What are the Correct Installation Steps for Industrial Doors?

Installing an industrial door requires precise measurement, proper alignment, and secure fixing. Below is a step-by-step guide to ensure a safe and efficient installation process.

Step 1: Industrial Door Preparation and Measurement

Before installation, measure the door opening carefully and check all dimensions. Identify the highest point on the ground.

• Keep a clearance of 0.5–0.8 cm between the lower guide wheel and the door panel
• Maintain 6 cm distance between the hanging rail and the door panel
• Fix the buried rail firmly to ensure it can support the weight

Pendant spacing depends on door size:

• Over 10㎡: 60–80 cm
• Under 10㎡: 80–100 cm

Leave 15–20 cm at both ends of the rail. Use standard ￠10 expansion screws, or wall-through bolts for hollow walls. Ensure the rail level error is within 5 mm.

Step 2: Industrial Doors Panel Installation and Adjustment

Hang the door panel using screws, washers, and nuts. After installation:

• Adjust vertical alignment and balance
• Control bottom clearance at 0.5–0.8 cm
• For double-opening industrial door, align both panels based on the centerline

Step 3: Industrial Door Guide Wheel and Ground System Installation

Install guide wheels to stabilize the industrial door:

• First guide wheel: 5 cm outside the doorway
• Second guide wheel: at 60% of door width

Additional steps:

• Weld the middle collar securely
• Install ground pin with 2 mm protrusion
• Welding spacing: approx. 50 cm
• Handle height: 130 cm (outer), 120 cm (inner)
• Install latch 5 cm below the handle

Step 4: Test Operation

Check the overall performance of the industrial door:

• Apply lubricant to hanging wheels
• Smooth and polish welded areas
• Apply protective paint

Step 5: Install the Baffle

Install the baffle based on the number of pendants:

• Each pendant corresponds to one support shelf
• Ensure the baffle is vertical and balanced
• Keep joints clean and visually neat

Step 6: Industrial Doors Final Cleanup

After installation is complete:

• Clean the worksite
• Remove debris
• Pack tools and restore the area
