BOLLARD CATALOGUE

Product catalog summary

Purpose and Load Rating
The primary function of mooring bollards and cleats is to secure vessels to a berth using mooring lines. The load rating required for these bollards and cleats is determined by factors such as current, wind, and wake, and should be assessed by a qualified engineer following a mooring analysis.

Materials
Bollards and cleats are manufactured from cast steel, ductile cast iron, or gray cast iron, each with specific standards and properties:

Cast Steel: High strength, impact resistance, and ductility, but more expensive and requires corrosion protection.
Ductile Cast Iron: High strength and corrosion resistance, less expensive than cast steel, but lower ductility and impact resistance.
Gray Cast Iron: Least expensive, good corrosion resistance, but low strength and impact resistance.

Heat Treating
All cast bollards and cleats must undergo heat treatment to meet ASTM or BS standards, ensuring the mechanical properties conform to requirements.

Types of Bollards
Bollards and cleats come in various shapes, sizes, and capacities, including Single Bit, Double Bit, T Head, and Cleats. Specifications such as height, head size, and load capacities should be specified.

Coating
To protect against corrosion, bollards and cleats are coated with epoxy, polyurethane, hot dip galvanizing, or bitumastic coatings. A rust preventative primer is applied initially, with the final coating applied post-installation.

Testing
Post heat-treatment, bollards undergo chemical analysis and mechanical properties testing to ensure quality.

Main Products
The catalogue lists various bollard types with their capacities, materials, and coating systems:

Single Bit Bollards: 20MT to 225MT, Cast Steel.
Double Bit Bollards: 10MT to 200MT, Cast Steel.
T Head Bollards: 30MT to 150MT, Cast Steel.
Cleats: 10MT to 50MT, Cast Steel.
Bolted Pillar-Bollards: 10MT to 100MT, Gray Cast Iron.
Twin Horn Bollards: 10MT to 150MT, Gray Cast Iron.
Tee-Head Bollards: 10MT to 200MT, Gray Cast Iron.

Packing
Products are packed using wooden or steel pallets.

Sand Casting Process
The document outlines the sand casting process, which includes obtaining casting geometry, pattern making, core making, molding, melting and pouring, cleaning, and additional processes before delivery.

XI'AN SURE WELL IMP. & EXP. CO., LTD. \JjL • Polyurethane coatirtQ •Bitumastic coating When bollards and cleats supply from manufacturer, the bollards and cleats should with a rust preventative primer at least, perfectly compatible with expected top coating, to protect them from corrosion until final coating can be done at the jobsite. Since the installation of most bollards includes filling the core with concrete and filling the anchor bolt counter bores with non shrink grout, it is recommended that the top coat of the coating system be applied after installation. All our bollards are tested...

CO., LTD. j^fljj HELLOHASEA The various steps in the production of castings are briefly summarized for the benefit of those who may be unfamiliar with foundries and the casting process. Obtaining the casting geometry The traditional method of obtaining the casting geometry is by sending blueprint drawings to the foundry. This is usually done during the request for quotation process. However, more and more customers and foundries are exchanging part geometry via the exchange of computer aided design files. Pattern making The pattern is a physical model of the casting...
