Our Story

GTR Manufacturing proves its mettle within the sheet metal industry.

Brockton, MA - When GTR Manufacturing Corp. stepped into the ring of custom sheet metal fabrication, electro-mechanical assembly, and painting/powder coating/silk screening in 1973, it found that despite the major, established competition within the industry, a family-owned business can thrive if it operates on three sound principles of business - Capability, Quality, Reliability.

With steady growth and a stable workforce GTR has earned a reputation for superb quality and 98% on-time delivery. This has become known as the GTR Advantage.

Unlike many of its competitors within the industry that choose to risk losing quality control through outsourced services, GTR maintains in-house capabilities - including mechanical assembly, electro mechanical assembly, as well as cables, harnesses, painting, powder coating and silk-screening processes. Complete control is maintained throughout the entire production process, allowing the highest quality standards and tightest delivery schedules to be rigidly adhered to.

Capability, quality and reliability have resulted in sales growth over the last 10 years , as well as realizing steady growth for 40 years. In 2000, GTR expanded its facility in order to accommodate customers’ needs for more capacity. Within the 52,000 sq ft facility, clients can check on the progress of their order - through manufacturing, flex-laser cell, electro-mechanical and finishing - and see quality in the making. Perhaps another reason why GTR consistently receives stellar customer report cards.

Having ISO Certification/UL Approval, GTR is able to respond on-demand to quotes, order reschedules, design changes and other unexpected occurrences that typically backlog the competition.The company’s position of leadership, reputation and long-term financial stability allow the company to buy raw materials in bulk, and maintain inventory for customers, shipping product as it is scheduled.

GTR sales, management and design engineering staffs have expertise in a wide range of industries so they better understand clients’ and the industry’s changing needs. Working in close partnership with customers, both in the development and refinement of product designs and production process planning, GTR staff are accountable that each job is done right, on time and within budget. Such relationships have resulted in many successful, profitable product introductions for GTR customers, and in many rewards for GTR.

GTR serves large and small customers, from individual entrepreneurs to large multinational corporations in the medical, electronics, electrical, chemical, surveillance, and environmental industries. GTR has its goal in sight. To become the premier custom sheet metal/box build/finishing manufacturer in New England. The company, and its customers, realize that in order to be successful it helps to have an advantage. The GTR Advantage continues to rise above the competition.
