With diameters ranging from 0.6m to 3.6m, our steel navigation buoys can be used in inland rivers, lakes, and oceans. All steel plates are chosen from marine steel plates with hull thicknesses from 5 mm to 12mm, quite solidly.
Why Choose Our Steel Navigation Buoys?
Our ZAZ steel buoys are made of steel construction and have excellent stability characteristics. All ZAZ Marine Steel buoys are made following IALA guidelines.
All navigation buoys are successfully being used to demarcate a variety of marine and coastal areas, such as waterways, marinas, rivers, port entrances, ocean and offshore locations.
Their high shock resistance and stability characterize them. Metallic parts of the buoys (superstructure and tail) are made from hot-dip galvanized steel, and are designed to provide a long service life under harsh marine conditions. They can be customized under the client's request, as well as be made from stainless steel or marine aluminum.

About Welding:
* We use CO2 welding, manual welding, Submerged arc auto welding, and automatic welding.
*All weld surfaces should be visually inspected, the weld wave should be uniform, and the edges of the weld should be smoothly transitioned to the base metal,
The shape and size of the weld should meet the requirements of the drawing, and the surface of the weld shall not have cracks, slag, unfused, porosity, weld tumors, or arc pits;
*We use ultrasonic flaw detection technique to complete the welding testing.
About Painting:
* We use epoxy paint.
*Shot peening pretreatment will be the first step, and then we will paint the anticorrosive paint within 4 hours after pretreatment.
*We use high-pressure airless spraying as much as possible.
* For the parts that are difficult to spray, such as welding lines and frame edges, we usually brush one or two layers before formal coating.
