With diameters ranging from 600mm to 3600mm, our steel buoys can be used in inland rivers ,lakes and ocean.All steel plates are choosing from marine steel plate with hull thickness from 5mm to 12mm.
Starting from material seletion to final production, every step is taken care by highly qualified and experienced.Our ZAZ steel buoys are of steel construction and with excellent stability characteristics. All ZAZ Marine Steel buoys are made in accordance with IALA guidelines.
Our 1500mm Diameter Port Hand Buoys are characterized by their high shock resistance and stability. Metallic parts of the buoys (superstructure and tail) are made from hot-dip galvanized steel, and designed to provide a long service life under harsh marine conditions. They can be customized under client’s request, as well as to be made from stainless steel or marine aluminium.

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 and 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.
