In-House Metal Grinding & Metal Sanding Services

There are many forms of metal grinding and metal sanding, and GTR Manufacturing performs them all with perfection. Sometimes referred to as “time-saving,” metal sanding is generally used to remove burrs and scratches from mill stock material after it is punched or laser cut. In some cases, it’s used to change the original grain of the material to eliminate cracking during forming. Sanding also acts as a decorative finish and helps to plate and paint adhere better to the sheet metal parts. Both wet and dry sanding processes are available at our manufacturing facility. Dry sanding is more time-efficient and removes more material, while wet sanding is a better choice for our customers who are looking for a smooth finish.

In contrast, metal grinding traditionally removes welds, deburr metals, and creates smooth edges. Grinding also can be used to add cosmetic services to metal products, such as straight grain or orbital finishes. Both techniques are beneficial in the production of great-looking, quality parts.

Engineering & Design Support

GTR Manufacturing’s experienced engineering department can provide concepts, design changes, product enhancements, and reverse engineering. We will work with your team to deliver your parts at competitive costs.

Our sales, management, and engineering teams have experience in a wide range of industries and understand the changing needs of all of them. We work in close partnership with our clients in developing and refining product designs and production process planning to simplify manufacturing and create cost savings for your end product.

We have the capability to import and unfold your 3D models ( .dwg, .step, .iges, .sldasm, .ldprt, .dxf) built in Solid Works, Pro/E, and other modeling software. The model is unfolded and downloaded directly into the CAM process, reducing errors and assisting in short lead times for your sheet metal parts.



By using the Just-In-Time (JIT) inventory strategy, GTR Manufacturing schedules production to meet your ordering needs. We reduce costs by carrying less idle inventory, resulting in a quality product that is delivered on time at a lower price.

We pair JIT with the Kanban technique to manage our highly-efficient development process. We establish minimum and maximum quantities, fulfilling customer needs on a pull system. This method empowers us to reduce inventory for customers and suppliers and uses lean production practices. In addition, we have full insight into your pipeline through an online portal, ensuring it’s always full.

Are GTR’s Metal Grinding & Sanding Services Right For Your Next Project?

  • Is your business in need of grinding or sanding processes that adhere to specific requirements?
  • Have other manufacturers looked at your blueprints and ruled that your systems are “too difficult” or complicated to create?
  • Are you looking for a straightforward job but are surprised at how long the lead times are?

We are proud to simplify the precision sheet metal manufacturing processes by offering metal grinding and sanding as part of our one-stop-shop capabilities to speed up project timelines and lower the risk associated with relying on external supply chains. With complete oversight and control over the entire production process—from prototyping to shipping—GTR ensures uncompromised, on-time quality and delivery.
