Sinotop Fence has many years of experience in the production of metal fence panels, producing various security fencing that meets Australian, American, and European standards.
Galvanized steel pipes and wires are inspected for size tolerance (±0.2 mm) and zinc coating thickness (≥275 g/m²) to ensure compliance with ASTM/EN standards.
Galvanized Pipes are cut into standard or custom sizes to ensure consistent assembly on site.
The steel plate is fed into a high-speed punch press, and the pressure of the die is used to punch the steel plate into a preset spear top shape.
Pre-punch holes in the pipe. This step is to facilitate subsequent installation and welding.
Wires are straightened and welded into panels by automated welding machines. Welding points are regularly tested for strength (typically ≥500 N).
Mesh panels are joined with uprights and crossbars. Continuous, uniform welding maintains straightness and ensures long service life.
Cleaning and roughening the surface by spraying high-speed abrasive particles. It can remove impurities such as rust, oil, and scale.
The phosphating film itself has a certain anti-corrosion ability and can provide excellent adhesion of paint, powder coating, or other organic coatings.
The surface is brushed or sprayed with zinc-rich epoxy primer (dry film thickness ~40–60 µm) for enhanced rust protection in outdoor environments.
Each batch undergoes dimensional checks, weld inspections, and corrosion tests (e.g., salt spray ≥500 hours). Only approved products are packed and shipped.
