Quadra Trading Corp

About Us
Surplus Center now owns all of Quadra Trading Corp's inventory. We will be happy to help you with Quadra or Surplus Center's inventory.

Surplus Center is a warehouse distributor for many top name manufacturers. Manufacturers such as Parker Hydraulics, Hypro Pumps, and Prince Hydraulics, to name a few. All are brand new items direct from the factory with full warranty and at considerable savings.

We also offer surplus equipment in a variety of categories. We buy large quantities of manufacturer's surplus or excess stock. Surplus inventory is usually due to manufacturers design changes, business closings or inventory adjustments. Often these are priced at only a fraction of normal cost. A few surplus items we offer are used but reconditioned, tested and guaranteed by us. All used/reconditioned items are noted as such in the item description.
Have Inventory to Sell?
We are always looking for clean unused inventories. If you have over-stock or slow moving merchandise, contact us at buyer@surpluscenter.com.
