  • The Custom Stainless Job You Must See

    Stainless steel is among the most durable materials to use, with its ability to resist corrosion, fire, heat damage and harm from chemicals; its hygienic advantages, providing an easily cleanable surface; its natural strength–which allows it to be used in a reduced thickness, which also provides the added cost benefit; and the ease with which it can be cut, welded, machined and fabricated.These are the main reasons we recommend the material for custom fabrications, whether it’s a small custom basket strainer (see the image to the right) for a healthcare facility or a specially fabricated commercial kitchen.

    You may already know about the benefits of stainless steel. But did you know that our Commercial & Industrial sales team specializes in custom stainless jobs? We can measure and recommend the ideal construction to suit your job.

    As an example, a local university’s facilities department struggled with ongoing maintenance costs in connection with bathroom vanities it offered in dormitories. The maintenance team found they were replacing a faucet every couple years, but more troublesome, the students were damaging the cabinet doors, laminated surfaces and just about every corner or edge. The solution: a set of custom fabricated stainless steel cabinets.

    If you look carefully at these photos, you’ll see every surface is stainless, with the exception of the tops. The countertops and sink bowls are a solid surface Corian material, which is a non-porous, stain-resistant stone-like material that can be shaped, carved, molded and textured innumerable ways. The best part about Corian is that it can be renewed; marks and scratches can be sanded off to give it an original appearance.

    We considered every detail in preparing this job. As you can see in the picture at right, even the drawers were fabricated with an attention to usability, with smooth corners, stainless inserts and heavy duty stainless tracks. And, again, for each edge and corner, nary a sharp to be found.

    The end result, beyond a beautiful product, was a very satisfied customer. The facilities department determined they would recoup their investment in due course, thanks to drastically reduced maintenance costs. On top of that, the parents and students were happy with a smart looking vanity that gave the room a refreshed and fashionable look.

    If you have questions about these vanities, or for your next specialized job, call us at Duff.

  • Summertime: Time to Think about Heating Season

    Heating Pre-Season Checklist

    The heat wave is over (for now), and we’re halfway through the last month of Summer. I know people are still at the beach, playing sports outdoors and enjoying being outside.  But with the end of summer in sight (sorry!), this is the best time for a pre-season tune-up. C’mon, you know the calls will come:

    • “I know it’s still September, but why is it so cold in here?”
    • “Why isn’t the boiler making any heat?”
    • “How much are we losing on that failed open steam trap?”

    Not only is it important to get ahead of a problem before it begins, but it also may be cost effective. That’s because we’re having a pre-season sale on heating specialties.

    Everything is on sale–from Alpha circulator pumps to Zeston fittings, and everything in between.

    If you want to learn about the steam regulating valves, steam traps and circulating pumps that we stock, explore our Plumbing & HVAC Pumps webpage.
