Glen is a leading designer, manufacturer and supplier of marine mooring bollards, who can provide bollards with different capacities, shapes and materials applied to different berths, shipyards, jetties, wharfs, and ports. In the past decade, GLEN has rich experiences in helping client choose type, offer FEM and physical load test.

Mooring Bollard By many years of design, the bollards were kept finite elements and optimized geometrical shapes which ensure the safety and stability. The normal used material is cast steel, ductile cast iron and stainless steel, but the ductile cast iron is our first choice for its high corrosion resistance and high tensile strength which can save much time and cost in maintaining. The capacities and shapes on the table in this file are the normal used ones which do not mean we just can offer these! You can feel free to contact us for other capacities or shapes and we could offer custom...

The normal used material for mooring bollards are cast steel and ductile cast iron. Both of them have its advantages during applications. However some applications and operational conditions necessitate the use of specific materials. For example in extreme temperature of -20°C or below, regular cast iron becomes very brittle and easily cracked and is therefore not recommended. Similarly in hot humid environment where the water has high saline content cast steel is not recommended as it has a poor rate of resistance to corrosion. Advantage of Ductile Cast Iron More corrosion resistance than...

MATERIAL TEST According to GB/T1348-2009 QT450-10 and GB/T11352 ZG230-450, the required testing procedure of the mooring bollard consists of the following: Material certification From each metal pour from the casting process a sample must be taken. The sample should then have its material properties checked and certified by an independent third party. Dimensional accuracy Once the bollard is cast it should be thoroughly checked for dimensional accuracy with its supplied drawings. Design calculations Cross referencing both the material and dimensional properties of the bollard the...

There are two types moulding we usually used. One is wood mould, the other is lost foam mould.

Painting As the bollards are often used under marine environment, the good painting is most important. GLEN takes strict procedure for each step of painting. Epoxy painting for 1st layer and the 2nd layer, bituminous painting or polyurethane painting for top coat. The total DFT is about 300-350μ.

CUSTOM DESIGN Glen designs and produces the most popular style bollards yet provides custom design according to clients’ special requirements. Inspection Standard ► People’s Republic of China JTJ-98 Standard of Quality Inspection and Assessment for Port Engineering Construction.

Glen designs bollards following the standard JTJ297-2001, People’s Republic of China (2002) the technical code of subsidiary facilities for wharf. The above standard is equivalent to the following international standard: ► Actions in the design of Maritime and Harbor works BS6349: part 4 (1994) ► Ministry of transport, Japan ( 1999) technical note No.911-ship dimension of design ships under given confidence limits. ► EAU(1996) recommendations of the committee for waterfront structures ► Criteria for movements of moored ships in harbors - a practical guide ( 1995) PIANC report of PTC II-30 (...

The height of the mooring points should be such that vertical angles of the mooring lines will be as small as practicable not greater than 25 ° . GLEN mooring bollards are designed with a recommend max. Angle 45°. However lines can be taken to 60°without danger of slippage on the GLEN’s bollards. A variety of anchorage systems can be supplied and consideration should be given to the type most suitable for the deck and design and construction supporting the bollard. The normal used anchor is steel 45# grade 8.8 with H.D.G.
