Company
PT Piala Mas Industri
Founded in 1978 in Singosari, Malang. From a two-man workshop to a bus body manufacturer with a 5+ hectare site and a capacity of 1,500 units per year.
Who we are
Founded in 1978, still on the same track.
Karoseri Piala Mas was established in 1978 by two founders, Mr. Soetrisno and Mr. Haliman Halim. Over time the business grew into PT Piala Mas Industri, with production facilities at Jl. Bodean Krajan No. 09, Toyomarto, Singosari, Malang.
We put precision into every stage: design planning, material selection and the final finishing touches. The goal is simple — every vehicle leaving our workshop meets high quality standards, is safe to use, and stays competitive in the national market.
Company motto
Emerging Forward
With the equipment and technology we work with today, our product quality rivals other body manufacturers in East Java. Many of our clients, both within and beyond East Java, have told us they are satisfied with what we build and how we serve them.
We handle every type and brand of chassis, including premium ones such as Hino, Mercedes-Benz, Volvo and MAN, to match your requirements. The frame uses steel pipe for structural strength, ceilings and side panels use PU material in the latest designs, and the whole body is fitted with sound-dampening material to reduce road noise and outside heat.

How we work
Five reasons to trust us with your bus body.
Proven experience
48 years of building bus bodies — not one or two projects, but decades of work on structure, panels and interiors.
Quality craftsmanship
Attention to detail in every build, from panel joints to interior stitching that holds up over time.
Customer-focused solutions
Specifications are designed around your business requirements, not forced out of a ready-made model in the yard.
Comfort & functionality
The cabin is designed for a better passenger experience: space, circulation and cooling that actually work every day.
A partner you can trust
We stay with your fleet after the unit is on the road — our job does not end at handover.

Who we serve
Trusted across sectors.
City operators, tourism fleets, government agencies and schools all need something different. We do not force one recipe on everyone — the specification comes from how the unit will be used.
