All our products are developed in-house by multidisciplinary teams, with expertise tailored to each field of application.
Continuous improvement of our product range enables us to support our customers' technical developments and extend the service life of refractory linings.
Tailor-made refractory solutions to optimize the life and performance of your installations.
In high-temperature industries, thermal and mechanical stresses accelerate equipment wear and increase the risk of production stoppages. To counter this, TRB develops customized technical solutions that enhance the durability of your facilities, optimize their performance and limit unplanned stoppages.
Our expertise covers a wide range of industrial sectors, including cement, foundries, iron and steel, lime kilns, heat treatment and ferroalloys.
With nearly 80 years' experience, TRB is the trusted partner of manufacturers worldwide in their quest for performance, reliability and sustainable solutions.
PUREBLOX 1400, our insulating refractory innovation, is a solution that poses no health risk to operators and withstands temperatures of up to 1400°C.
Developed by our R&D and Design Department, the PUREBLOX 1400 contains no CMR-classified ceramic fibers and withstands temperatures of up to 1400°C.
With a thickness similar to current insulating materials (310 mm), the PUREBLOX 1400 solution offers thermal performance equivalent to that of CMR-classified ceramic fibers.
ECOFIB precast shapes for extreme environments
In high-temperature industries, strength and reliability are essential. TRB has been designing ECOFIB precast shapes for over 25 years, formulated to withstand the most severe thermomechanical stresses.
With an expert design office and a wide range of products, we produce over 400 tonnes a year of metal fiber-reinforced solutions, combining performance, durability and rapid installation.
