Vinh Hung specializes in manufacturing safety parapet for transport, civil and industrial works. Parapet products are manufactured according to the typical design of the company or according to customer drawings. Our Parapet products conform to the standards: BS EN 1317, TCVN 11823-13: 2017. All parts of the parapet are processed on modern machinery lines, high precision, in order to facilitate the installation and durability of the product.
Parapets are the outermost of the bridge deck. Handrails are used to protect vehicles and people when a collision occurring and direct the vehicles on bridges.
Parapets are mainly used steel, aluminum alloy, wood, reinforced concrete. Installed on the bridge concrete barrier, parapets donot only ensure traffic safety but also increase the aesthetics of the whole bridge.
Parapets consist of column system, handrails and the middle bar which are hot-dip galvanized or electrostatic painting with multiple types, sizes and designs. Parapets aesthetics are required very high when designing, especially the bridges in the city area or in the important roads.
All details of the parapet are processed on modern machinery lines with high precision and skilled workers to improve job efficiency as well as durable installation of products.
Vinh Hung parapets are hot-dip galvanized according to AASHTO M111 (ASTM A123) which would bring the maximum life for products.
The high quality of Vinh Hung parapets is affirmed when reaching out to the region with export orders to projects in Brunei.

VSR Elastomeric Bearings made by Vinh Hung investment and production Co., Ltd (Vinh Hung IP) are in compliance with TCVN 10308: 2014, AASHTO LRFD Section 18, AASHTO M 251 96 (2011), BS5400, EN1337, KSF4420
VSR Elastomeric Bearings have been used in road bridge constructions, with a maximum load of 5000kN.
2Â PRODUCT CHARACTERISTIC
Elastomeric bearings are composed of rubber and steel plates which are chemically bonded through vulcanization. The thickness of the bearing is calculated to ensure the load, displacement and rotation as the requirement.
Elastomeric bearings are simple geometric structures, bringing convenience during the installation, operation and maintenance. In addition, this type of bearing provides high resistance of vibrations impacted to the bridge span structures and piers.
VHC spherical Bearings/ Bridge bearing manufactured by Vinh Hung Investment and Production Company Limited (Vinh Hung IP) are capable of withstanding the high loads and movements suitable for structures requiring the rotary angle equal or bigger than 0.015 rad in all directions. VHC spherical bearings are designed and manufactured according to current standards such as:Â TCVN 11823, AASHTO LRFD, ASTM D5977, EN 1337,
2. PRODUCT CHARACTERISTICS
VHC spherical bearings/ bridge bearing possesses a bottom plate (6) which has a PTFE sliding plate (4) on it is upper curved surface. A convex calotte (5) is placed on top of this, which, thanks to it is polished hard-chromium plated surface, can slide within the lower part with low friction, thus facilitating rotations about every axis.
A second sliding plate of PTFE (4) is recessed into the upper surface of the calotte. Together with the upper plate (2) above it, this accommodates longitudinal and/or transverse sliding movements of the superstructure, if required. To reduce sliding resistance to a minimum, the lower surface of the top plate features a polished stainless steel sheet.
In the case of bearings which should allow movement along one axis only, the direction of movement is controlled by guiding bars (3). In the case of fixed bearings, the top plate does not have a stainless steel sheet.
The bearing is connected to the superstructure and the substructure by means of anchor dowels (1) or threaded sleeves (depending on design), or alternatively by means of separate anchor plates with shear studs.
To ensure the long-life durability, VHC spherical bearings are protected against corrosion by the following methods: coating with two-component epoxy, PU-based painting (Polyurethane), hot-dip galvanization according to ASTM A123 standards and especially the Al-Mg spray coating method (at the ratio of 5% Al and 95% Mg) which ensure the anti-corrosion durability of up to 100 years, this method is proved by the salt-spraying test in 6000 hours (8-hour dry-wet cycle) according to ASTM B117

VHB Pot Bearings are capable of withstanding high loads, displacements and rotation angles. This type of bearing is suitable for middle-range span structure, continuous bridge structure, etc. with a load capacity of up to 60000kN or above depending on projectsâ?? requirements. VHB pot bearings have a well-shaped structure, superior design, which are convenient for installation and maintenance during operation.
2. PRODUCT CHARACTERISTICS
VHB pot bearings are comprised of 4 main parts: top plate, piston, pot plate and elastomeric pad. The elastomeric pad is placed inside of pot plate, under the pressure of the load, the elastomeric pad experiences the temporary deformation inside the pot plate volume, it is capable of withstanding the forces and allows the movement as well as rotation along the horizontal axis.
Piston and pot plate work as the connecting parts between the structures. Besides, the plus guiding part can be designed to limit or allow the movements as required from the structures.
Pot Bearings are divided into 2 main types:Â Fixed pot bearings and sliding pot bearings.
Fixed pot bearings:Â The bearings only allows the head of structure to have rotary movement and transfer the pressure through a fixed point.
Sliding pot bearings:Â This type of bearings includes Free sliding bearings and Guide sliding bearings, which allows the dead to have both rotary movements and unidirectional or multidirectional movements.
To ensure the long-life durability, VHB pot bearings are protected against corrosion by the following methods: painting with two-component epoxy coat, PU-based painting (Polyurethane), hot-dip galvanization according to ASTM A123 standards and especially the Al-Mg coating spraying method (at the ratio of 5% Al and 95% Mg) which ensures the anti-corrosion durability of up to 100 years, this method is proved by
