- Configuration
- Galvanized steel
- Selected slat requirement
- Curved interlocking slats; nominal 80 mm pitch
Interlocking Steel Curtain and Overhead Coil
Curved Interlocking Steel Slats
The curtain is made of curved interlocking steel slats at a nominal 80 mm pitch and 0.8 mm thick, and it rolls up around an overhead barrel, leaving the ceiling free of tracks.
Vertical Guides and Bottom Bar
A selected 75 mm guide-section requirement runs at each side of the opening. The bottom bar, guide engagement and curtain-retention components belong to the same matched operating assembly.
Manual Hand-Chain Operation
The selected operation is a manual hand chain acting through the overhead mechanism. A motor, controller, remote and powered safety devices are not included in this manual door requirement.
Rolling Steel Garage Door Finishes
Light-Gray Coated Steel
The light-gray option is a coated finish over the steel curtain, with coating color, sheen and cut-edge treatment on the door's appearance reference.
Charcoal Coated Steel
The charcoal option keeps the same opening and curtain. Guides, bottom bar and headbox are matched to the coating schedule, since their base materials can differ from the curtain's.

Rolling Steel Garage Door Questions
Is this a sectional overhead garage door?
The curtain is made of interlocking steel slats and coils around an overhead barrel, so there are no ceiling tracks.
Does the door include an electric motor?
The selected assembly is manually operated by hand chain. A motor, controls and powered safety components would form a separate matched automation package.
What do the 3000 × 2400 mm dimensions describe?
They describe the selected clear opening. The fabricated curtain, guides, brackets and coil extend beyond that passage according to the final door detail.
Are the 450 mm and 150 mm reservations final installation dimensions?
They are selected planning targets for headroom and side room. The actual barrel, brackets, chain gear, guide arrangement and service access determine the required final reservations.
Can the rolling door be built for high wind or added security?
Yes. For coastal and high-wind sites we upgrade the guides, wind locks and curtain gauge and supply the wind-load calculation; for security we add reinforced locking. Tell us the wind zone and security level and we quote the upgraded door.
What is needed for a rolling garage door quote?
Send clear opening dimensions, jamb and head construction, available headroom and side room, floor levels, finish and quantity, plus the manual gear, locking and retention you want, any performance requirements, destination and installation responsibilities.
