A loading dock curtain is a PVC strip curtain hung across a dock door or truck bay so that people, pallets and forklifts can pass while the opening stays partly closed. At a busy dock the door may be open for hours, letting in heat, dust, rain and insects. A curtain reduces all of that without slowing the work.
This guide covers how to choose strips, size and overlap for dock doors, and how to keep the curtain working in a heavy-duty setting.

Dock doors are among the most open doors in a building. Without a curtain, hot outdoor air and dust flow into the warehouse, and cooled air flows out. A curtain also helps keep birds and flying insects out, and gives a little shelter from wind and rain.
Dock doors suit wide, thick strips, such as 300 x 3 mm or 400 x 4 mm. Ribbed strips handle the contact with pallets and forks better than smooth ones. See our guide to ribbed vs smooth strips for forklift doors.
Measure the opening width and height, and add a little extra on each side. Keep the bottom edge about 10 to 20 mm above the floor. For tall doors, use thicker strips so they hang straight and do not twist in the wind.
For vehicle-entry doors, you can also use movable or sliding PVC curtain systems that open wider than a fixed strip curtain. They give a good seal when closed and clear the opening for trucks. We can advise on rail systems that match the door.
If the dock is cold-chain, use polar strips and a high overlap. If it is an ambient dock in a hot area, standard clear strips are fine. Tell us your temperature so we can match the grade.
A curtain does not stop a vehicle and is not a safety barrier. Keep clear strips so drivers can see through, and use signs and mirrors at blind spots. Add dock bumpers and wheel chocks for the trucks themselves.
Clean the strips regularly and check for cuts and tears. Replace single strips as they wear. Keep a stock of spares so that a damaged strip is fixed on the day. See how to clean and maintain a PVC strip curtain.

Usually yes, because they resist scuffs from pallets and forks.
