Why the Trade Chooses PDC
We’re not a middleman with a catalogue. We’re door engineers who became manufacturers. Here’s what that means for you. One supplier, less hassle. Automatic door parts, manual door parts, safety barriers, sensors, operators – we cover more ground than anyone else. One account, one phone call, one delivery.
Obsolete? Not for us. When a manufacturer discontinues a part, your customer’s door is stuck. We manufacture in-house – send us the old part or a drawing, and we’ll make it. No excuses, no “sorry, it’s obsolete.” Competitive trade pricing. You’re running a business. So are we. We keep our costs lean and pass that on. Trade accounts get discounted rates – ask when you call. Free technical support.
