Ceiling T Grid Roll Forming Machine | Main Tee & Cross Tee Production Line – PUTAI - Tianjin, China

PUTAI Ceiling T Grid Roll Forming Machine – Automatic Main Tee and Cross Tee Production Line

The PUTAI ceiling T grid roll forming machine is a fully automatic, PLC-controlled production line that turns galvanized or pre-painted steel coil into the T-shaped main tees and cross tees used in suspended ceiling systems. Decoiling, levelling, forming, punching and cutting all run in one synchronized sequence at speeds up to 40 m/min, so a single operator can take the line from coil loading to finished bundles. It is built for building-materials manufacturers and ceiling-system producers who need consistent, high-volume output for commercial contractors.

Key Features

• Fully automatic operation from coil to stacked bundle, run by one operator per shift
• Servo tracking shear cuts to length without stopping the line, with ±0.5 mm cut accuracy
• Online hydraulic punching creates connector slots and holes for cross-tee interlocking
• Profile straightness held within ±0.5 mm per metre, reducing installation problems on site
• Modular tooling lets one machine produce both main tee and cross tee profiles
• Recipes stored on the HMI touch screen, so profile and length changes take seconds
• Automatic stacker and bundling system available for a complete packed output

How the Production Line Works

• Decoiling: A hydraulic decoiler (3T or 5T optional) feeds the strip under constant tension
• Levelling and guiding: A precision leveller removes coil set and keeps the strip centred
• Roll forming: The strip passes through 14–18 progressive stations to form the T profile
• Punching: An online hydraulic unit punches connector slots and holes
• Servo cutting: The tracking shear cuts to programmed length while the line keeps running
• Stacking and packing: Finished bars are collected by the auto-stacker and bundled for shipping

Profiles Produced

• Main tee (main runner): 38 × 24 mm, 32 × 24 mm, 24 × 24 mm, the load-bearing member hung from the slab by hanger wire
• Cross tee: 26 × 24 mm, 24 × 24 mm, clipped between main tees at 600 mm or 1,200 mm centres
• Custom profile sizes available to match regional ceiling standards

Frequently Asked Questions

• What is the delivery time? Typically 45–60 working days after deposit, depending on configuration and tooling.
• Can one machine make both main tee and cross tee? Yes. Modular tooling and an adjustable punching die let several profiles run on one base frame, so buyers don't need two separate lines.
• What do you need to prepare a quotation? A profile drawing or sample, material thickness, required speed, and your local voltage and frequency.
• Is the machine difficult to operate? No. All settings are stored on the touch screen, and one trained operator can run the full line, change cut lengths and switch profiles.
• Do you offer overseas installation? Yes. On-site commissioning by PUTAI engineers or remote guidance is included in the service package.
• What voltage does the machine use? Standard is 380V/50Hz/3-phase, and it can be built for any local power supply.
