An International
Heavy-Industry Group

Rainbow Group is an international heavy-industry group with a unified presence across Japan, Sri Lanka, and the United States. We operate through three specialized divisions — Rainbow Japan, Rainbow Lanka, and Rainbow USA — each focused on the specific needs of their market while sharing the group's standards, network, and capabilities.

Our origins are in heavy machinery trading. Rainbow Japan has been sourcing, inspecting, and exporting quality used construction equipment from Japan to buyers worldwide for nearly two decades. Japan's well-maintained machinery market, combined with our deep local knowledge, allows us to offer international buyers exceptional value.

In Sri Lanka, Rainbow Lanka has grown into a leading provider of crane rental and heavy lifting services, supporting the country's infrastructure development and its growing renewable energy sector. Our crane fleet and experienced team handle everything from routine lifts to complex engineered operations.

Rainbow USA extends the group's reach into North America, providing heavy machinery sales and specialized industrial manpower solutions to US-based clients and international projects.
