Carbon steel drum that winds the curtain when a roller shutter door opens.
4 inch diameter and 3000 mm length fit standard commercial and industrial openings.
Uniform wall and straightness keep slats tracking evenly across the full width.
Bore, wall thickness and surface finish can be customized for your drive.

In a roller shutter door the drum is the member the curtain wraps around. It carries the whole rolled-up curtain, takes the torque of the motor or the manual drive through the shaft, and has to stay straight while doing it, or the slats wander and the door starts to rub. This carbon steel roller shutter drum is built for industrial and commercial shutters: a 4 inch diameter tube in 3000 mm length, roll-formed for a uniform wall, with custom work available on the bore and the ends.

Size the drum to the opening and to the curtain, not to the catalogue. The working length of the drum should extend past the opening width so each bracket gets full support with room for adjustment, and the diameter must give the curtain space to roll up without stacking so tight that the slats rub. Carbon steel suits dry indoor and covered openings; where the door sees weather, specify a coated or galvanized finish so the drum body does not start rusting under the curtain.

On installation, roll the drum across a flat floor first. Any visible bend or radial runout becomes noise and bearing wear once the door is running, so straighten or reject before mounting. Set both end brackets on the same horizontal plane, keep the welds at the end plates clean and free of porosity, and seal cut ends with anti-rust paint so moisture cannot creep into the wall. In service, check the drum after any work on the door, and keep the curtain centred so one side does not wear faster than the other.

FAQ

Q1. How does drum straightness affect the door in daily use?

A bent drum makes the curtain wander sideways as it rolls, which wears one guide rail faster than the other and eventually jams the door. Rolling the drum on a flat floor before mounting, and checking runout at both ends, catches the problem while it is still cheap to fix.

Q2. Why does my shutter get noisy after a year?

Nine times out of ten it is wear, not mystery. A drum running out of level loads one bearing, the slats rub on one guide, and the whole assembly starts to talk. Level the brackets, check the drum for runout, and keep the curtain centred before the noise turns into a repair bill.

Q3. Do I have to replace the whole drum if the surface rusts?

Only if the rust has eaten into the wall. Surface blooms from a scratch or an unsealed cut end can be cleaned, treated and touched up with anti-rust paint, and the drum keeps working. If the wall thins or the tube deforms, that is when a new drum is the sensible answer.

Q4. What payment terms do you accept?

T/T, L/C at sight and other internationally accepted terms. The exact terms are agreed with you before production starts, because the payment schedule has to match the order value, the shipping method and the delivery schedule you need — which is also why we confirm them up front rather than after shipment.
