NXF UNS A36 S235JR/St37-2/SS400/SM400A/A283C 119-D Zinc Layer Thickness:80um Mounting Bracket Cross

The galvanized carbon steel cross mounting bracket is manufactured through standardized stamping, finishing and galvanizing procedures. Strict process control ensures stable structure, accurate dimension and excellent anti-corrosion performance for engineering installation.

1. Raw Material Selection and CuttingHigh-quality carbon steel plates are selected as the base material with qualified toughness and bearing strength. According to specification requirements, the steel plates are precisely cut into standard blanks. Surface oil stains and burrs are removed to ensure flat and clean raw materials for subsequent forming.

2. Integrated Stamping and FormingThe cut steel blanks are placed on precision stamping molds for one-time cross structure forming. The whole process ensures symmetrical structure, uniform plate thickness and no stress deformation. The cross shaping is neat and firm to guarantee balanced multi-directional load-bearing capacity.

3. Precision Punching and DeburringStandard assembly holes are punched accurately according to installation standards. After punching, secondary trimming and deburring are conducted to eliminate sharp edges. Smooth hole walls ensure precise matching with threaded rods, bolts and gaskets for convenient assembly.

4. Surface Pretreatment CleaningAll semi-finished products undergo degreasing, sanding and rust removal treatment to completely remove surface oxide scale, oil and impurities. This treatment enhances the adhesion of the zinc layer and effectively avoids peeling and uneven coating.

5. Galvanizing Anti-corrosion TreatmentAdopt electro-galvanizing or hot-dip galvanizing technology to form a dense and uniform zinc protective film on the bracket surface. The layer isolates air and moisture, greatly improving rust resistance and durability in humid and outdoor working conditions.

6. Quality Inspection and PackagingFinished products are fully inspected in structure size, hole spacing, galvanizing quality and bearing performance. All qualified brackets are cleaned and packaged professionally to prevent scratches and deformation during transportation, meeting bulk engineering supply standards.
