Quality Control

Seven inspection stages stand between the production line and your site.

01

Incoming Material Inspection

Steel, aluminum, motors and electronics are verified against spec before entering production.

02

Production Inspection

Cut, bent and welded parts are checked for tolerance and finish during fabrication.

03

Assembly Inspection

Mechanical assembly is verified — alignment, fasteners and moving parts.

04

Electrical Testing

Wiring, controllers, motors and safety devices are powered and tested.

05

Running Test

The finished gate or door runs full cycles under observation.

06

Final QC

A final inspector signs off appearance, function and documentation.

07

Packaging Inspection

Export packing is checked — protection, labeling and completeness — before loading.
