Karur, Tamil Nadu — Coach-Building Belt

BUILT IN THE
HEART OF TAMIL
NADU'S COACH BELT.

RR Hevirex Coach Builders operates out of Karur, Tamil Nadu — a region long recognized as one of South India's key centers for bus body building. We manufacture bus seats, not bodies, which means seating is the whole business, not a side operation. Every seat that leaves our facility is built to be sat in for hours at a stretch, on long-haul routes, tourist circuits, daily school runs, and everything in between. We work directly with transport operators, tourist bus owners, school and college administrations, corporate fleet managers, and bus body builders across the region.

Why RR Hevirex

Nine models, one manufacturer.

Nine models, one manufacturer

From a budget-conscious commercial fit-out to a fully loaded luxury pushback, you're ordering from one team that understands the whole range — not choosing between different suppliers for different tiers.

Full customization, not a catalog

Upholstery, safety grade, hardware, and even seat colour are decided per order, not picked off a fixed price list.

We come to you

Our team can visit your location, discuss the order, and — where needed — close and sign the deal on site.

Straightforward billing

GST-compliant invoicing as standard, with cash-order billing available where appropriate. Every quotation lays out pricing, taxes, and terms clearly before you commit.
