like a row of clay tiles. Each course is a raised step with a rounded nose. Ribs between courses cover the side lap, and the bottom edge of one sheet sits over the top edge of the sheet below it, so the step hides the joint.

A common build makes a 320 mm step across a 1000 mm cover. At 0.45 mm steel that sheet weighs about 3.8 kg per square metre. One square metre takes 3.1 tile courses, and one linear metre covers one square metre of roof. Those ratios decide cost per square metre, not tonnage.

Glazed is a finish claim, not a shape claim. A step tile with matte polyester is sold as step tile. The same profile with a 40 gloss clear top coat is sold as glazed. Buyers in Nigeria, Kenya, the Philippines and Indonesia ask for glazed because the shine sells the roof. Buyers in Russia and Eastern Europe ask for step tile because the section matters more. Both come off the same tooling, and the difference sits in the coil order.

Inside the Line, From Coil to Stacked Tile

Eight modules make up a glazed tile roll forming machine. Coil goes in at one end, stacked tiles come out at the other, and nothing is handled by hand once the batch is set.

Decoiler, 5 t hydraulic as standard, holds the coil and pays it out under back tension.
Feeding and guiding, a pair of side rolls that keep the strip on centre.
Pre cutter, which squares the leading edge so the step die always indexes from a true datum.
Forming mill, 14 to 20 stands that build the ribs and the tile channel in stages.
Step press, a hydraulic die that stamps the tile course into the moving strip.
Punching and cutting, one four post body that punches holes and shears the sheet to length.
Hydraulic station, 11 kW with an accumulator so press and shear hold pressure during a cut.
Runout table or stacker, which catches the tile without scuffing the face.

The step press separates a glazed tile roll forming machine from a plain roofing line. Rolls bend a rib, but they cannot close a 14 mm step with a rounded nose in one pass. A hydraulic die does it in one hit while the strip is stationary. That pause is why the line is quoted at 4 to 8 m/min, against 15 m/min for trapezoidal sheet.

Floor sequence runs uncoiling, feeding, forming, step pressing, punching, cutting, collecting. Length is 18 to 22 m.

Profile and Coil Reference

Four step tile families cover most orders for a glazed tile roll forming machine. The family decides the die, the coil width decides the cover.

Profile family	Step length	Cover width	Minimum pitch	Where it sells
Classic step tile	320 mm	1000 mm	15 degrees	Nigeria, Ghana, Kenya, Philippines
Narrow step tile	300 mm	900 mm	15 degrees	Indonesia, Malaysia, Vietnam
Spanish S tile	300 to 350 mm	1050 to 1150 mm	14 degrees	Middle East, North Africa
Deep step tile	350 mm	1000 mm	12 degrees	Russia, Kazakhstan, Eastern Europe

Cover width is always smaller than coil width, because the side rib and lap eat the difference. A 1250 mm coil feeding a 1000 mm cover loses 20 percent. That number belongs in a price comparison, since a cheap glazed tile roll forming machine with a wide loss is expensive per square metre.

Coil width	Typical cover width	Material loss	Tiles per square metre at 320 mm step
1000 mm	820 mm	18 percent	3.8
1200 mm	1000 mm	17 percent	3.1
1250 mm	1050 mm	16 percent	3.0
1250 mm	1150 mm	8 percent	2.7

Tiles per square metre: divide one square metre by cover width times step length in metres. At 1.05 m cover and 0.32 m step that gives 2.98.

Two rows matter before an order. Shaft diameter caps strip width and the step depth the mill holds square. Station count sets how gradual the rib forms, and a deep step on thin coil needs the extra stands to avoid stretch marks.

Coil and Coating Choice

On a glazed tile roll forming machine the coil order decides how long the roof lasts. Three layers matter, and each is worth writing into the order.

Steel grade

Deep steps want ductility. DX51D+AZ and S250GD to S280GD form a 14 mm step without cracking at the nose. G550 resists wind load but cracks at a deep step, so it belongs on trapezoidal and corrugated sheet. When a job needs strength and a deep step together, drop the step to 10 mm and raise thickness instead.

Metallic coating

AZ150 is the export default for a glazed tile roll forming machine: 150 g per square metre total, both sides, of a 55 percent aluminium, 43.4 percent zinc, 1.6 percent silicon alloy under EN 10346 and ASTM A792. That alloy keeps a coastal roof alive past 20 years. AZ100 suits inland dry markets. The Galvanizeit corrosion data is the reference we hand to buyers who ask why not plain zinc.

A glazed tile roll forming machine cannot protect a bad edge. A sheared edge on 0.35 mm sheet exposes bare steel, so the cut face is where rust starts. Keep the cut trimmed by the line rather than by hand.

Paint system

Polyester at 20 to 25 microns is the usual finish on a glazed tile roll forming machine, with a 30 to 40 gloss unit top coat. SMP holds colour better in strong sun. PVDF at 25 to 27 microns suits a 20 year colour warranty and roofs within 1 km of the sea.

One limit catches buyers every month. Stone coated coil cannot be roll formed, because granules crack at the step and shed at the rib. Stone coating is applied after forming by a specialist coater, so the glazed tile roll forming machine supplies bare formed tile and the coater adds the finish. Prepainted and PVDF coil run without change.

Output, Speed and Manpower

Speed on a glazed tile roll forming machine is not a single number. The mill forms at one rate and pauses for the step press, so the quoted figure includes both.

Line speed	Metres per 8 hour shift	Roof area at 1.05 m cover	Tiles per shift at 320 mm step
4 m/min	1,530	1,600 sqm	4,800
6 m/min	2,300	2,415 sqm	7,250
8 m/min	3,060	3,215 sqm	9,560

Those figures assume 80 percent efficiency. A 5 t coil of 1.2 m by 0.45 mm steel runs about 1,180 m, so a 6 m/min glazed tile roll forming machine changes coil twice a shift. Two operators run it.

Short batches change the maths. A 20 sheet order on a glazed tile roll forming machine means 20 step cycles and 20 cuts, so it spends more time indexing than forming. Servo feed helps, and so does a die that swaps without re shimming.

Which Tile Machine Fits the Job

A glazed tile roll forming machine sits at the decorative end of the tile family, and four pages on this site overlap. The difference is the section, not the price.

Machine	Section	Best for
Glazed tile machine	Step tile with 250 to 350 mm courses	Residential roofs that must look like clay tile
Metal roof tile machine	Shingle and tile look, shallow relief	Reroofing, lightweight structures
Steel tile profile machine	Custom profile, up to 30 mm depth	Buyers with their own drawing
Monterey V1100	Russian step tile with condensate grooves	Russia, Kazakhstan, cold climate roofs

Start with the metal sheet roll forming machine index if the section for a glazed tile roll forming machine is still open. For a shingle look, read the metal roof tile roll forming machine page. For a drawing already in hand, the steel tile profile page covers custom tooling. For the Russian market, go to Monterey V1100.

A glazed tile roll forming machine also pairs with a ridge cap line, because every tile roof needs caps that match the tile colour and pitch. The roof ridge cap roll forming machine page covers that. Buyers running sheets and tiles together sometimes add a double layer roll forming machine for the sheet side and keep the tile line separate.

Roof Interface: Pitch, Overlap and Fixing

A tile from a glazed tile roll forming machine still leaks if the detailing is wrong. Minimum pitch is 15 degrees for a 320 mm step and 12 degrees for a deep step. Below that, capillary action pulls water up the lap in driving rain.

Side lap runs one full rib, which the roll set builds in. End lap runs one step plus 100 mm, so the nose of the upper tile sits over the flat of the lower one. Fixings go at the crest of the rib, never in the channel, each with a sealing washer. The NRCA steep slope guidance follows the same rules.

Order caps from the same coil batch. A glazed tile field with a plain galvanized ridge looks unfinished, and a curved roof needs the curving option ordered with the machine.

Shipping, Installation and Commissioning

A 16 station glazed tile roll forming machine with hydraulic decoiler loads into one 40 foot high cube plus one 20 foot container. The mill body ships in two or three bolted sections, with numbered wiring looms and oiled machined faces.

On site the order is fixed. Set the floor pads, level the mill to 0.5 mm over its length, bolt the sections, connect hoses and power. Fill the hydraulic station with 46 grade oil, run the pump unloaded for ten minutes, then check for leaks.

Commissioning takes 7 to 10 days with an engineer on site: first coil run, step depth adjustment, length calibration against a steel tape, and touch screen training. Our engineers have commissioned lines in 50+ countries since 2005, and the machines carry ISO 9001 and CE marking.

Power supply causes most delays on a glazed tile roll forming machine. Confirm site voltage, frequency and phase before release, because a 380 V 50 Hz cabinet does not run on 440 V 60 Hz without a transformer.

Frequently Asked Questions

Q: What is the difference between a glazed tile and a step tile machine?

A: The tooling is the same. Glazed describes the finish, a high gloss top coat that imitates ceramic glaze. Step describes the shape, a formed course every 250 to 350 mm. One glazed tile roll forming machine runs both, and the difference is the coil you load.

Q: What coil width do I need for a 1000 mm cover?

A: About 1200 mm. The extra 200 mm becomes the side rib and the lap. If the cover must be 1000 mm exactly, put it in the drawing, because a 1250 mm coil on the same section gives a different cover.

Q: How many tiles are in one square metre?

A: Divide one square metre by cover width times step length. At 1.05 m cover and 320 mm step that is 3.0 tiles. At 1000 mm cover and 350 mm step it is 2.9. Use the finished cover, not the coil width.

Q: Can the machine run 0.8 mm steel at full width?

A: Yes, with the 90 mm shaft and the 11 kW motor. The standard 76 mm shaft is rated to 0.6 mm at 1250 mm. Above that the step press needs more tonnage, so give thickness and width together.

Q: How fast does a glazed tile roll forming machine run?

A: 4 to 8 m/min including the pause for the step press. The mill moves faster between steps, but the quoted figure is what a buyer can plan a shift around. A 6 m/min line makes about 2,300 m in eight hours.

Q: Can it produce stone coated tiles?

A: Not from stone coated coil, because granules crack at the step and shed at the rib. Stone coating is applied after forming by a specialist coater, so the line supplies bare formed tile. Prepainted and PVDF coil run without change.

Q: Can I change the step length later?

A: Yes. A glazed tile roll forming machine keeps its rolls and takes a new step die and cut die. A second die costs a fraction of a new machine and takes two to four hours to fit, which is why buyers with two markets order both dies at the start.

Q: What is the lead time?

A: 45 to 60 days after drawing approval, plus two to three weeks for a second die set. Commissioning and training take 7 to 10 days on site. Spare dies, rollers and a wiring drawing set ship with every glazed tile roll forming machine.
