Steel, Plate, and Sheet Metal Fabrication

Our employees are fabricators, not machine operators. They can work with samples, sketches, or formal blueprints. While each has a specific area of expertise, cross-training provides not only the ability to utilize different fabrication methods, but also understand and compliment the process flow on the shop floor. This means:

• Not only do our fabricators inspect their own work, they also inspect the work of their co-workers.  Couple that with a final, overall inspection done by supervision, and you have quality you can count on.
• We keep our overhead low to provide you the most for your money.
• Since our workforce is highly flexible, each can fill in for the other in the event of scheduling issues, vacations, illnesses, and other unforeseen situations.  This means your products will get to you when you need them.
• Our business has been in existence under family ownership for over 100 years, through good times and bad.  

What we offer . . .

• Whether you provide a concept, sample, sketch,or formal drawing, we can help in the design development process.  Onsite consultation is available for local clients.  Since we have intimate knowledge of the production processes, we can help develop your product to satisfy your needs at an affordable price.  Design for manufacturing is what we do.
• Often, you only need a prototype or a few pieces to test, qualify a product, or fix a broken part.  This is what we specialize in.  We can cut through the red tape and get you back up and running or to market quickly.  If you require more detailed documented process, we can fulfill your needs as well.
• We provide short to medium-run production capabilities.  We do not claim to be a high volume shop and will not sacrifice our speed and agility in exchange for dedicated, high volume production.  
• Every business eventually has facility repairs or upgrades which require custom fabricated sheet metal parts.
• We can take your project from start to finish.  We maintain an extensive inventory of raw materials of various grades.  All the required equipment is in-house from shearing, cutting, punching, and bending to welding, assembly, and painting.  If there are any outside processing needs, we have a network of certified sub-suppliers to get the job done.
