What to Check During Door Acceptance

What to Check During Door Acceptance

1、Appearance & Workmanship

Check the door surface for scratches, dents and obvious color difference. All hardware is firmly installed without rust. Profile edges are smooth and burr-free.

2、Opening & Closing Operation

Test door operation. Folding doors slide smoothly with synchronized leaves. Roller shutters run stably with precise upper and lower limits. Manual operation works normally when power is off, without jamming or abnormal noise.

3、Dimension & Installation

Actual door dimensions match the drawings. The door frame is firmly mounted without tilting. Gaps around the door are even. Forcible installation is forbidden to prevent hidden damage.

4、Sealing & Weather Resistance

Sealing strips are intact with no breakage or falling off. Outdoor door structures for waterproofing and wind resistance have no defects.

5、Electrical Safety

Internal wiring is tidy. Remotes and switches work properly. Safety functions such as obstacle detection are effective.

6、Documents & Accessories

Verify the product certificate and manual, count all accessories, and confirm the warranty terms.
