Steel Fabricating and Finishing
Steel fabricating is a value added process that involves the construction of machines and structures from various raw materials. PGI has 20,000 square feet of custom steel fabricating space under crane and offers a variety of services for your custom steel project including:
Machine Platforms & Plates
PGI manufactures custom steel machine platforms and plates. Rather than placing new machinery upon a bare concrete floor, machine manufacturers may recommend mounting large manufacturing equipment onto a machine base or a floor plate. A steel platform serves as a precise foundation for the attached apparatus in addition to serving as structural support for the concrete foundation. Many times, these machine platforms have pre-drilled holes for mounting to a concrete floor. The bulk of the cut-outs and drilled holes serve to mount the machine onto the plate.
A heavy machine might be specified to be built upon a pre-fabricated, precision steel table or base. When a machined plate supports the resting machinery, the equipment can be worked on from below, increasing clearances, while hydraulic fluid reservoirs, coolant hoses, and electrification can be routed from beneath.
Machine Bases & Steel Tables
Our Blanchard Grinders can handle plates up to 14,000 lbs. with a maximum 128″ corner-to-corner swing. Our close tolerance surface grinders can reach 30″h x 36 “x 197” at:
- ± 0.001″ parallelism tolerances
- ± 0.002″ per foot flatness requirements
- ± 0.001″ thickness requirements
With some of the largest grinders in the country, we offer Blanchard and surface grinding services and routine maintenance services for select steel mills, machine shops, and steel fabricators.

What is Metal Fabricating and Finishing?
Metal fabrication is the fabrication of metal by cutting, bending, and assembling processes:
- Cutting is done by sawing, shearing, or chiseling (all with manual and powered variants); torching with handheld torches (such as oxy-fuel torches or plasma torches); and via CNC cutters (using a laser, mill bits, torch, or water jet).
- Bending is done by hammering (manual or powered) or via press brakes and similar tools.
- Assembling (joining of the pieces) is done by welding, binding with adhesives, riveting, threaded fasteners, or even yet more bending in the form of a crimped seam. Structural steel and sheet metal are the usual starting materials for metal fabrication, along with the welding wire, flux, and fasteners that will join the cut pieces. As with other manufacturing processes, both human labor and automation are commonly used. The product resulting from fabrication may be called a fabrication.
