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 donâ??t 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 the durable installation of products. Vinhhung parapets are hot-dip galvanized according to AASHTO M111 (ASTM A123) which would bring the maximum life for products. The high quality of Vinhhung parapets is affirmed when reaching out to the region with export orders to projects in Bruneiâ?¦

1. PRODUCT OVERVIEW VHB Pot Bearings made by Vinh Hung Investment and Production Company Limited (Vinh Hung IP) are in compliance with standards (TCVN 10268: 2014, AASHTO LRFD: 2007 â?? Section 18, ASTM D 5212 â?? 03, BS5400, EN1337, KS4420). 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: Fixed pot bearings and sliding pot bearings. Fixed pot bearings: The bearings only allows the head of structure to have rotary movement and transfer the pressure through a fixed point. Sliding pot bearings: 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 the salt-spraying test in 6000 hours.
