A guide to technical and engineering specifications required when choosing and installing roller shutter doors in factories and large warehouses.
Slat Thickness and Weight per Square Meter: Relation to Door Rigidity
In industrial doors, we steer completely clear of lightweight slats, relying on galvanized steel with thicknesses starting from 1.0 mm up to 1.5 mm, sometimes double-walled. The weight per square meter here is substantial, which is structurally required to provide enough stiffness to prevent slat buckling under mechanical pressure or minor impacts from moving equipment.
Wind Resistance and Lateral Anchoring Systems Specialized for Wide Spans
When a door's surface area exceeds 25 square meters, it acts like a large sail affected by wind forces. If standard side tracks are used, the door could blow out completely. Therefore, industrial specifications utilize extra-deep tracks equipped with wind locks that grip the shutter slats, preventing them from slipping out regardless of external wind speeds.
Motor Type and Duty Cycle Calculation for Frequent Operation Without Overheating
Standard motors trip on thermal overload if operated 3 or 4 times consecutively, which is unacceptable for logistics and warehouses. Here, we select 3-phase side motors with a high duty cycle rating. These motors are engineered to operate continuously without overheating or tripping overload switches, ensuring loading and unloading activities never stall.
Wicket Doors Integrated into the Shutter for Emergency Exits
A smart solution in the engineering design of large doors is integrating a small pedestrian door—or wicket door—within the shutter body itself. This door allows workers and staff to pass through easily without having to cycle the giant door every time, saving electricity, reducing motor wear, and serving as a quick emergency exit.
Industrial Safety Systems and Logistic Controls for Truck Traffic
Industrial door safety includes installing motion radars that open the door automatically as a truck approaches, magnetic loops buried in the ground (loop detectors) that sense forklifts, and traffic light signals. Organizing entry and exit in this manner completely prevents collisions and protects the facility's assets.
