Industrial Door Technical FAQ

Maximum width depends on door type, wind load, panel or curtain structure and track design. Large openings should be checked with drawings so the correct door system and reinforcement can be selected.

Maximum height varies by product. Sectional doors, rolling doors and folding doors can all support different height ranges. Building clearance, motor location and structural support must be confirmed before final design.

Yes. Industrial doors are commonly produced to project opening sizes. Please provide clear width, clear height, wall structure, indoor or outdoor position and any drawings for accurate customization.

Confirm clear opening width and height, side room, headroom, backroom, floor level, wall material and any obstacles near the opening. These details affect track type, motor position and installation method.

Motor brand options depend on door type and project requirements. Common choices include Chinese industrial motors and selected international brands. Voltage, frequency, duty cycle and control method should be confirmed before selection.

Confirm local voltage, phase and frequency, such as 220V single phase, 380V three phase, 50Hz or 60Hz. This ensures the motor, control box and electrical components match the destination market.

Yes, motor and control systems can often be selected for 50Hz or 60Hz power supplies. The buyer should confirm the local electrical standard before production to avoid mismatch on site.

Motor power depends on door size, weight, opening speed, usage frequency and balancing system. Larger or heavier doors require stronger motors and suitable control protection.

Wind class depends on the door structure, opening size, guide rail strength and reinforcement design. Outdoor doors should be quoted with local wind load requirements or project specifications.

Hurricane-rated requirements must be checked against the destination market standard and required test documentation. Share the wind pressure, opening size and local code so suitable wind-resistant options can be reviewed.

Yes, many industrial doors can be installed outdoors when configured for wind, rain, corrosion and temperature conditions. Exterior installations usually require stronger sealing, guides and weather-resistant components.

Wind resistance can be improved with stronger guide rails, reinforced slats or panels, wind bars, heavier tracks, better fixing points and correct installation into a suitable wall structure.

Photo eyes are safety sensors installed across the door opening. If a person, forklift or object blocks the beam, the door stops or reverses to reduce collision risk.

A light curtain uses multiple infrared beams to monitor a larger area of the opening. It provides broader protection than a single photo eye and is useful for high speed doors or mixed traffic areas.

Emergency stop buttons are recommended for automated industrial doors, especially in busy work areas. They allow operators to stop door movement immediately if unsafe conditions occur.

A safety edge is a pressure-sensitive strip installed on the door bottom or leading edge. If it contacts an obstacle, the control system stops or reverses the door.

Lubrication frequency depends on door type and usage. High-cycle doors should be checked more often. Tracks, hinges, chains, springs and moving hardware should be maintained according to the door system.

Yes. Common replacement parts can include motors, control boxes, sensors, rollers, hinges, springs, curtains, slats, seals and hardware. Providing the order record or photos helps identify the correct part.

For normal industrial use, inspection every 3 to 6 months is common. High-traffic, cold storage, dusty or outdoor environments may need more frequent checks.

Use cleaning methods suitable for the door material. Keep tracks free of debris, wipe panels or curtains with mild cleaners, and avoid spraying water directly into motors or electrical controls unless they are protected for that environment.
