Doshin Rubber, a subsidiary of KOSSAN group of companies, manufactures Engineered Rubber Solutions in both the Civil Engineering and Construction Industries. With over 38 years of experience, continual research in engineering designs, constant material and product development, as well as collaboration with designs experts, Doshin has the leading edge in the civil and construction industry for engineered rubber product solutions. We are capable to design and customize civil and industrial structures, from transportation infrastructure (Bridges, viaducts) to ordinary buildings, strategic structures (such as hospitals and emergency centres) as well as industrial facilities.
Dock fender is a bumper that is used to absorb the kinetic energy of a boat or vessel berthing against a quay wall, jetty and other vessel to prevent damage. We manufacture these fenders using high quality rubber to deliver impact for long term protection.
We produce dock fenders which are most suitable for an application depending on factors such as displacement of the vessel, dimensions, berthing structure, maximum allowable stand-off, tidal variation and other specific-berth conditions. The size of the dock fender unit is based on the berthing energy of the vessel.
We are able to customize different types of dock fenders according to desired specifications. Here are some of the types of dock fenders we produce:
1. CELL (CS Series Fender)
2. ARCH (V-Shaped Fender)
3. CYLINDRICAL FENDER (CT)
4. RIGID FENDER (DC, DD, SC)
We customize High Damping Rubber Bearing (HDRB) for the seismic protection of bridges. Our mega project such as the Longest Bridge in Southeast Asia, the 2nd Penang Bridge in Malaysia uses KOSSAN High Damping Rubber Bearing (HDRB).
We customize and design Elastomeric Rubber Bearings which are used for supporting vertical loads as well as for absorbing bearing rotations and horizontal displacements. It is commonly utilized for buildings, bridges and other civil engineering constructions because they are easy to install, durable and easy for maintenance.
We specialize in the following types of bearings and are able to design and customize according to your needs.
We design, produce and test to meet BS, EN, AS, AASHTO and other international requirement.
An expansion joint or movement joint is an assembly designed to safely absorb the heat-induced expansion and contraction of construction materials, to absorb vibration, to hold parts together, or to allow movement due to ground settlement or earthquakes.
We are able to produce expansion joints for various applications such as in buildings, bridges, sidewalks, railway tracks, piping systems, ships, and other structures.
The sensitivity of mill and mining areas are crucial to the quality of products used in the building process for the protection of the area and workers.
Our accredited laboratories are equipped with comprehensive testing equipment to carry out stringent testing in accordance with International Standards.
Trommel panels are installed at the end of grinding mills and scrubbers with rotary drum material separators for screening and grading without process vibration.
Rubber screens which we produce are designed to absorb impact, reduce pegging and blinding as well as improve wear life in coarse and heavy duty applications.
We are also able to customize liners which are important for containment of fresh water and contained water.
Trains and railway vehicles cause vibrations to be transmitted through the ground causing problems with and possible damage to adjacent structures, buildings and their occupants.
We provide a one-stop solution to address these issues through our engineered rubber customized products such as floating slab tract bearings, lateral bearings and rubber wedge to improve the railway system.
Pot Bearings are suitable for high loads, displacements and rotations.
Pot Bearings basically consist of an elastomeric pad restrained in a metallic pot. The pad is then compressed by a piston with bearing pressures depending on the design standard required.
We are capable to design, fabricate, test and install pot bearings up to vertical load of 50,000 KN.
