GRT Rubber Technologies · Since 1880
We move industry.
Engineered rubber built for the hardest jobs on earth — conveyor belting, wear lining, sheet rubber, and impact protection that keep mines, mills, and plants running longer with less downtime. Made in the USA.
Solutions
The most extensive line in the industry.
One partner for the entire material flow — from the belt that carries it to the liner that survives it. Every product engineered to the application and backed by a performance guarantee.
Belts that take the hit.
FlexKing, TechFlex, DuraKing and HeatKing — up to 72" wide and 1,500 PIW, built for rips, impact, and heat.
Outlast steel 7–12×.
Rubber-ceramic, ArmorRing, and steel-backed liners that absorb impact, cut noise, and shrug off 700°F upsets.
Every compound, in stock.
SBR, nitrile, neoprene, EPDM, Viton and more — up to 72" wide by 2" thick. Home of Gorilla Red.
Clean, sealed load zones.
BeltSeal and TailSeal kits, canoe liners, and dust curtains that keep transfer points dust-free.
25 to 400+ tons.
3D-laser-scanned modular bed liners installed in under a shift — 77% more impact absorbed.
Designed to your site.
Molded parts and rail products cut on North America's largest table, modeled with DEM flow simulation.
Industries
Proven where it's hardest.
From hard-rock mines to grain elevators, GRT rubber runs in the operations that punish equipment the most.
Why GRT
Start-to-finish, under one roof.
GRT is vertically integrated — we compound the rubber, build the belt, cure it, engineer the solution, and stand behind it in the field. That's how we hit lead times others can't.
Every batch tested against the recipe before a pound hits the mill.
Belt built ply-by-ply and vulcanized on the Rotocure line.
3D LiDAR scans and DEM flow simulation, backed by a performance guarantee.
Site surveys, install supervision, and service that stands behind every order.
Results
The numbers our customers bank on.
Rubber-ceramic haul-truck liners still running past 46,000 hours in service.
Saved every year after GRT re-engineered the transfer chute with DEM simulation.
Increase in wear life after switching to GRT rubber-ceramic lining.
